The fact that the math shows there is no internal contradiction shows that it isn't a *logical* issue whether an actual infinity exists or not.(February 14, 2018 at 10:27 am)Grandizer Wrote: Yes, so? Can you provide an abstract example of a married bachelor as well? You were saying earlier that "completed infinity" is a logical contradiction like "married bachelor". I gave you a logical example of "complete infinity"
So, when you said there was such a thing as completed infinity of events, you are talking about real objects. Your justification is that mathematics has a useful (on paper) abstract concept like considering all of the natural numbers--which cannot be counted--as one thing. You don't see the difference?
Still waiting for a link from someone.
Yes, math considers the collection of all counting numbers as a single That single thing has infinitely many elements. The fact that this does not lead to a contradiction is enough to show a 'completed infinity' is NOT the same as a 'married bachelor'.
And, once again, physics uses infinite time or space all the time to help in the description of the real world.
Again, we do not know if either space or time is *actually* infinite. It is possible they are. It is possible they are not. It isn't a question of *logic*, but one of evidence for which is actually the case. Currently, the best evidence points to a spatially infinite universe. Also, most quantum theories of gravity point to an infinite time into the past.
