    The fact that it looks like his mouth isn't moving gave me a good chuckle

    Did he said that inflation happened before the big bang? If he really said that, it's kind of hard for me to buy this. Or to conceive it i should say.

    Put your faith and trust in Jesus Christ For God so loved the world that He gave His only begotten Son, that whoever believes in Him should not perish but have everlasting life. For God did not send His Son into the world to condemn the world, but that the world through Him might be saved. “He who believes in Him is not condemned; but he who does not believe is condemned already, because he has not believed in the name of the only begotten Son of God. And this is the condemnation, that the light has come into the world, and men loved darkness rather than light, because their deeds were evil. For everyone practicing evil hates the light and does not come to the light, lest his deeds should be exposed. But he who does the truth comes to the light, that his deeds may be clearly seen, that they have been done in God.” John 3:16‭-‬21 NKJV

    If its truly isotropic and relativity is universal wouldnt it be spherical just as the observable universe is ?

    While I consider Multiverse theories wrong headed, I enjoyed Andrei's lecture -- given as always with self deprecating humour. Dear Andrei just because you and your colleagues cannot conceive of inflation without multi-universes, it does not mean you are right. I am a very simple guy -- so give me theories based on our universe and the 4 dimensions we exist in -- please stop solving your maths problems by ever more wild expositions of fantasy -- start looking at the gaps in what we understand, the gaps in what we can measure and work out how we can fill them in our reality. You say X,Y,Z cannot work without extra dimensions or we could not be here without their being infinite alternatives -- I say this just makes it more and more clear we do not understand reality well enough to be able to generate viable hypotheses that can actually be tested. To the infinite universe hypothesis - I have to say SO WHAT !!! Even if you are right, which I very much doubt, so what !! It make NO sense wasting times on multi-brain theories or in developing the maths of the multiverse. You asked for better ideas -- mine is to build better tools to explore and understand our universe in our 4 dimensions AND to develop theories CONSTRAINED to using this universe and the 4 dimensions we can see and measure. TRY THIS for a while. Try codifying what we don't know; adding the "missing" terms to the Standard Model to reflect: Gravity, Dark Energy, Dark Matter, Dark flow, Baryon asymmetry, and the reason why some of the largest structures in the universe are larger than expected -- even though we do not understand them, we must take some account of them.

    Not that I know enough... But once we define life correctly, we'll find that biology is the ultimate evolution of chemistry, what we think of as consciousness is the ultimate evolution of biology, science is the ultimate evolution of superstition and we'll redefine God as a set of 20+ constants from which, the quantum particles were permitted to practice the Google plex number of combination on the fabric of space time for lack of a better definable concept, to leave behind the most universe at the lowest energy cost of matter. Critical mass seems to be a constant law, in how the Continuously expanding universe seem to be a medium that ultimate gravity can bring back together all the mass that can fit on a head of pin and blow up on an existing vast space time it had created from the time before. Maybe on every rebirth, it expands faster because it has thinned out the fabric with the fields of its particles trying to come toward zero energy. It's a nice thought experiment without clutter or glitch. Maybe gravity is never going to unite with nuclear forces and unified theory is a good enough excuse to Exercise expanding our consciousness in the web's we weave in explaining parallel and alternate universes, being the current superstitions in the way of what we can never know with our time Restricted existence. I hope you're smiling.

    Used to be a big fan of Andrei, especially because he often share the stage with Alan Guth who I truly appreciate. But then over the years, and after watching Andrei debating with other fellow scientists, he lost a lot of my respect. Im not a hater don't get me wrong, a lot of respect for the man and his work. But ...In an open debate with fellow scientist, he become extremely defensive and immature. In one debate speficially with Paul Steinhardt, he was arrogant, close minded, and had no answer to any questions, and simply ended up laughing hysterically like a kid. I understand there is a lot at stake, his carreer and his legacy... but any good scientist MUST be open minded, especially toward his own work. While Andrei is laughing like a 8 years old kid, Alan Guth simply aknowledged that there are flaws in the theory, and that it is in work, which is the good thing to say.Someone so close minded almost remind me of religious people ... So yeah, good in front of a class where no one can say a word, but not so good in a group where his idea are confronted to real problems. Sorry for the negativity, I really had to get this out of my chest. This is not what science is about.

    Roger Penrose has an alternative to inflation and the multiverse: conformal cyclic cosmology. I hoped Andrei would get into it a bit. :-(

    The multiverse, It is suggested, is only a piece of the larger puzzle. It is part of a Super Multiverse.

    Why just asking me to my point of vue. I am easy to comunicated send me email and I give you my phone#. I realy worry about the nucléaire fusion. I worry because first a sample lighter cause many Firehouse cigarette smoking so on. Now manipulate fusion it is not fision wright. With my hypothèse or theory what Ever you call it, long time ago I did this prédictions That occure today. I dicided to make it basicly invisible but I fail. We talk about fusion still. Now I am extremly worrie about it fusion. If you need Energy ask me. If you need propel your self in the galaxy what ever it is ask me. You all of you start for too long speak about as an evil. IT is like a man who do that free of fame,free of cash and free of help should be a evil! Why never all of you instead of make me a monster dont say the world that me my self alone a humman give all of scientific communauty and alot more wayst your time too scare the world about me instead of calling me an go what ever you whant. I am a man of my words I dont have to assume all your shit but as usual I help all of you alone with not even a thanks after your all satisfied. Too busy to say it is you discover the hole thing. I know it is propably very embarassing to call me. Do as I am a good man I will never be Mad at it. I dont care it is in your hand. Never , never again you should masking me from the world they have the right to know my opinion. Philippe Martin quantum Physics 😎

    Dark Energy could simply be Multiverse gravitational energy. The accelerating expansion of our universe may be the only indication that a Multiverse actually exists. The phenomenon could be explained entirely by General Relativity. No magical property of space needed.

    It's either God Almighty or the multiverse theory. It's the latter because the former is untenable, according to Holmes's logic.💕 ☮ 🌎 🌌

    the problem i see with eternal inflation is that it predicts that we should live in a much earlier universe. since new universes are being created at an exponential rate so that far more universes that currently exist are made every second (i forgot the numbers exactly, not sure if there's any definite prediction but it's something like 10^30 or more) it means that new universes with life in them that spawned conscious agents even a thousand years earlier than it did here would be drastically more plentiful than ones as old as ours and the further you go back the more true this is, and to my knowledge there's no reason that evolution couldn't have happened say 1 million years quicker, or on a planet a billion years younger than earth, etc.. I believe Alan Guth is aware of this problem himself and termed it the 'youngness paradox'. is there any solution to this problem? I think it's pretty damning to the theory.

    I sometimes wonder what the human race would be like if instead of people watching things like Towie, X-Factor or Big Brother, they was as interested in science like this as much as I am. The only way forward is Education. Educated youths normally grow into informed, Educated truth searches. But I cringe when some of the people of our population open there mouths and nothing but complete moronic gibberish comes flooding out. The people that can watch this and understand enough to follow are increasing in numbers slowly but surely. Come on people, lets not let stupid win. (Hopefully stupid will fade away into a Darwinian cul-de-sac)
