I chose to listen to this video for my bedtime story. It was great! I had a dream of our world and the universe that was truly amazing. Thank you for sharing 🙏✨
@Inflix I dreamed about flying over the earth and I could see many stars, very bright galaxies. I felt like it would be good if we can travel through time to everywhere we want. Though, I must pay more attention to listen to the book, and learn much more from what the Professor had written and told us. (And I must confess that I could understand the whole thing, but I will try.)

If time were not a moving thing And I could make it stay This hour of love we share Would always be There'd be no coming day To shine a morning light And make us realize our night is over
I have always been fascinated by fiction and poems of love. I have almost been driven by this ideology of love. (almost). If we stop the time. There will be no chaos, when there is no chaos there will be no possibility. Only perfection will be. Perfection is a certainty. It never moves so it never falls, It never asks so it never fails. Perfection is not our nature. Perfection is an imperfection of humanity. We are imperfections of perfection so we exist. And imperfection is what makes us perfect to be us. We were born from probability so we take a risk. We living in the possibility of time so there is a risk of the end. Never believe when someone says it is always. if it never ends there would be no wisdom in it. Because night ends, it makes those moments so precious. We never love someone for satisfaction. We love someone because they are perfect to love as who they are. ( Don't make it stay, let it expand)
How I wish I was clever enough to understood this....I know what the words mean!!!!, but I can't get my head round it and the idea that space doesn't end blows my mind ...loved listening to this, thanks
do you love your mother ? or your child ? ok, now for all of those who need or demand a "proof" of a thing in order for it to exist ; prove that you love them. as you will find it impossible to prove it to me, does that conclude that your "love" does not exist ? i hear people say " prove there is a GOD" & if you can't, He does not exist. imho, these people are using a narrow way of thinking... 🤔
Have I already written a comment saying that every audiobook in the history of audiobooks should be read by this narrator. He has such an incredible voice and reads so well genuinely bringing the text to life
R.I.P. when ever and where ever in spacetime you are? Happy Hawkings 80th birthday to all mankind in this spacetime. May all good things come to all of us.
What I’m curious about is that if laws of physics don’t apply within a singularity, then that could mean our laws of physics are unique to out specific universe and there could be other universes with alternative laws of physics. Maybe the atom looks and works completely differently some where else.
3:05 Aristotle was born around 384 BC in the ancient Greek kingdom of Macedonia where his father was the royal doctor. He grew up to be arguably the most influential philosopher ever, with modest nicknames like "the master" and simply "the philophe". His first big job was tutoring Alexander the Great, who soon after, went out and conquered the known world.
Aristotle in his book on The Heavens was able to put two forward good arguments for believing that the Earth was a round ball rather than a flat plate. First he realized that eclipses of the Moon were caused by Earth coming beetwen the Sun and the Moon. The Earth′s shadow on the Moon was spherical. If the Earth had been a flat disc the shadow would have been elongated aud elliptical unless the eclipse alwaus occureed at a time when the Sun was directle above the center of the disk. Second, the greeks knew from their travels that the Pole Star appeared lower in the sky when viewed in the South than it did more northerly regions. From the difference in the apparent positions on the Pole Star in Egipt at Greece Aristotle even quoted en estimate that the distance around the Earth was 400 000 stadia. It is not know exactly what length a stadium was but it may have been about 200 yards this would make Aristotle′s estimate about twice the currently accepted figure. The greeks even had a third argument that the Earth must be round for why else does one first see the sails of a ship coming over horizon and only later see the hull. Aristotle thought that the Eart was stationary and that the Sun the Moon and the planets and the stars moved in circular orbit about the Earth. He belived his because he felt for mystical reason that the Earth was the center of the Universe and then circuler motions was the most perfect. 4:49
We seem to be talking about the universe as if there is only one. I love Michael Yorks voice, so soothing. Thanks God we had Stephen Hawking on this small planet. Thank you for this presentation.
@Oggy Oggy my mother is dead Oggy, who cares what she thought, she was entitled to have her beliefs. I have no urge to debate with you, got other stuff to do. May your sunny day be a joy.
