0:04

A sneaky bonus episode in your

0:06

podcast feed this week? Because on

0:09

Tuesday we were joined by Dave

0:11

Bailey of Glass Animals. So.

0:16

Day. You

0:20

might know the song it was a

0:23

previous hottest one hundred number one. And

0:25

not only is Dave a musician, he's

0:27

also a science bath and he's a

0:29

fan of the signs with duct to

0:31

call podcast David You listening? Hello. He

0:34

was in the country this week for a one

0:36

of show and alongside that. Said. I've

0:38

got some questions for call if he could pass these

0:40

on and we thought you know what? Not.

0:43

Only will we pass them on, but we

want to get you in stew. You're asking

0:47

doctor call these questions so that's what we

0:49

did and you're going to hear some of

0:51

them in this episode including Doctor Called talking

0:53

about the science in this song, Heat waves,

0:56

Not. Only this the video is going to be up

0:58

on you tube as well for you to see the

1:01

visual of what went down. So. Let's

1:03

do it right. Here on the signs it

1:05

to call podcast This is Dave Bailey of

1:07

Glass Animals Peking Duck to cause brain. So.seagal

1:12

This morning we have a

1:14

very special guest with us.

1:16

He's on our shores. Dave

1:19

from Glass Animals Dave home

1:21

to sign said Calve. I'm so

1:23

excited to be here! So you're a fan

1:25

of the part I will say and

1:27

how did you get across Science or

1:29

Dr. Karl Rove? What? Every time we've

1:31

come to Australia have heard whispers? Of.to

1:34

call you hear the name it

1:36

kind of flow summer and prefer

1:38

of Australia and. I. Looked

1:40

up or been listening to the For

1:42

Podcast and I'm. The. So. The.

1:45

Option to came up to be on. it was like

1:47

what of yes. Signed. Me up! You.

1:49

Have a stack of questions that

1:52

you have prepared. Yup, You

1:54

ready? Yeah, let's go. What

1:56

if gravity didn't exist? Will

1:59

First it'd be nothing heavier

2:01

into a villainous and hydrogen

2:03

helium. Are your plans they manufactured

2:05

in stars and the stars are drawn

2:07

together by gravity. Let me give you

2:09

a philosophical point of view is a

2:11

book by Martin Rees cold just six

2:13

numbers yeah and another one by Grant

2:15

Lose called Afforded Universe at a look

2:17

at what would happen if the certain

2:19

Constance was the fine structure constant or

2:21

pie which the little tiny bit different

2:23

and in a vast majority of the

2:25

universe is a play out the right

2:27

no laws. So. It is possible

2:29

to have a universe it was a be

2:31

No gravity and gravity goes back to John

2:34

Wheeler Mess tell space had a curve com

2:36

us and curved space tells mess where to

2:38

go to the first the is still be

2:40

no stars while heavy elements that it is

2:42

is there was an earth would immediately explode

2:44

with the grocery would have stopped because his

2:47

out would pressure to be no atmosphere only

2:49

the plaza the be no place because of

2:51

he nothing from the gravity point of view

2:53

of bringing things to give you any have

2:55

the electromagnetic force the strong nuclear force in

2:57

the week negro. For sports. Do.

3:00

You demeanor gravity woes and into that

3:02

that cause ignores dark matter Doc Nz.

3:05

Justice. System athletes

3:07

object so did nothing. What exists well as

3:09

the a different universe? Yes because why should

3:11

we Things that the laws that exist is

3:14

under you and me. I have read too

3:16

much sausage and solid image my brain so

3:18

I tend to think that stars could be

3:20

living creatures in a sense of the modeling

3:22

from the editors to spin this away networks

3:24

and this way that way is like one

3:26

or Norton the computer and a computer can

3:28

mimic or be intelligent and so in that

3:31

way a star could be a living creatures

3:33

and we would exist on the lifespan. So.

