It’s among the oldest questions because we humans are rightly obsessed by ultimate origins. Cosmologists can now explain back to the first 10-36 second of our universe - with the theory of “cosmic inflation”, which is what put the “bang” into the Big Bang. What is recent thinking on the beginning of the universe?

So glad I found it a few years ago. I just can't understand why there aren't millions of subscribers.
@@daithiocinnsealach3173 because thinking takes too much time and effort.
@@daithiocinnsealach3173 because actually understanding these topics ain't that easy, and people tend to look out for easy stuff.

How does Alan Guth not have a Nobel prize?
The conversation is deeper than the river flowing behind them. It is good though, we have people who understand this stuff, to the benefit of us all... one would hope.
Amazing background
The looking glass.
And here we are, on our planet, in one little section of the Milky Way galaxy trying to figure out the universe. I love science. We will get our answers someday.
We will never have all the answers.
There will be no final answer. Like Alan says, if the entropy is infinite, we can not have a final equation, a final answer
This channel is simply wonderful. Keep up the good work!
the editing is great and makes these videos easy to absorb and feel like the watcher is part of the conversation ... bravo
Guth is one of the best. You could warm your hands near his head.
Inflation happening earlier than we first thought is what I've gathered from recent videos, especially those with Roger Penrose, in which he talks about maximal entropy & space winding up at the end of this universe/aeon as geometrically identical to the low entropy tiny beginning stage
Very good explanation!
Excellent content.
Alan’s the best
Such a beautiful location.
wow! absolutely fascinating
Amazing background !
Where was this recorded i want to be there
I want to just sit there and listen although I guess I’m doing that on my phone right now
Seems newer recording.
Guth...brilliant, brilliant, brilliant man.
so level 1 multiverse is finite and not infinite , ok
but if it's bigger by 1000 time is this in volume or in distance ?
Could energy of inflation come from time field? And could there be a time field (scalar?) beneath the vacuum of space?
What's the name of the interviewer?
Who chooses these gorgeous locations? Damn! Do you fly these guys out there?

