As I said before, between the point 1 and 0 there are inifinitely many points, in fact uncountably infinitely many of them, but there are still the edges of the series of points (0 and 1), as well as a center to this segment (0.5), even though the number of points is infinite
Also, in
Cartesian coordinate system, all the axes (that can be in any number of dimensions, including higher dimensions) meet at a central point known as the origin, even though all axes go off to infinity in either sides. That once again proves that something Infinite can certainly have a center
As I said, Supertasks are examples of Infinite series of events that can be completed in a finite time, thus technically "ending" despite being infinite. In fact, Supertasks are applications of Infinite series from math. For example: Imagine you walk one kilometer, and each time you walk half of the remaining distance, you complete a step. As you cross, you'll complete more and more stages in a faster rate, but as we know (and was proven by mathmaticians) that 1/2 + 1/4+ 1/8 +... = 1, meaning you complete infinite steps in a finite time