@marjorie goodwin Well you call something a god but what are its characteristics? For someone to call electricity a god is utter nonsense. It’s a beautiful sunny day here.
@marjorie goodwin Yeah, that word is loaded. I suspect you know nothing of the characteristics of this cause so to call it a god tends to bring a whole lot of baggage.
@Oggy Oggy Everyone has different perception of God. My God is not a religious being. For my mother, God was electricity, which seemed reasonable from her point of view. From my point of view, God is the first source and center of the Universe of Universes. I am not churchy, nor am I Christian. I actually am frustrated with people using the name in order to lord control over others. Perhaps mentioning God was a bad decision there where you read it, because it brings different things to all different minds. I have never had a filter, according to my elder sisters, so I type whatever comes to my mind, but I promise in no way do I wish to control anybody but myself, and that is hard enough work. Thank you for your very polite comment. You made me stop and think.
I listen to these to get back to sleep I am also very lucky to be a lucid dreamer so last night around 2 ish I put this on. When I was a young man I was a cobblestone paver and I was dreaming that I was back on the job paving a new sub division and all the differy contractors were talking Physics believe me in those days we definitely were not talking about physics 😃😂 more like boobs etc lol
@Joe Angel By breaking it down into its simplist possible components and explaining it as clearly as possible while retaining the full value of the explanation. I'm not saying I understand all this 100% lol I'm saying Stephen Hawking did an amazing job of making this knowledge understandable to everyday people.
I'm not a physicist nor do I play one on TV, but I have a feeling that the universe is not random but chaos dynamical. It is determinate but not predictable. That fits with quantum dynamics. I think that when we have a quantum description uniting gravity with the other forces, we'll be on our way to a quantum mechanical function for the universe and we'll see that as the function cycles through all the possible values, one or more of them will produce a probability of 1 or existence of a universe that supports life that can achieve what we have, at least. It would mean that we are living in one of several possible universes, which may or may not coexist, but we can't know about them if conservation of information is true. It's not the anthropic principle, it admits that some of the values in this function don't produce "us" and some work out without creating a universe at all.

a positive pressure exerted by the vacuum energy of space-time predicts; -the accelerating universe -gravitational lensing such as seen in the bullet cluster, where a region of less, higher density matter will warp space-time more than a region with more, lesser density matter. -Matter in the outer regions of galaxies / clusters, should be moving faster than we predict -Matter in the center region of galaxies / clusters should have added relativistic mass due to the additional vacuum pressure, increasing its escape velocity, allowing the stars in outer regions of the galaxies / clusters to travel faster than we predict possible without flying out of orbit -we should measure there to be more mass than we can see But this halo effect and extra mass being measures is explained by a positive pressure exerted by the vacuum energy of space-time. Dark matter is a fictitious force, nothing more than the effect or dark energy on barionic matter(regular matter)
0:000:030:450:581:03 The Theory of Everything the origin and fate of the Universe by Stephen W Hawking read by Michael York. Introduction. In this series of lectures I shall try to give an outline of what we think is the history of the Universe from the Big Bang to Black Holes. In the first lecture I shall briefly review past ideas about the Universe and how we go to our present picture one might call this the history of history of the Universe. In the second lecture I shall describe how both Newton′s and Einstein′s theories of gravity led to the conclusion that the Universe not be static. It had to be either expanding or contracting this in turn implied that there must have been a time between 10 and 20 billion years ago when the density of the Universe was infinite this is called the Big Bang. It would have been begining of the Universe.
1:08 1:33 In the third lecture I shall talk about black holes these are formed when a massive star or an even larger body collapses in on itself under theory of gravitational pull according to Einstein's general theory of relativity anyone foolish enought to fall into a black hole will be lost forever they will not be able to come out of black hole again instead history as far as they are concerned will come to a sticky 1:37
@Alastair Staunton Yes. "I commonly drop when it's dark" would be saying that gravity is affected by light and the joke punchline doesn't match the setup at all. 6 months, 14 replies, 241 thumbs up later and no one else commented on that.
