(Big Bang Theory): General relativity (GR) is true, sufficiently accurately describing the full birth-growth of space. Consider three evidences:
• …General relativity makes accurate predictions.
• …Space in fact did expand from a hot-dense space.
• …Other evidences indicate: Physical reality (spacetime) began to exist, growing from a singularity.
This is relevant because “FLRW models with ordinary matter have a singularity at a finite time in the past.” [Christopher Smeenk, “Philosophy of Cosmology,” in Batterman (ed.), The Oxford Handbook of Philosophy of Physics (Oxford, 2013), 612.]1
•…Space has an early quantum era (not FLRW); GR won’t apply.
•…Space is not isotropic & homogenous.2
(BGV Theorem): Any Universe eternally inflating/expanding on average requires infinitely-fast travel Right?
• …consider Vilenkin's spacetraveler proof/illustration
So? Couldn’t it simply be that… [All forthcoming]
•…Space contracts on average
•…Because of an infinite contraction phase
•…Space is static on average
•…Because of infinite cycling
•…Because of an infinite contraction phase (during time-reversal)
A beginningless universe (or multiverse) model is true. This is relevant because the Standard Big Bang model under review here is not a past eternal model.
Singularity-expansions (e.g. The Big Bang) aren’t events. After all, “An event takes place within a space-time context. But the Big Bang has no space-time context; there is neither time prior to the Big Bang nor a space in which the Big Bang occurs.” (SEP).
