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 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.
-
@vicgrinberg just a joke - if we're all stardust then maybe our destiny is tied to the stars
@mahadevank The sentence about the stardust has nothing to do with any thought of destiny. The origin is scientist and science communicator Carl Sagan: https://www.planetary.org/articles/were-made-of-starstuff-what-does-that-mean
He talked about the building blocks of life, and the fascination of astro*N*omy when dust persons regard the dust in the cosmos and learn. About the cosmos, about life on Earth. -

@mahadevank @NatureMC jokes don't work super well online (if not clealy labelled or in conversatios with people one knows very well) - especially when there are enough ppl who post such things seriously.

@vicgrinberg @NatureMC yeah, i'm learning that lol
Sorry about all the confusion.

@mahadevank @NatureMC no worries, I'm just glad I don't have to deal with one of the folks who mean astrology seriously, it's always such a drag down.

@vicgrinberg @NatureMC yeah, i see why it drew such a strong reaction

@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
Or a scientific review article on this from the author of the plot: https://royalsocietypublishing.org/rsta/article/378/2180/20190301/41064/The-origin-of-the-elements-a-century-of

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

@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
