0:14
on what you said 70% of what you said
0:17
was really produced by
0:19
AI I'm and AI told you that right and AI
0:22
told me that right did I tell you I was
0:26
uh interviewed by an AI bot for a
0:28
podcast wow what was that like it was
0:31
interesting wait hold up we got nil the
0:33
in the
0:37
building even have introductions yet
0:39

0:48
people how you pack this many people in
0:51
this room this is a light this is
0:53
actually a light day this is a light day
0:54
this is a light day Man Neil degrass
0:56
Tyson I like saying your whole name it's
0:58
powerful you have to that's it deg grass
1:01
Tyson yeah there you go I love it man
1:04
how youall doing good see man degrass
1:06
Tyson is here he got a new book to
1:07
infinity and beyond which is out now
1:10
right that's out yeah it was on New York
1:12
Times bestseller it debuted number four
1:14
on the New York Times bestseller
1:16
bestselling author man come on man now I
1:19
like that I love it Flex on them nil oh
1:23
I'm just saying you know so how would
1:25
you describe
1:26
synchronicity synchronicity yeah that's
1:29
like like Earth I mean but by the way
1:32
nothing is synchronous in the universe
1:34
okay because relativity prevents that
1:37
break that down okay what two things two
1:39
events that you experience
1:40
simultaneously to another person who is
1:43
moving and they don't even have to know
1:45
that they're moving those two events are
1:46
not synchronous right one will happen
1:49
before the other and you can construct
1:51
it so that the reverse of that happens
1:54
so simultaneity is not a thing in in the
1:58
universe sorry I'm using the word
2:00
synchronicity two things can happen in
2:04
synchronously sure but the way people
2:07
the New Age movement has been using it
2:09
I'm I'm I don't know I can't no this
2:12
just sounds so like it's so much like it
2:15
people are getting pieces of bits of
2:17
information and become an experts well
2:19
well so this is I I what I said in I had
2:22
a I had a uh a video for um what them
2:25
people called uh podcast no no no no it
2:29
was where you give a whole thing talk
2:31
tag talk no no close close the hell you
2:34
do we're getting there we're getting
2:36
we're getting there master class only
2:39
F not
2:41
[Music]
2:44
only I hate you for only fans and you
2:47
get a little bit of extra mind talk
2:49
right right let's strip the mind so
2:52
Master CL I I made a point in the in the
2:55
it's in the trailer for it I say one of
2:57
the great challenges we face is knowing
3:00
enough about a subject to think you're
3:04
right but not enough about the subject
3:07
to know you're wrong oh that was deep so
3:11
many people are in this little Valley
3:14
uhhuh they do a couple hours of research
3:16
on YouTube and they'll come out thinking
3:18
like they're experts and then an expert
3:21
actually says they're wrong and they
3:22
can't they can't relate to that they can
3:24
relate to that right right no no by the
3:27
way as an educator I like the idea that
3:29
people like feeling like they're experts
3:32
that's a good place to start it means
3:34
you want to know believe you know
3:36
something and so I don't want to fault
3:38
people for the feeling that they have
3:41
when they know a little bit of something
3:43
but they've got to be humble enough to
3:46
recognize that whatever you know it
3:49
might not be as much as you could
3:51
know okay here we go B onass so can I
3:55
give an example I'm going to give an
3:56
example and it involves wormholes Maybe
3:59
ask you a little early is this too early
4:01
for Wormhole we was going to wormholes
4:04
okay I don't want to take it too early
4:06
let's slip it slide go down so I was
4:08
once at North Carolina's um Charlotte
4:11
Airport okay big airport and I had to go
4:14
from a big plane to a little plane and I
4:17
swear I walked like three miles inside
4:20
it was probably only a mile but it felt
4:21
like three miles and and my luggage
4:23
didn't have wheels it was like one of
4:24
these garment bags in my backpack and I
4:26
was like what what and I finally get to
4:29
my
4:31
and then I thought I'd be clever and so
4:34
I tweeted back when it was called
4:35
Twitter uh I tweeted this is my geek
4:38
tweet I said can't wait till we have
4:40
wormholes then all Gates will be
4:44
adjacent to one
4:46
another okay I thought I'm proud of
4:49
myself for that that's that's a good PR
4:51
good that's a good one well he knows so
4:56
however geeky you are you must recognize
4:59
that the geek spectrum is infinite
5:02
there's always someone geekier than you
5:04
so someone in the comment thread wrote
5:07
Dr Tyson the day we have wormholes you
5:10
won't need airports
5:15
oh one of your
5:18
students it was
5:22
like match and I lost that one out GE
5:25
you I out GE so listen this is an
5:28
Incredible Book um just to sit and just
5:32
disappear in this book oh thank you for
5:34
that cuz that is the the goal yo and
5:37
it's so it's so you the way it's
5:40
written it's it's plus it's a beautiful
5:43
book it's co-produced with National
5:45
Geographic yes oh you got a camera you
5:46
got the camera on this naal too bad for
5:49
all y'all just listening to this but
5:51
it's a really beautiful book uh and it's
5:53
co-produced with National Geographic so
5:54
you know they don't make ugly books you
