Define a raindrop as an object which plunges radially toward a black hole from rest at infinity. In Schwarzschild coordinates, the velocity of a raindrop is given by • The speed tends to 0 as r approaches the event horizon. The raindrop appears to have slowed as it gets nearer the event horizon and halted at the event horizon as measured by the bookkeeper. Indeed, an observer outside the event horizon would see the raindrop plunges slo… WebMay 9, 2024 · Allvar Gullstrand is a puzzle to a student of general relativity.
