What is currently thought to be the strongest material in the universe?

A neutron star is what is left after the explosion of a massive star which turns into a supernova. It is fundamentally the small leftover burnt out core of that explosion which is perhaps 20 kilometres wide, extremely dense and collapsing in on itself. The inner part of the star breakdowns so much that some of its protons and electrons are squeezed together to form more neutrons which is the reason for the name neutron star. The density part is key because neutron stars are so dense that a single teaspoon of them would weigh up to a billion tons. So, if you were to dig about a kilometre below a neutron star’s surface, what do you think you’ll find. This is something that has been simulated by new scientific findings.

The pressure inside a neutron star is so intense that the material inside comes together in rare patterns, many of which ambiguously look like pasta shapes, which is what they’re named after. These shapes were revealed via computer simulation, because such high pressures and the subsequent high densities are very hard to duplicate here on Earth. Previous works had already shown that the surface of a neutron star is tremendously strong, but these new simulations show that the nuclear bearing that lies beneath is even stronger.
