Jaime Rudas replied to the thread Undergrad Euclidean geometry and gravity.Is that "flat plane" two-dimensional or three-dimensional?

Jaime Rudas replied to the thread Undergrad Before the Big Bang.Wouldn't it be better to say that they do not meet condition (b) because they have a past spacetime boundary?
-
Jaime Rudas replied to the thread Undergrad Before the Big Bang.Yes, that's why I said "remember."

In Hawking's "no boundary" model, the portion of the model "before" the initial time (which is shaped, heuristically, like a hemisphere...

Jaime Rudas replied to the thread Undergrad Before the Big Bang.Polaris? :wink:
-
I agree that that's the case but I'm not an expert.
-
One possibility, known as the Hartle-Hawking no boundary proposal, is that if you go backward in time towards the big bang, you reach a...

I believe the idea is that space-time was created by the Big Bang. No BB = no space and no time.
-
Jaime Rudas replied to the thread Undergrad Before the Big Bang.It seems to me that, according to these two hypotheses, time was created in the Big Bang. Which makes me realize that saying that time...