3:35

Small. We wouldn't realize it. It was alive

3:37

like a bacteria. one. your skin's doesn't realize

3:39

that your allies. Have a total

3:41

read to us on such as far as not

3:44

see what science fiction as by I saw of

3:46

leads me into question that comes out like which

3:48

is due. Aliens exist Yes and

3:50

no. At the moment we got

3:52

zero proof whatsoever. We have size

3:54

places with in our solar system

3:56

where we have underground oceans of

3:58

water. My. When in

4:01

two moons of Jupiter ah you get

4:03

a maiden Europa and two moons of

4:05

Saturn tarzan and insult us down. So

4:07

this is a big one because when

4:09

his Cassini spacecraft I mean to overran

4:11

is so this is sort of ready

4:13

to holler of like in six had

4:15

Sun sets it up up up up

4:17

up the digital particles and I ignored

4:19

them. Because. A big thing was the

4:21

rings, assassins and toss it and then I would back

4:23

him up at the records. I sort. What

4:26

way we've been running into a rocks

4:28

a things for to sixteen animators in

4:30

size and length and into his as

4:32

a bit into the made up and

4:34

allay an enemy disability of mid and

4:36

in the ass. A judge's where do

4:38

you get rock for to sixteenth nana

4:40

meters in size and animators? billions of

4:42

the yes and is it all from

4:44

hydrothermal vents. Nine. About how

4:46

to some of his day they happen at

4:48

the see Saw exactly. So let's see this

4:51

is mountain Range. Which is the biggest mountain

4:53

range on Earth. Yes, eighty seven kilometers long

4:55

and you'll never see it. Because

4:57

the base is therefore have kilometers down

5:00

and the top is about two kilometers

5:02

day our Mariana trench or that you

5:04

never see as she and other age

5:06

was wanting real the as like a

5:08

same on tennis balls and a five

5:10

hundred places with yours is falling apart

5:12

tectonic plate activity guess is hot water

5:14

coming out and a hot water is

5:16

of the thames up to four hundred

5:18

degrees c and that water the energy

5:21

supplies the Nz needed to run a

5:23

law system and the elements coming out.

5:25

Of. The elements of loss And so you

5:27

got these five hundred or south. The ecosystems

5:30

which it's like this. quick creases down the

5:32

like, wounds the diameter of your league and

5:34

two meters long without a mouse or an

5:36

aimless. Once. A has

5:39

stairs. The way they live is like

5:41

imagine that you. Had a

5:43

transparent panel on your tummy and dry up

5:45

in the sunlight and get sort synthesis happening

5:47

is kind of acquittals as he wouldn't need

5:49

of my dreams like Capella a chubby is

5:52

so that's what we did was we sound

5:54

so this is strong evidence it is hard

5:56

assume of in on his cell discuss the

5:58

what is coming out. The two

6:00

hundred cume is a second am

6:03

a two hundred kilograms seconds And

6:05

then last week was announced We

6:07

found some more particles that had

6:09

his frequency size range of around

6:11

one hundred and twenty and two

6:13

hundred and twenty nine images which

6:15

is the size range of to

6:17

bacteria that live on hydrothermal vents.

6:19

So do you have any proof

6:21

is lost. None to have suggestions.

6:23

Just south at the end of

6:25

every year the astrobiologists have a

6:27

conference saying who do you reckon

6:29

Stereo Tibet. Loss on any way it

6:31

ended the and they have a shelf

6:33

has who refuses was out there known

6:36

as able to the head up who

6:38

vacancies intelligent last that half with the

6:40

hands up Oregon is into left out

6:42

in the hearing that the you a

6:44

please in the American Congress and or

6:46

less what's the isn't As a Brian

6:48

Dunning was broadening movie he says gift

6:50

to a guy is K P T

6:53

O id the Us I movie they

6:55

don't want you to see and around

6:57

thirty five minutes is is got he

6:59

just completely. Demolished as at Healthy? Okay,

7:01

that is really very very interesting. Are

7:03

we that saw of? Brings me to

7:06

another question. How.

7:08

Long do we have left arm

7:10

you milking the extinction his last

7:12

and is a whole bunch of

7:14

different things. It's so on one

7:16

hand you looking at external natural

7:18

events and so in twenty six

7:20

doing on Halloween the Halloween asteroid

7:22

came past and it mister by

7:24

roughly the distance between the earth

7:27

and the moon. Oh excellent some

7:29

there's so much and it was

7:31

six hundred meters in diameter which

7:33

by coincidences as a diameter of

7:35

my plan us that you have

7:37

your own. Planets. Out,

7:40

spit it out. Ali is caught. So what are

7:42

yet? What? What I'd for one to crush on

7:44

a ski? How do you get one? Asked

7:47

your have friends. He

7:49

just went there for a flag and will

7:51

never do is in the asteroid belt a

7:53

six six two hundred meters in diameter is twins

7:56

Mars and Jupiter but his his head hit the

7:58

earth depending on where it hit. Are

8:00

you did hot? did geological hot of astride

8:02

it's or the middle of the pacific ocean?

8:04

All the little burnt out he kept it

8:06

would have killed between. Thirty

8:09

And Sixty Percent of All humans.

8:12

And we if we had three is

8:14

warning could have done something about it.

8:16

We had three weeks Ross so we

8:18

need to become a space going right

8:20

so we'll humans evolved. Definitely, we're not

8:23

going to make it past the a

8:25

billion years ago on earth was in

8:27

the surface temperature be hundred degrees c

8:29

and almost certainly we will evolve into

8:31

something South Korea come in more homophily.

