Thinking about infinity

[robvalue]

Oh, I see what you mean. So yes, it would appear to be a logical possibility, as far as I can tell.

To review what I said about dividing something up infinitely... that too would appear to be a logical possibility. But this is something we would potentially have more information on, so those well versed in QM may have a reasonable prediction as to whether it is possible based on what we observe. (Something about "stable wave formations" comes to mind.) However, there's always the chance that this prediction is wrong, and that we're just using the wrong techniques or tools. Certainty is not the job of science.

As to how a finite object can be made up of infinitely many parts, that is covered all the time (at least abstractly) in mathematics by such processes as summing an infinite geometric series, or performing integration to calculate the area under a curve.

I'm not convinced science could ever rule either of these out categorically (infinite past / subdivision)... but it may well be that there is enough evidence (now, or on the future) to make a pretty sensible estimate.

Another important point: even if time was finite in this reality, that doesn't stop time being infinite in another reality; and perhaps it could be viewed as "the past" if our reality actually came from it in some sense. I don't know if that has any bearing on your question.
