Question: What is the difference between everyone in the world being blind, and everyone and everything being invisible!?

Most of us are blind to x-rays!. But we can build instruments that can see x-rays for us!. But to x-rays, many things are invisible!. This is why they're useful to us - they can help us see through some things to reveal other things!.

So even if everyone in the world was blind, there is the possibility that we can overcome this limitation!. If everything was invisible, this possibility does not exist!. That is the difference!.Www@QuestionHome@Com
