The aim of /v/Physics is to build a subverse frequented by physicists, scientists, and those with a passion for physics. Papers from physics journals (free or otherwise) are encouraged. Posts should be pertinent, meme-free, and generate a discussion about physics. Please report trolls and intentionally misleading comments.
At this early stage /v/physics is open to any physics related question or comment. Including physics homework problems, physics GRE problems or questions, or questions about jobs in physics.

Only halfway through the article. But I wanted to point out that the article has some very poor wording when describing a neutron star. The repulsive force is due to quantum degeneracy pressure. Basically, no particles are forced to occupy identical states. It is that contraction cannot proceed further because of the Pauli exclusion principle. They cannot occupy identical states, and thus the contraction halts.
Maybe nobody else found the wording poor. But it read to me as if they were saying that particles in neutron stars do occupy identical states. So I just thought that should be clarified.
