Borde-Guth-Vilenkin Theorem

[coolduude]

From what I know, this theorem states that the universe had a beginning and there must be a finite number of universes in a multiverse model (such as M-theory).

So is the Borde-Guth-Vilenkin Theorem true? (to your knowledge)

If there are atheists who object, what are objections?

There is a good explanation for this on the Magis Center for Reason and Faith:
magisreasonfaith.org/Magis_FactSheet.pdf
(scroll down to the discussion of the BGV theorem.)
As I understand it from that explanation and other resources, the BGV theorem says that (based on general relativity considerations) time must be finite in this and all universes for which “physically reasonable” laws obtain, so that implies a beginning.

An absolute beginning you mean? ‘God’ you could say?

An absolute beginning, yes. Where you take it from there is metaphysics and faith, not science.

Wow!! Very interesting article! That’ll keep me occupied for a few days thanks for sharing!

The theorem is correct; I would assume that the process of peer review would have already discovered an inaccuracy in the theorem already, if such a flaw existed in the Borde Guth Vilenkin theorem, since it was published in 2003. So far, there is no retraction.

The theorem basically states that for a spacetime with average net positive expansion over time, spacetime would be finite.

It is described here.

Ah! Big math words! :yikes: I’m not a mathematician
