A closer look

The ultimate Italian dinner exists in the most hostile environment imaginable: the ultra-dense crust of a spinning neutron star. Crushed by gravity billions of times stronger than Earth's, atomic nuclei are squeezed so close together they deform into bizarre crystalline shapes resembling gnocchi, spaghetti, and lasagna. This nuclear pasta is officially the hardest material in the universe, requiring 10 billion times more force to break than terrestrial steel.
