Mysteries of Cosmic Inflation | Episode 906 | Closer To Truth

The very early universe likely underwent a period of enormous expansion called "inflation." The theory stunned cosmology. Here's the story of its discovery. Featuring interviews with Alexander Vilenkin, Alan Guth, Saul Perlmutter, and Andrei Linde.

Imagine being the person who's realizations helped to illuminate a gigantic portion of one of the biggest questions ever posed by living beings.

[michaelsinard]

I wish i knew more about cosmology/physics to understand completely. I've viewed CTT on pbs, its great.

[Okla_Soft]

Amazing interviews with those 4 guys. Alan Guth and Andre Linde really are like explorers uncovering uncharted land. Eternal inflation fleshes out our idea of what space really behaves like in the first nanoseconds of time after the singularity. Excellent episode .

[lordemed]

Why has Alan Guth not been awarded a Nobel prize?

[timwoodruff]

OK, my mind is blown. The size of the universe compared to the multi-verse out there is like comparing one atom to our entire known cosmos??

We live in a universe that is both incredibly large and yet quite tame. It's made of matter, space, time and energy. The laws of physics are the same everywhere as far as we can tell. The universe also has a tendency to form structures that are self-similar everywhere, from the largest scales (galaxies) down to small scales (atoms). This is called 'scale invariance'. Scale invariance is a property of systems like our universe, which are in a state called 'metastable' or 'critical.' It's the reason why we see fractals and self-similar patterns everywhere. The universe is critical because it has just enough energy to form structures but not so much that they will destroy themselves by collapsing. If the universe had too much energy, it would collapse. If it had too little, nothing could ever form and there wouldn't be any structures. This is why the universe appears to be fine-tuned. It seems like there had to have been a creator that made the universe this way, so that it would form structures and not collapse.

However, the universe is not fine-tuned at all. It's actually very simple. There are two basic forces in this universe: gravity and expansion.

Someone should let the producers know that inflation isn’t actually a universally accepted/proven theorem and is instead, in particular recently, having substantial holes poked in it...

[ailblentyn]

"Inflation is what cause the Big Bang to go... BANG!"
This explanation sounds closer than ever to Penrose's idea that cosmic inflation = heat death of a (preceding) universe.

[philippejacquot]

Nice one Robert, great episode. keep em coming

[robertschlesinger]

Very interesting and worthwhile video.

[stefanblue]

One question : Why did not one of them get the Nobel Prize?

[hotrodsonulondon]

Creation is the key, something that stands out. God 🙏 lives in his own creation.

[davidhine]

The Hubble Constant is easily calculated from the following equation:- 2 X a Megaparsec X C, divided by Pi to the power of 21 = 71 K/S/MPS. This is known as "The Principle of Astrogeometry". The Hubble Constant is "fixed" at 71. There is no such thing as "dark energy".

[Niadrawings]

Could cosmology explain the nature of consciousness? Is consciousness beyond the physical world?

[cvsree]

This is more like closer to facts

Truth is lot more elusive and yet so immanent

[shiddy.]

10:30 a relatively short amount of time - what effect did time dilation have on this process?

[Scribe]

I'm just glad it's not about free will

[vellasdad]

Frequency of these commercials is inflating . i personally have never considered buying anything from any advertisement that has interrupted the videos i enjoy watching/listening to . wait . thats not true . fresh baked dispensary grabs my attention, however, im not going to get out of bed to drive to boulder just to by a joint at 2A.M . even if they were open .

[cole]

what part of space is expanding? the outer edge? or all space at once? if its all space at what size scale does that stop?

[mahmoudbader]

May anyone to tell what is the music name at the beginning
