Question
This phenomenon prevents the total collapse of objects under the Chandrasekhar limit, for 10 points each:
[10m] Name this quantum effect which “pushes” apart particles that would otherwise overlap. The force from this phenomenon is enough to counteract gravity in white dwarves.
ANSWER: electron degeneracy pressure [accept but DO NOT REVEAL Pauli exclusion principle]
[10e] Degeneracy pressure arises due to this Austrian physicist’s namesake “exclusion principle” which prevents fermions from occupying the same quantum state.
ANSWER: Wolfgang Ernst Pauli
[10h] Degeneracy pressure breaks down at high temperatures, so white dwarves cool off by emitting these particles via the direct Urca process.
ANSWER: neutrinos [accept anti-neutrinos]
