If you think you know how gravity works, you're probably wrong. While we can explain what it does, figuring out how has been a multi-decade long exercise in frustration and dead ends.

Theoretical physicists seem ready to move on from looking at dark matter as unknown particles we've yet to discover, and consider it a side-effect of gravity at cosmic scales.

The best way to understand the fabric of space and time might just involve a fifth state of matter and falling for a really long time...

CERN wants to investigate how antimatter falls by creating and dropping anti-hydrogen atoms, adding to our understanding of particle physics and its applications.

Black holes radiate virtually no energy, much less anything we'd consider heat. But that doesn't mean their innards aren't superheated to cosmic extremes...

Gravity can be tricky when you don't seem to understand how it works...

How to apply creationist logic to Newtonian physics.
