The Size, Age, and Scope of the Universe | Lawrence Krauss | Jordan B. Peterson

The full video:

In this clip, Jordan Peterson and Lawrence Krauss discuss the birth of the universe, how to define it and how new cosmological findings have helped to redefine scientific data and opinion.

I love how Lawrence has a gaming chair

[ChaseTheHeat]

Fun to listen to. To be blunt, because of what I believe, the moment I hear someone day that our Universe spontaneously started from nothing, credibility is gone. Still interesting

[torrespearls]

About 55 years ago I asked the teacher "where does the sky end?". His reply. "It doesn't". Quite rattled me. Seems that some have made it their life's work to find that out.

I will politely agree to disagree with Dr. Lawrence Krauss. I do enjoy hearing others points of view. This is how one learns & grows. 💙 Great discussion.

So something came from nothing that was interacted with by a powerful cosmic nothing. Feels like I’ve read about that concept somewhere.

[patrickturner]

He talks about the multi-verse like its not part of our universe. He says if we can't interact with it it shouldn't be considered part of our universe. However I many other talks I've heard him propose the milti-verse as the beginning of our universe. Like one universe coming out of another. If we can't have any causal interaction with any other universe why would someone think a universe could interact with another universe to create a universe?

Theoretical physics is a bit out of my depth. Dr. Krauss presents his material in a compelling manner, Just finished everything from nothing, ! Enjoyed it.
Thank You again JBP another gem.

More than four decades ago I had to take a drop fail in one of my classes because I had the chutzpan to ask a forbidden question to a professor
"can we make matter in a vacuum" then "Doesn't the theory of degradation/1st law of thermodynamics-entropy affect the plausibility of the theory of evolution?"

[aamr]

Kraua looks and sounds like a professor at Hogwarts School of Witchcraft and Wizardry

[makzmakz]

I can't help to feel that the guest sounds a bit arrogant when he says that the big bang is as sure as the earth is round.

[reggiestickleback]

Nobody asked that question in the past? Someone didn’t READ THE GREEKS or Church Fathers or SCHOLASTICS

[alexandre]

Interesting conversation. If the scale of the universe has taught us anything, is that us humans are poorly equipped to understand the size of the cosmos. The big bang clearly does not tell the whole story. It is almost evident to me that the observable universe is simply our corner of the cosmos, and that matter exists beyond our observable horizon. After all, if the big bang was all there is to it, the laws of gravity would mean a decrease to the rate of the expansion of the observable universe, while in fact, the rate of expansion increases. There is probably a lot more stuff surrounding us, eternities away from us. The big bang is likely a supernova like local event, which describes the origin of our cosmic neighborhood, but not the true origin of the so called "multi-verse". We are so insignificant, and know so little, yet some people claim to know that the universe was created or not.

So this video helped me get my words right on this, especially with the last analogy about a sphere around the observer. We shouldn't say THE universe, because the universe you're referring to could be moved and it would constitute different matter. We could be more specific and say OUR universe, to mean the universe surrounding the Earth. But if we were able to move to another galaxy far away that wouldn't make sense either - so to be more specific you can only you YOUR universe, which is unique to you, because only you can be in that space and time at once.

“The truth is that the materialistic conception, once it has been formed and spread abroad in one way or another, can serve to further reinforce the very ‘solidification’ of the world that in the first place made it possible; and all the consequences directly or indirectly derived from that conception, including the current notion of ‘ordinary life’, tend only toward this same end, for the general reactions of the cosmic environment do actually change according to the attitude adopted by man toward it. It can be said with truth that certain aspects of reality conceal themselves from anyone who looks upon reality from a profane and materialistic point of view, and they become inaccessible to his observation: this is not a more or less ‘picturesque’ manner of speaking, as some people might be tempted to think, but is the simple and direct statement of fact, just as it is fact that animals flee spontaneously and instinctively from the presence of anyone who envinces a hostile attitude towards them.”
-René Guénon, The Reign of Quantity and the Signs of the Times

[lawofliberty]

Hahahahahahaha, imagine theory as absolute truth.

[erikalicea]

I'd like to see Jordan Interview a young earth scientist.

[timangar]

I love this. Physics and psychology are both extremely interesting.

[Exodus.Pi]

Wait until you discover that Hebrew Cosmology is true.

[ldippel]

I'm no physicist but how is the expansion of space irrelevant to the conversation?

[PetarStamenkovic]

I can't believe that he is still insisting using the word play where nothing means- all the laws of our universe with the quantum understanding of nothing. You just need God- ordered universe with clearly defined laws and then you can make the universe out of "nothing".

You're just saying God can create the universe, but you're using the word "nothing" - that does not mean- not a thing- absence of anything.

I like this example to understand the word nothing: "Nothing stopped Nazi advancement." So, what stopped the advancement? Nothing. Does that mean that the advancement stopped? No! There wasn't a thing to stop it. There wasn't something called "nothing" that stopped it.
