@vicgrinberg wait up... The elements from Helium until Iron are created from nuclear fusion in the cores of stars as fuel to make their energy. Not in their explosions.
@nyx you are right, some element production happens in the star cores during normal fusion during the stars lifetime - but most actually happens in supernovae as the shocks heat up and shake through the outer layers: https://en.wikipedia.org/wiki/Supernova_nucleosynthesis

@wonka @nyx true, but mainly it's about elements being created during the actual supernova, see https://mastodon.social/@vicgrinberg/116832767432829053

We are all stardust.
The oxygen you breath? That comes from dying massive stars, ending their life in a supernova.
The iron in your blood? Some from massive stars dying, but mainly fron white dwarfs, the leftovers of dwarf stars like our own Sun, exploding.
Carbon, the basis of life? Mostly from dying low mass stars.
The gold ring on your finger? Mostly from merging neutron stars, leftovers from supernovae.
@vicgrinberg this makes me so happy!

@vicgrinberg just a joke - if we're all stardust then maybe our destiny is tied to the stars
@mahadevank @vicgrinberg What does it help if someone tells us complex things (we already knew for decades, btw) about stars breeding elements if they can't take a fucking obvious joke? Gazing at the stars is no excuse to lose touch with humanity.

@ax11 @mahadevank a joke is only obvious if there aren't a ton of people who mean it seriously.

@vicgrinberg @ax11 I totally understand the reactions, given that we live in a strange world where some people suddenly now believe that the earth is flat for no reason.

@vicgrinberg @mahadevank A joke is still a joke, even if YOU DON'T UNDERSTAND it. You're not all of mankind. And maybe we do not need you to explain JOKES to us. As an astrophysicist you're obvously out of your depth there. No sarcasm.

@mahadevank @vicgrinberg ...and it doesn't move either. No matter what the postgalileian wokes want us to believe.
If you find the sarcasm, you may keep it. -

If you find the sarcasm, you may keep it.@ax11 why are you even in this thread? Its between me and the OP. And we're both fine on this.
-
@vicgrinberg you sound like we should all believe in astrology
@mahadevank @vicgrinberg Yes! Better than thinking for ourselves, or *gasp* not needing PhDs to explain jokes to us and tell us when to laugh. Down with humor! Down with understanding! Authoritarism über alles!

@mahadevank Why are you on the internet? It was fine without you.

@vicgrinberg it’s a really interesting spread
-
@zauberlaus mergers are messy - the neutron stars are disrupted and quiet a lot of the material is being splashed around! It's in this flung out material that the r-process that leads to gold actually happens.

@vicgrinberg nice! thanks

@vicgrinberg @NatureMC yeah, i see why it drew such a strong reaction
-
@wonka @vicgrinberg yeah, that is true, but the infographic said that the explosion is the origin of those elements, whereas the elements are already formed in the star, they are just trapped. Idk, maybe it is a technicality but it sounded weird to me.

@nyx @wonka see my replies to you and to wonka: the explosion is indeed the origin! https://mastodon.social/@vicgrinberg/116832767432829053

@vicgrinberg Admittedly white dwarfs exploding usually require some other star to come along and add mass or merge with it.

I'm guessing the stardust that makes up human white skin must have come from a very special place in this universe where we occupy such a teeny-tiny part to make those white supremacists overcome their self-hatred.
