Skip the commercials support star talk on patriarch to listen to every episode, Commercial free, from the American Museum of Natural history in New York, city and beaming. All is based and start with and your host real addressed ice in your personal physicist, and with me Jack knife, Jack today its cosmic wearies? That's one of my favorite. Forms by about my luggage, Burma, by love by love it and we
in fact, educated. My mom is spreading and grave right method. So this is a consequence of a topic. We ve work solicited now, we have not yet what and when is the deep, deep space, deep thoughts. Questions? Where would you gotta give it in your deepen? Ok, a widow and about it, we did this one, yes with light, and I think I I I think I better by half a tone is a year just bear them here we go deep thoughts. D yeah. You got me already- see I gotta during Scotch Edgewater cigar. I got a smoky cigarette smoking or just fixed up right. I did it becomes like a deep boys and like somewhat huh,
requires fire, raspy, rasper, deep, so odd guy, if you put on the acts deep thought, scotch, doesn't give you the hearty hardihood asset. Pretty cool of its couples, who had just leave don't call me an old I've had too much and shrink alright, let's get the letter Deep thought could thought. Usually there isn't a right answer, so you just get a sort of play with it and see. Where takes you MA am So this is deeply questions only I, let's do it so lesson from our fan base this from our fan base and, as usual, we start with a patriotic patron, because their fans that pay us and nothing says Phantom was like all right?
but we're dead levels you can be under way pays rests with the lowest level. Five bucks, someone. Actually you can go to the two two dollars a month that we really want you to come in at five so that you can get the perks of getting. Videos are unable to get extra content and we revamp tat. We re doing. I remember watching the with one of them. I think do you. You come on the shop. Yes, that directive Why would you aren't start off? Yes, you come on the shell and you are a guest on this right and you get to ask all the questions. One, that's cool. You know where I would do. We say whether we actually era that's all right, not only by the way when there be the ultimate leg reborn. The open his last week, and I expect to see this- oh you can. Unfortunately, I so, let's go for a patriot I'm patron, and here is the question from Jonathan Wax
other than says or ask what boggles you're mine more than the thought of endless time or the thought of endless space, so it's impossible to truly contemplate. And was time because you spend the rest of your existence doing so. Well, here's to things bottle me: ok is a beautiful frontier of research going on in the field of neuroscience o interesting. So I have two questions related to that. The bottle my mind. Ok, right, these down. Can the human brain. Figure out the human mind, so grave is the human brain after creates, if it the human mind so good.
A switch from say, or do you need something outside of that right? It is greater smarter different, so they can come in and then understand that as its own test test kitchen. Not so Sagan his famously said the head that humans, are the universe, is way too understand itself the universe is understanding itself through human through humans. Without humans. There be no thoughts right. Did you do that? But, however, that elevates us higher than I am prepared to do so you thanks because who says we are the measure of what is intelligent in this universe. While we do, we have that are actually know that, and so that statement that Carl Sagan statement is kind of like a cosmic, logical Descartes. That's right, the universe, the Descartes cart. You
I think, therefore, I get anything right here right. It's like. We think. Therefore, you are o o o check every once in a while. We think there, were you are and as I think, therefore, I am there oh check that was beautiful. I thank MRS end. The show right now we're surpass, and I thank you for one that it's down from her, so I wonder whether There is a level of intelligence at their where we are today. What chimpanzees are to us as interesting? So oh, that's terrible? What whereby we all? I hope that when you go to chimpanzee and say and say tomorrow morning at eight thirty, let's go to Starbucks and have a cup of coffee. Nothing in their sentence makes any sense to a chimpanzee right,
