Is there such a thing as infinity? Sure we can think of it as repeating numbers that will never end, but does it exist? If you were to solve a logarithmic equation, there are certain restrictions that you would make in the beginning. When we've solved the equation we find two answers. Only one of them is right; the other, although it can be conceived, does not exist because it does not meet the restrictions.
So I'm not sure if infinity is real, it could very well be.
Eternity on the other hand, I think to exist.
In what sense? Nothing is perfect.
I don't know what that is
I believe that we must know our limits. That doesn't mean that difficult things can not be overcome, but just that we can't be everything.
