“Before” the Big Bang is nonsense. It’s equivalent to saying “head north from the North Pole.”
very nice analogy. I’m stealing it.
I still think that means I have to up towards Polaris.
Evidence of god?
ZEROOOOO
Well, the equations that predict black holes also predict white holes, and the big bang is functionally equivalent to a white hole. And we have found black holes. So…seems like the most plausible explanation for the big bang is…it was a white hole. Still can’t extrapolate backwards for the same reasons, but there are at least implicit causes of white holes suggesting there was spacetime before the big bang.
Your universe is a derivative of another source of matter or energy. You are a derivative and there is nothing you can do about it.
Well you’re forgetting about the big unbang, which occurred just before the big bang and condensed all matter and energy into a tiny speck.
The hot big bang is basically just “let there be light” wrapped up in science words and don’t get me started on the period of rapid inflation. It’s incredible to me that the bedrock of modern physics is hand-waved away to get grad students focused back on either bigger nuclear plants and bombs or more qubits.
Fortunately the big bang isn’t actually a bedrock of anything outside of cosmology and can be entirely ignored by the rest of physics.
To my knowledge, we also have zero evidence that they didn’t exist. Nor have we ever observed matter/energy appearing out of
thin airvaccuum, so it seems unlikely to me.Well, we haven’t directly observed matter appearing spontaneously in a vacuum, but we have evidence to support it does happen
And to my knowledge there can’t be a before time.
Yeah, I suspect that the universe may expand and contract, so likely all the matter in the big bang came from it all being compressed from the previous cycle.
I also think all total matter gets distributed the same way each cycle, so I guess I think all matter that exists now is the same matter that has existed always.
I also think each cycle, everything happens the same way deterministically, even though it would be exciting to see if maybe events happen differently each cycle.
