The 0 is a real number, even when we count the 0 is part of the natural.

count is the assignment one to one of the objects starting with 1. But why start with 1 if the first number is 0?

We shouldn't take anything for granted. There are recent studies that show that the void is not as empty as we were told. I recommend the works of "nassim haramein".

Finally recently I saw a video where a group was about to check that the decimals of pi were wrong, I saw it in a video in Spanish.