This universe began when two mega black holes collided. The resulting debris field became our universe. It is spreading in every direction due to the gravitational pull of the other massive black holes that surround this universe. Our universe will eventually be absorbed by those surrounding black holes.
Alan Guth, Joseph Silk, John Barrow, Martin Rees, Ed Tryon, Andrei Linde, Alex Vilenkin, Ed Witten are all good writers.
I'm looking at that beautiful river flowing behind him and thinking, "quantum fluctuations huh"?
If, as some people say, the universe was infinitely hot and infinitely dense at its beginning, how can it ever be anything less?
I don't even want to say this, because it's not an answer. Temperature and density.... Temperature is the kinetic energy of the structure of molecules and how fast their moving comparrr to other stuructures/molecules.Density is the amount of total mass of a structure.
It is rather hard to assume that a concept like entropy can be used to describe the evolution of the universe even from incipient stages . A concept introduced in mid 19th century that dealed with thermodynamics . Today we are dealing with dark matter and dark energy which we don't know what they are yet and we can't guess where they will fit in with thermodynamics.
John K maybe dark matter and energy is the back up copy of the universe ?
@@cajones9330 It might be in the cards ,although they are still mysteries around dark matter and dark energy . Not sure if the physicists are ready for a new paradigm, so they are still comfortable with the older concepts.
That last idea of a mirror Universe is interesting, but I don't see how you would ever know it was real. The issue is Math can explain a large set of options by changing the variables, but that does not imply or mean that those states exist. We cannot know they are real in other words, as we would never interact with those parts of the multiverse. There is a lot of metaphysics in this that I could see being possible, but I guess application is my real question. Where is the application for this? How do you know it is real?
Fun to think about though, I can see why he does it.
@eric thefathead
True
Whenever a scientist repeats , "good question , good question" , he/she is in trouble explaining a core feature of a theory.
Besides the highly problematic assignment of probabilities to "everything imaginable happening , does happen" scenario in the infinite spawning universe to the different ill- defined notions of "something from nothing", this is looking more like turtles upon turtles ad infinitum.
And where exactly is the infinite energy coming from for the generation of infinite universes?
Drawing a one to one correspondence between purely mathematical notioqn and physical reality is highly problematic. For example, a mathematical notion of a point has no correspondence in physical reality. So, when we say a point particle in physics, we mean for all practical purposes, let's ignore the dimensionality of the particle . However, this is only an approximation. No one would jump to a one to one correspondence and say nature has zero dimensional particles.
Similarly, while the mathematical notion of infinity does lead to interesting mathematical results, it would be incorrect to draw a one to one correspondence between the mathematical notion and the physical one. Mathematics can be used to model, but never be used to draw an ontological equality. It would be a category mistake in the Aristrolean sense.
An initial inflaton field cannot have infinite energy as potentiality. Even guth has acknowledged that the universes are "ultimate free lunch" in this theory because one has negative infinite gravitational energy to balance. This seems like an accounting gimmick worse than the subprime loan accounting of 2009 financial crisis. Starting out with the implied assumption of potentiality of infinite energy is like postulating an infinitely omnipotent omnipresent, omniprecient God.
What does Guth say at 7:17, where he spreads his arms? “Because it’s low compared to the …. Background?” This seems very important, but he mumbles it and moves on.
I personally believe our pocket universe is simply a weird little run off of matter and energy. I hypothesize that understanding what our universe is and what it is in/connected to (also linked to other dimensions) could be solved with essentially zooming out. I believe we are the ant crawling across the floor unaware of bigger perception that the human may have. Obviously like most armchair philosophy this is simple, and I will be honest I have far from a full understanding on any of this science on the data level. Its honestly like those trippy infinite loop videos that just keep zooming in.... what zoom level are we on?
As a layman on this issue, I'm confused. Doesn't this still require that *both* arrows of time have a common *thermodynamic* beginning "in the middle" of this hour glass (for lack of a better way of phrasing it)? Aaron Wall insists that this "would raise the same sorts of philosophical problems that any other beginning would" (I'm paraphrasing, but that's close to verbatim). So then how do we explain *that* beginning?
The universe is a transformer.. there is more to it than meets the eye

Gamma waves for example.
Statistically speaking there has to be a few who press the dislike button. They're just doing what they were destined to do... 😂
Yep on atheism there is no free will
God in the palm of his hand and with the breath of his mouth spoke heaven and the earth into existence... so simple.
God has hands and lungs and mouth and uses air? I hope God doesn't get pneumonia, especially with this Corona virus. I guess if God has lungs and breath he must have a cardiovascular system too right? Hope he's eating a healthy diet and getting exercise so he doesn't have a heart attack.
I really doubt that there was a big bang. Maybe a controlled expansion. . It appears to look like a big bang. But if a pendulum is pushed from a half way starting point it might feel that the pendulum came from a higher position or potential energy.
I agree. There was no big bang and there is no evidence for it. Sure, there is a general inflation evident, but there is no need to invoke mystical forces to explain it. As far as I’m concerned, it is as simple as an extension of the energy released by galaxies, as a result of the energy of the stars within them. The galaxies are pushing each other apart. This not only explains inflation, it explains all the other obvious phenomena, like galaxy collisions, which cannot occur as a result of an all-encompassing background force.
How could it be possible for people to live in a backwardly moving dimension of time? It's hard to imagine dead corpses springing up from their graves to unlearn what they learnt, unspeak what they spoke, uneat what they ate, unmarry who they married....and "unlive" the whole again in a backward manner until one day they return to their mother's wombs.
As a Taoist we think : somethings can never be known "...

The title if the video is : Alan H, Guff- How did the Universe Begin.....
And his answer was....well, we don't know.."there are different versions of nothing'' etc.
Why couldn't he be honest and say, " I haven't any idea how the universe began''.
And how can there be different versions of Nothing? How can there be any version of Nothing?
Nothing is Nothing.
I can explain you
@@mihaiserbu8447 Please explain then.
Yeah but why?
In another universe, There is a universe asking another universe how Alan Guth Began.
If the entropy increases in both arrows then you may as well have two universes going in the same direction. Math must conform with reality.
The universe is a terrific simulation done by an advanced. type 3 civilization that created Earths inhabitance .