ever? Will I'm pretty sure there's a Jim Jim start have hurt Pretty sure there is a tombstone somebody up of this today. Anything Starbucks figured, I answered, I wonder, is it gotta be selling chimps equality, somehow some ways that why does your hyper at the zoo that united me, you gotta get your comedies just like Jerry is George curious jars. Think That's ok women souls out, so I went up why I say that it is many times a written it. My will tell you to your face now. I good sort. This bout, one percent difference in DNA between humans and ships right, yet we like think of ourselves as highly highly superior intellectually to the chip right. Maybe the difference in our brain power is small, as that one percent indicates so that
pulling termites out of a man with a stick that was carefully chosen from branch write it up from her from it a bush. Maybe that is not very far from space. Rather, heavy looks like thing about it I know this sounds crazy. Think about maybe maybe look at those cute little humans in itself is that ok sooner watch the smartest chip that are studied in labs right. There are brought forth into chip societies right, you bring it forward and what do they do? The stack boxes to reach a bit it might put up an umbrella. They'll do some things. Gary have rudimentary silent. Are toddlers can do but these are the smartest chimps do it, but I toddlers do they said they were dogs
No I dont have about. I can. I could do this example for dogs. Whether changes is that the network, because they are closer to close even closer- I got you got to see what you do. Is you go ass if the smartest chip, because our tumblr only one percent difference in DNA between right. Let's go A one percent beyond us as scared, that's insane If we go one percent be honest in that same vector of intelligence. He had a travelling at the speed of light. Then they ve developed a light travel. Then the smartest human they'll role forward, but take we'll, take Stephen hawking and I say this human is slightly smarter than the rest, because he can do still physics calculations in his head right, like little Timmy over here who just came over alien preschool right. The toddler the toddler right
as you all you just composer cited, is an acute put it upon the refrigerator. Oh, you just arrived the principles of calculus eyes that money so if the smartest human does with their toddlers can do great their average people will have thoughts. It will have sentences that will rise above and beyond our most brilliant capacity to understand, and I stay awake at night wondering whether the universe has complexities in it that are out of reach. The Neuro Synopsis of the human brain wow? That's my ass so there's information out there that we just cannot conceive or partly, don't even know how to access the internet right about it to get an answer, we don't know the as yet another question to get a man to get an answer right in that they would nor could we have been told again. Oh I just can't could see can't you see what do you mean what ship
And say: go to chip and say what would it be altered, something as simple as navigating the stars to get some place, but I can't do that stars were navigate. Why? What's bishop, what rocket fuel? What none of that none of it? You can't even have that conversation right. So that's my point now think about it. All might be some type of Blake Science experiment by some alien kid. Now this that Europe, what we are all a simulation. Didn't you include the basement rather more data out of the house. She felt herself whether minecraft of some other bio remind granted it yes wow. Well, yeah the things get to peaceful and stable. They stir the pastor. Autopilot I want a politician wore a crazy person
don't they and their now is entertaining so, which is entertainment for this? the best video game. Wow aware that it will listen. That's a great answer to what bothers you're mine as a really isn't much Boggley mine, it upsets my mind yeah. I was what say it's very Sadly, are we not I'm mad, I'm leaving a while? here's my watch out lets you right go ahead because for humans, our knowledge is cumulative. So true, you don't have to invent calculus Somebody after that right, you have to use it right, learned and use it tonight, so I have a feeling that we are. Next generation that has stood a brilliant people contributing to our understanding of the universe, the adding a wrong to allow right, then we also climbed up there and then just get the next round.
