Why doesn't the Sun just burn up and fade away?

Question

If I told you that it is Boiling Neodynium, atomic number 60, Weight 144.24 would it be so hard to accept. This Hydrogen Theory just doesn't get it.
If neodynium boils at 840 degrees C. there is no known temperture known that accounts for evaporation, or is there?

Answer 1

It will...oh, it will.

Answer 2

It will, in about 5 billion years when the fuel is exhausted. Typically the solar fusion only reach the iron element, and then go into a super nova reaction, so Neodynium wouldn't be involved.

Answer 3

You misunderstand what a star is. Its not a fire - not a big ball of hydrogen gas burning like it would on Earth in some kind of fire.
The sun, like all stars, is a giant nuclear fusion reactor.

When the mass of a star gets to be enough (about 75 times the mass of Jupiter), the pressure of the weight of all that mass at the core generates enough heat to cause hydrogen to start to fuse into helium.
4 atoms of hydrogen fuse into one atom of helium - the small difference in mass that results is converted to energy according to Einstein's famous e = mc^2 equation.
This energy is what causes the sun to radiate heat, light, and other energy.

Answer 4

It is just burning up and fading away. The trouble is... there is so much of it, that it take billions of years to do the 'fading'.

As for the huge temperatures... nuclear fusion accounts for the massive energy and therefore massive temperatures found in the core and near the surface.

Answer 5

see water gets evaporated not hydrogen. There is no water on the sun to evaporate. Also the sun releases a amount of heat energy that just can't fade away.

Answer 6

Hi. In 'Star Trek' the writers would call that 'techo-babble'. Neodymium (the correct spelling) boils at 3074 C at which point it evaporates. Or you just decouple the phase transducer module and make tea with it.
