The Boundary Between Black Holes & Neutron Stars
When we detected the very first gravitational wave, a new window was opened to the mysteries of the universe. We knew we’d see things previously thought impossible. And we just did - an object on the boundary between neutron stars and...

Black Holes
We’ve covered a lot of incredible stuff, but this week we’re talking about the weirdest objects in space: BLACK HOLES. Stellar mass black holes form when a very massive star dies, and its core collapses. The core has to be more than...

How to Make Black Holes (Both Regular and Supermassive)
We've learned about the lifetime of stars, and we saw that very high mass stars will leave behind a black hole when they die. What else can we say about black holes? Is there any other way to make a black hole besides waiting for a huge...
