What quantum mechanical pressure initially resists the collapse of the iron core before being overcome by gravity?
Answer
Electron degeneracy pressure
Initially, electron degeneracy pressure resists compression because electrons refuse to occupy the same space, but in massive stellar cores, gravity is so overpowering that it overcomes this resistance easily.