5:56
know um it's fully Illustrated and I
6:00
think it's a fun read to get to get
6:01
absorbed into absolutely one of the
6:03
things but you know what they did they
6:05
they gave me a necktie that has this
6:06
pattern on it oh man you coord with your
6:10
butt I was going to wear it in here but
6:11
I was certain no one has ever worn a
6:13
necktie into this recording studio man
6:16
way to
6:17
marginalize thanks thanks Doc who was
6:20
the last person award tie him Mike Muse
6:23
Mike
6:23
m that was Monday he works with Morning
6:28
America okay that was
6:30
uh BB go ahead jump me so I've been
6:32
thinking I was going to say was if I
6:33
wear the tie what I want to do is wear
6:35
it on like a red carpet and you know on
6:37
the red carpet they ask you who you
6:39
wearing and I say I'm wearing my own
6:41
book
6:43
[ __ ] [ __ ] you got to end it like that
6:48
you better make that a clip Drew no
6:51
no Neil I've been uh i' I've been doing
6:54
my my geeky uh you know everybody's got
6:57
a soft geek underbelly somewhere my
6:58
geeky due dilig and um so I was watching
7:01
one of those videos that puts the Scale
7:02
of the Universe into perspective AR they
7:04
good they're good and the thing that
7:06
caught my attention was that when they
7:08
got done you know showing you the size
7:09
of the planets and all these other
7:10
things and black holes and all that
7:12
stuff but it was saying that there's
7:13
supposedly the thought is that there's
7:15
going to be a point where nothing will
7:17
exist everything is just going to go
7:18
like a black hell is just going to
7:19
swallow everything up but will time
7:21
still exist even when there's nothing no
7:23
no molecules no Dark Matter none of that
7:26
well time still move forward that's a
7:27
great question so there's a point in the
7:28
future where everything is gone
7:31
basically okay uh it we we we reduce to
7:35
base particles the black holes will
7:36
evaporate and there's no source of
7:39
energy to drive any action or phenomenon
7:43
or events okay so you can ask what
7:45
happens to time well what is time to us
7:48
it's it's a measurement of an interval
7:51
between two events we measure that and
7:55
we call that
7:56
time what are we using to measure it we
7:58
using like a watch that you wound up or
8:01
there's a battery something is
8:04
repeating there's a VI in the limit
8:06
there's the vibrating Atom from the
8:08
atomic CCM clock but something's
8:11
repeating the the the sweep secondhand
8:13
repeats the the the crystals in your
8:16
digital watch vibrate in a future where
8:19
nothing vibrates and nothing repeats and
8:23
nothing goes back on
8:25
itself the concept of the measurement of
8:28
time would have no meaning
8:30
but you'd still be able to say from your
8:32
view that one thing happened after
8:34
another thing so you can sequence things
8:37
but you wouldn't be able to measure any
8:40
interval of quote time that would occur
8:42
between them so just because every time
8:45
you measure time you're using something
8:46
that vibrates or repeats or has a rhythm
8:49
to it is it the rotating Earth Earth
8:51
around the Sun you measure days years
8:53
months seconds moments heartbeats it's
8:57
repeating take away all repeating
8:59
phenomen in the universe you have no way
9:01
to measure time wow you you have a quote
9:03
in this book and I'm going to destroy
9:06
it I'm going to say that in advance but
9:09
it what you're talking book is sitting
9:10
right in front of but I ain't going to
9:11
find the okay somewhere buy this some
9:16
stickies STI rather mess it up I I want
9:19
to mess buy this boy some stickies okay
9:22
so so it was
9:25
C I'm not gonna find no no I'll find go
9:27
go ahead Albert Einstein uhhuh said uh
9:30
those who believe in physics um what was
9:34
it people who believe in physics know
9:36
that the distinct the distinction
9:38
between the past the present and the
9:40
future are stubbornly passionately
9:43
passionate
9:45
Illusions so I'm I blew it but it's in
9:47
your book okay yeah you did okay and it
9:50
makes sense still you did okay that he
9:53
said you so let me let me offer a quote
9:55
of my own and then I'll get into the
9:57
Einstein quote so we we are prisoners of
10:02
the present forever
10:04
transitioning between our inaccessible
10:07
past and our unknowable
10:11
future with
10:12
Einstein because so you have a past and
10:16
a present and a future but someone else
10:18
in Motion in the universe their
10:21
Reckoning of that timeline can and will
10:24
be different from yours so what feels
10:27
like absolute understanding of the the
10:29
world through your perspective someone
10:32
else will completely disagree with that
10:34
and they will be perfectly legitimate in
10:36
doing so so the it's not so much an
10:39
illusion that's a good word to get you
10:41
riled it's just your point of view and
10:46
what relativity tells you is there's a
10:48
limit to how much you can or should
10:51
invest in your own point of view when
10:54
you're trying to talk to someone else
10:56
about their point of view there's a lot
10:58
to learn from that even I mean just
10:59
culturally and socially yeah this is
11:01
good for Drake and Joe Buon yeah
11:06
yeah so just because you have a reality
11:10
that you Embrace uh it might not be an
11:13
