When I offered my theory of a hyper-spherical universe, I was accused

universe had a start or beginning, that "time" must of been
characterized by zero volume.
Exactly the sort of thing Aristotle would have taken as a logical axiom.
My reasoning is that IF had non-zero volume, it must have begun
_earlier_; hence, this situation wasn't its start or beginning.
Look at the Hawking-Hartle no-boundary model. When does it start?
My prejudice, if that's what it is, is that the creation event, if
there was one, couldn't have "started" without some time-requiring
process.
Another reliance of an Aristotlean intuition. Did "start or beginning"
turn into "creation event"? Isn't "creation" just sneaking in the idea
of a process.
So, if there was something, rather than nothing at the beginning, the
time-requiring process must have began _earlier_, thus contradicting
the idea of a beginning with some thing already existing, say some
volume of space. The logic here is sort-of a proof by contradiction.
Whether you agree or not, what has this to do with Aristotle?
Because Aristotle (and other Greek philosophers) thought their intuition
could impose constraints on how nature can be, and called it "logic".
