Like fossil fuels come from organic matter that grew because of the sun. Is there any form of energy on that cannot be traced back to the sun in some way?

    If main sequence stars were candles, supernova would be a nuclear bomb. Elements heavier than iron are only produced in events that are so energetic, the luminosity can exceed that of the entire galaxy they are in. What was a star becomes a neutron star or black hole afrer the supernova. Main sequence stars do not produce heavy elements until they die.

    So if you want to say that radionucleotides come from stars, I won’t play semantics police, but that is reductive to the point of missing out on how incredibly unique supernovae are as a stellar phenomenon.

      That’s so rad actually. Thank you for enlightening me. Isn’t that amazing that the elements on our planet came from those events