objective reality that then would apply
11:15
to others so be be humble enough about
11:18
that I Love This Man Neil degrass Tyson
11:21
is hanging out with us on social media
11:24
on social media if you express an
11:26
opinion people jump all over it and in
11:29
in the day am I am I overthinking this
11:32
in the past if you had an opinion that
11:34
differed from someone else oh tell me
11:36
more oh why do you think that way I
11:37
think this okay now let's go have a beer
11:40
was an exchange an exchange that is not
11:42
what's happening today today you put out
11:44
an opinion people attack it and I say to
11:48
myself are you attacking it because you
11:50
want everyone else to have exactly your
11:53
same opinion that's a different Society
11:57
okay that's a dictatorship with one
12:00
Doctrine all right and everybody is the
12:02
same part of what makes this country
12:05
beautiful is that which is beautiful is
12:08
be it's so many different people are
12:10
here and they all got different views
12:12
and we can celebrate that not try to
12:14
homogenize it oh man Mike you want to
12:18
jump in here you like this guy you
12:21
know this guy is amazing right I'm I'm
12:24
so happy he said what he said about
12:25
social media and I think
12:27
it's I hate social media
12:29
social media there not even so much
12:31
about the opinions in in the perspective
12:32
what you're talking about and the reason
12:34
why it fails them is because they're
12:36
looking for Varity they're looking to go
12:38
viral they're looking for a moment
12:39
they're looking to get the clicks and
12:41
likes up so even their statement isn't
12:42
rooted in sound facts and data which
12:44
they know um I love how you said
12:46
illusion that's giving them credit that
12:48
I don't know that everyone would but
12:50
what you're saying is they know better
12:52
but they just want they want want the
12:54
likes it's different celebrity is
12:55
different everyone can be a celebrity
12:56
now right everyone can have a platform
12:58
in the microphone M yeah all right no
13:00
deg grass Tyson is here I'm open up the
13:02
phone lines 888 742
13:04
3345 anything about the universe you can
13:08
ask him try to stump him anything are
13:12
are we because of our challenges with
13:14
gravity and our constant quest to escape
13:18
the planet Earth uh-huh are we really in
13:22
actuality prisoners of this planet okay
13:25
very good question so this book to
13:27
infinity and beyond is all about that
13:29
it's all about what was going on we were
13:33
standing on Earth flat-footed looking up
13:36
and saying I want to go to the Moon if
13:38
it's 400 years ago how would you do
13:41
that how is it do you do you you have
13:45
sailing vessels that go the ocean is
13:47
there sailing vessel that can move
13:48
through the air and take you to the Moon
13:51
well not really Icarus tried it built
13:54
wings and they melted got too close to
13:56
the Sun got too close to the Sun so do
13:58
you give up would you say I'm going to
14:00
still try this I'm just not going to
14:01
make my wings out of wax right so you
14:03
build on other mistakes so this is an
14:06
Ascent yes the quest to understand all
14:10
that which is above our head literally
14:12
and figuratively is an extraordinary
14:15
Journey that we made from the first
14:18
aeronauts people who figured out that
14:20
hot air can rise you can make a balloon
14:22
you know the first aeronauts was a a
14:24
sheep a duck and a chicken okay so the
14:27
people knew better they're not going to
14:28
send their own ass
14:31
I don't feel bad for the Sheep cuz if
14:32
the balloon failed at least the duck and
14:34
the chicken have a chance of Landing
14:36
smoothly right not the Sheep but but
14:39
anyway we you take this we've been to
14:40
the moon but our minds and our robotic
14:44
emissaries have been beyond that and
14:46
currently we're wondering are there
14:48
other universes so there's no end that's
14:49
why you infinity and beyond there's no
14:52
end to this is there any proof that um
14:57
you know we've been seeing these said
14:59
Mike hates when I bring this up too by
15:00
the way yeah here we go but why do you
15:03
suppose we're hearing all this UFO
15:05
conversation right now I I I I I don't
15:08
joke with it no more I used to joke
15:10
about it until you came here and said
15:11
show me the body y they so they put the
15:13
bodies out in Mexico it's great I love
15:16
it are those real I don't know if
15:18
they're real but it's that's better than
15:20
what the dude did in our Congress
15:22
because that was the Mexican Congress
15:23
dude didn't he said I got aliens but
15:25
they're in a lock box and no one can see
15:28
it that's not helpful okay so I I that's
15:32
not how science works when we brought
15:34
moon rocks back from the Moon it was
15:36
share with all the Laboratories of the
15:38
world yeah here's something we found you
15:40
all investigate it we'll do our test and
15:42
we'll compare okay so that's how science
15:45
works it's not one person giving one
15:47
result especially if it's an
15:49
extraordinary result you need
15:51
verification that is how you would
15:53
establish an objective truth in this
15:55
world a scientific result gets tested by
15:59
others even competitors and when they
16:02