Are you on Crack or LSD?
We see the event horizon because it is always NOW and you cannot see beyond the now. The past no longer exists and the future does not exist yet. Therefore it is always now and at the EDGE of the universe is ALWAYS THE continually creating NOW.
I'm glad you guys didn't get eaten by a bear in banff
I like to keep things simple so I compare the univer to Lego land. Now how did Lego land begin? It is another world/universe in a sense. Before the Lego brick was invented there was no Lego land. So in the beginning there was tiny bits of plastic(matter)and there was heat (energy) involved and there was molds (space) and there was pressure (inflation ). Now someone designed these components and systems and put everything into motion starting a process of creating Lego Land. What was there before Lego land that created it? Could it have made itself? Given millions of years could it evolve by chance? By natural selection? What are the chances of it ever happening without intelligent input? If we can't come to understand what is needed to create Lego Land, I think we should stop trying to understand how the univers began. None of the Lego Land people wonder who created them: I wonder why!
I think as far as knowledge goes we are doomed because in the end we have to take 'something' to be 'existing always'. No further questions asked!!
This thing can be God or (laws + energy). After we have reached this stage, we can't question anymore. This inexplicable certainty is the fate of all human quest for knowledge.
In this sense, everything (whether God or ever existing laws+energy) is Supernatural because both these options defy logic/explanation.
Both men are impressive.
There was something impressive in what they said?
I missed the ''impressive'' part. Can you tell me what was impressive...
@@glenemma1 "The sole of man is eternal" and "in my correct opinion"
@@tomingrassiaimages8776 What are you talking about? No one in this video said, ''the soul of man is eternal''. And I'm sure Guff doesn't think that.
I'm sorry, but Guff is clueless.
The title of the video is "How did the Universe begin?''
Guff has proven that he has no idea, actually has less of a clue than the average man (or woman) in the street.
Fluctuations is code word for "we don't really know"
I think it would be hilarious if the video stayed blurry for the whole interview. Or, alternatively, the video unblurs, but during the interview, Leonard DiCaprio's character from The Revenant floats by in the river.
Good thing the laws of physics created that bench, so they could have this discussion.
Big bang was a beautiful way to transfer religious concept of creation by intelligent creator to a language of science. Inflation is most obvious, intuitive way to imagine how Big bang could look like, with regards to what is experience based logic for a human mind and without violating any basic physical laws. Scientist are gathering many kinds of data, some fit in recently perfected hypothetical model, other are not anything conclusive or at least doesn't directly contradict idea of inflation. So model is probably not how it really happened, but is consistent enough to give researchers some kind of theoretical backbone they can follow and organize their research around it. They don't need a better idea, tools and methodology will improve with time and gathered data will lead to new ideas in their own, without any distracting ideology.
"How Did the Universe Begin?"....a much better question than the "why" dumb question of the other video.
People under estimate how genius this dude is. A real, freaking genius right there, on the same level than Elon Musk. Been a fan for years, never cease to amaze me.
You must be joking? You just compared Alan Guth to Elon Musk? My friend, this guy isn’t even on the same planet, intellectually speaking, as Elon Musk. He would run circles. Don’t compare an over-glorified businessman with a brilliant theoretical physicist, it’s actually insulting.
I dont think u know what ur talking bout. Alan guth is a physist. Elon is not on the same level
Whatever Universe was before was materialized, energy had to be sucked from it's source to a new dimension, creating space time in the process. Could be anything else really, but if we want to continue with materialism, we should conclude patch of something was exhausted by inflation or equalized by pressure of nothing nothing in this dimension. This would mean no multiverse is possible, because there was nothing left inside a singularity source. But if Universe just spilled some stuff, there must be regions of space where both dimensions are still open and mix together from an infinite source, at least i can't see any obvious reason how flow of inflation could seal the leak.
Maybe the energy was created. It can't be created in this system.
@@daithiocinnsealach3173 Energy = gradient of something from two or more sources. This would imply there was potential difference from dimension of origin and a new created one. This means we are talking about same stuff, just from different perspectives, it would be very disappointing if it turns out Universe came to be from another form of the same.

