If not, is it basically “something” expanding into “nothing”? Or it a foolish question as the universe is all there is? Or is our universe expanding and therefore “muscling” space from other “bubble” universes?
Here’s a question to ponder, if the Universe is expanding at the speed of light, how is the Adromedia Galaxy on a collision course with the the Milky Way Galaxy? Shouldn’t we be traveling at the spee of light ??????
