hmmm - I don't mind the idea, but we could just as well say "is electromagnetism responsible for life on earth?", or is oxidisation responsible? Or, are large outter planets in a system responsible? There isn't anything uniquely or exclusively important about gravitational waves leading to life, it's just another natural phenomenon of many that combine to create the processes and circumstances for life's appearance.
So there's nothing really insightful or particularly revealing about the paper I believe.
That’s a very sound, and realistic, conclusion. Echos my sentiments as well.
@@Lars_808 oh, yes. Nice one Lars. :)
@@WillArtie 😂😂
glad other people share my view. you can condense this down to "life on earth is possible because of the way the universe was when it popped into existence" the real news wouldve been "if gravitational waves stop coming life will cease to exist". nothing wrong with wanting to know the ins and outs of how everything came together like it has on a particular area, but say it like it is.
solid. like mass...
Well, because these elements were available, they were incorporated into biology via the evolutionary process. What if they weren’t present? Would evolution have found another way to produce something like us?
We owe our existence *partially* to neutron star mergers which create gravitational waves, and are caused by gravitational waves, not the same really.
Evolution isn’t real . Just a phenomenon of observation .
Everything is designed and fixed n our universe , the randomness and coincidence also phenolic of math not of true reality .
The elements still would have existed, if evolution could have utilized more common lighter elements, it probably would have
For some of them maybe, but generally I feel it would be like "what if the fundamental constants were slightly different ?" We wouldn't be here
Well, how good of a time do you think you'd have without cobalt? The heart of vitamin B-12? Iron? Zinc? Hell, even copper?
Just those alone are critical catalysts in our cells.
Anton, thank you for revealing the gravity of the situation.
😄
Gravity is always getting me down.
Totally an unfair and oppressive law, repeal gravity!
Knowing our Congress, the idiots would try to...
Levity is the only way to escape gravity, thus the name for levitation.
The authors would have published earlier, but they didn’t want to make waves.
That was a weighty statement.
The paper has a misleading title. It's the collisions which are responsible for the heavy elements. And the gravitational waves play a role in the collisions and are caused by the collisions.
The title suggests that waves which are passing by now have an influence on our biology and our evolution.
yeah, I've been watching less and less of his vids lately, too much clickbait and filler
i agree
Agree. It's very less analysis on his part and just blind clickbait reporting.
Then don't watch and start your own channel... the title didn't suggest your surmise. I read it as the waves happened in the past to provide the building blocks for where we are currently, Easy to criticize harder to do.
@@billbynum2210Yeah but we like Anton and consider it a bummer when a respected RUclipsr is effected by the influence of the darkside.
Hmm. Anton is usually bang on in his Scientific Explanations and Popularization (explaining Scientific Concepts in a simplified way that makes them easier to understand and accessible), but here, I can't help but feel that he didn't exactly explain the exact role that Gravitational Waves play in the whole process.
He says some things, but in general, their role(s) stay murky by the end of the Video, which is surprising coming from such an excellent Science Communicator.
How can gravity wave if it doesn't have hands?
The only thing waving 👋 was Anton!
Why don't fish have armies?

So they don't go to war?
@@MR-intel Pirana and sharks kind of go to war, with their teeth and in armies or swarms of them
@@MR-intel The key words here are Arms (Arm ees) and Hand (Hand ees).
Like Leg (Leg-ees) or Fish (Fish-ees)
@@axle.student
You are lame. Not a student.
This is perhaps the closest to a click bait title I've seen Anton produce.
I think he go this backwards, as it is the merger which explodes the neutron stars and thus creates these elements. But, the side effect of the spiraling inward bodies is the gravitational waves. But the interaction with spacetime and the expulsion of these waves is what takes kinetic energy out of the orbiting neutron stars. So, what came first the chicken or the egg ? The waves, or the inward spiraling stars ?
Chat-GPT said this :
Cause of Gravitational Waves: The primary cause of gravitational waves is indeed the actual merging of the neutron stars. When the neutron stars merge, it's a highly energetic event that sends ripples through spacetime, creating gravitational waves.
Effect on Kinetic Energy: The emission of these gravitational waves is what leads to the loss of kinetic energy in the system of orbiting neutron stars. This loss of energy is a consequence of the merging process and the energy carried away by the waves.