It's really cute how theoretical physicists come up with non-observable fantasy land scenarios yet most of them think the idea of there being a God is preposterous.
There’s an evidence, that why did not stops !
What's this guys stance on "climate change"? That will tell me much more about him than his theory is about the how the universe was created. One issue matters, one doesn't.
All I hear is water

Sorry guys. I wish you all the best Alan, however youve gone down the wrong path and invested yourself in fantasy. This proverbial limb isnt going to hold indefinitely. Maybe you could still retreat out from upon it before it goes
At the beginning of the universe all space time matter and energy were created. In Genesis 1:1 we gsee that too. In the beginning (time) Elohim created the heavens (space) and the earth (matter).
Bollocks!
Why don't they ever talk about why there should be inflation. There is no explanation for it too speed up and slow down. Penrose makes more sense imo
I remember when scientists laughed at the notion that God created the universe in a day, now they want us to believe it happened in a microsecond
Human animals are an ignorant bunch.
No, they laughed at the God part. The day part was ancillary nonsense.
Would not the time of these scientists be better spent solving global warming
These guys are physicists, not climateologists. Stick to Fox News, troll dung.
In fact the solution has been known for quite a while, and the scientific community has insisted on the measures to be taken to halt it, even with schedules and everything. Yet the rest of us have either been slow to act, or chosen denial for a number of years. It happened before, with the ozone layer hole, which was announced in the 60's/ early 70's but action was delayed for a couple of decades, and it's happening again. We're slow in learning, but quick to complain it seems.
There is no man alive that knows the answer to this universe. Send a letter to the dead in the alternate universe... maybe they can help you out

You have to assume you know the answer in order to make a blanket negative pronunciation in regards to everyone else's ideas.
This is not good .. one of them is stealing a wage.
They don’t know. No one knows.
Da Koos but it doesn’t mean that we should stop exploring and trying to find these answers.
No, but it does mean that the title should change.
Give them more of our taxpayers dollars so they can live like crooks.
Its his view of how the universe began so the title is accurate.

It would be nice if physicists admitted all the flaws of their theories as well.
He seems like a super smart scientist, but then he says crazy stuff like infinite universes, or infinite infinities, or worries because inflation won't stop making universes. These ideas are so childish and stupid that only the super smart could believe in them.
What a dorks
Well not by a God.😂
Guth is getting as old as the Universe.
Oh , that's easy to answer .
One day , God , The Creator of everything and all knowing and seeing got bored. He got bored being alone in this black void He was in .
So , He decided to summon a fallen angel he used to have in His dominion, Satan , The Devil .
God said , you Satan and I , God The Creator , will have a fight in a new place I will create called the Universe.
I will cast you into the depths of fire in this new Universe and I will create life and man , and everything else ,into the rest of this Universe, so I can never be bored again.
So God got bored and decided to have some entertainment , and created to Universe , period!!!!
No need for all this science and physics , simple.
Those of us who press the dislike button know that however highly educated people are they still have to guess how the universe began and they ignore the only eye witness, the Creator.
This is proof that god never existed. I'm glad the religious have given up their beliefs. Finally
If only that were true. We'd live on a very much happier planet.
Nietzsche proclaimed God was dead some 100 years ago, society has become more interested in God than ever. Nietzsche was wrong. It was the atheists who hated the big-bang theory last century, not the theists, moreover, it should be stated that your assumption that religious people are stupid and unscientific goes without saying is factually false. The last hundred years of Nobel prizes have seen 65% Christian winners, 20% Jewish believers and less than 7% that declared themselves atheists or agnostics, it was a combined category. Aside from this, most of the atheistic and agnostic winners won in literature, not science.
This is a fairy tale with absolutely no evidence. These guys don't know what space is or what time is or where matter came from but they speculate on how the universe began. Don't you find that extremely arrogant?
What a foolish statement. They're just humans with curiosity groping around, admitting they lack the full knowledge. Nothing arrogant about it.
@@vgrof2315 When they claimed that there were different types of nothing and the universe came from one of them that is either arrogance or ignorance.
