View Full Version : Bizarre Matter Found in a Neutron Star

SUMMARY: Scientists have theorized that the inside of a neutron star - the remnant from a star that has collapsed under its own gravity - is a special place where the laws of physics begin to break down; atoms are squeezed so tightly by gravity that all protons and electrons are crushed into neutrons which swirl around like a liquid, but without friction (called a superfluid). This theory has gotten some confirmation according to new research from NASA which observed neutron star EXO 0748-676, located 30,000 light years away. Using various instruments, NASA scientists determined that it's approximately 11.5 km (7 miles) in diameter, and contains 1.75 solar masses. With this much mass packed into a small area, the observations match the theory that neutron stars exist in this superfluidic state, but without being crushed further.