The click bait title is basically the title of the paper. Yepp, we have click bait papers. Academia has fallen.
It seems we’re very hard to make, so I imagine the list of requirements for life must be very, very long.
Checking G-d's requirements.txt file. Hmmm ... seems to have a parody error. import gravity.waves import moly.
Possible, but we don't have any aliens to compare ourselves against yet, so it could be that life is just good at using whatever materials are available to function and reproduce
@@seanmadson8524 That's one reason to investigate other worlds in our solar system with very different environments from Earth. Granted there's lots more to learn, but so far the evidence is not great along that front.
Due to a concept called "Conservation of Complexity," one might argue that everything we know of led to the existence of life. 😂
I once heard a teacher mention a similar effect for human psychology forming based on everything that happened to us and our reactions and thoughts to them, and the teacher called it a sandwich theory. Like every event was another ingredient stacked on the sandwich. You just reminded me of this sandwhich theory.
Been seeing lots of derivations of the Rare Earth hypothesis lately. You could say anything is responsible for life, because it's present on Earth, or it has influenced it in some way. Correlation does not infer causation.
Grav waves have such an incredibly TINY effect, compared to everything else.
It's a bit like saying "You can hear loud music in a bar only because of the noise a butterfly makes by flapping its wings at the other side of your city."
They are a constant. The subtlety may mask their overall influence, but the consistency is relentless.
They don't do anything to directly influence life, at least not that anyone has seriously proposed yet.
The claim here is that the waves cause the neutron stars to spiral towards each other, and the resulting collision then produces the needed elements.
So the crucial direct step is the collisions, which would basically never happen without the waves.
Great video, but I believe the gravitational wave background is mostly caused by neutron star collisions, not the reverse. Blackholes are also at least partially responsible for this type of background, but I would be astonished if any of the elements you mentioned were produced during the merger of black holes or the merger of a black hole and a star of any type.
As a result, it is entirely fair to say that the conditions responsible for creating the gravitational background were also responsible for creating the conditions for life, suggesting as you that it was the gravitational waves that were responsible seems to be putting the cart before the horse.
Please correct me if I am not seeing this correctly. Your video was wonderful, and I am a huge fan of all your work. The world is a better place because you are in it.
actually your take is a lot more nuanced and interesting that the one proposed by this paper
Anton, although it was extremely unclear in his Video _(and I came out of it a bit frustrated as, contrary to his usual amazing work, the Gravitational Waves' Role(s) weren't explained much),_ seems to have been saying, or rather Implying seems to be more accurate, that Gravitational Waves play Roles as:
1- Aiding or enabling the process of Neutron Stars Mergers.
2- Also being a Result of those same extreme Density Objects' Collisions (Neutron Stars, Black Holes, etc.)
Your Post is orders of magnitude more in-depth and nuanced (as the other User pointed out) than Anton's explanation.
You mentioned how you doubt that Black Hole Mergers/Collisions and a Black Hole & a Neutron Star Collision could be responsible at all for the Elements discussed in the Video.
I hypothesize/speculate that in such cases, either the Production of New Elements or the Propagation of these is still very much possible because of the extreme Environment around these Objects and how those Collisions can rip apart Atoms and Launch, Propel the resulting Matter at incredible Speeds, which, to me, seems to Logically allow the R-Process to happen, either Locally or when the Streams of Matter Interact with Gas Clouds & other Matter (through a massive Infusion of Neutrons).
However, I don't know for sure if that's really a phenomenon that can happen in this way.
Also, I kept wondering about the Gravitational Waves & GW Background's potential Role in Propagating, Disseminating the Neutron Star Mergers' New Elements across the Universe...
Something that I don't believe has even been touched on in the Video and which seems a very important Factor in enriching Solar Systems, Planets, Gas Clouds, etc. with the new Elements, which would definitely be playing a huge role in the Origins of Life, the way it Evolved (IF it could have Evolved without), and more...
That's why I am left disappointed with this Video from Anton, because it's very unlike him to leave out so many glaring issues without even acknowledging them!
To my understanding-gravitational waves are created by inspiral.
