Universe Quizzes, Questions & Answers

It’s a big, big universe out there, but for most of us our knowledge on the subject is vanishingly small. Sure, you’re probably familiar with our space-time origins in the Big Bang, and you may even know a little bit about the movement of galaxies and the omni-present cosmic background radiation filling all of know space. 

But do you know how much matter, dark matter, energy, and dark energy makes up our universe? How old is the universe – and could there be other universes besides our own out there? What do scientists mean when they say our universe may be “open” or “closed” or “flat”? If you’re feeling insignificant in the face of all that’s out there, take our quizzes and broaden your horizons a little!
