      Wow, what a great question! A short answer is- We don’t know!

      We can only see as far as light can travel in 13.4 Billion years (the age of our Universe), so it’s possible that the Universe goes on forever, and we can only see a big bubble inside that (called the Observable Universe). Some people have an idea that it’s maybe “infinite but bounded” which basically means if you started off in one direction, you’d eventually get back to where you started, like If you walked around the world.

      Fantastic question to which the answer is probably. This is exactly why you should look at being a scientist. Scientists are simply folk who wonder about life and the universe and seek to find answers.
