      We don’t know how big it is because we cannot see the end. What we can do is measure how fast it is expanding and explore it with space shuttles. NASA should be able to answer a lot of questions about the universe

      Really, really big, but no-one really knows how large. What’s odd though is that we know it’s expanding, and we know how old it is. But we don’t know what the Universe is made of. Right now, the best guess is that only 5% of the Universe is made up of matter that we understand. The rest? Who knows? Or maybe the laws of physics are different for far away objects than for things that are nearby. Many people who are motivated to do physics research by wanting to answer these kind of questions.

      It’s a mystery. But safe to say, it’s MASSIVE.

      We can’t see the whole of universe but NASA has done lot of research and I am sure they should have approximate measurements of it…but its really really really huge…
