Is the Instantaneous Expansion of Space-Time Possible?

Given that the expansion takes place "in nothing".

Given that all space-time exists all of the time. (past/present/future)

If the ultimate fate of the Universe is that it collapses back in upon itself.

Shouldn't a singularity of space-time occur instantaneously?

After all, all time existed in the "first instant" too.

Would this not then produce a singularity of space-time, within which the flow of time is specific to the "observer"?

Hello and :welcome: !

Given that the expansion takes place "in nothing".
This is already confusing, as you probably associate empty space with that "nothing". There is no nothing.
Given that all space-time exists all of the time. (past/present/future)
Again misleading. It is as if you said: Given that all volume exists all of the length. (?)
If the ultimate fate of the Universe is that it collapses back in upon itself.
If ... then ...?
Shouldn't a singularity of space-time occur instantaneously?
Apart from the fact that these terms don't make sense in this ordering, who said it didn't (for whatever you meant)?
After all, all time existed in the "first instant" too.
Recursion. "first instance" already requires time.
Would this not then produce a singularity of space-time, within which the flow of time is specific to the "observer"?
I'm afraid your question is too vague and inaccurate to be answerable. You should read a book on special relativity before you start to "philosophy" about singularities. You could also do a forum search for "shape of the universe" or similar to find what already has been said on PF.

As this thread lacks a reasonable base, it is closed.
