Here's a question from listener David:

Can we be certain that black holes still exist?

What's the evidence?

Yes.

For many years.the Max Planck Institute has been observing massive stars at the center of the Milky Way galaxy using infra-red telescopes  They have observed long enough to plot the course of a number of bright stars orbiting the supermassive black hole at the center of our galaxy, and this has allowed a quite accurate measure of its mass.
See: https://www.mpe.mpg.de/6590570/Stellar-Orbits

Recent work has even shown that one of these stars, S2, is showing gravitational precession, as predicted by the general theory of relativity:
