Since this degeneracy pressure does not leak away like ordinary pressure, the partially degenerate core helps to support the star and leads to a gradual collapse as the outer layers settle onto the stable core.

5. What evidence do we have that giant stars are really 100 – 1000 times larger than our Sun? a. Actually, we don’t have ANY photographic evidence because ALL stars appear as points of light for any size telescope - there is only stellar evolution theory to support this conclusion.
