Substituting can be a tricky art, especially when stars are involved. When massive stars explode, they can collapse into extremely dense — and mysterious — objects known as neutron stars. But neutron ...

Matching the neutron stars' cooling rates to their equation of state could help scientists figure out a quantum theory of gravity. When you purchase through links on our site, we may earn an affiliate ...
