### The Infinity Problem

I got stuck in thinking the infinity.
I thought like this:
Let infinity be x

2x=2 infinity
The main problem is:There isn't 2 times infinity!
How can it be proven?

Hi;

Welcome to the forum.

I think most of that was established by Cantor and the mathematicians that followed. For one thing infinity is not a number, it is a concept. The rules of arithmetic do not apply.

In mathematics, you don't understand things. You just get used to them.
I have the result, but I do not yet know how to get it.
All physicists, and a good many quite respectable mathematicians are contemptuous about proof.

infinity is like /dev/null
Whatever you write or add to it it still remains /dev/null
