A swirling vortex in a glass of water can become an analogue of a cosmic catastrophe — the black hole bomb. Scientists discovered that with strong swirling, the hollow center of the vortex reflects waves, like the walls around a black hole, causing them to grow avalanche-like. This opens the way to desktop experiments to test gravity theories.
🎯 Tornadoes and waterspouts exactly replicate the structure of black holes: their empty center acts as a trap for waves — once they reflect, an avalanche begins.