What wrong? With that in mind, I think that the next evolutionary suffer human beings is that We will create an intelligence greater than our own. That's really the d, a scared, the hell out of here, yeah, because that intelligence will say we don't need you and you know what We'd have to say you're right, that's what happened in the matrix yeah virus on this earth. Mr Andersson, ice. Mr Andrews, and now he was smelling morphine others right That's right! You get your man if you, if you can go to their economy from the rise, my favorite movie is true. No even yes, he was talking about Morpheus. One item in the chair, yeah, it's the smell of! Do you know where you got you guys are really serious appeal for a computer to tell you stay in here,
hi I let's look through the electronic did so This is a reality. Gregg fifty six from Instagram and Alex Gregg says this: if the universe needs not make any sense to us, then what is the point of doing? Science is science, not in fact the discipline of trying to grasp what around us by the way, is this statement not equal to the old one which is God has his reason to make it that way. So just don't ask who was never that expression but that the short version of that is, God works and mysterious way. So true, when you can explain it can do I got the Lord works and mysterious will rise and if you can explain it using God than you do right. Oh God is blessed you, you bless, got
you have done, is a salami takes out accordingly, be God She had no one says that says that why don't we say that we should do that. Now I want to start saying you know what I think, God hates you well, the most hateful God in our culture is the one represented on assurance worms? That's so true acts of God acts of God right. It's only even very bad. Things are no one says flower. Bloomed in your garden, an act of God right now. It's not me took action house! That's homeless, illustrate ACT of God. Wow! Look at that this moment of God hates you bought to you by farmers and safer. That's right! That's what it's up up up up up up what they want and why is it not on your face? Why does argues that? God is our ok, that's enough! So we'll get somebody male now
anyone in I hate God, junk inanimate objects are all the soul is size, in fact, the discipline of trying to ground what is our round what he started? What was going quoting me ray. I said I opened my book, the astrophysical people in a hurry right with the quote. The universe is under no obligation to make sense to write. What that means. Is Europe five? national centres which rose out of the Serengeti Hooker, which help us not get eaten by lions right right, the very good at that do not have good. Contemplating infinity did good contemplating timescale much longer than your life expectancy. So true you, don't you can't into it billions of years. You can't intuit infinitesimal, do things that are hard for right there, things that may even be impossible for us. Can you picked
five dimensional q. Now I can, I know you cannot keep up your for dimensional cute, probably that neither the detractors clubs, yet that's like her. I can. I can actually, so that is the cause of Siena dry. I have do you really do get out, I was always membrane and way again today. The allow another up is another episode will be the episode higher dimensions sweet to holding. Tired and would have understood it like that? We did, we didn't already elemental, remember there and we can all. Did. I have my test erected by him. We can do it again. I took this from Santos, so what it means is, if you are going to deduce what is or is not in the universe, right, your senses or not the most reliable measure of whether its true Sancho the senses,
a restricted understanding of what is actually going on in the universe. Your eyes, you would never trade them for anything. Yet they only expose your your mind to very tiny, narrow strip of all the electromagnet energy is out there. You can see infrared, you can feel it as he can see ultraviolet. They can see that either. You can feel that and a delayed sense by getting sunburn reckon cancer tell you in that instance, it's about time delay, but you're going out. There's infrared ultraviolet Ex rig gamma rays, can't see any that, but the universe is talking to you in it, so you gonna say My senses give me everything there is in the universe and there where it makes sense note As long as we detect things that fall outside of our senses, it's a challenge for you to declare that what we say do and discover makes sense.
Very statement, makes sense means your senses can contemplate it right at your senses, have experience. If I let go of a ball and floats up, you say that doesn't make sense. Because your senses always told you like over boy drafts and in fact, the very statement. Gotta go not the present, the frozen version budget, let it go means drop. It. They mean the same thing, but that can Can we be true on earth with the force of gravity pointing down in space we in free orbit? You let go just watch these days right. There statement there. So, like my problems that say right dear, I must be a space because all my problems such as this drop it myself that old. There right still here and you let it go and exactly so. My point is the method which was signed give you a way to understand what is true without it being here engaged on whether your senses think it's true nice. So
until the site or access to truth weakens. Probe the universe, whereas got works, a mist. His ways, kind of ends that conversation, As I say, I developed a new Instrument that can see in ways humans cannot. Oh, my gosh opens entire world of investigation, entire branches of science and they have a right. We can take a break. Ok, I answer to all know deep and we are we going to deal with Africa exactly where we come back more cosmic web tv, Hey I've got no secret for you. When I consider singing all of the ads on this shell just one way to get out a hearing there go to patriarch
coms. Last starred talk and supporters at the five dollar level or higher to listen. The star talk ad free. You can download all current episodes into your favorite parkers player and ever hear another commercial on star talk ever again. You will definitely not have to hear me saying if you support us at patriarch doc arms last our talk, radio, I mean I'm just thinking I mean just saying. This is a start Yes, it is deep, deep, deep I think I know the difference when I think I think we hit the same note.