Inspiral occurs over millions of years as pairs of dense compact objects (Three types. (a) two black holes, (b) two neutron stars, or (c) one black hole and one neutron star) revolve around each other. As they orbit, they radiate gravitational waves that carry away some of the system's orbital energy. Over millennia, this causes the objects to move closer and closer together. The closer they are, the faster they orbit each other, which causes them to radiate stronger gravitational waves, which causes them to lose more orbital energy, inch ever closer, orbit faster, lose more energy, move closer, orbit faster... etc. The objects are doomed, inescapably locked in a runaway accelerating spiraling embrace till colliding.
Most kilonova explosions are from two neutron stars mergering in a binary system but some smaller percentage of kilonova are created by the merger of a (1) neutron star and (2) a black hole. This type of kilonova is thought to be more powerful than a neutron star -neutron star kilonova- thus likely making more r-process elements than a regular kilonova.
It is also theorized that both neutron stars must first be created by an ultra-stripped supernova and a closely orbiting massive star that is in the process of becoming an ultra-stripped supernova itself.
An ultra-stripped supernova is the end-of-life explosion of a massive star that has had much of its outer atmosphere stripped away by a companion star. This class of supernova lacks the explosive force of a traditional supernova, which would otherwise “kick” a nearby companion star out of the system.
As The current neutron star would have to form without ejecting its companion from the system. An ultra-stripped supernova is the best explanation for why these companion stars are in such a tight orbit. To one day create a Kilonova, the other star would also need to explode as an ultra-stripped supernova so the two neutron stars could eventually collide and merge.
These systems are so phenomenally rare that only about 10 such progenitor systems are thought to exist in the entire Milky Way- and only one has ever been discovered.
On another note, a hypernova might have also produced all the heavy elements needed for life in the Milky Way. But they are thought produced by early universe massive stars that existed only in the first few billion years.
I dunno about most of what you've said, but I would imagine such collisions would have to produce heavy elements, yes? Anywhere matter hits massive densities, you'll see a lot of fusion.
I think it's because a pair of neutron stars which orbit each other will lose energy from the gravitational waves they produce. As they lose energy, they get closer together, and eventually collide. But without the gravitational waves, they would have remained in a stable orbit forever.
It's a beautiful coincidence we are even here, more people need to understand how lucky life is
ok but counterpoint, Taxes
I don't know if I am lucky to be here, mostly not.
Too crowded.
But looks that life is very rare on planets. Higher intelligence like us.
No coincidence, but a limitless complex system working perfectly, the process of creation.
Is a theist welcome to the table?
Well.
… so, thanks, gravitational waves and Anton’s mom, for giving us our wonderful Anton! ❤
I found a paper and you may have gone over it, but the hypothesis was that the more elements found on a planet the higher the likelihood it will be abke to create life. This is why I dont nevessarily think life would have been common for the vast majority of the universes history.
Not necessarily, elements alone wouldn’t make life. Planetary composition, size (thus gravity, spin rate, etc), parent star composition and output/distance/etc, orbiting bodies, sister planets and their characteristics. All these things affect the formation and especially the advancement of life. A room full of Lego’s does not a Lego house make.
@@inglebear84 Truth is, we know nothing about the formation of life. Nothing!
@@t16205 actually, we know a tremendous amount. That, or almost every scientist everywhere is wrong.
@@inglebear84 We dont even know how life started, or where it came from, we dont know if life has to be carbon based, we know nothing.
@@t16205 yeah, we know it can’t be carbon based. No, we don’t know how it started. Yeah, we know it’s next to impossible for life to exist anywhere but at a location identical to earth-with our unique moon, sun, planetary neighborhood, rate of spin, ocean/landmass ratio, local star cluster, position within the Milky Way, etc etc.
You’re doubting solutions to issues that most actual researchers have long moved past. There’s still the unending search for life, but the parameters for acceptable conditions continue to shrink, not expand.

I love Anton's smile at the end of each video! I'm a former portrait photographer from the time before everybody had their own HD camera in their phone. The young children around age 3-5 go through a phase in which they give their whole being to a smile. Every part of the face lights up like Anton's face when he smiles. It's such a wonderfully wholesome thing to behold! The children's smiles often evaporate in their teens and reappear again later once they realize they aren't too cool to smile.