Have you seen this? There is only one theory of everything that actually includes everything! There is now convincing evidence that the universe is a living organism! The questions of what the universe is, where it came from, what it evolves towards, and how it relates to human existence-are conclusively answered in terms of morphology as they begin to arise from Plato’s forms and Sheldrake’s work on morphogenetics, but mostly by genetics itself.
Nono, I mean with the computer voice. It'd be impressive to say the least, but it'd be more entertaining (to me at least) because it'd be really funny.
There is past present and future or why time goes forward and not backwards because apart from Hawking’s explanation of CPT, I would venture to say that it would be because we are sentient intelligent beings that happen to exist. We have been made possible by what I would call a Delta or a difference. A Delta T, Delta P, Delta D and so on even a Delta Emotion. The intelligent being collapses the wave function in a Quantum Theory fashion and fixes the point, makes a point real to himself (and others that share the same equipment as he has that discern a reality). When the intelligent being realizes a point (having collapsed the wave function that represents the point or object) and examines it, he then may wonder, where was this object from, what is it made of, what happens if I drop it, etc. Where did the universe that we see come from? And then the Delta takes over and creates time each time that the intelligent being explores. He could not explore and he could not have existed if there was no Delta i.e., Change. And each time he explores he collapses more and more of the wave function around him experiencing a world and senses passing of time.Entropy in a sense is a quality of time. If we conjure a glass of water (by defining, by collapsing the wave function) then the logical thing to ask yourself is “what if I drop this glass from the table?” So the concept of entropy is then defined. But is it real? Only to the intelligent cloud that we are. If we (ourselves) did not collapse as a wave function we would be a swirl of forces combining now, dissociating after, recombining in a different combination or mixture later etc. Our existence is a brief flash but the deltas in our brief existence we choose to expand, think about, write about, dig deep into the rabbit hole about, create a Hubble telescope about, be Hawking about.
I think that the most logical explanation is that: The expansion of the universe, although increasing for now, will eventually slow to zero, at t=P/2 (where P=period of the cycle), at which point it will collapse back into a singularity at t=P, a singularity that has EXACTLY the same characteristics as the original singularity. Once the singularity state (where all things are equal) is reached, it expands once again and the *same* galaxies are produced and the *same* suns are produced and the *same* planets are produced and the exact *same* lifeforms are produced and the exact *same* Humans are produced and the *same* websites are produced and the *same* Humans are reading this post. The implications of this are that everyone reading this now has (unknowingly) read this post many times before, and will read this post again, many 100s of billions of years apart. This theory fits nicely with the concept of the wave/particle duality because, in this case the SINGULARITY is the PARTICLE, and the RECURRING EXPANSION/COLLAPSE of the universe is the WAVE. Keep in mind that a WAVE by definition, has a cyclic nature defined by a period and has NO beginning nor end. Much like TIME, it continues forever.
Interesting thoughts but I have to disagree, but don't where to start (expansion/wavev function) ect as I'm tired. This was a great listen though 🌟🌡🌀⭐️🪐☀️
I would have been laughing so hard if this had been read by the author. Can you imagine the book being read by the robot voice of Stephen Hawking? That would be amazing.

@AMIT KUMAR I am of Indian heritage and a knight Templar...I have your knowledge checked many times over.. Seek God the Supreme master. WE ALL KNOW THIS FROM OUR ANCESTRY, MY FALLEN AND LOST BROTHER. CHRIST JESUS IS THE MYSTERY GOD, REVEALED TO US ALL IN HIS GRACE. FATHER EARTH IS THE ONE, OUR PEOPLE HAVE ALWAYS WORSHIPED, REVEALED TO US BY THE SPIRIT OF OUR FATHER'S, AS OUR LEGIONED HAS REVEALED. TO THE GREAT SPIRIT WE SUBMITT..
So, I mean, Stephen had several physical disabilities and speech difficulty and motor skill problems, he definitely couldn’t have dictated or typed or written this book.
This is NOT the audiobook to listen to when driving the car: unless you _actually_ want to plant your car upside down in a field, then be woken up to the sound of sirens and people shouting _''try not to move, we'll get you out as soon as we can''_
43:46 science would progress faster if we focus on scientific facts and evidence, rather than antagonizing people of faith. I mean no amount of evidence will make me stop believing in a creator, for me it's all about the overarching implications. Let say Hittler came to me with scientific evidence proving that he was correct, I wouldn't buy it at all no matter how much sense it made.