8:33

Read the book by Freeman Dyson. disturb

8:35

the universe where he begins. The proper

8:38

safe for human is. A cloud

8:40

of I and vapor. The. Diameter of

8:42

a planet. Fifty. Kilograms sliding through

8:44

space and never getting and very important.

8:46

he still has six because as you

8:48

know the greatest philosopher whole time Frank

8:51

Zappa said oh yeah your main sexual

8:53

organs your brain know a squishy colored

8:55

bits as you brides as you go

8:58

to Brendan have sex and so that

9:00

that risk your worries about be able

9:02

to survive as a survivor so Oregon

9:04

will still survive but we won't Initially

9:07

bases carbon based bags that evolution is

9:09

left us with. While.

9:11

But we've got to get past the shorten things

9:13

like climate change and that lack of bio diversity in

9:16

the car race going and all that sort of

9:18

stuff. and we can do that. There's enough money

9:20

the will to do it's just a zebra in the

9:22

right place. This

9:25

is a bit of an Id question here. Entropy.

9:29

Entity. I think it's a it's. It.

9:31

Sucks. And. Like

9:33

as a law that everything goes

9:35

towards chaos like about is the

9:38

opposite were true. Why

9:40

is that true? Why I was like so when

9:42

you like drop your coffee is splat as everywhere

9:44

he goes all at by. If it if and

9:46

we didn't exist you might drop your coffee and

9:48

it would just stay. In. The cuts

9:50

and balance perfectly. Or. You could

9:52

walk through a field and then the various

9:54

Adams would come together to make the cup.

9:57

And the Adams's have your Nazi Jr and

9:59

the Kathleen. Q and in spontaneously form

10:01

themselves into a cup of coffee. was on.

10:03

You will says that failed as get why

10:05

Isn't that true? It could be. As I

10:08

said. A fortunate universe by grant

10:10

loose and just six zero and incentive

10:12

alternative universe is and in one of

10:14

them and we could go back with.

10:16

So what we've got is it we're

10:18

heading towards maximum disorder. So yes as

10:20

so energy comes into a system and

10:22

earner that is used to do something

10:24

but then somebody goes ways hates and

10:26

we're heading towards inexorably was called the

10:28

seat. This is universe. why wouldn't want

10:30

what we have into piece as just

10:32

the luck of the draw in the

10:34

universe. A we happened to be in

10:37

and party luck of the drone. Mom

10:40

I'm alive of Scott. Friends are very

10:42

like as as a hundred have a

10:44

very narrow boundaries and so we could

10:46

have universe in which interview with the

10:48

other way like you know have this

10:50

is probably like you bet this is

10:52

this how you bet the conservation of

10:54

energy yeah he has us allies or

10:56

was it gets caught in Nz is

10:58

conserved. Only in a

11:01

stationary universe. Oh. Speak

11:03

but we have. A universe is expanding now.

11:05

Imagine you get a rug between here and

11:07

a distant galaxy. And then that,

11:09

this and gals he's going to escape

11:11

away at about seventy kilometers per second

11:14

for every million passing. So yeah, yeah,

11:16

in hubble expansion rots, the rebel try

11:18

to get longer. Yeah so.

11:20

You can get india of it. Ah

11:22

energy is constant only in a stationary

11:25

universe and when on the stage for

11:27

users sets. our understanding is like a

11:29

child's on a beach picking up a

11:32

show and ah I understand everything there

11:34

is no that marine loss yes and

11:36

his whole energy at this and cause

11:39

as we know from those fun wonderful

11:41

movies made you still under water. But.

11:44

As we get to get one who's as. Though had tough

11:46

guy who does is getting i'm certain

11:48

says it's this. Is

11:50

a bit busy for his act is is

11:52

he says into that the as great as

11:54

guy any should have an aunt is a

11:57

yes I love it. I

12:00

was wondering if the whole population of us

12:02

can run in the same direction at the

12:04

same time? or stood on the same place

12:07

on earth the same time and jumps. What?

12:10

Would I would the Us like Spain or

12:12

like would a move. Or. If

12:14

everyone like when. In

12:16

the same direction, the same time

12:18

with a spinner or has do

12:20

a lot homework on this one

12:22

south cause I'm into a D.

12:24

Follow it's Casey Day know? ah

12:26

Xkcd. It's a web page design

12:28

to be unpronounceable by Randall Munroe,

12:30

an excellent Nasa engineer excise a

12:32

date so he did some stuff and

12:35

also the new scientists and it

12:37

comes down to numbers so we

12:39

humans way about half a billion

12:41

tons. Or of put together

12:43

the whole earth He is many thousands

12:45

of times about ten trillion times more

12:47

than that was set in my for

12:50

the Earth way but compared humans tend

12:52

to becomes more than asked to this

12:54

a of all the humans trying to

12:56

do something says you try to have

12:58

the humans or running wondering Since his

13:00

I were to run for ten years

13:03

the earth would have attendees end up

13:05

in a different place by listen one

13:07

tense as a sequence of the human

13:09

his you measured the change to the

13:11

surface hub. Is is that

13:13

about it? About the since the

13:15

last nice who nature bet three

13:18

weeks ago. So this is a

13:20

bunch of factors affecting the rotations.

