Some physicists have considered the possibility that dark matter might not exist - and that instead, it's our theories of gravity which are wrong. Today we take a deep dive into these theories of modified gravity.

Dark matter has eluded physicists for years - all we know is that it's some kind of matter that doesn't interact with light. Does that sound like a black hole to you?

Every time a particle of matter is made, a particle of antimatter is also made. So it seems like all matter ever created should have annihilated with antimatter, leaving behind an empty universe. But then... why is our universe filled with matter?
