Ruling out an expanding universe with conventional proofs

Hi, Starlite.Welcome to EvC! That's an interesting way of phrasing the question. See, the point Cat Sci was making is that the math works perfectly fine for explaining most things in the universe, but something in the formula goes to infinity when you try to apply it to the moments immediately after the Big Bang.That's what is meant by the word 'singularity': it just describes the math returning an answer of 'undefined' in a specific situation. It isn't an event that happened or a thing that made something else happen: it's just a mathematical asymptote. And that's exactly what the Big Bang Theory predicts the math will do if you try to input time = 0.

Hi, Starlite. It's not my line or my math. You're the one who brought up the singularity, and I'm just explaining what it is. As has already been explained, a singularity is just an "undefined" result in a mathematical formula. That's it.Since you're thinking in terms of 'what if' questions, you can think of the singularity as the answer to a nonsensical "what if" question. The answers to----- Arrogance and ignorance should never be mixed like this. If the only thing you're getting out of this is that you should pick different words when talking, then you haven't assimilated with Cat Sci is saying.Your questions simply don't make sense. For example, this one: I can't even tell what you think you're asking here. It seems like you've got some rather glaring misconceptions about how the reasoning process has played out. First of all, you've got the cause -> effect relationship backwards. The reasoning doesn't go "singularity -> therefore expanding universe." Rather, the reasoning goes, "expanding universe > therefore Big Bang." The singularity is just a result of the formulas giving wonky answers to nonsensical questions.In a little more detail, there is evidence that the universe is expanding. I'm not a physicist, but I know that at least some of the evidence has to do with light from distant sources (such as stars and galaxies) being redshifted, which is the same concept as the Doppler effect when a car drives by on the road.Since we have reason to think the universe is expanding, we can combine that with the known laws of physics to model what the universe would have looked like at different points in time.
At some points in time, the math suggests a universe of hot, quark-gluon plasma.
At other points in time, it suggests "swirling clouds of hydrogen mingled with plasma," or "atoms and planets and galaxies," etc.
And, at one particular point in time, the math only says, "undefined."