all get about the same answer you say we
16:03
got a new truth on our hands so send
16:05
them alien B to scoop out some of its
16:08
flesh send it around to biophysicists
16:10
around the world then maybe they're real
16:12
I I I'm skeptical but that's
16:15
normal okay so yeah and all the the
16:18
fuzzy things in the sky do you know how
16:21
do you know a a say it with me a billion
16:25
photos are uploaded to the internet
16:27
every day taken by a smartphone and
16:29
their high resolution high resolution
16:32
camera video and and none of them are
16:35
aliens they're fuzzy things in the sky
16:37
but we have perfect images of each other
16:40
a million people are airborne at any
16:43
given moment with a window right next to
16:46
them don't you think if the mothership
16:48
showed up somebody would have a picture
16:50
of that in higher resolution than just
16:52
fuzzy lights across the sky so maybe all
16:55
these fuzzy lights are aliens and then I
16:58
I posted this people didn't appreciate
17:00
it I said I said no here's what I said
17:02
here what I said no here stay with me
17:04
stay with me I said
17:07
maybe aliens are actually
17:13
fuzzy and special affection for the US
17:17
Navy
17:19
okay that would explain everything all
17:21
of the fuzz okay I have a baby geek
17:25
question so baby we've been it is baby
17:28
geek cuz I'm not a geek person at all
17:30
but do the clocks have to go back this
17:32
year yeah so a baby geek it is baby
17:36
because first they said they didn't then
17:38
they said they didn't tell tell us yeah
17:41
I you know I could take her leave
17:43
daylight saving time I don't you know I
17:47
my wife is from Alaska just think this
17:49
through she's from Alaska the farther
17:51
away from the equator you go towards
17:54
either of the polls
17:57
the big bigger is the time
18:01
difference between sunset in the winter
18:05
and sunset in the summer so in other
18:08
words if you're on the equator it's 12
18:10
hours a day 12 hours of night every day
18:12
of the year okay as you go towards the
18:16
poles the hours of sunlight in the
18:18
summer get longer and longer and the
18:20
hours of darkness in the winter get
18:23
longer and longer so the so your
18:25
relationship to the sun is way wider
18:29
than any one hour shift would ever
18:31
matter to you okay so my wife went to
18:34
school in the dark in the winter the Sun
18:38
would rise at like 10:30 damn and set at
18:42
like
18:43
3:00 okay what is Shifting one hour
18:46
going to do for you nothing okay so it's
18:49
a it's an interesting gesture it's a a
18:53
tip towards when we needed sunlight to
18:55
illuminate the end of the day think
18:58
about we've only had electricity for 110
19:00
years yeah think about that after before
19:03
that we were burning some kind of fuel
19:06
be it whale oil or candles inside the
19:08
and so they said well let's put some
19:10
extra sunlight in the evening but then
19:12
you ask yourself why do that in the
19:14
summer and not in the winter when you
19:16
actually need the extra sunlight more so
19:18
I don't I'm not I'm not going to launch
19:21
a movement but if they're going to get
19:22
rid of it I you'll get no complaint from
19:24
me there you go oh man doctor oh by the
19:27
way one other thing if you ever writing
19:30
uh eastern Daylight Time Eastern
19:31
Standard Time just don't just say ET ET
19:35
yeah yeah I get
19:38
that that way whether it's daylight time
19:41
or Standard Time your time you give is
19:44
correct if you know what the time is
19:45
nobody remembers when the clock switch
19:47
over anymore so just say Eastern Time
19:50
etct PT Mt that's all leave out the
19:53
middle most of the time you'll get it
19:55
wrong when you're near the transition
19:57
but you you know what time it day you're
19:58
going to have lunch okay you're not
20:00
going to be confused everybody knows
20:02
when to switch the clocks and if you
20:04
switch the clock uh before during or
20:07
after you just say ET it's works man all
20:10
right man Dr Neil Tyson is a new book to
20:13
infinity and beyond and Beyond a journey
20:15
of cosmic Discovery this book this oh S
20:18
I keep hit the table I shouldn't hit the
20:19
table it hit the microphone oh Lindsay
20:22
Nicks Walker she's a longtime um
20:24
producer of the my podcast Star Talk
20:27
love this this is the third book in the
20:30
collaboration of my podcast with
20:31
National Geographic she's a longtime
20:33
producer she was editor of the previous
20:36
Star Talk book I say time to make this
20:38
woman co-author yeah and so she very um
20:41
enthusiastic she cut her teeth as a as a
20:44
people still say cut their teeth they
20:46
understand that you what you meant no I
20:47
said to someone they didn't know what I
20:48
was talking about how old how old were
20:50
they yeah were young yeah yeah okay yeah
20:52
so they cut their teeth on um she used
20:57
she was a journalist on and wrote on
21:00
biology and exobiology for NASA so she's
21:03
got good science chops good and so she
21:05
came in and we we co-wrote this and so I
21:08
was Del beautiful book man make sure you
21:10
get this book we got a lot of callers oh
21:12
yeah let's do it right sorry I don't
21:13
want to take time no no no no no Mike go
21:16
ahead real quick let me get Mike and
21:17
Tracy in real quick real quick yeah I
21:19
