Neutron Star Observed Creating Otherwise Impossible Form of Matter

Neutron star observed creating otherwise impossible form of matter "Neutron stars are the unimaginably dense remnants of collapsed giant stars. They get their name because the conditions inside are so fierce that atoms are smashed apart into a soup of protons, electrons, and, yes, neutrons. And now we have the first direct evidence that neutron stars are forming superfluids of neutrons - a totally bizarre state of matter that can't even be created in Earth laboratories.

A superfluid is sort of like a liquid, except its behavior can be very strange. Basically, a superfluid is where viscosity drops to zero and thermal conductivity becomes infinite, the upshot of which is the superfluid flows uncontrollably in all directions while maintaining the same temperature throughout. Even gravity is no longer a barrier for superfluids - it can flow right up the side of a beaker and escape. Superfluids essentially live in a world without friction."
