When a star runs out of hydrogen to burn, it starts burning helium and so on until all of the fuel source is burned away into iron. My question is after a star has burned past its' main sequence and is burning helium, is the core temperature of the star lower? higher? the same?
It seems to me that the temperature would have to be higher in order to fuse these heavier elements.

I've heard and read some things about the photon belt, but none of it is conclusive. Some sources say that the extreme concentration of photon energy will disrupt all electrical devices on Earth and some sources say it will push Earth into an estheric (spelling?) dimension. Other sources say that it will take the Earth 2000 years to move through this belt and then other sources say that we have already entered the photon belt. Other sources are just ridiculous. To be honest, I still don't know what the photon belt is exactly and whether it holds any implications for life on Earth at all. How big is this belt and how did it form? How long will it last and has the Earth ever passed through it before? If so, how long does one cycle last? I need someone to really dumb this down for me; like a "Photon belt for dummies" book. No rocket science please.

If it is, what about the countless dust particles and nebulas? Also, if a spaceship explodes in space, how will the explosion look? Will there be fire and for how long considering that there is no oxygen in space. Will the explosion be without sound? Has any spaceships ever exploded in outer space?
