what to proove

as another reason can be is that our universe is little round in shape it is getting flat and that's why we imagine that it its getting expanded

This won't be the reason of universe expanding but if we imagine that that like layers of Earth there are different layers in our universe as the explosions in our universe the matter gets spread through and that matters remains there and gets expanded...".Also universe is getting cooled and...

if we imagine there are some layers outside our universe in which some amount of matter can travel from our universe BUT not all matter, as that matter remains in, that's why our universe gets expand

i think that that matters come from explosion of stars etc...thats why it get expands