Earth's gravity is specifically, precisely the exact gravity most Earth animals need to reproduce. Low gravity can even mess with a guy's ability to perform baby-making activities. Life as we know it can't exist without our own gravity, and more "exotic" space gravity (waves) too!
We are all made from the stuff of stars, right?
we are light frequencys radiating love
Fascinating! You have some of the most interesting videos on astronomy and origin theory. I enjoy that you share facts on what we(you) know and open to exploration in a practical way. You also keep your videos brief and translate the hard science in an easier way for the general public to understand. Well done! I am sure Sagan would be a sponsor for you!
great show Anton.
Oooh, I feel so glorious and rippley.
Without gravity, we'd all go flying off into space!
Without gravity, we'd be timeless. :)
Gravity is just electrostatics' another field modality of magnetism, electromagnetism etc. and is non point source, meaning that when we jump out of aircraft' we don't fall towards the poles. Just like a piece of metal (ferromagnetic) would also stick to the side of a magnet.
Wonderful as always Anton. Thank you. ✌️😉
Such an intriguing idea! I love that so many things in the universe from the infinity great to the infinitesimal played a role in our coming to be and our continuing existence.
Stardust..I've always appreciated Sagan's vision.
Thank you, Wonderful Anton.
In Yoga it is taught that material life is a consequence of a movement....Also we are a consequence of the movement of our black hole, the sun and everything we haven't discovered yet :)
Love the channel, thank you for being wonderful!
“Conservation of Complexity” is a scientific euphemism for “We have no effing idea.”
Love the videos Anton!
Fascinating stuff! Makes you wonder how special life on earth is...
Special and temporary. Good planets are hard to find and are ephemeral like flowers in the spring.
@@coweatsman Well said!
I favor the Rare Earth solution to the Fermi Paradox, but that's tied, at least in my mind, to the moon. The study here basically says that gravitational waves were involved in the creation of the elements necessary for life, which isn't quite the same thing. Still, I agree that it's very interesting stuff.
@@bookman7409 Yes, also because having just one moon is also thought to be rare, but who knows, maybe just our kind of life? The not knowing what's exactly out there in space is part of why it always stays interesting too!
@@observingsystem For my part, it isn't the number of moons so much as the proportions, and the tidal forces involved.
But you're right, we still have maybe scratched the surface enough that we can hang on with our fingernails. So many mysteries, so short a lifespan.
Gravitational waves aren't what created the elements, the collisions did or fusion reactions did. Which is something we already knew. I'm failing to see how gravitational waves have any relevance to life based on this video.
Same. I believe the propagation of light creates matter. And light is electromagnetic. As per every kind of element ' I'm stumped on that one!
He mentioned the waves are what allows orbiting neutron stars to eventually collide.
@@nathanweiler128 The title of the video is implying something else. "Gravitational Waves contributes to collisions between neutron stars" would be the more appropriate titled.
This report is amazing. For humans to be, an incomprehensibly large environment was required for producing the required materials.
Great video, love it, thanks👍🤗
just makes existence look even more like an intentional life generating sandbox.
I bet you could even get ai to do some computations to figure out which combinations of events, when and where, that were required to make man and then map the cosmos for locations that may have received similar combinations of events in similar proportions.
always thought it was an element of this, not in it's entirety but as a part of the mechanism.
"Life on earth exists becouse the elements of the periodic table do" isnt exactly a surprise...
Hello wonderful person! ❤
This one is VERY good. Thank you !
interesting articles from René Heller in Sterne und Weltraum 5/2024: the young Moon, which was much closer to Earth, helped keeping the oceans warm, not freezing, by tidal heating for 100E6yrs, while the sun's irradiation was less than 80% of today's! in arXiv2007.03423 also by Heller, R. et al; and arXiv2002.08806 of Shapira, A.
The sum of the tidal effect was initially +5°C on planet Earth.
I was blown away when we discovered gravitational waves, and now I'm blown away again 😮
gravity generally stops me blowing anywhere.
Brilliant!!!
