Is time travel possible?

from Science with Sabine · host Sabine Hossenfelder

What does physics say about time travel? Surprisingly enough it doesn't just say it's impossible, it's more complicated than that. In this video I'll sort out what Einstein's general relativity and quantum mechanics tell us about time travel. And is MIT really building a time machine to find dark matter? We'll get to that. This video has a quiz which you can take here.
