Usually, the champions of compactness are black holes. But in a new theory of gravity, neutron stars could compress even further without collapsing. Quantum corrections to gravity make them stable, and they can emit gravitational waves. This means there could be objects hiding in space that we never suspected before.
🎯 If a sugar cube were made of neutron star stuff, it would weigh as much as Mount Everest.
🎬 In science fiction, super-dense “neutronium” is a favorite material for impenetrable armor, like in Star Trek.