Anton, I watch a lot of your videos and like a lot of them, but I rarely have anything to say. This time, I just want to say thank you for brightening my day just a little bit. You're awesome.
Hey-Anton IS awesome. Absolutely a wonderful person.
6:32 says Bromine is produced in neutron star collisions, but the table at 1:01 shows Bromine is 100% formed by "Exploding massive stars", and 0% by "Merging neutron stars". One of these must be an error.
Why does this not have more upvotes? Came here to say this. Does new study contradict received wisdom?
This video reminded me to buy Iodized Salt for my 96-year-old mother. I'm surfing gravitational waves out the door...!
It's hypothetical, but one thing for sure. We know less than we try to get.
DMT will teach you things science cannot.
I've seen the spectrographic analysis of the famous kilonova that was observed in EM radiation and gravitational waves. The analysis showed heavy metals including gold, etc.
So we are not "Star Dust", we are "Super Nova Dust". "I was forged in a super nova, come at me bro!"
Carl Sagan said we are made of "star stuff"❤
Joni Mitchell sang "we are star dust"❤
This smile 9:42 😂❤
Binary stars are really mating stars.
Its the dance of life.
Another great video.
and by this you can also tell the computers/creations processing speed and capability/limitations. 🤔
neutron stars are still star remnants, so therefore stars. Carl Sagan was NOT underestimating things in the LEAST!
I watched Cosmos on PBS in 1980.
Thanks Anton.

The butterfly effect, cosmic edition
I once read a science fiction story, possibly 40+ yrs ago, where a civilization developed in a star system that didn't have metals. I bet the premise was that their region of space hadn't seen enough novae to generate heavier elements. Their biology was different and their space technology involved a lot of ceramics. Anyone remember this?
Sounds very interesting. I never heard of it, but wish to know.
That sounds like the Conquerer Trilogy? I could be wrong, but I think it's by Timothy Zahn?
Anton did a piece just a week ago about nearby galaxy apparently having far less iron (iirc) than ours, probably because of fewer supernovae. Raises some interesting questions!
The title of the article Anton is commenting on is clickbaity but it is good science.
Moly is one of my most favourite Elements
Fascinating. As a layman I was just trying to keep up, but this fits into many of my theories. The way that everything seems to explode only to regenerate in another form is awe-inspiring, only to eventually blow up again. Entire galaxies do this.
But galaxies don't blow up. They are more like the entire corporation, with production facilities, storage compartements , etc. & etc. They do remind me of huge cells, even information-coupled with each other through electromagnetic fields. Large scale pictures of the universe look exactly like neuronal networks. Our host star and its surroundings just an enzym- or protein-factory within a cell from this giant organism?
" ... my theories." should be " ... my hypotheses."
Curiouser and curiouser.
Whoever evaluation is, he/she/it must be extremely intelligent and powerful. That’s for sure. Wow!
I still have gravitational ripples when I'm on a trampoline.
If we ever get a good 4K remake of Parasite Eve.
Not only should all these new science discoveries be baked into the story dialog.
But Mitochondria Eve should also have a Gtavitional Kilo-Nova Wave attack to spam player one with from across the map.
Best Action RPG ever made.
Just as our individual existence is a result of pure accident, so is everything else in the universe and indeed the universe as a whole.
I take comfort in knowing that every event in my life ( good, bad or indifferent) that occurred before my beloved children were conceived was necessary for their existence.
Random is not possible according to to science many scientists actually no longer believe in this bs . Our galaxy has the most unique planets even out own black hole different from all universe black holes there even a barrier protects out galaxy. Our sun 1 in 99999999999999999999999 all this and peoole think its random lmaooo
So gravitational waves cause the neutron star collisions, and those then produce the needed elements.
According to a study from several years ago we can also thank gravitational waves a couple steps back for about four fifths of the world's gold.
excellent. thanks.
Gravitational Waves are truly good Vibrations
This gets my attention. How the elements are made. Must mean something. Isn't it all grand?
We are just surfing along on gravitational waves ! At the speed of light ! Like everything else ! 😝
These gravitational waves would rip you and your surfboard apart if you were close enough to the kilonova.