think that science is having such a
21:21
great moment right now and so I'm just
21:23
curious like what gets you up in the
21:25
morning what are you curious to study
21:27
and discover it can be more than one
21:29
thing it doesn't be the thing can I
21:31
answer a different question like what
21:33
keeps me awake at night I said get up in
21:35
the morning what are you excited for
21:38
right but I want to tell you what keeps
21:39
me awake at night can you answer get you
21:40
up in the morning too okay do both I'll
21:42
do both okay what keeps me awake at
21:44
night is
21:46
wondering whether the human mind is
21:49
smart
21:50
enough to even answer the questions
21:53
we've
21:55
posed or worse yet are we smart enough
22:00
to even know what questions to
22:03
ask so what gets me up in the morning is
22:07
applying my intellect to unsolved
22:11
problems my intellect built on the
22:13
efforts of generations of scientists
22:16
before me and I wonder is it sufficient
22:19
how clever do I have to be to get to the
22:22
bottom of what nature is trying to
22:24
reveal to us we don't know dark matter
22:27
we don't know what dark we can can
22:28
measure it we don't know what they're
22:29
made of we don't know was around before
22:30
the Big Bang but there's a profound we
22:32
don't know how we went from organic
22:34
molecules to self-replicating life on
22:37
Earth these for me are the four most
22:39
profound questions that science
22:41
confronts today and the frontier of
22:43
science there's other science like the
22:45
next round of medicines and this sort of
22:47
thing that's got to happen regardless
22:49
but yeah I I want to know what Quantum
22:51
Computing will do for us once that once
22:55
that hits the you know comes in the
22:57
house ankle never get sleep know what
22:59
worries
23:00
you how hard it's going to be for us I'm
23:02
not as worried about AI I'm not as
23:04
worried as some other people are I think
23:06
we'll keep it in check okay um so many
23:10
powerful Weaponry that we've developed
23:13
in the past yes it does damage and then
23:16
sane heads prevail and uh you know what
23:20
um who's that science fiction writer Ray
23:22
Bradberry when asked um why do you write
23:25
these Futures that are so Bleak does
23:27
this what you think we we will confront
23:31
and he said no I don't write them
23:32
because I think that's what will happen
23:34
to us I write them so you will know to
23:37
avoid
23:38
them oh wow so maybe movies like The
23:41
Matrix and Terminator
23:44
Terminator come on maybe that is these
23:48
are it's
23:50
writers giving us a
23:52
lesson and how to become wiser Shepherds
23:57
of the powers that we wield I like that
23:59
man Tracy jump in there so Neil to give
24:02
you um a madeup scenario right let's
24:06
just say that reincarnation Is the
24:09
destiny of Our Lives after death but you
24:13
are able to choose it's not necessary if
24:15
we figure out why we age at all then
24:18
you'd never die okay so that would
24:19
render reincarnation obsolete dang well
24:21
let's just say all that doesn't happen
24:23
and reincarnation is still present just
24:24
keep that in mind there are things that
24:26
can happen that render the previous
24:28
concern completely irrelevant like there
24:31
are people who are worried about the
24:32
buildup of manure in the streets of
24:35
Manhattan 10 years ago 120 years ago how
24:38
what are you gon to and flies went in it
24:40
and all the street vendors that sold
24:41
fish and other food because there no
24:43
supermarkets back then the Flies it was
24:45
a it was a it was a health Nightmare and
24:47
they're trying to think well what do we
24:49
feed the horse so it doesn't poop so
24:50
much or what do we feed it so flies
24:52
don't reproduce and brilliant people are
24:54
trying to solve that problem and the
24:56
actual solution was the car the car okay
24:58
okay just all right so now thank you
25:01
okay so reincarnation sticking with your
25:03
scenario thank you you know just let's
25:04
just assume the Divine intelligence
25:06
stumps us and reincarnation still
25:08
happens but you get the opportunity to
25:10
choose either to come back as a human
25:13
again or to come back as another living
25:15
organism plant kingdom Animal Kingdom in
25:17
between which one would you do well I'm
25:19
I'm so familiar with what it is to be
25:21
human I wouldn't trade it for other
25:23
animals especially since the life of
25:26
other animals is basically in our hands
25:28
uh I don't I don't want my life to be
25:31
subject to the whims of another species
25:34
uh and so yeah no I'd come back as a
25:37
human and I'd come back in the future I
25:39
wouldn't like go to the past if time
25:41
travel was part of The Reincarnation
25:43
package do you believe that humans are
25:45
of the higher intelligence I think we're
25:47
more intelligent than other than all
25:50
other creatures that have ever existed
25:52
but who decided that man we did right
25:57
right
25:59
so would aliens say that about us okay
26:03
here I got a quick story here I know you
26:05
got a agenda here no I just want to get
26:07
the call we good good ready I remember
26:10
being in school and Elementary School
26:14
I'm an old fart okay and so the teacher
26:18
says uh humans are the peak of The
26:22
