Kinda crazy to think that we are living in a time where we still don't know where stuff around us comes from. Also, reading that abstract... it's just incredible that we not only detected the gravitational wave from a collision, but then were able to actually find it based on that data, and analyse the light coming from it to detect the presence of elements.... amazing!

Quran 36.36 All-Glorified is He Who has created the pairs all together out of what the earth produces, as well as out of themselves, and out of what they do not know. Everything animate or inanimate has a pair; we can see opposition and complementarity in all created things and beings, whether in physical, chemical, moral, or psychological qualities. Recent discoveries of complementarity and opposition among sub-atomic particles may be an instance of the kind of pairs that we do not see directly; there will be many other instances of "pairing" of which we remain ignorant. Intelligent people who are ready to think open minded , will find the truth

Carl Sagan’s Cosmos taught me we are star stuff from supernova, but new data shows that it’s from collisions of neutron stars that created the majority of heavy elements that are needed for life. If Carl was still with us I’d like to think that he would think that was way cooler than a mere supernova:-)

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...

Plenty of articles seem happy to provide only a basic scenario for star nuclear fusion: squash two hydrogen atoms together, get helium, rinse and repeat, run out of hydrogen, DIE. Now more do include the hydrogen-to-iron chain scenario, but a couple of things still seem off to me. 1. Would it stop at iron just because it absorbs energy? Surely the iron that's already there (they can't simply "step aside" to give way to other elements, can they?) would still be under immense gravitational pressure to fuse to heavier elements, even if they don't have explosive energy to give out. 2. Thereafter, do fusing heavier elements (i.e. cobalt and beyond) have similar energy-sucking effects? Everybody seems happy to say "iron takes away energy, end of story." 3. How do simple chemical molecules get joined together (in LARGE quantities)? Stellar explanations only talk about squashing elemental atoms alone, and then scientists excitedly tell us our bodies are made from stellar dust (because of the heavier elemental construction). But our biology is ultra-complex chemical compositions and reactions, and before that can happen, more foundational substance molecules must exist in abundance (e.g. H2O, NaCl, etc). I've never found an end-to-end explanation for this. 4. And following #3, how the more complicated chemical compounds are joined to form rocks and sand and the regular planetary matter.

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 😅

Heavy elements are created by: 1. R-process: Ultra-rapid neutron absorption without sufficient time for decay between neutron impacts. 2. S-process: Repeated absorption of neutrons with time between impacts for some decays to occur. 3. F-process: While energy cannot be liberated from fusion of iron and more massive elements, such fusions can and do occur. Thermodynamics favors such endothermic fusions at sufficiently high temperatures. Such fusions can cool the core of a star, accelerating collapse. Such fusions produce high mass nuclei which quickly decay into more stable elements. 4. I-process: Inverse fission caused when heavy nuclei collide (as in F-process) in the presence of very high neutron fluxes during supernova explosions. This process is approximately the reverse of ordinary nuclear fission. 5. N-process: when outer layers of tentative neutronium is bounced off of cores in supernovae, and are ejected from the stars, then spall into ultra-massive nuclei that quickly decay into more stable ordinary nuclei. Not all of the above processes are distinct, but rather grade into one another.

I wish you had pointed out around 2:20 that because universe was so hot and dense, the early stars were monstrous short lived firecrackers, that spread the new heavier elements quickly. This is often neglected (as you did) when explaining early star formation and drove me nuts until I took a college course. The stars right after the big bang were very different than what we see today, and the heat of the universe meant that they couldn't just dump the heat of their fusion outside of themselves, so it intensified the whole process.. The early universe was a sea of continuous exploding stars for millions of years, each explosion a minute portion of hydrogen and helium being converted to heavier elements and seeded around.
