Alan Guth - How Did Our Universe Begin?

[Caligula]

Alan continues to be one of my favorite guests on this show. Remarkable man.

Having investigated this question very carefully, I have come to a conclusion.

[kimsahl]

Universe begin after an Universe-potential.

If you have watched a few inch column of clear water at the bottom of a pot just at the beginning of boiling on top of the stove, then you have witnessed what resembles the creation of multiverse in the form of bubbles that expand, burst, and give birth (space) to bigger and hotter multiverse (bubbles) to develop. The process that seems to have never started and never ends as long as the heat intensity does not destroy their formation.

I'm surprised with the low view figures.
It's Alan Guth. Genius

[meesalikeu]

as always, doc alan guth gets right to it in a clear and succinct way. a lesson here is that hey you outliers are important. 😅

If there is a multiverse, then it seems possible that we simply live in one of the universes in which there is more matter than anti-matter. Perhaps in other universes, the balance is different. In other words, the preponderance of matter over anti-matter cannot be derived from first principles but instead results from some mysterious initial condition which varies in some way from one universe to the next.

Amazing. We are here because of uncertainty.

An uncertainty in the fundamental mechanics of the quantum realm. If there had not been this uncertainty, the universe would have expanded in such perfect homogeneity that not a single fluctuation would have caused the gravitational imbalances needed for particles to attract one another, and subsequently "cascade" into the large scale structures of our universe (galactic filaments).

Could one have asked for a more succinct rebuttal to the concept of an intentional being behind our creation? We are here because of the Heisenberg uncertainty principle, and the Evolution by natural selection which followed it. Without, this universe, as I understand it, would be a sea of quarks, with no more or less meaning than our universe save the forces which precede it's very formation.

Ill defined as theism already is, could one argue that an intentional, personal, loving "God" created us through uncertainty? Sure, with a small side of hubris.

[Boulos-cbun]

We are nothing...nothing is all there ever was, nothing is all there ever is, nothing is all there ever will be.

[AtheistExpert]

just wait in 30 years we will be traveling to other universes with warp speed and looking back like wow, we sure were stupid.

[steveperry]

so to me as a rank amateur would you say that at or just before the begining were there any elements present like hydrogen or helium or just atoms or the parts of atoms? thnx steve

[cryptoroughcuts]

see, he said it, the earth is FLAT boiz

[SushilKumar-mptg]

he exactly looks like the Kind of scientist i would believe Blindly

[jamesruscheinski]

Did gravity come about as universe cool from inflation? What led to conditions in which gravity could start?

[Robusti]

First of "all" ; The universe has no absolute beginning as absolutely nothing comes out from nothing. One key components for this widely misunderstood conception of beginning is a realization that we can not extract any information beyond Big Bang and that validates our conception of absolute beginning. Not a logical conclusion, but a pleasant one, that feeds our hubris etc. "makes me feel a little bit special..". Just quarks without understanding what is the thrue/fundamental nature of matter. For ex. the absurdities concerning elementary particles such as: How can a particle which doesn't consist of anything but itself send & receive any information i.e. have any kind of formation, what is the density of a particle that consist only of itself, what is the shape of this assumed particle, as it must be 3D? "There must be a ultimate beginning" even there can not be.

[williamhatfield]

The Universe didn’t begin and there is absolutely no reason why it should have. As a corollary it won’t end either due to its entropy being constant.

[wayne]

Creation began by something in the Night

[danielfahrenheit]

Another question would be when will some kind of brain chip  come out so we can understand the mathematics of this stuff.

[HighPokerChessPL]

HOW MANY TIMES DO I HAVE TO SAY :: NOTHING IS REAL. BOTH REALITY. & A THINGABLE NOTHING.

[OldEnoughToBeYourFather]

In the beginning God created the heavens and the earth.
