I posted a thing on youtube about what if you were at the very edge of the universe and could walk to the other side (I know it's not possible) but I wonder what would be there if you could? But people said there was no edge, I don't understand. I know youtube probably isn't the best place to get intelligent answers which is why I came here. Another thing that amazes me is how people on this tiny little earth, can actually predict or measure the size of the whole universe with instruments the size of probably a trillionth of an atom or less in comparison to the universe  |
We are used to living in our little world that has limits. Our brains are accustomed to thinking that way.
But growing up on a planet, with atmosphere and gravity... You know things fall down go boom.
You know there is such a thing as a vacuum.
Right?
Hmmm uh oh...
Maybe not. It's just that is how we are used to thinking of things.
The universe does not seem to have an "edge." Not like we are used to.
Think about traveling west. Go in a straight line. Using a hover-mobile. Eventually, you will wind up right back where you started from. Now- that's a poor analogy because it is still within the limits of what we are used to. The reason is because the Earth is a globe.. Well space is like that too. Only it isn't a globe. It just leads back onto itself.
