  • A new study found the first observational proof of a key prediction from Einstein’s theory of gravity regarding the existence of “plunging regions” around black holes.
  • It also exerts some of the strongest gravitational forces yet identified in the galaxy.
  • Einstein’s theory states that
    • Sufficiently close to a black hole it is impossible for particles to safely follow circular orbits.
    • Instead, they rapidly “plunge” toward the black hole at close to the speed of light – giving the plunging region its name.