13:22

Yes, Firstly, the is the. Tide.

13:25

So the earth is round in the moon

13:27

is round and the moon pulls on the

13:29

as in a build up a little bowels

13:31

of the is is it about in the

13:33

As Yeltsin water but in the land on

13:35

the whole of the Us yeah it is

13:37

about the by Microsoft and is in a

13:39

rotates around over of us and the moon

13:42

is trying to pull it back to the

13:44

moon is trying to move slowed any as

13:46

as one fact that's another factor is something

13:48

we going on with the core of the

13:50

earth and we don't understand it will be

13:52

so that know what we get magnetism and

13:54

in. Is another factor. The atmosphere.

13:56

We humans. Way. About

13:58

half a billion tons. The atmosphere is

14:00

five thousand times more than that. Oh,

14:03

so every genuine savory you get the is

14:06

slowing down by few milliseconds each day. Think

14:08

about South America, which confusingly has part of

14:10

it in North America has been as paternal

14:12

that is. So you're a South America right?

14:15

Feel the Andes running like a big sale

14:17

from the equator down the South Pole. and

14:19

if you have a high pressure system on

14:21

one side and low pressure on the other

14:24

or the other way round, yeah it will

14:26

affect rotations the it's and that happens. Every

14:28

genuine savory. Says it's a

14:30

budding. Also, we got the humans. So.

14:33

We humans in proportion to the was

14:35

years a like three cells on your

14:37

body out of the thirty seven trillion

14:39

that we have side effects to we

14:41

have directly is very small boss. So.

14:45

We're half a billion tons, But

14:47

the earth, naturally vi the rivers.

14:49

She's twenty billion tons of a

14:51

year and we have shifted. Seven.

14:54

Hundred and sixty billion tons of a year,

14:56

but causing global warming. By

14:59

mini cab dogs. I was in mills

15:01

Seven hundred and fifty million So billion

15:03

tons of ice every year. So so

15:06

those three sectors. And our and

15:08

atmosphere or combining to figure rotations the

15:10

Us believe very running the same taunts

15:12

went into the seeking for human here

15:14

of ten years while but that's a

15:16

but our carbon emissions are doing possibly

15:18

mass of carbon emissions A The good

15:20

news is that we can stop and

15:23

reverse global warming with the days technologies

15:25

dancing stopping us as allies put out

15:27

by big fossil fuel since about nineteen

15:29

ninety like big tobacco and big alcohol

15:31

doesn't person says business Yeah to them.

15:33

Days Eve got a question about one of your

15:36

pet peeves. Soda State are you have got

15:38

us? Yes, I have a pet peeve

15:40

about bad breath. I don't

15:42

know why, I just do. People bad

15:44

breast gets me sit. Article. What's

15:47

the best way to get? Married I was there and

15:49

I think maybe this stems from having a

15:51

dog out who I say some bad breath.

15:53

I've also humans of how became aware of

15:55

it we might have to arouse five years

15:57

old and she came to bed and said

15:59

daddy Daniel. Worry About followed

16:01

immediately by. I daddy. You

16:04

smell like a bomb. Wants I have a

16:06

solid is rewarded confirmation saw rolled over us

16:09

My wife do i smell like a bomb

16:11

as you will get is more like a

16:13

bomb A nigger means was in the concept

16:15

of bad breath in the world expert on

16:18

bad breath is no Rosenbergs who start of

16:20

the naughty naughty anybody two thousand and to

16:22

mention the article on bad breath in the

16:24

Scientific American and he sort of start off

16:27

the field and bad breath is overwhelmingly caused

16:29

by your mouth and he fought the since

16:31

nine to support This is a time you.

16:33

Knows you've got bad things up your nose

16:36

is a case all of a woman who

16:38

had served a little body part of her

16:40

nose or yeah says if he is am

16:43

tonsils yeah we've ever to net know the

16:45

news snake You put your hand for an

16:47

email to catch it and he says his

16:49

tiny spots about two millimeters in terms of

16:52

the consulate this is the stones and you

16:54

have with things like try me so I'm

16:56

on us where you smell like a fish

16:59

that overwhelmingly it's a bacteria in your mouth

17:01

but he can do about it is have

17:03

good dental. Hygiene, Brush your teeth and

17:05

your gums and use electric toothbrush. They're

17:07

monsters where you are so that way

17:10

you can a buy your new robot

17:12