Who is to say that we won’t also be just a hash mark on a timeline of previously incorrect conceptions of, well, many things, including our place in the universe as we think we understand it today.
Hawking shat all over his own legacy when he employed circular reasoning to explain the origin of the universe: “The universe willed itself into existence.” 🙄

the goal of science is to predict events)
Gravity may be the limiting factor to developing more theories.
Why does the universe exist anyway? Did God create it? And who created God?
Wow! Thanks!
Pin this please
@Tyy Bankkson 🥰
Thank youuu
I chose to listen to this video for my bedtime story. It was great! I had a dream of our world and the universe that was truly amazing. Thank you for sharing 🙏✨
@Inflix I dreamed about flying over the earth and I could see many stars, very bright galaxies. I felt like it would be good if we can travel through time to everywhere we want. Though, I must pay more attention to listen to the book, and learn much more from what the Professor had written and told us. (And I must confess that I could understand the whole thing, but I will try.)
I'm sorry I feel the need to reply with my opinion, but no, you didn't have a dream of the earth and universe that night.🙃
Interesting book 📖
ALSO- Falling asleep to this reader is blissful 💕
Yes, I love Michael York’s voice too.
I agree
Thank you for reading and sharing. The closing line gave me chills as a reader, I am gaining more listening.
Thank you again.
great reader.. great voice , and perfect pronunciation... thank you.
Michael York is great in his reading of this book
But I wish it was done with Hawking's voice box
It’s Michael York. He was a Broadway actor and was in the movie Logan’s Run back in 1973. That movie was excellent.
Wanted to read this since a long time but finally remembered that there are amazing people who made it accessible here. ❤️
That closing line sent shivers down my spine.
Happy to see a Kenyan here🙏🏽
Indeed
Same, it's just such a resonant truth. It's always interesting to see the philosophical side of great geniuses.

How I wish I was clever enough to understood this....I know what the words mean!!!!, but I can't get my head round it and the idea that space doesn't end blows my mind ...loved listening to this, thanks
P up pop
do you love your mother ? or your child ? ok, now for all of those who need or demand a "proof" of a thing in order for it to exist ; prove that you love them. as you will find it impossible to prove it to me, does that conclude that your "love" does not exist ? i hear people say " prove there is a GOD" & if you can't, He does not exist. imho, these people are using a narrow way of thinking... 🤔
@Chase Lesser 😀... So frustrating isn't it 😃. X
Same here. I’m like:
“Whoow, that’s interesting, but what does it mean”.
There totally aliens among us humans.
Amazing. I was writing my homework while listening to this, very interesting.
@Josh Johnston same here. I can only do other mindless activities while listening
Impressive. I find it hard to take it all in if I’m focused on another intellectual activity.
Have I already written a comment saying that every audiobook in the history of audiobooks should be read by this narrator. He has such an incredible voice and reads so well genuinely bringing the text to life
@Mathew Winney haha it's Basil!
Michael York reads this book.
(He's a well known actor. Goolge his biography)
R.I.P. when ever and where ever in spacetime you are? Happy Hawkings 80th birthday to all mankind in this spacetime. May all good things come to all of us.
Michael York has such a great voice for audio books❤️
What I’m curious about is that if laws of physics don’t apply within a singularity, then that could mean our laws of physics are unique to out specific universe and there could be other universes with alternative laws of physics. Maybe the atom looks and works completely differently some where else.
That's what it may imply.
"Moral laws"? I think not.
Good observation indeed
@Waldi Tu ohh right.. that’s random lol in the grand scheme of the question
@Jon moral laws
I respect this man so much his voice and his potential for speaking is so good , love you sir
@I'm Going Supersonic 😧😳
He has been charged with a certain crime. Against youth actually.
I will have to add this book to my bookshelf just for reference purposes...great book, great reading
I will to look smart🤣
Amazing! Had to rewind many times to fully grasp what's being said. Smoke a joint, close your eyes, beautifull. Love it 💙
Profoundly fascinating book read by a man with an incredible voice
Luffy🤝
What would have been some real gangster ass shit would have been for hawking to read it.
