What the Image of the Milky Way’s Black Hole Really Shows

Web10. Black holes can be low density. Of all the weirdnesses about black holes, this one is the weirdest to me. As you might expect, the event horizon of a black hole gets bigger as the mass gets bigger. That’s because if you add mass, the gravity gets stronger, which means the event horizon will grow. WebBlack holes with different mass differ by the size of their event horizon (the point of no return); for a common black hole solution in general relativity (Schwarzschild black hole), the relationship is linear: $$ R \propto M $$ So that's the answer to your question: even if black holes of all masses all contain a singularity, heavier black holes have bigger event horizons. himos juhannus esiintyjät
