@aoeuPrime You are right , the sun is not on fire. Fire needs oxygen in order to burn. But molten rock does not need a fire to produce heat, light and radioactive decay only gravity.

If gravity is producing heat then the law of conservation is wrong.

Till the death of the Sun I'm not sure if any humanity will still be alive on Earth.

Except there's not enough oxygen to start combustion. So no, not really.

It's pretty cool and all, but I wish they'd turned the sound on. Lots of cool explosions and stuff.

Well you can pull this definition of fire:

7. (noun) The elements necessary to start combustion.

Based on that definition I'd say we're allowed to use the word fire. ;-)