But I have more sort a cavity residence. This is just cavack. Will your bigger guided than I did it jack here we go. This is from probably asleep. The person, the name of the person- ok, like your mama, didn't like you how long? Think the human race wisely survive wow. I mean there's precedent for that rivals. You can look at what is the average life expectancy of mammals, mammal species and last I check It was around two million years, something like that And so we built around a long way to go a long way to go. We ve been around your cup a hundred thousand years and are in our current anatomical form, Romagna form and so that means we have a long way to go, but this presumes at the species is not smart enough to kill itself well in. It over that was nice. Now you guys,
yet we have invented multiple ways to kill myself and I don't think the elephants did or in a nobody else. Did this out and the mice now than I, one themselves right humans, guess maybe maybe cockroaches embedded human beings Why? Because, when everything's gone, they're gonna be the only one left, Not then they will have to invest in the first place, we're gonna reasoning are using here they were. Everything else gone, so they need us. Build a structure that they then read. Internet move, and I don't mind Yet that makes that makes perfect sense. Young we button. So I think what is We asking is in your estimation, from your siege of I give. How long do you think we will? Last I give us twenty year That's funny now I'd. I think we're good.
This why many people want to become a two planet species terror for more send some humans. There, some bad happens on earth. You still have humans somewhere else loud, has not encouraging at all not for half the people who I know you know and if an asteroid comes if a killer virus. If a I goes gives out a hand, or I understand, seeding something with a remnant for survival of the species. Dad's extraneous I mean that's, that's something there outside of our own destruction. You know that, even though we could stop now starting from hitting us. If we point out how we did it, we were no nobody doing little or no end. If we ve got the resources where we could start even that from ass, what it with these ample, you give it up. So what I mean to stop the gas ruin of what it so so I'm saying, as you know, will we ever get to a place where these, as the Buddhist monk call it the so called monkey brain.
That causes us to do so. Much destructive, work to each other and to the planet. Will we ever get to a place where we overcome that or were able to train those who come behind us to overcome that now it does happen in some people. I get it. I first I've never heard a buddhist monk. Say defrayed monkey bring about heard that this is a thank this ok, fine, I, but that is a fair return, more monasteries and you feel a monkey brain today. I deserve it. I've heard of reptilian brain, but not monkey bring yes, okay, so so the repealing this reference, something primal that goes on within you, So if we follow the reasoning by Steven Pinker and his book, the better angels of our nature, he studied did likelihood
you dying before maturity or dying before adulthood, we're just dying from at the hands of another human, from early days of tribal warfare to modern days of state sanctioned globally. And what we found is that the likelihood of you dying in that way has been dropping ever since probable warfare you could? You would kill, maybe a third or half of the other tribes Or the entire tribe, and then you win and you get their land. It doesn't happen today the state surrenders before that happens, true saving the lives of the rest of the population. If you look at it, I did is just recently. If you look at what countries had the greatest per cent of their population die in the second world war? I thought it was a Belarus. One of them is very high. Like a third, I forgot the exact numbers but their high
