Thanks for the replies, this is one of the most active forums I've ever been on

it's just one of them mind boggling things, I have read that the universe is expanding and is a sort of oval shape, and people have said that there is no "outside" of the universe, but there must be surely? 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
