Well, although infinity is very very large, it still resides in a finite universe.
If for example we are to give a name to each zero that we add next to 1, there will come a time when we will run out of words. If we are to write these zeroes down, there will hypothetically come a time when there will be no more space in the universe to write it without erasing the previous entries and losing significance. And even though that number is very very large, it would still be finite and bounded in our reality. Therefore, should infinity be substituted by a extremely large finite number in our calculations? Like Planck's length perhaps? Even calculations involving infinity limits are solved by substituting ever increasing large number. So why don't we just substitute Planck's length so that 1.616252(81)×10−35 would have some significance.
I mean, we do round-off or up numbers. Why can't we put a 'hypothetical boundary or limit' in infinity in order to simplify calculations and actually have a number to use.
