An international team of astronomers has conducted a new test of Albert Einstein’s famous theory of general relativity (GR), finding that it works even in extreme gravitational environments, according to a study published in the journal Nature.

Since the great German physicist published his groundbreaking theory in 1915—which describes the nature of gravity—it has been tested numerous times by scientists around the world.
