Is the concept of infinity practical or just theoretical?

Question

Is the concept of infinity practical or just theoretical?

In: Mathematics

Answer 1

We do not know. There are different schools of mathematical philosophy concerning this topic with some of them believing that infinity does not exist.
That’s difference between ‘actual infinity’ and ‘potential infinity’.

While it might seem weird that some mathematicians working with infinite stuff does not believe in existence of infinity, the point is that it does not matter for any application whether infinity exists or whether it is just theoretical.