but did not have any keep going down and you get to do even combat, Germany wants. There were heavily bond Germany, Japan, a free, sure the total population that is not how it used to end in trouble warfare, so Now consider the tea in so doing Second, world war between one thousand nine hundred and thirty nine and one thousand nine hundred and forty five one thousand yuan, killed by other humans per hour for every hour from nineteen thirty nineteen eighteen, forty five, Why is that going on today? No no, no arrests were really slip. A nurse really pick a bribe Henry just a week ago. So the point is often that Error is called the greatest generation right because they fought you no evil. For It is in this sort of thing about my father. In a segregated army, so he's not thinking that
the greatest generation. He has other our perspectives on that period, the second greatest general My point is Is the greatest generation the one where the fuse fraction of everyone dies out of hate? I have a lot to hate, but if the number of people who die from it is lower than ever before, right then this arc that you are hinting at that may be. A next generation learns from the previous one. Maybe that's gonna work with all their turbulence in turmoil actually haven't been at war with each other for seventy years way. Is there another seventy year period history of Europe, where nobody. Frightened anybody not open not of twitter hesitating signal. Would you say that Imagine if twitter existed that there back then all by MRS them, with that the war wouldn't stop. Everybody was dead. One thing I would like to see: what is that I'd? I surrender the tweet
I've gone out every life? I'd, take it back. Let's keep fired, let's keep bite it. I don't care. I hate you wore I forever. So maybe we are getting kind were kinder, gentler time still needs to bear that out on a level that would please everyone, but I still worry. That this primal brain will always segregate us all by some arbitrary factor and they by justified, doing harm to other groups. An interesting that I think you know who's a comedian? Was it the Franklin, a giant these guys from seven Adele in ITALY today, in the day he was talking about you hate? Who in the world right again It has read the papers and what, in Northern Ireland, the Protestants, Catholics are fighting each other both why
you know, I don't have a black surrounding us through the right it why people divide themselves up in that right who christian communities killing each other yeah, the both white and both Christian and a boy s overflow you brought itself is, however, every people can kill each other. For those reasons, it's almost no hope in this world. So here I don't know Yes, I'm have a good answer. It was a pretty good answer. The answer is: we're not gonna make it. I like to think you go thousands of years into the future and possibly out live the sun. I dab great bright stopped star hopping to other planetary systems met. You know, I'm just gonna stay that way. It's gonna end because I won't be here soon. A great. Maybe the has been said that the first person we'll never die is now alive. What that's it How do I know just there? So they get they get some new thing that makes you live in extra fifty years. So are you fifty, instead of a hundred and then
somewhere in their lives, Another thing we get our you live another two hundred years, two hundred fifty votes at three hundred fifty now you'll have five hundred, Now you go to thousand you can the five thousand years now so as we progress in our understanding of what ages you. If we can reverse that were prevented from ever advancing the person there's someone alive today who will benefit from it. Then Pretty cool, I like it, so if that happens, you better find another planet that this is true. You that's the premise of the so called altered carbon where people actually take their consciousness and put it into what they call asleep which is the body said. I think I voice over the opening sequence. Oh my god, I think we have the cars is whether you told me that I told you I don't ever with the pilot or the other shows, but I didn't bite, but I let my voice to the. Nigh ass. Well, Well, let's go to Joey twenty four Joey Junior twenty four. He says this personal question.
