What does the Universe expand into?
- oblomovshchina 8y agoNothing. The concept seems foreign because we're always in something, but there is definitionally nothing the Universe can expand into. If it's easier to conceptualize, just think of 'expansion' as a short way of saying 'distances are getting longer'.
- fareesh 8y agoSo does it mean that everything in the Universe is getting bigger but since everything is getting bigger we don't know it because relative sizes are the same?
