OT - Physics Question on Anti-Matter

[Renegade 13]

Suicide Junkie said:
Everything around here except nuclear power comes from the sun. Fission power comes from ancient supernovae.
And both those come from the hydrogen the universe had as far back as we can see.

Not quite true. Geothermal energy neither comes from the sun nor nuclear fission; it's generated by the decay of natural radioactive materials like potassium, thorium and uranium. Tidal forces also play a role.

That's still supernovae residue, with the same ultimate source.

There is a modest amount of heat available from the formation and gravitational compaction of failed-stars and large planets. But again, that was all there in the potential energy of the starting material.