evolutionary ladder this was back when
26:24
this is how they were talking and well
26:27
do we have the big brain well no we
26:30
don't we don't okay uh whales elephants
26:35
and porpuses have bigger brains okay so
26:37
it can't be that so oh if you take the
26:40
ratio of the weight of your body and the
26:43
weight of your
26:45
brain we do better than all other
26:48
animals this is what I was taught that's
26:50
what you was taught so that's how they
26:51
so your brain to the body that you're
26:53
controlling would we do good okay I
26:56
would later learn that that that's not
26:58
even true that's only true for
27:01
mammals and even at that we are just a
27:04
little bit higher than mice in the
27:07
weight of our brain relative to the
27:09
weight of our just a little bit higher
27:11
than mice so we're not it's not a
27:13
runaway hands down thing but you know
27:15
who has a way bigger well who a bigger
27:19
brain to body weight ratio are midsized
27:22
birds like crows
27:25
Eagles um uh uh owls that midsize birds
27:30
have a higher brain to body plus their
27:32
bodies don't weigh much because they fly
27:34
and their bones are Hollow okay so so
27:37
they have a brain and a and a body that
27:39
doesn't weigh all that much but they
27:40
don't win the category you know who wins
27:43
it are certain species of
27:47
ants ants and then you think about it
27:49
ants say yeah you're right look at that
27:50
big old head they came around at the
27:52
front of their body that big old head so
27:55
for some ants their brain is 20% their
27:57
body weight wow hea this is why I watch
28:00
National Geographic that just they don't
28:02
they get on me about that explain it
28:04
that
28:05
way tell us watch what you want to watch
28:09
let the man thank you let the man watch
28:12
what he got to watch so now watch so so
28:14
I'm thinking if aliens want if the
28:17
aliens are into
28:19
brains then we would not be their first
28:22
object of Interest here right if they're
28:24
into brains they'll talk to the whales
28:26
first and they'll know how to if they're
28:28
smart enough they'll know how to talk to
28:30
whale whales talk to each other with
28:32
okay uh they'll talk to the whales then
28:34
the elephants then the Dolphins then the
28:37
ants and then maybe the mice and then we
28:40
maybe we're
28:41
fifth okay that's how top five though by
28:46
the way all that was in my previous book
28:48
I ain't been here in two years you don't
28:50
write you don't true text that's not
28:52
true the book the book before this one
28:55
was called Star Messenger Cosmic
28:58
perspectives on
29:00
civilization this is every this is what
29:02
we look like when you come from out
29:05
there and this brain conversate this
29:08
brain thing and the and the aliens
29:09
that's in that book just to just so
29:12
before you get too big ego about your
29:14
life right that is and why is it that we
29:17
measure how smart an animal is by how
29:20
well it can do like chimpanzees how well
29:23
they can do sign language and things we
29:25
measure how smart they are by how well
29:27
they can talk to us rather than measure
29:30
how smart we are by how well we can talk
29:32
to
29:34
them come on man let me get to these
29:36
phone call to the grass he's on the road
29:38
he's flowing keep flowing I love it
29:41
throw a beat on underneath this dude he
29:43
dropping sway don't bring back the same
29:46
information when he watch these show I
29:48
tried I triy to say it just goes over
29:50
their
29:51
head oh that he just dissed y'all okay
29:54
uh listen that's why you're at this
29:55
other end of the table you come his head
29:58
anytime you could that's why it's
30:00
distance you know about
30:03
distance all right we got Isaac on the
30:05
line from illino welcome to the show
30:08
Isaac go for it
30:10
hey uh hey I'm 12 year old and I want to
30:15
know how does the universe expand with
30:17
gravity he's 12 oh excellent hey thanks
30:21
for having that those kind of thoughts
30:23
if you're having those kind of thoughts
30:24
are you building something in your
30:26
basement that your parents don't know
30:27
about
30:29
I'm just
30:32
checking
30:34
Poss maybe no snitching Neil no
30:37
snitching Neil okay
30:40
so he needs to finish the equation so he
30:42
just needs that there you go he's still
30:44
he needs some extra data so so the
30:47
universe is
30:49
expanding even though the collective
30:51
gravity of all the galaxies is trying to
30:54
slow that
30:55
down and it turns out there's this other
30:58
pressure in the vacuum of space that we
31:01
discovered now 25 years ago and a Nobel
31:05
Prize was awarded for it it's called
31:06
Dark Energy let me say that better Dark
31:10
Energy it is a pressure in the vacuum of
31:13
space operating as an anti-gravity force
31:16
that is making the expansion of the
31:18
universe accelerate and gravity is
31:21
helpless in the presence of this force
31:24
and we do not know what's causing it but
31:27
we can me measure that it's there so
31:29
yeah gravity is trying but it's failing
31:32
okay Isaac hey man you're a super
31:34
citizen Isaac hey remember we're on your
31:36
team all
31:38
right invention we love you Isa call his
31:43
school love you check his
31:48
backpack sounds scary man he hey shara's
31:52
on the line from Bakersville Shara go
