Andrei Linde - How Did Our Universe Begin?

Beginnings are momentous, the beginning of the universe especially so. How did the beginning of our universe happen?

[MichaelMcIlwrathJ]

These interviews are incredible. Brilliantly done.

[kadourimdou]

Yeah, bad sound. I thought Linde was channeling Darth Vader.

[Jarnagua]

This is my FAVORITE youtube channel, but you guys need to know that your SOUND LEVELS ARE WAY TOO LOW. Please tell whoever is mastering your audio to pump it up. It's impossible to watch the playlist because the intervening ads blow my speakers in comparison.

[thesprawl]

Why can't they increase the sound levels in their videos?! Every single one I've watched has the same low volume. They're barely audible, and they've done nothing about it since they started posting their interviews ages ago. This came out a month ago FFS. It can't take that much effort surely?

Just ridiculous.

[cvetkojovcevski]

is there any way you can turn up the volume up n your end uploader, please and thank you

[nadiraslam]

What's up with the sound guys? Come on!

Trying to understand how entropy develop from start of universe: at gravity singularity was lowest entropy, the small hot dense universe after inflation was higher entropy than gravity singularity, then entropy increase in general after big bang hubble expansion from small hot dense state of universe? Is this the correct development, or were there other developments in entropy? Was the equilibrium heat / temperature of the small hot dense universe before big bang expansion an intermediate state of entropy between lowest entropy of gravity singularity and increasing entropy of current cosmological constant expansion of universe? So as gravity expand with universe and gets weaker, temperature is cooler and entropy increases.

[jamesruscheinski]

What was the reason for transition from inflation to big bang hubble cosmological constant expansion at the small hot dense state of universe? Maybe when small hot dense universe temperature had cooled enough, expansion of gravity no longer reduced inflation below dark energy cosmological constant, instead going to particle and atom creation or other? Could the creation of particles / atoms from cooler temperature have required a rapid increase in entropy which became the big bang hubble expansion?

if every particle in the observable universe fell into one black hole, what would the rest of the spacetime be like?

[skyelarreed]

I can't seem to find the name of the interviewer ANYWHERE. Can anyone help me out? :-(

[jamesruscheinski]

Did inflation expand gravity from singularity? If so, did the expansion of gravity from inflation heat up the tiny universe to the hot dense state from which big bang start hubble cosmological constant expansion of universe?

[shirleymason]

Thank you. I enjoy. I will say though, our physicists/cosmologists need to come up with some new stuff for us non scientists (please). Even the Higgs and gravity waves are getting well used. And the "new" with that? It's discouraging that we get such news years after the facts are known, (or suspected). Bring it on.

[jericjaime]

Space or space-time without matter but with energy could be eternal with eternal properties to expand exponentially called "eternal inflation" causing "quantum fluctuations"defined as spontaneos excitation of the force fields of space which causes matter particles to be transformed or generated.This process happen on and on and on with no beggining and end, and it just happen that our universe is one of the many infinite universes being generated right now. How i love to be a cosmologist but i am not good in math to develop a model or a theory. Too bad

[jb_]

Awful sound recording...once again. Great subjects, great interviews, terrible terrible sound.

[doncourtreporter]

Stephen Weinberg describes a Planck scale sized area of quantum fluctuations which require no initial conditions. It's obvious.

[J]

A cubic cm of 'nothing' is a dimensional (extension) 'something' I would have thought:-)

[plnthn]

Forget about whatever the theists, and a few philosophers had coughed up over the centuries....their answers are heavily dependent on our ignorance....oh wait a bit here....ignorance ? I forget....ppl the scienctists has joined both the theists & philosophers on this topic...

[BradHolkesvig]

As soon as the first observer of the universe experienced life with his created senses, the program called Eternal Life began. We're living in a simulation that was created by a Creator who used technology that we can't see or understand. That's why He hasn't taught me what technology He used. He spoke everything we experience into existence without using any hands. We have computer programmers today speaking computer code and building programs with voice recognition programs. They don't need their hands to created simulations.

[marcv]

This is why I can not subscribe to inflation or the the big bang.

[RickDelmonico]

This sounds like a something from nothing explanation.
