What is it that keeps a white dwarf from collapsing inward on itself?

Question

Quizplus · Accepted Answer

The white dwarf is kept from collapsing inward on itself due to electron degeneracy, which creates a pressure that counteracts gravity. In electron degeneracy, the electrons are so densely packed that they cannot occupy the same energy state as other electrons, creating a "quantum crowding" effect that compresses electrons into a smaller volume and creates a pressure that counteracts the force of gravity.
