- Enjoy A wonderful picture of space while I answer the question proposed perhaps by some in my last post!!!!
So, why isn't space infinite?
To answer this, let's translate it into numbers!! We know that numbers go on forever and ever and that infinity is a never ending number. So, infinity is numbers going up and up and up (because it never ends). Say you play a recording of the numbers going up and up and up. If we paused the recording the numbers will be at one exact value!! So infinity is just counting numbers. So, let's translate back. We know that the universe is expanding. If we played this expansion on a recording and paused it, the universe will have a value of diameter. So, space isn't infinite, but it is growing!!