Based on all your experiences and knowledge, thus far below for me over personal for you, ok, that nobody asked if he says, base on all of your experiences and knowledge. Thus far, what do you think the meaning of our human distance? Is he just ask you? What is the meaning of life accords to fail to grasp Thyssen. Ok, so I in my next book yeah I don't want. You never hear me plug my staff as they hit the meaning of life right now. What are you getting a chain of reckless letters from an astrophysicist. I you know what that yes, first one I've had with people who had similar eggs, yes about their existence. Life. Not just the book is not about that,
no don't worry that there are different kinds of letters. You all kinds of letters ass, but a very recurring theme is that people want to know the meaning of. If in their significance of their life in this world, and some come from religious angles, summer secular, but everybody's got this burning issue. Yes, so here's how I have dealt with in other do in other ways: ok, but he's our ideal with I'm interested in many people are each of the meaning of life as though it's behind a tree right raw right by noses in it. Or badly exaggerated paperclip ever drugs will not like. I would like our underwear, Georgia. You know that you're, where you go, look for sale since the Algeria Bedrock that Iraq Georgia junk whereby down near the kitchen somewhere bright, so if
we're looking for meaning you may never find it. So instead. Recognise that you have the power to manufacture you created within yourself. That's what I do my meaning. Life is derived by several simple principles. Have I lessened the sufferings of others today? That brings meaning to me, because that means the world is a little better off, because I was in it today if, after your day is over the world is worse off. You have, sir meaning you must at and everyday. Somebody is like that. Mother we'll go so so lessons suffering of others, some way right
made redirect your whole life mind body and soul, but if you can help someone across the street help. Aging person? Do you don't make a look but child lass? Just put a little bit of joy in the world to lessen the suffering I also try to learn something every day I now I'd like being a perpetual student, like most people hated being students. This saddens me Schools finished and body. Do you run down the steps? School is our ever re who out for the summer that attitude, shooting that song as though you don't wanna be in school, and what's your only job in school, to learn to learn and somehow that's a chore. I don't blame you for real in that way. I blame you as a single system for not instilling within us. No curiosity knowing, you will spend more years of your life, not in school, that in school and so
Have curiosity, you can be a lifelong learning, and so I want to lessen the sufferings of others. And make sure I learned something more about the world today then I did yesterday nice and who is to say whether that extra incriminate learning can help me be better at Lessing this, lessening the sufferings of others So that is how I make meaning in life and, as a result, I own thousands of books. Thousands and I read a little bit inaudible stash near my bed and recycle them out. And every try to have its harder now. Can I get recognized but try to help people every day, total stranger, that's nice here, so you can make meaning for yourself look for. Could you may never find it aren't. You know under say as a philosophy. That is that's. That's! That's that's admirable that nothing in the book. I wrote that about nice, excellent ex. Thank you,
We want an adequately have one more question. We have limited in this segment guy here we go, men Zan may men's in their ok, there you go. Destiny. People ok on Instagram said, as I keep hearing the phrase, the vacuum of space. Yes, how exactly is it very nice as a really good question. Whenever The answer we take a break when we come, back from hour, break more from cosmic queries
I would like to give a patriotic shut out of the following patriarch patrons Roy, they'll, Percival, Jose Clark and Doktor. Janet L walks thanks? So much guys were helping us made this little trip through the cosmos and if you would like to support us on patriarch gotta to dot com to start. We're back, I'm starting cosmic Weren T petition jock, yes
angled a question before that break? One was yet a big tease from Ninja Jan Meet, whatever no Zalm Mete out. Oh no said I keep hearing them. As the vacuum of space? How exactly is it a vacuum? Right, ok, when I was a kid, a vacuum was a physical objects alone. I heard physicists the bigger the vacuum space. I just met ITALY's Hoover's rank in the sky, right. I do know that vacuum was a thing was it was an empty, was a concept did you make a machine that duplicates that thing? I just didn't know that. So I learned ok, so a vacuum is where there is basically no air. You can have objects there but when we think of a vacuum is not a place where there isn't, anything is a place where there is no air molecules moving typically, generally. You can have some and we would still classified as a vacuum. As you have said, seems like a regular overcome, worried, perfect vacuum away. They know it.