31:54
ahead sha love you Isaac sorry
31:58
hello sherea you there Shar Shar I'm
32:02
here go for us uh say hi to Neil degrass
32:04
Tyson you got a
32:06
question yeah hi my question is do you
32:08
believe that the Universe has something
32:11
to do with um the laws of attraction
32:15
like thoughts are
32:17
things okay so so this whole kind thanks
32:20
for that question this whole notion of
32:22
Laws of Attraction uh that came out when
32:24
we finally understood magnets m okay and
32:28
they talk about animal magnetism where
32:30
do you attracted to someone and then
32:32
chemistry reached high levels and say
32:33
what's the chemistry between you we
32:35
started using these sciency words to
32:37
describe whether you like somebody or
32:39
not and but I'm not convinced that the
32:43
physics the chemistry matter when people
32:46
decide who they like and who they don't
32:48
like uh especially since half of all
32:50
marriages end in divorce so there can't
32:53
be anything fundamental about What
32:55
attracted you in the first place okay
32:57
and and they're people who hate each
32:59
other and end up liking each other so
33:01
I'm whereas magnets the North Pole will
33:03
always stick to the South Pole no matter
33:04
what so I'm I will I'm not go I'm not
33:10
gonna bring I'm not gonna bring the the
33:13
the science vocabulary into the very
33:16
complex dynamics of human interpersonal
33:19
Affairs okay Sharita yeah okay thank you
33:23
you're a citizen hey sh get his book
33:24
it's a great book by the way all right
33:26
you're CZ about something else
33:28
in the B book you you you go and you
33:31
talk about time
33:33
travel oh by the way all those places
33:35
where we there's a subject that where a
33:37
movie tried to deal with that subject
33:40
yeah I I I talk about that movie that's
33:42
like it's like the scenery along the
33:44
Journey of this book did they get it
33:46
right did they get it wrong and that's
33:48
the pop culture dimension of it because
33:50
my podcast Star Talk has three DNA
33:52
strands if I may one of them is science
33:55
another one is pop culture and the third
33:57
is humor and we find that if you make it
34:00
relevant by referencing pop culture and
34:02
person a person Smiles for having
34:05
encountered that they come back for more
34:06
yes that's what we try to do absolutely
34:09
so what so is time travel possible well
34:12
I mean travel is possible through time
34:14
zones but can we travel can we travel
34:17
I'll tell you something interesting
34:18
about time zones yeah you know time
34:20
zones and get me back on track after I
34:22
so time zones are these lines of
34:24
longitude on earth like orange slices
34:26
right and 24 time zones with a little
34:29
more cuz some some folks do half hour
34:32
time zone why don't get me started
34:35
that's so unnecessary but all right so
34:37
there it is but wait a minute all these
34:39
lines of
34:40
longitude
34:42
merge at the
34:44
pole well if lines of longitudes
34:46
separate time zones then what time is it
34:49
at the poll
34:52
polls the question has no meaning on
34:55
Earth the question has has no meeting
34:58
correct Earth corre because there's
34:59
there is no time because all time zones
35:01
meet so there can be no time as we
35:06
reckon it everywhere else on Earth so
35:08
Santa has no time he doesn't have a
35:10
clock he doesn't he doesn't hold a Rolex
35:13
or nothing a got a Rolex after all these
35:16
years of
35:17
worko one of
35:21
those dude makes the presents he makes
35:24
the Pres okay oh another little thing
35:25
about Santa anytime they show him in his
35:27
in his in his slate no no in his the
35:31
house the factory yeah work the workshop
35:33
oh yes um they'll show trees around
35:36
there and the mountains in the
35:36
background the North Pole is not on
35:40
land it's on it's a
35:43
floating ice glacier no well glaciers
35:47
would be on land it's ice I there is no
35:50
land there so what whever Santa is
35:53
making it it's on an ice flow for now
35:56
until all that ice melt else then Santa
36:00
hey
36:01
kids dude is Ru Santa's dressed in
36:04
winter clothes holidays if this global
36:06
warming stuff keeps up he gonna be in
36:08
bathing suit delivering presents that's
36:10
a great book Santa Santa in bathing suit
36:13
Santa
36:14
Speedo stop
36:16
that got
36:19
ail got a
36:22
visual so let me finish out so if you
36:24
want to go back in time uh no so so
36:28
you can go forward in time Einstein
36:29
relativity fully Embraces that okay
36:32
either by traveling fast or or sending
36:36
someone else to a high gravity field and
36:38
their time will go more slowly compared
36:40
to you they showed this in the movie
36:42
Interstellar Interstellar the boys went
36:44
down to the a black hole planet and they
36:47
were down there for like 20 minutes but
36:48
the guy up in the ship aged 10 20 years
36:51
so that's the relativity of time that
36:54
was also the best example of a black
36:55
hole I read as well right the
36:56
interstellar black you know why because
36:58
the co-executive producer is named Kip
37:02
Thorne who is an astrophysicist
37:05
specializing in cosmology has written
37:08
books on the subject and he won the
37:10
Nobel Prize for dis the discovery of
37:13
colliding black holes in the universe
37:15
