RJG wrote: ↑June 9th, 2024, 6:54 pm The "beginning of time" is an obvious oxymoron (logical impossibility; X<X form). In the absence of time, there can be no "beginnings". If time exists, then logically it has always (permanently; infinitely) existed.

Mathematical objects simply are; beginning and end of variables are unintelligible in that sense.The existence of time that you speak of would merely consist of a mental concept, an experiential memory with as foundation a belief in time. Is that correct?
When sufficiently complex (as deemed by their adherents), internally consistent mathematical theories create mathematical-physical (logical) worlds that can be imagined to be, in a weak collective sense.
These worlds are purely hypothetical and are private to specialists for the most part.
That is, these worlds are not, and cannot possibly be actual in anyone's sense of actual. Therefore no-one lives in them.
There are other senses of exist that in no way correspond to the mathematical or physical versions of the word.
We generally imagine that we exist in one of these other senses, without closely examining what we might mean by exist.
I believe that it would be wrong to assign validity to the idea that that type of existence is assumptorial of nature (meaning: that it can be assumed for the purpose of communication). The 'existence of time' as communicated, isn't valid within the scope of 'the communicated'. When it comes down to it, it merely consists of a 'belief' (dogma), of which it could be said that that belief isn't a valid ground for the assertion 'existence'.
This is what Einstein might have meant: "Time does not exist — we invented it.". By saying this, he refers to time, but in the same time he denies its existence by placing it in the scope of 'belief' (dogma) and the subsequent idea that 'belief' is no ground for what is commonly perceived to be valid within the scope of existence.