If there's an object, any take away all the earmarking. The object out gases molecules in their surface of that object, and they start coming two thousand then she hated it sends out more does very hard to make a perfect vacuum very hard. So is an old saying, no You're abhor abhor, is a fact that these are people who ever been to space The universe is a vacuum nature vacuum nice was a trumpet and they're, not nerve, major, let their value so preferably Trumpery vacuum drop from people tromp ran back you. We got the best shock, There's another there's another saying: there's no such thing as gravity earth sucks. So the point is when is a source of gravity or the air wants to go to that source of gravity, and it leaves a vacuum everywhere else
so a vacuum is simply where there's no heir, and it's not anything deep. The odd thing in the universe is that you have places were airport where gas molecule collect, ok, that those are the unusual places in the universe and the call stars and gashes planet and the atmosphere is a rocky planets nigh, so they have a vacuum such are: gonna put but enclosure. On his back in question tat, this is the second
a third book ever published all cattle just visiting this planet, all right and it's a collection of back. I q and I had a column a pet with appending berwin people have fun really playful questions asked collected this like decades old, but there's some time was content in here. Somebody asked about the backing legal help. Please Miller on you can't read out, alas, ok area, the best vacuum you will find anywhere, but this thirty years ago the best vacuum you'll find anywhere according to four out of five vacuum. Retailers and five out of five astronomers is the void of intergalactic space. But we can then ask these intergalactic space, nothing
still contains space. If you feel obliged to call intergalactic space nothing, then you must invent a word to refer to the region out. Out of the universe in this location, where we presume there to be no space. There can be no nothing wow, let's call it were left with no choice, nothing nothing, not place where there is not even nothing. Is there nothing, nothing wow I like that. In the same the truck. He wants a more vacuum talk, of course, I've gotta, I feel, like you, just showed up at my door and dump some dirt on my comp, more vacuum. Ok, vacuums in death, my black hole right thing about this- is so in a chapter on being dense.
Ok, good business hunt? I know a great deal about. The range of measured densities within our universe, staggeringly large, we find the highest densities within pulsars when new charges so tightly packed that one thing in what way about as much as a herd of fifty million of fifty million and then a rabbit disappears into thin air and imagination. Nobody tells Is that thin air already contains over Tens Gillian Adams per Cubic metre well sinner dinner, the best laboratory vacuum changes can pump down to as few as ten billion Adam, we're cubic me best backing as the best value Vienna Cubic Metre. Ten billion air molecules are still walking around Knocker interplanetary space gets done
to about ten million Adams per cubic metre while interested or is as low as a half a million Adams procurement law that has now that was very there is no damage, five hundred thousand atoms, the the award for nothing. This, however, must be given to the space between the galaxies intergalactic space, where it is difficult to find more than a few items for every ten cubic metres. Wow that wind That's that's almost that's almost nothing! Nothing! That's almost! Nothing! Nothing! We're going to a deep lightning what only a minutes left. Ok, let's go. Ok here we go. This is John Saldana says right now
What should be the priority in the field of space exploration, searching for life, searching for potential threats of another kind of search, or is there just no hurry at this matter at all? Greetings from he call may go. Thank you. So what is it is it? Is it it is. Are we looking for lawyers, because my opinion, I got an exploration I gotta go. I got an opinion. I got it. I want to do it all. Why not do it all want and all of the above all the above II, because the moment you do this and not that right, they say why do they not that occurs? We voted that way, but maybe you don't know why you should do that when you want to do that. Somebody wanted you that here's, what you do you don't build a row just from New York to allay you build roads everywhere, so that I want to visit that forest. I want to visit this. This discipline rocky monument I want to do things that are not try by you, I'm going to see them
it is ball of yarn ever exactly great right. So what you do is you make a spaceship that is, modular, strap. On different combinations of Rockets Ray I this right. This commission get you to an asteroid to mine, This get you of the moon. Diskette should a Mars. So you know scribe What it is you gonna do next in space you let the creativity and imagination of all those who have ever looked up said. This is what I want to do any say here you go to from I'll. Be there sure from I'll see you're on your way, and I put that on a credit card yeah that's right, get Adam in the airwaves once you know this from Instagram, how far behind you think astronomy would be if the earth didn't have the moon, Ok, so it's not! How far behind we'd be right, it's how far advanced we be
Why salami split this out, I tweeted during space, weak the fiftieth anniversary of the landing. There is a saying that common in the space circles at if guy I wanted us to explore space. He would have given us a move right. So I guess I'd better, go saying yes, but that exploration is not astrophysicist exploration, that one is people going into space right. We ve got you got a rocket to go where you ever moon to visit it but astral physics stars, the naked? I can see at night. A more than I can count, nor is it about three or four thousand oh really, who unaided binoculars it hundred times, telescope the billions, but I'd three four thousand are ok.
