comment How can anything be hotter than the Sun?
+1 for mentioning the temperature of the sun's surface rather than core.

@all thanks guys - lots to think about here.

And in the case of fusion: we have tritium + deuterium fusing to make helium + a neutron + energy. Doesn't that leave us with still 3 neutrons and 2 protons at the end, ie: the same at the start?

So, in the case of splitting a plutonium atom, what gets lost? Presumably electrons are not touched. So, do we lose protons or neutrons? That would determine the elements produced. I assume the resultant atoms would be in plasma form given the temperatures involved.

@Georg - I did look at the diagram but I have not done physics since high school. I would rate myself a poor amateur at best with spotty knowledge. The structure of a diamond remains stable once the temperature/pressure is removed but this is clearly not the case with, say, metallic hydrogen. I'll look further into this.

cool. is the ϵ structure of iron stable once pressure is removed?
