I had a question, I was reading Stephen Hawhings book on the universe and black holes. I came on to a segment which I could not understand. In the book, it says that when a star runs out of its fuel and starts collapsing: "the matter particles get very near each other, and so according to the Pauli exclusion principle, they must have very different velocities. This makes them move away from each other and therefore makes the star expand"
I don't understand why the difference in velocities of particles would make then repell each other.
