Before the Big Bang 6: Can the Universe Create Itself?

Richard Gott , co author with Neil De Grasse Tyson of "Welcome to The Universe" argues the key to understanding the origin of the universe may be the concept of closed time like curves. These are solutions to Einstein's theory that may allow time travel into the past. in this film, Richard Gott of Princeton University explains the model he developed with LIxin Li . Gott explores the possibility of a closed time like curve forming in the early universe and how this might lead to the amazing property of the universe being able to create itself. Gott is one of the leading experts in time travel solution to Einstein’s equations and is author of the book “Time Travel In Einstein’s Universe”.
This film is part of a series of films exploring competing models of th early universe with the creators of those models. We have interviewed Stephen Hawking, Roger Penrose, Alan Guth and many other leaders of the field. To see other episodes , click on the link below:

How did existence itself come into existence. This thought genuinely gives me anxiety

[OmarCanada]

Finally! found something more complicated than my ex-gf

[uueaouaueaueau]

I like how at 10:40 the interviewer starts nodding like he has ANY idea what he's talking about.

[a.meireles.boxing]

Someone just clicked : "Start simulation"

[markpeterson]

A wonderful and profound lecture of immense intellectual interest. Thank you. Princeton’s Richard Gott is a great teacher.

The Universe went through a hell of a lot trouble to bring your eyeballs 👀 to watching this YouTube video.

[DadsCornerLew]

178% more confused after watching this than I was before.

[AussieDad]

I’m quite proud of myself. I lasted 15 minutes before i gave up hoping that I might understand at least something. I’m not even sure if the hat doesn’t go with the suit or the suit doesn’t go with the hat.

[VocalMabiMaple]

I'm learning astrophysics from a cowboy. I like that

[mrEofPlanetEarth]

This guy makes sense, but he sounds like a nut, hilarious.

[hugoa]

The universe big banged, became conscious, and then tried to figure out how it did it. What the fuck

[joalberici]

I've spent a lot of time in physics because it interests me but this is still way over my head! He had me until he started talking about vacuum states and then I had to whip out trusty Wikipedia. It excites me though, realizing how much more there is to learn

People can't still realize that time is not a thing, but a result.
We have matter, and matter in movement is what we call ''time''. Matter for itself can't be.
Only when it moves in any direction, generates the ilusion of ''time passing by'' and so then, existing, being.
Because it moves.

Stop the matter, and you ''stop'' time. That's hypothetical, you can't do that practically, you are matter in movement also. So no way to stop time and observe it disappear from the equation.
In theory yes, we are living in the same stop moment of the Big Bang, with the difference that matter moved a lot...but we're in same full stop, eternity, but because of matter in movement, we perceive it as ''time passing'', from back to the future (those two doesn't exist).

Time is not the speed of light itself. All matter can't move that fast. Only fotons can. But fotons are a part of all the matter.
Maybe I'm partially or fully wrong :)

Relativity with a Kentucky accent! Awesome!

[jsmcguireIII]

The universe created humans so it could experience self-awareness. I wonder if it has any regrets.

[tomschmidt]

I find your videos intriguing. I must admit I don't completely understand the implications of these pre-big bang hypothesis but I'm amazed scientists are able to postulate them given the bizarre nature of quantum mechanics. Gives me hope for humanity. Hopefully you will be able to create many more of these thought provoking videos.

[LividImp]

Listening to this guy is like if Gomer Pile got hit in the head and was suddenly a genius.

[rav]

13.19 - the question of first cause still exists. What put that system into place in the first place?

[onbored]

When I was in 10th grade I read his book "Time Travel in Einstein's Universe" (J. Richard Gott), and was absolutely blow away. It took me a few read throughs to really grasp it. I remember asking one of our physics teachers about it. I said "Hey, I'm kind of confused about these cosmic strings, I don't quite understand what these are exactly." and he just replied "You aren't supposed to" and walked away. Me and my friends just lost it laughing. He noped out of that conversation so fast. ahh.. good memories.

What goes into a black hole.. comes out as a new univers.. There never was a "big" bang, But a creation of a new black hole..
So If I´m right here, there are manny universes.. ;) Take care.. Greedings From Denmark ...
