I think that all the elements present in the solar system that are heavier than hydrogen were made by previous stars and elements heavier that iron (or carbon I forget) were necessary made by stars that went supernova.
It would be very surprising if all these stars were not surrounded by rocky planets who themselves had volcanism and thus a process of rock creation.
- hughesjj 3y agoTechnically speaking big bang nucleosynthesis/baryogensis produced elements as heavy as lithium with some abundance, but yeah still dominated by hydrogen (and whatever other exotic non-baryonic .... stuff is out there) - https://en.wikipedia.org/wiki/Baryogenesis https://en.wikipedia.org/wiki/Baryogenesis - https://en.wikipedia.org/wiki/Big_Bang_nucleosynthesis https://en.wikipedia.org/wiki/Big_Bang_nucleosynthesis Also, this is a great image showing the proportions of elements based on source https://en.wikipedia.org/wiki/Chemical_element#/media/File:Nucleosynthesis_periodic_table.svg https://en.wikipedia.org/wiki/Chemical_element#/media/File:N...
- Mistletoe 3y agoThat’s one of the cooler charts I’ve ever seen thanks for sharing. It’s wild that elements from merging neutron stars like iridium and uranium could even find us here. Sends home how old the universe is.
- irrational 3y agoFind us here? Our solar system was created far far away from here. All the stuff that makes up our solar system was created by far older stars that long ago exploded and threw their material into space. Eventually some of that material coalesced into our Galaxy and our sun and planets.
- brabel 3y agoSo neutron stars collisions are actually responsible for a huge chunk of the elements in the periodic table!? Mind blowing. How did they end up on the solar system after that? What we've got is just the material ejected when such cataclysmic collisions happen?
- Ixiaus 3y agoDo you have any books you could recommend on this subject?
- r2_pilot 3y agoIt's not the sole focus of the book, but I recall "A Universe From Nothing" by Lawrence Krauss mentioning it a couple of times, particularly in the case that only that set of elements in exactly those proportions leads to the Big Bang as the primary theory of how it all began.
- artemavv 3y ago"The Story of Earth: The First 4.5 Billion Years, from Stardust to Living Planet" by Robert M. Hazen has a chapter about genesis of elements ( big bang, star formation, supernovae, planet formation, etc).
