Decaying nuclei is from supernova, but the rocks that formed the solar system and Earth? I’m not sure they can pinpoint an origin. I think atoms of a rock have different origins and at some point, they combined to form the rock, so that’s also an origin. To be verified.
The molten core is hot because a whole lot of rocks crashed into each other. Also, nuclear decay.
Well… those are remnants of a supernova aren’t they? So the velocities to have meaningful impacts came from a sun?
Definitely not what I was thinking or trying to say though, and not our sun, but kinda still all the energy comes from at least, a sun.
