Gravitational Ringing Unveils Neutron Star Mysteries ⚡ экспресс
Original: "Listening to the long ringdown: A novel way to pinpoint the EOS in neutron-star cores"
The fading gravitational echo from merged neutron stars can reveal the elasticity of matter in their interiors.

After two neutron stars collide, a vibrating lump of ultra-dense matter remains. Its gravitational ring—a fading ripple in space—gives away a secret: by how fast the spin fades, you can calculate how stiff the matter is at the core, where density is five times nuclear. This method will open a window into the world of the most extreme stuff for the first time.
🎯 Some neutron stars spin at 716 times per second—faster than a kitchen blender.