Quick note: there’s a semantics error within this vid and possibly the paper (or simply within the viewer) which is suggesting that these waves were “solely” or even “primarily” responsible for life. The word ‘responsible’ does not automatically denote sole or primary cause, but one of an important or even critical role. One of countless factors that, had one not been present, life would not have formed.
Now, it is entirely possible that if these waves were the “initial” critical factor, that would then make them “solely” or “primary” responsible, as the word is presumed to reference in these forums. I haven’t read the paper, so I don’t know the authors intent.
Hey Anton!
Deep wave videos brought this up in results. Super happy😂
Now this could be a real Fermi Paradox kicker, oooooooooo.
Our wave particle duality 😂
I think you can perhaps predict the abundance of life in the universe based upon the relative abundance of the elements essential to life in the universe. We are the universe, observing itself.
This takes the Butterfly effect to a whole new realm.
I agree with others here that gravitational waves don't cause neutron star collisions but are caused by neutron star collisions.
Hello, wonderful person!
EYY NICE CUT MAN
Interesting topic but it is confusing. Similarly to others in the comments, I did not understand why say that gravitational waves are the cause of merging of neutron stars and production of life-relevant heavy elements, when should be another consequence. Later I read the paper and they mention that release of gravitational waves is a process happening before the merging by relativistic reasons. Importantly enough, is this release what it seems to be causing loss of momentum and finally leading to the merging of these stars and consequently the heavy element production. In this sense gravitational waves are the cause, but looks to me as a hype: These are part of the process, not merely signs or proxies of the process, but you also need a pair of binary neutron stars!
Gravitational waves are a result of the merger between neutron stars, separate from the r-process that produces heavy elements…but I get the “poetry”
Amazing... Our very existence dictated by cosmic events...
I've heard it said that we're the result of over 40 supernova. Wish I could find the reference.
Another example of the anthropic cosmological principle in action - or in this case, over-action. We have to remember when we talk about “necessary” that we have as yet no other examples of life from another corner of the galaxy that maybe had other local building blocks to work with. When generalizing from a data set of one there is no difference between a “requirement” and an “accident”. In this case we are talking about trace element that got worked into the geometry of the folding of certain randomly useful proteins somewhere in the evolutionary process, so very probable “accidents”. But I do think that the fact that my trace elements were likely formed by colliding neutron stars is interesting - and possibly the basis for a good pick up line. Just not actually profound.
My initial reaction to the headine was similar to my reaction the first time someone told me that general relativity was necessary for the GPS system. “What the…? Oh yeah, it’s obvious it would have to be!”
There we go again
Psalm 86:12-17 ESV - I give thanks to you, O Lord my God, with my whole heart,
and I will glorify your name forever. For great is your steadfast love toward me;
you have delivered my soul from the depths of Sheol. O God, insolent men have risen up against me;
a band of ruthless men seeks my life,
and they do not set you before them. But you, O Lord, are a God merciful and gracious,
slow to anger and abounding in steadfast love and faithfulness. Turn to me and be gracious to me;
give your strength to your servant,
and save the son of your maidservant. Show me a sign of your favor,
that those who hate me may see and be put to shame
because you, LORD, have helped me and comforted me.
Not sure how Uranium and Thorium are somehow responsible for plate tectonics and such...Or did I misinterpret what was stated?

Thank you, it makes existence on Earth all that more amazing. Just imagine: Earth without Molybdenum or Iodine would be uninhabitable. Creationists will have a field day.
The first 36 primordial periodic elements match the sequence and function of the 36 decans of the solar year. The ancient time keeping systems, are based on recognition of subtle energies or resonances, that change with precise periodicity and they are described in detail as it relates to morphology, and function.
This one basic thing,...is what science should be looking at. Something totally pervasive is going on.
Hmmm. Interesting 🤔
So in a way it seems we are kind of, the stars' ghosts or spirits billions of years after their death 🤯!

Perhaps we will see the postulates: “Light is an ordered vibration of gravitational quanta, and Dominant gravitational fields control the speed of light in a vacuum.” There is a proposal for the joint invention of a HYBRID gyroscope made of non-circular coils with optical fiber, where the light in each arm travels 18,000 meters, without exceeding the parameters of 0.4/0.4/0.4 meters and mass - 4 kg.
