A Pulsar Near The Milky Way's Galactic Center Is A Perfect Set-up To Test General Relativity

Researchers with Breakthrough Listen and Columbia University have discovered a candidate millisecond pulsar in the Milky Way's center. If confirmed, it will allow unprecedented tests of Einstein's General Relativity. Pulsars are extraordinarily predictable, and are clock-like in their regularity. General Relativity says that signals from a pulsar near a supermassive black hole should be altered by the SMBH's mass, and this candidate offers a chance to test that.

The Milky Way's center is densely-packed with stars and there should be abundant pulsars there. But for some reason, we can't find them. New research presents a candidate pulsar in the GC. It's close enough to the Milky Way's supermassive black hole that it can test Einstein's General Relativity. But first, it has to be confirmed.