3:05 Aristotle was born around 384 BC in the ancient Greek kingdom of Macedonia where his father was the royal doctor. He grew up to be arguably the most influential philosopher ever, with modest nicknames like "the master" and simply "the philophe". His first big job was tutoring Alexander the Great, who soon after, went out and conquered the known world.
It's all the centre, didn't you get it?
@Flag report quite literally!
🎼 Same as it ever was...
Same as it ever was...
Same as it ever was
Time isn't holding up
Time is an asterisk
It _is_ the center of the universe. Unless aliens show up.
Aristotle in his book on The Heavens was able to put two forward good arguments for believing that the Earth was a round ball rather than a flat plate.
First he realized that eclipses of the Moon were caused by Earth coming beetwen the Sun and the Moon.
The Earth′s shadow on the Moon was spherical. If the Earth had been a flat disc the shadow would have been elongated aud elliptical unless the eclipse alwaus occureed at a time when the Sun was directle above the center of the disk.
Second, the greeks knew from their travels that the Pole Star appeared lower in the sky when viewed in the South than it did more northerly regions. From the difference in the apparent positions on the Pole Star in Egipt at Greece Aristotle even quoted en estimate that the distance around the Earth was 400 000 stadia. It is not know exactly what length a stadium was but it may have been about 200 yards this would make Aristotle′s estimate about twice the currently accepted figure.
The greeks even had a third argument that the Earth must be round for why else does one first see the sails of a ship coming over horizon and only later see the hull.
Aristotle thought that the Eart was stationary and that the Sun the Moon and the planets and the stars moved in circular orbit about the Earth.
He belived his because he felt for mystical reason that the Earth was the center of the Universe and then circuler motions was the most perfect. 4:49
We seem to be talking about the universe as if there is only one. I love Michael Yorks voice, so soothing. Thanks God we had Stephen Hawking on this small planet. Thank you for this presentation.
@Oggy Oggy my mother is dead Oggy, who cares what she thought, she was entitled to have her beliefs. I have no urge to debate with you, got other stuff to do. May your sunny day be a joy.
@marjorie goodwin
Well you call something a god but what are its characteristics? For someone to call electricity a god is utter nonsense.
It’s a beautiful sunny day here.
@Oggy Oggy OK Oggy, I guess if I`m not you with your vast knowledge I should not have an opinion. Have a nice rainy day.
@marjorie goodwin
Yeah, that word is loaded.
I suspect you know nothing of the characteristics of this cause so to call it a god tends to bring a whole lot of baggage.
@Oggy Oggy Everyone has different perception of God. My God is not a religious being. For my mother, God was electricity, which seemed reasonable from her point of view. From my point of view, God is the first source and center of the Universe of Universes. I am not churchy, nor am I Christian. I actually am frustrated with people using the name in order to lord control over others. Perhaps mentioning God was a bad decision there where you read it, because it brings different things to all different minds. I have never had a filter, according to my elder sisters, so I type whatever comes to my mind, but I promise in no way do I wish to control anybody but myself, and that is hard enough work. Thank you for your very polite comment. You made me stop and think.
Awww I love listening to this while looking at starry night sky❤️
Michael York's smooth voice is hypnotic. Thanks for uploading~
I was literally just thinking “this guy sounds just like Michael York”!
I wish he did bedtime stories his voice is very calming
His voice was the only thing I didn't like about this audiobook
I listen to these to get back to sleep I am also very lucky to be a lucid dreamer so last night around 2 ish I put this on.
When I was a young man I was a cobblestone paver and I was dreaming that I was back on the job paving a new sub division and all the differy contractors were talking Physics believe me in those days we definitely were not talking about physics 😃😂 more like boobs etc lol

Thank You 👍...

Thank you!
Read the book and even better now listening to it with my eyes close
Very hipnotic voice reading , really enjoyed.
Great book this, Bill Bryson is also a awesome read/listen...👍
Very interesting stuff and it has been explained as simply as possible but not simpler (as Einstein would have said).
@Joe Angel By breaking it down into its simplist possible components and explaining it as clearly as possible while retaining the full value of the explanation. I'm not saying I understand all this 100% lol I'm saying Stephen Hawking did an amazing job of making this knowledge understandable to everyday people.
How?
I'm not a physicist nor do I play one on TV, but I have a feeling that the universe is not random but chaos dynamical. It is determinate but not predictable. That fits with quantum dynamics. I think that when we have a quantum description uniting gravity with the other forces, we'll be on our way to a quantum mechanical function for the universe and we'll see that as the function cycles through all the possible values, one or more of them will produce a probability of 1 or existence of a universe that supports life that can achieve what we have, at least. It would mean that we are living in one of several possible universes, which may or may not coexist, but we can't know about them if conservation of information is true. It's not the anthropic principle, it admits that some of the values in this function don't produce "us" and some work out without creating a universe at all.
I have read it 3 times and now listened to it 8 times. I think I get it...
Thankyou for posting this.
It is appreciated.
Michael York has a truly mellifluous voice.
The narration on this is Superb!!
Count how many times he says "black hole"....
lovely lectures 🕳️🖤🖤🖤
Gonna just keep it real - I didn't understand much of this, but WOW! What a listen lol
Instead of listening music to fall to sleep, I will start listening to these. Who knows, I may learn something during my asleep.
Started doing it a few months ago, although I probably fall asleep within 10m. Wish I got into audiobooks sooner
If you are looking for high quality audiobooks try Steve Parker audiobooks.
He has not done this style of book but has done classics like Alices adventures in wonderland, Treasure Island amd his 1984 and Brave new world are next level.
You will learn in your dreams, I promise.
I do this nightly too
Have this book.This is where it all started for me.
Tired biology student here, thank you for helping me pull this all nighter B)
a positive pressure exerted by the vacuum energy of space-time predicts;
-the accelerating universe
-gravitational lensing such as seen in the bullet cluster, where a region of less, higher density matter will warp space-time more than a region with more, lesser density matter.
-Matter in the outer regions of galaxies / clusters, should be moving faster than we predict
-Matter in the center region of galaxies / clusters should have added relativistic mass due to the additional vacuum pressure, increasing its escape velocity, allowing the stars in outer regions of the galaxies / clusters to travel faster than we predict possible without flying out of orbit
-we should measure there to be more mass than we can see
But this halo effect and extra mass being measures is explained by a positive pressure exerted by the vacuum energy of space-time.
Dark matter is a fictitious force, nothing more than the effect or dark energy on barionic matter(regular matter)
0:00 0:03 0:45 0:58 1:03 The Theory of Everything the origin and fate of the Universe by Stephen W Hawking read by Michael York.
Introduction.
In this series of lectures I shall try to give an outline of what we think is the history of the Universe from the Big Bang to Black Holes. In the first lecture I shall briefly review past ideas about the Universe and how we go to our present picture one might call this the history of history of the Universe. In the second lecture I shall describe how both Newton′s and Einstein′s theories of gravity led to the conclusion that the Universe not be static. It had to be either expanding or contracting this in turn implied that there must have been a time between 10 and 20 billion years ago when the density of the Universe was infinite this is called the Big Bang. It would have been begining of the Universe.
1:08 1:33 In the third lecture I shall talk about black holes these are formed when a massive star or an even larger body collapses in on itself under theory of gravitational pull according to Einstein's general theory of relativity anyone foolish enought to fall into a black hole will be lost forever they will not be able to come out of black hole again instead history as far as they are concerned will come to a sticky 1:37
Apparently, I am the only one to come across this in the last 4 months and to comment on it. It's a great audiobook to lisen to.
He said before he died that he’s has said a lot of bullocks in his life and people believed it 😂
Light is affected by gravity. I noticed that many years ago.
I commonly drop things when it"s dark.
@Alastair Staunton Yes. "I commonly drop when it's dark" would be saying that gravity is affected by light and the joke punchline doesn't match the setup at all. 6 months, 14 replies, 241 thumbs up later and no one else commented on that.
@Beena Plumber odder
🤣🤣🤣 Get this guy a Nobel!!!!!
