What Linde described beginning at about 12:58 -- the problem of how to explain how the Big Bang started at exactly the same moment throughout the small hot dense clump of primordial mass -- finally helps me understand why Feynman assigned a strange homework problem in a class at Caltech that I audited in the 1980s. He called it the "firing squad" problem. Suppose there are N members of the firing squad arranged in a row. Each member can communicate only locally.. only with its nearest neighbor on its right and its nearest neighbor on its left. They can communicate only at regular periodic intervals (like cellular automata). None of them know how many members are in the squad. All of them are programmed with the same communication & firing algorithm. Their goal is to all fire at exactly the same moment. Assume that at a random moment, one of them initiates the (local) communication that is to eventually lead to all of them firing at the same moment. Design the simplest algorithm that achieves the simultaneous firing goal. Feynman didn't tell us why he wanted that algorithm. But it would solve the problem Linde described, in a 1-dimensional toy primordial universe. So I'm guessing the Big Bang problem is what motivated Feynman to assign the "firing squad" homework. I submitted my solution, which seemed reasonably simple. But I don't know if it was the simplest algorithm, because Feynman didn't review any of the answers with the class.
Wow I've been huge fans of Guth and Linde for years for their work on inflation. What a treat to see such a competent interview with both of them by Brian Greene.
Sometimes I listen to people telling about random political issues or about random garbage drama. When I come here I think to myself why waste a second on something that isn't enlightening like listen to Dr. Greene speak?

Im 60 this year and I can remember thinking about where is the end of space, when I was about 7 years old. Is there a birick wall? But what's behind that? I know you guys know heaps, but at 60 I still can't get past what was before and where does space it end? And if it never ends, what does that mean? Sorry Im so basic, however I love watching this stuff and I kind of understand upqurks down quark nutrinos etc.
Inflationary cosmology suggests that the universe experienced a rapid expansion in the first moments after the Big Bang, smoothing out its initial conditions and leading to the large-scale structure we see today. This theory addresses key problems like the flatness and horizon issues, and supports observations such as the uniformity of the cosmic microwave background.
This was a great segment. The question I was left with is: How do dark energy (DE) and dark matter (DM) factor into these theories? At some point they must be accounted for. What are the possible mechanisms for integrating such? Also (and I think [maybe] relatedly), the previous segment here on DESI indicates the employment of baryon acoustic oscillations (BAOs) as measures of the effects of DE & DM. I am not clear on what mechanism in Inflation would manifest BAOs (or if Inflation is required for BAOs to form). My first intuition is that BAOs formed after the Inflationary period (were they "locked in" during or after cooling?), and also, that they manifest across larger spatial scales. Still, given the euclidean nature of Space-Time, it would seem BAOs are dependent on Inflation. So any effects of DE and DM on BAOs should also inform the parameters for Inflation. Am I thinking about this correctly?
All particles in the universe are entangled, since the big bang? Thank you for your comments! The purpose of my question was: "It is GOOD to think about a beginning of our existence as the Big Bang Theory"🌈
The universe is made from an expanding quantum energy field. Matter emerges from there too. Particles are tiny waves, not solid mass. They are all connected, as are we, in and of that expanding quantum field. Particles are tiny waves within cosmic sized waves.
Imagine our universe was like a tiny microscopic bubble presurized in a sealed bottle of champagne then something removed the cap and all the bubbles within rushed out and expanded i think we are one of those bubbles foerever expanding .
Imagine if there is just one observer. He is lonely and bored. And he wants to create someone else. He just split in two and made others. Then others split in two and so on. So everything starts from just one who became many. "THE POWER OF ONE THE POWER OF TWO THE POWER OF MAAAANYYY."
Prior to inflation, the universe was within an order of magnitude of the Planck length. The early universe was very flat. Entropy increases to further flatten any variance. The forward flow of time is just a return to nothing.
So far as we know (according to the Lambda-CDM model of cosmology) the universe began from a random quantum fluctuation. It may not be entirely satisfying, but that's where we are. It's either that or a cyclic universe model like Penrose's Conformal Cyclic Cosmology, in which the universe constantly expands and then contracts again, forever. But even in this model there _had_ to be a beginning at some point in the past... Have a great day!
When I got tired of all the “noise” that the news these days talk about, as if I am forced to care about all the issues that I cannot solve or do anything to change the outcome, I just like to listen to World Science Festival. It makes me feel like there’s a bigger more powerful force out there that we cannot comprehend, and I love listening to these smart people talk for a change.
You don’t need expansion if everything is still connected via a dimension of zero length and size. Or effectively a singularity. At the start of the universe everything was at a singularity point, there were no dimensions and everything was connected at the same non point place. After the universe began expanding maybe this single point dimension remained and all matter and energy has become entanglement within this point and still is. This would also explain why entangled particles in our 3D (4D if you accept time as another dimension) universes can affect partner particles across huge distances instantaneously. Basically the conditions where everything was compressed into a singularity are still in place and we are all connected to a point via higher dimensions to (or lower dimensions) via this original start point.
There is to much stuff to produce a singularity. If we condense all the matter we know of it can't fit into a single point since we reach plank density before that point.
I don’t buy the idea of repulsive gravity. The hypothetical matter doesn’t exist. This concept seems completely contrary to all observations of the behaviour of matter. There is no such thing as negative mass. Richard
So is the reality of the entire universe and not just the visible universe most likely closed at a massive scale? If it wasn’t flat before inflation can it somehow transition to flat? This doesn’t seem possible.
As if to commentarily represent your colleague & 1 other pioneer proponent of Inflation, Alex Vilenkin, the problem of the physically unknown "beginning"' or the beginning 'singularity' in the original BigBang turned out to be unavoidable even in the Inflation Theory.

