world of weird things podcast: how do you solve a problem like dark matter?

Cosmologists have been trying to figure out what dark matter is made of for decades and getting nowhere. And now, some are wondering if dark matter is just an illusion created by gravity.

why gravity is the force you think you understand, but actually don’t

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.

there may not be dark matter or energy, just gravity. we just don’t know how.

there may not be dark matter or energy, just gravity. we just don’t know how.

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.

how studying falling antimatter can eventually help us treat cancer

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

how hot could it get inside a black hole?

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...
