When a massive star dies and collapses into a supernova, a neutron star is born — a city-sized sphere with the Sun's mass. Its matter is so compressed that a teaspoon weighs more than Mount Everest. Physicists are trying to learn the "recipe" of this matter — the equation of state that explains how matter behaves under extreme pressure. The key is gravitational waves, ripples in spacetime from the collapse itself. It's like guessing the metal of a bell from its ring. New simulations have proven: even with realistic detector noise and uncertain explosion timing, artificial intelligence can flawlessly distinguish different recipes.
This hearing brings us closer to deciphering signals from real supernovae and uncovering the inner secrets of neutron stars.
Gravitational wave detectors are so sensitive they can pick up mirror movements ten thousand times smaller than an atomic nucleus.
Sci-fi authors have long imagined neutron stars inhabited by sentient crystals; now science is listening in to hear if quark soup hides within.