Yes the universe is expanding but also pushing up higher,it's ice melts, spreads and when water is filled,the level goes higher.The universe will one day disappear from us.We will have to swim deeper sea and search it 🤷🏾♀️...my imagination 🤔
In my opinion, we may see boundaries of the inflation when a system is changing seriously. For example, Earth may be changed if many keys of earth elements (including livings…) are making critical changes; The solar system may be changed if one or two planets are destroyed; our galaxy may be different if one or more solar systems are changing their shapes. If things from a system are adapting changes quickly from the inflation, then the system is going back originally state faster, and we may not see its effects.
One must remember that inflation was proposed to explain the unresonable flatness and homogeneity of the observed universe. The other option of course, is that the initial conditions were so perfect that perturbations were so minimal as to have little effect until the era of recombination. Proposing such perfect initial conditions is problematic for a materialistic origin of the universe.
Dark matter phase transition would explain the temperature across the universe if everywhere condensed at the same time it would all be the same temperature due to this universal dark matter heat absorption.
Seems that inflation is not nessesary if there wasn't a Singularity. I/E the universe was never that small. To date no one I think has ever gave a satisfactory reason as to why it ever had to be that small before it expanded.

Dear Mr Green . Isn't inflation of the universe creating it's own gravity.

The increased rate of inflation is increasing gravity throughout the universe. And I don't mean dark matter. 🎉

The 8 planet solar system, is this a design to sustain life by a creator or chance that has occurred many times in the observable universe.
Immensely impressive presentation. Shame iInflation is wrong. Infinite universes is just plain silly. Not me. Prof Neil Turok has a solution, that answers numerous outstanding cosmological questions. Inflationary cosmology cannot be tested and predicts nothing that can be found.
You know these guys have hit a brick wall when they start talking about tiny dudes sending signals to each other in order to regulate the temperature of the CMB. Ouch! Kind of embarrassing for the human race.
In my humble opinion, there must be something before the big bang but what was it? And if space is expanding it must be expanding in to something. Also in my opinion everything has a limit. For example if you poor water with a hose in a swimming pool after a while the pool is full and the water would spill over. So if space is expanding like the water, what is it expanding in and when will it spill over and in to what?
all good, but inflation cannot be a theory, it is at best a fine (up to reasonable accuracies) mathematical encapsulation of what we currently seem to observe out there in the universe. if otherwise you consider it to be a predictive fundamental theory, you indeed end up in this multiverse something, in which case everything just sounds nuts, especially if you wanna bring it on the same ground with the situation in quantum mechanics. those multiverse arguments resulting from inflation have nothing to do with quantum theory which instead is a non-factual description (until you measure for which you have to make use of the born rule). the response starting at 1:03:00 is just pure nonsense.
The Big Bang theory is in serious trouble following the observations of JWST. The false assumptions of the Big Bang theory are: 1. Matter all formed at the same time rather than over an extended time period. 2. The explanation for the cause of the CMB 3. The cosmological principle Richard

You know these guys have hit a brick wall when they start talking about tiny dudes sending signals to each other in order to regulate the temperature of the CMB. Ouch! Kind of embarrassing for the human race.
Listen to that part again because you missed the point and/or you don't understand what metaphor is.
In my humble opinion, there must be something before the big bang but what was it? And if space is expanding it must be expanding in to something. Also in my opinion everything has a limit. For example if you poor water with a hose in a swimming pool after a while the pool is full and the water would spill over. So if space is expanding like the water, what is it expanding in and when will it spill over and in to what?
The word you're looking for is "pour," but we got it anyway: it's going to be a while before you join the conversation.
Outside the universe is nothing, there is no "space" outside the universe. The expansion of the universe is the creation of new space.
Kun level 8 nothing
There is no before time starts.
Guth did not "discover" inflation he created it. You can find less fudge in a Cornish sweet shop.
all good, but inflation cannot be a theory, it is at best a fine (up to reasonable accuracies) mathematical encapsulation of what we currently seem to observe out there in the universe. if otherwise you consider it to be a predictive fundamental theory, you indeed end up in this multiverse something, in which case everything just sounds nuts, especially if you wanna bring it on the same ground with the situation in quantum mechanics. those multiverse arguments resulting from inflation have nothing to do with quantum theory which instead is a non-factual description (until you measure for which you have to make use of the born rule). the response starting at 1:03:00 is just pure nonsense.
Those that deny that God was the "bang" in the big bang, will spend eternity in outer darkness. Eternity is a long time to waste.
AI will solve all the problems
The Big Bang theory is in serious trouble following the observations of JWST.
The false assumptions of the Big Bang theory are:
1. Matter all formed at the same time rather than over an extended time period.
2. The explanation for the cause of the CMB
3. The cosmological principle

Inflation is particle may kicked particle cause universe to go into it's inflationary mode
Always most respect every scientist and every Scientific wing and my real study is Scientific world. Almighty Allah give me Scientific opportunity for Scientific study. ET1
All the Greek gods live in the Gaia space.
This universe is just a skin cell of Zeus, and Gaia space is just a body cell of the taller God I. 🪆
Gaia space expands first and then collapses.
No
🫐🦕✌
if the universe is flat, therefore the earth is flat according to calculus, lol
Rubbish!
It's like watching professional tag team wrestling! Entertaining yes, but I hope no one gets injured by the arm waving 👋👋👋 Nacho Libre!
With the inflationary theory, could the inflation be caused by exponential new stars being born?
We just can’t see it yet. 🥹
