They say: "Matter/energy cannot be created or destroyed."
Yet -- it's here.
So, folks like me ask: "Where did it come from?"
Their 'Answer': The Big Bang.
So folks like me ponder and then ask: "Oh. Well the stuff that was in the Big Bang that came spewing out so prolifically when it went Bang. Where did THAT stuff come from?"
They say: "It was always there BECAUSE it can't be created or destroyed."
Folks like me ponder and then ask: "Uh huh. But for 'it' to have 'always existed' aren't you saying that something can exist before it exists? For example, if there was a period in the Universe (in the nano instant of the Bang in the Big Bang) where there was no life, then life did not always exist. It got created. What created life? The stuff that came prior to life. Ok. But what created that? The precursors to that stuff. Ok. But what created THAT stuff? It was always there! But if it was always there then why wasn't life always there? Why do some things require creation but some things don't?"
The cosmological constant in the Einstein field equations allow for creation of matter/energy.
Cool. So the claim that matter/energy cannot be created or destroyed is not always true.
A lot follows from that.
