Black Holes Simulated in a Tank of Water Reveals “Backreaction” for the First Time – Universe Today
Water simulations that small gravitational waves near a black hole can significantly change the black hole’s behavior.
It’s hard to make a black hole in the lab. You have to gather up a bunch of mass, squeeze it until it gravitationally collapses on itself, work, work, work. It’s so hard to do that we’ve never done it. We can, however, make a simulated black hole using a tank of water, and it can tell us interesting things about how black holes work.
Water simulations of black holes are possible because the mathematics that describes the behavior of water is similar to the mathematics that describes the behavior…
