Supernova nucleosynthesis is STILL the accepted theory. Supernovae are common enough (about 1 per century) in galaxies to explain cosmic abundances we see. Neutron star mergers would be incredibly rare, so that's just simply NOT a viable model.

Is this a good reference for the neuron star merger nucleosynthesis theory arxiv.org/abs/1710.02142?

[@laura-ann.0726]

Prior to seeing this video, I had not previously heard that the theory of formation of elements heavier than Iron, had shifted from the Supernovae model to Neutron star merger. Is this a very new finding? For me, this is kind of a big paradigm shift. I'm 65 years old, and have assumed that the Supernova model of heavy element synthesis was firmly established since I was fist taught about in high school 50, years ago. Wow! Thank you!

Thanks a lot Sabine! I particularly enjoyed this video since I learned something new for me. So far I also thought that r-process happen in supernovae only. Didn't think about mergers of neutron stars, probably because I thought that gravitation is so strong that such merger directly lead to formation of a black hole and no matter comes out, may be only some light, neutrino and gravitational waves. Seem I was wrong. But anyway, please keep making such videos, I really enjoy them!

[@marklawes1859]

Aren't neutron stars stars then?

[@eljcd]

well, until recently, we couldn't see the light of a NS merger, so we didn't know what stuff was released in the collision. Now, with LIGO and other detectors of GW, it is possible locate the place in the sky where a merger happened, point a telescope there and get a spectre of light. This is gonna be a hot area of research from now on.

[@karlsjostedt8415]

All that exists is pure energy. Anything that has mass or seems solid is just energy held in a stable harmonic. If it seems solid then spinning energy is making magnetic fields that push on the magnetic fields of other atoms. There is no chunky thing called a proton or electron, just vibrations of energy that can seem like chunks when there is a huge amount of energy locked into a tiny harmonic configuration. The energy of the vacuum is probably the source of all energetic movements, and during the concentrated expansion we call the big bang, a lot of particles were created as the energy levels calmed down after the initial burst...

Thank you Sabine, for updating my knowledge about how the heavier elements came into existence. Up to this point, I thought supernovae created all the heavier elements out of hydrogen and helium. Now that theory has been challenged by the newer hypothesis of merging neutron stars creating those heavier elements. This is the best thing about modern western physics, which is the ability to correct the incorrect theories and blunders with newer and more accurate theories and hypothesis'.

Just a typical German pronunciation mistake made by pronouncing things the way you write them. I also do that quite often.

[@Taleb1160]

That’s is correct way to say it. The English language suffers from many inconsistencies, so don’t assume the English pronunciation is correct. For example the English word blood is pronounced as “Blud” as apposed to “blewed” as it should be pronounced, like some folks who pronounce it that way and we tend to laugh at them. not to mention if we follow that rule the we should pronounce the word wood as “wud “, but here Here we get it right 🙄. In English we also wrongly pronounce draft, draught the same way, etc the reason for all this is that many words in the English language were brought in from other languages. After all English is originally a Germanic dialect offshoot. Later developed further with many French, Arabic and other Latin influences. That’s why English is so inconsistent with pronunciation in comparison to most other languages on the planet. So “eyeron” it is 😅

[@elfenbeinturm-media]

@@Taleb1160 There is a great channel called "Langfocus" (a Canadian who who is a languages expert), who made a video about that; the main reason does not seem to be that English has a lot of "foreign" words in it - all languages have that. The main reason seems to be that, other than in French oder German or Swedish, the English language never was reformed in an efficient way, cleaning up inconsistencies.

[@michaelprozonic]

I have an unusual visual defect in which the first letter(s) of a word are sometimes replaced with different letters to form a different word so when i read the title of this video, I thought it was “Where do MOMS come from?” I thought the answer was pretty simple and didn’t require advanced physics to understand it

[@madallas_mons]

Neutrons have slightly more mass and energy than protons. After some time neutrons emit various quanta of energy in the form of smaller particles and thus lose mass and energy to become protons which are far, farrrrrr more stable and take far longer to decay further

[@-_Nuke_-]

@@jacoboneill2494 so what are quarks and gluons then?

[@jacoboneill2494]

@@-_Nuke_- quarks are thought to be a type of electromagnetic field oscillation. leptons (such as electrons) are too, but the opposite way, like crests and troughs of a wave. gluons are thought to be oscillations in another quantum field (strong nuclear). they provide the atomic "glue" that holds a nucleus together.

One more thing is that the picture counts with 4 orbits that my self thinks is what makes them think that there are for some reason more particles than protons and neutrons, my self think that every thing in all systems are made of the same thing, just in diferent temperature and maybe just some parts are waymore compacted than others, if you see meat, bones nerves etc, are made of same thing that by the end are atoms even Sabine say not, but who am i to say so maybe she will explain it later.