What is a full moon out? Three hundred start yet right, the moon wreaked havoc and our ability to see the rest the universe so are. Observing schedules with huge telescopes are split, dark time or bright time? If you look at Evian bright time, observations it. The moon is up and you can only look a bright objects in the night sky, while the deep universe, only comes to us when the moon is not up, so the moon is basically a pain in the ass, the star blocker. Why? Yes starboard! Look at that. What did it so strongly would be probably half again more advanced, because we would have but these greatest telescopes in the world, looking at the night sky, twice as often right in the dark as part of the night sky, they yoga, our next other damn good answer. Okay, this is
ever sit a poor. I dont know what his who cares, what I'm sorry, whoever that is care. Let me tell you something. Last time he's gonna be asking you a question. I will you know what your name is nominal call. You, George Rights, George, wants to move is the shape of space itself as a good question? Wealths race can be curbed, in the presence of matter or energy, as prescribed by Einstein's has generally reader leverage relativity and there's the off repeated, saying matter too. Space. How to occur. Space tells matter how to me nah. So space has curvature in the presence of matter and energy, the curves in towards it, with the ultimate expression of that a black hole where occurs in and it never curve Why, if you want to ask what is the shape of or space that's like saying, was the shape of the universe, the observable yours, it's basically a perfect sphere.
Well. Why? Because it your horizon right, it's a private sphere. The way when you see your horizon is up Circling that's right, the same distance in every direction, right, if you, if you're just out and there's not a brighter, and so what is the three dimensional version of a circle, a spear s we're so in space you can see here horizon in every direction which arouses all at once. It is at this week. It makes think what the centre of atmosphere, but that's, not from you, thinking, you're the ownership rights. Because you're in the centre of your horizon at its next dies, gray by a good laugh right. We're here we go for this is a genuine who says if we look if, weren't you look in all directions: billions of light years away will You see younger universe in all directions, enveloping our bigger one. Now. Have to rephrase that cause. If you look out, you see things not as they are. They were right. So you are low
at a younger and younger and younger universe. That's all oh point of cosmology. It allowed the fact that it takes light time to reach us, allows us to see what the universe was doing in the past right. If might travel, it is speed, you see the whole universe as it is now we know ever of what it was once doing, but because it takes like trying to move you look, out, you see a younger and younger numbering of the universe until you see the big bang itself, and that is fourteen billion my ear. There's time away from us in every direction. Ok for twenty two years ago, right, ok, an if you calculate that distance, through that changing time it fourteen timber. My ears to that arising? Ok, so But without horizon is much farther away today right because Europe has been expanding. But you'll, see as it is today.
You see that was right. So I want to say of today As I say, Unless you do a quick right, I got a fire when, as you could do really, I don't know how quick I can answer. Ok, I'm gonna give you want here we go. This is this? Is my son? Did ok, I don't care what this is Try, Jack, ok, my son, by frantic. But something ok forget it. You didn't give here's the name right. There was. That said, he said. But something, the right, that's what it is, but something scene. I just want to get away what, if other matter,
that we see in the universe is just three dimensional part of some four dimensional matter and the dark gravity is just the amity from the forty part that we cannot say I love it. We are so blind to a higher dimension right. It could be that all the mysteries in our three dimensions plus time. Are completely solve by looking at this. From a higher and higher demands it bright right, just if you'd lived in just a flat surface, that's going on! You had no idea right and we say, but can't you just see just woke up what is up. What is that graphite they making making it making. Creating start right. Unemployment outlets arise from last year is exaggerated. Just shows utter a right right, so I love it. Does universe. I wanted to be We figure out how to see higher dimensions, whom we figured everything out of it the audit Chuck we gotta run. I write that down. I enjoyed that. We share cosmic worries.
