      We don’t really know. We can see out to about 46 billion light years, but we can’t see beyond that. We think it continues on past that we’re fairly sure, but whether it ends we don’t know. Some scientists think it does, some don’t. It’s a hard think to prove.

      That’s a tricky one, great question! All we really know is the Univwrse began with the Big Bang and it has been expanding (into nothingness) ever since. The Universe is 13.8 billion years old’

      The Universe is undergoing accelerated expansion, meaning that things (mostly galaxies) are moving away from each other faster and faster. This is mostly likely to continue for ever! But we can’t see beyond our “observable” Universe so we think its expanding into nothing and has no boundary but a few theorisations believe in other things like multiverse, where at the edge of every universe is another one! not sure how that can ever be proved though!