@Kylen Donovan i try to forget passwords from instagram and facebook but by mistake i wrote them down 🙃
😂😂
Great book even greater man..
I never realized how much he sounds like James Mason.
As soon as we understand everything then there will be no reason to continue...
Always liked his voice MY, since he starred in The Three Musketeers
Have you seen this? There is only one theory of everything that actually includes everything! There is now convincing evidence that the universe is a living organism! The questions of what the universe is, where it came from, what it evolves towards, and how it relates to human existence-are conclusively answered in terms of morphology as they begin to arise from Plato’s forms and Sheldrake’s work on morphogenetics, but mostly by genetics itself.
Thank you, very informative.
Honestly, I was kind of hoping this would've been read by Stephen Hawking.
It'd be interesting and entertaining, but also funny.
Nono, I mean with the computer voice.
It'd be impressive to say the least, but it'd be more entertaining (to me at least) because it'd be really funny.
not to say miraculous.
The concept of infinity has always bothered me. If time extends forever forward and backwards, how is it that we are here now?
Innie minnie miney mo
Great voice and narration
I listened the whole book to add a single sentence in my new book which talks about singulaity.
What was the sentence?
@Saikrishna A New year.
Up at 3am listening to this after I just had a nightmare a grizzly bear ate my grandma
Thank you 🙏🏻
There is past present and future or why time goes forward and not backwards because apart from Hawking’s explanation of CPT, I would venture to say that it would be because we are sentient intelligent beings that happen to exist. We have been made possible by what I would call a Delta or a difference. A Delta T, Delta P, Delta D and so on even a Delta Emotion. The intelligent being collapses the wave function in a Quantum Theory fashion and fixes the point, makes a point real to himself (and others that share the same equipment as he has that discern a reality).
When the intelligent being realizes a point (having collapsed the wave function that represents the point or object) and examines it, he then may wonder, where was this object from, what is it made of, what happens if I drop it, etc. Where did the universe that we see come from? And then the Delta takes over and creates time each time that the intelligent being explores. He could not explore and he could not have existed if there was no Delta i.e., Change.
And each time he explores he collapses more and more of the wave function around him experiencing a world and senses passing of time.Entropy in a sense is a quality of time. If we conjure a glass of water (by defining, by collapsing the wave function) then the logical thing to ask yourself is “what if I drop this glass from the table?” So the concept of entropy is then defined.
But is it real? Only to the intelligent cloud that we are. If we (ourselves) did not collapse as a wave function we would be a swirl of forces combining now, dissociating after, recombining in a different combination or mixture later etc. Our existence is a brief flash but the deltas in our brief existence we choose to expand, think about, write about, dig deep into the rabbit hole about, create a Hubble telescope about, be Hawking about.
You what mate?
What is a wave function? In simple terms please. My quantum alert went to red while reading this. :)
Bravo
👏👏👏! wonderful wonderful!!!

I always wondered what Hawking sounded like. I was leaning toward Eric Idle.
Nature goes on forever for everyone and everything to return as everyone and everything an infinite number of times through evolutionary processes. 🌌
Nice voice ...and conveying tone..
this audiobook deserves an animated video content..
The search term that brought me here was "fantasy audiobook". Mr. Hawking was such a rennaisance man! ;)
So much better use of 3:30:00 than saying “Duh… god done it” then watching crap on TV for 3:29:57 😊
Of all the audio books, you’re telling me you couldn’t replicate the authors voice?
… I tried so hard to not write this, I even closed the app…
Time keeps everything from happening at once.
I don't know. the amount of world events we've had for the past two years seems to be hitting us all at once. 🤣
@Frank DiMeglio bro what are you talking about. That repeated mumbo-jumbo doesn’t prove or unify anything
@John Litwiniec It's still happening simultaniously we are just experiencing it in sequence. We just can't pull back to see them. Parallel Universes.
Thanks a lot for this
Lecture 1, 30 : 00
Lecture 2, 57 : 00
Thank you very very much. The voice was clear enough .I did not need to buy the book because of ur contribution.
