Question

When a star goes from the main sequence to the red giant phase, it becomes larger rather than smaller. This is true because gravity is getting temporarily overpowered by
A) Antigravity
B) Electron Degeneracy
C) Energy of Fusion
D) Energy of Fission

Answer 1

I believe this is electron degeneracy, because the star is essentially having too many reactions too fast and collapses in on itself eventually.
