Dark Matter

What’s that dark, big, mysterious stuff in outer space? Good question, scientists aren’t sure either! But they think it might be a funky substance called dark matter. If you’ve heard of dark matter but don’t know what it is, make sure you check out this BrainPop movie. In it, Tim and Moby will tell you why astronomers think there’s something massive out in space that we can’t see. You’ll also learn a little bit about the history of how dark matter was discovered, as well as what scientists think it might be made of! It’s pretty spooky!