Piracy for the win
I think that the most logical explanation is that: The expansion of the universe, although increasing for now, will eventually slow to zero, at t=P/2 (where P=period of the cycle), at which point it will collapse back into a singularity at t=P, a singularity that has EXACTLY the same characteristics as the original singularity. Once the singularity state (where all things are equal) is reached, it expands once again and the *same* galaxies are produced and the *same* suns are produced and the *same* planets are produced and the exact *same* lifeforms are produced and the exact *same* Humans are produced and the *same* websites are produced and the *same* Humans are reading this post. The implications of this are that everyone reading this now has (unknowingly) read this post many times before, and will read this post again, many 100s of billions of years apart. This theory fits nicely with the concept of the wave/particle duality because, in this case the SINGULARITY is the PARTICLE, and the RECURRING EXPANSION/COLLAPSE of the universe is the WAVE. Keep in mind that a WAVE by definition, has a cyclic nature defined by a period and has NO beginning nor end. Much like TIME, it continues forever.
Interesting thoughts but I have to disagree, but don't where to start (expansion/wavev function) ect as I'm tired. This was a great listen though 🌟🌡🌀⭐️🪐☀️
KAPAX much???
P=t/2 piques my interest. Is the t for trippin’?
@Adam Rice ha, you may be right
Fascinating listen bravo So deliciously refreshing too hear the dry humor and pettiness towards contemporaries us regular joes have a smug smile
Rico brilliant 👏👌
Still can't believe it is free 🙂
I would have been laughing so hard if this had been read by the author.
Can you imagine the book being read by the robot voice of Stephen Hawking? That would be amazing.
Really courious, did Hawking new the true shape of the earth?

@DAJORIVISION ?
The reader got great voice. Wish I know who he is.

Namaste thankyou Thankyou Thankyou infinite love light blessings to all aspects
@Dallas uggghhh a freemason
What are you on about ? This has nothing to do with the content given? I wonder if u comprehend any of it with a stupid comment like that.
@AMIT KUMAR I am of Indian heritage and a knight Templar...I have your knowledge checked many times over.. Seek God the Supreme master. WE ALL KNOW THIS FROM OUR ANCESTRY, MY FALLEN AND LOST BROTHER. CHRIST JESUS IS THE MYSTERY GOD, REVEALED TO US ALL IN HIS GRACE. FATHER EARTH IS THE ONE, OUR PEOPLE HAVE ALWAYS WORSHIPED, REVEALED TO US BY THE SPIRIT OF OUR FATHER'S, AS OUR LEGIONED HAS REVEALED. TO THE GREAT SPIRIT WE SUBMITT..
are you Indian or not
Smoke another one maaan.
So, I mean, Stephen had several physical disabilities and speech difficulty and motor skill problems, he definitely couldn’t have dictated or typed or written this book.
nice so relaxing
Excellent
Note, this is what 'The laws of Physics' is like in alternate universes, to us it would be complete chaos.
So good
This is NOT the audiobook to listen to when driving the car: unless you _actually_ want to plant your car upside down in a field, then be woken up to the sound of sirens and people shouting _''try not to move, we'll get you out as soon as we can''_
😂😂😂
Gravity!
This is gonna make my brain hurt. Time to grab the whisky and head to the roof.
I feel smarter just listening 😂
Is this the complete book?
43:46 science would progress faster if we focus on scientific facts and evidence, rather than antagonizing people of faith. I mean no amount of evidence will make me stop believing in a creator, for me it's all about the overarching implications.
Let say Hittler came to me with scientific evidence proving that he was correct, I wouldn't buy it at all no matter how much sense it made.
Did this material also come out under the name, a brief history of time? Or is that another work altogether?
Different book
Hawkins is no philosopher that's for sure. Narrators voice is good.
Who is to say that we won’t also be just a hash mark on a timeline of previously incorrect conceptions of, well, many things, including our place in the universe as we think we understand it today.
That hurt...
But....
I ❤️ it

I had no idea Hawking was so shady 😄
Hawking shat all over his own legacy when he employed circular reasoning to explain the origin of the universe: “The universe willed itself into existence.” 🙄
With what since it did not exist?
Great 👍
Nice story
