Is it because of the gravity? If it is gravity why is the star luminous? If gravity is pulling the light, why isn't it a black hole already?
Please no rude answers, thanks!

No, not gravity. It is because the star is so big, any photon emitted at the core will bump into an atom on the way, and will get absorbed and re-emitted a few nanosecond later. But then, because of the pressure, the next atom is right besides, and the photon gets absorbed again. And again. And again. It is like a maze in there, and the photons do not always get emitted towards the surface, they can back up towards the center. And it takes an awful amount of time for a photon to finally emerge.

My view is that Vincent G is dead-on accurate.

with light being the fastest thing known to mankind, the only reasonable answer would be the distance traveled. light is anti-gravity