that's the man you want at that level
37:18
doing that movie but they also deal with
37:21
time travel in interstellar at the end
37:23
oh at the end so then they they Ste
37:26
places where right where we're not
37:29
fantas the physics is a little fuzzy so
37:32
if it's
37:33
fuzzy there Al but but I got Christopher
37:37
Nolan directed that and he also did
37:39
Oppenheimer okay so Nolan me and Nolan I
37:42
had him a guest on my podcast he my
37:44
boy's got a got a geek belly like
37:47
there's none other oh I got listen to
37:49
that what about by way I Barbie heered
37:51
not that you asked oh nice yeah I saw
37:53
both movies the same day you got to get
37:56
ready you got to be mentally ready for
37:58
that yo first of all I love that you're
38:00
having I feel like you're having a great
38:02
time up here that's this is what I
38:03
always
38:05
want but you don't want to be able to
38:07
travel back in time because that's
38:09
dangerous and and
38:11
Hawking obviously before he died
38:13
suggested we might one day discover a
38:15
time travel conjecture okay where we
38:19
learn that you cannot travel backwards
38:21
in time because you then alter the
38:24
present from which you came yeah so if
38:27
you go back in time and prevent your
38:29
parents from meeting one another you
38:31
don't have to kill them that's
38:32
unnecessary okay just prevent them
38:34
meeting then you're never born you can
38:37
interrupt them having sex so they have
38:39
sex 10 minutes later than a different
38:42
sperm fertilizes the egg and someone
38:45
else other than you were born there a
38:47
lot of ways you could do the Terminator
38:49
scenario without killing everybody okay
38:51
so if you think that [ __ ] the
38:55
[ __ ] good one
38:59
best friend
39:00
Bo that's a good one
39:04
so wait wait wait so you so here's the
39:09
problem if you go back in time prevent
39:11
your parents from meeting each other
39:13
then you're never born so that you don't
39:16
exist to go back in time to prevent them
39:18
from meeting each other so this is very
39:21
paradoxical in that regard but the way I
39:23
think about it is let's say you let's
39:25
say you are um your friend is walking
39:27
down a corridor and they slip on a
39:29
banana peel and fall let's just say that
39:32
happens all right and you want to
39:33
prevent that and so there's a new
39:35
texting service that can send text
39:37
backwards in time in this new universe
39:39
and you send a text and you go backwards
39:41
in time to your friends say watch out
39:44
for the banana peel okay so what happens
39:47
the person is walking down the corridor
39:49
the text buzzes and they read it says
39:52
watch out for the banana peel and they
39:54
read that at the same time they slip on
39:56
the banana peel because they weren't
39:58
paying attention to their thing because
39:59
you made them not pay attention it's
40:01
like the Matrix with the
40:03
cookie that's what I'm saying so it
40:05
could be that your attempt to interfere
40:07
with the past is what made the present
40:09
the reality that you came from in the
40:10
first place and that's where we can
40:12
conclude our lecture today our lecture
40:14
hall by the one and only Dr Neil degrass
40:17
Tyson man it's not enough time for you
40:20
brother by the way my book a year ago
40:22
when you didn't call me that book has a
40:24
chapter you can't change the past d
40:29
that was good that was good okay no the
40:32
chapters in that book cuz it's about
40:35
civilization it's there's a chapter on
40:37
color and race gender and identity Law
40:40
and Order uh uh life and death body and
40:44
mind uh so there's all these subjects
40:47
that we've all thought about over
40:49
Thanksgiving dinner with crazy uncles
40:51
and and ants yet it's a cosmic
40:54
perspective on that in an attempt to
40:56
just level the plan field for all
40:58
conversation that that came out just a
41:00
year ago uh yeah you came here you did
41:02
everybody's show but ours I recall that
41:05
I didn't want to bring that up I didn't
41:07
want to go back into
41:09
time speak on it conjecture
41:14
conjecture maybe if you had came that
41:16
time you wouldn't be here
41:19
today never know man I'm just saying but
41:22
what we can celebrate is that you're
41:24
here in the present and we appreciate
41:26
you
41:28
appreciate it and I see you've been
41:29
going to the gym keep that going you
41:31
look good than you thank you man all
41:33
right you're the best I used to wrestle
41:36
so I know male bodies I know when you're
41:38
doing something with your body he told
41:39
you he was going to the gym no he didn't
41:41
have to I told I knew it you felt it no
41:44
I didn't touch I
41:47
tactically the cosmos I wrestled for 10
41:51
years yeah okay I was Captain of my high
41:53
school wrestling and before that you
41:54
were rowing at I also rode I danced too
41:58
and but but what I'm saying is I know
42:00
bodies and I know when when the bodies a
42:03
little more gaunt at the cheeks and the
42:04
throat and how people walk how they hold
42:06
themselves how how all of that and I
42:08
knew immediately when I last saw you
42:10
when last time I came through when I was
42:12
not on your show you came out out the
42:14
whole Corridor and I saw you yeah so
42:16
stay in shape it's good I'm going to the
42:18
