Einstein believed that black holes didn't really exist. But they do: that much we know. We don't know much else about them.

"The singularity is the most mysterious and problematic part of a black hole. It's where our concepts of space and time literally no longer make sense." ...

The study explores a different solution to the same equations that normally describe gravity—both in Newtonian theory and in general relativity. These equations link mass with the gravitational ...

In 1994, Miguel Alcubierre was able to construct a valid solution to the equations of general ... turn the handle and you learn how gravity works. General relativity on its own doesn't tell ...
