These orbits can be very eccentric without immediate instability, although more eccentricity also means the effects of gravitational wave decay is stronger. Although now that I put it that way, you can argue it that way too. If orbits were all 'nice and neat,' then gravitational wave decay would require much longer times to take effect, possibly often beyond the lifetimes available so far. I think there's a good chance if you run the probabilities, most if not almost all cases where gravitational wave decay have resulted in a merger involved some sort of perturbation to the orbits that significantly sped up the process.

@@Krokodil986 Well, no, there'd be almost no (relatively speaking) stellar reminant mergers without grav waves. Remember, these are earth-sized objects, with Roche limits (how close they can get before merger) of similar degrees. That is, we could have two white dwarfs/neutron stars/stellar black holes pass a fair bit closer than the Moon is to the Earth, and without the effects of gravitational waves, they would happily continue on like that forever. I suggest you play around with some orbit simulators - getting that close to a massive, dense object is incredibly difficult, probably much more so than you realize! It gets exponentially (quite possibly literally, although not sure off the top of my head) more difficult as the target increases in mass and density.

And yet, the more impressive things are seen as mundane... that the universe has forces that interact and equilibrate at all.

Over time, the quantum state will exchange information with its environment, meaning it interacts with it or couples to it. These couplings will change both the environment and the quantum state, resulting in a transition from quantum-typical indeterminism to deterministic behaviour. Therefore, the universe is its own observer all the time. If a tree falls, it falls. This also invalidates the argument for Schrödinger's Cat. The atom, if it decays, will emit particles and radiation which interact with other particles, thereby confirming the decay to the universe. So either the atom decayed and the cat is dead, or it did not decay, and the cat is alive. The cat as a macroscopic system will anyway always be either alive or dead, never anything in between. It experiences decoherence between its quantum states all the time.

I mean, different laws in a universe would garner different results, but by the very nature of our universe existing it is most reasonable to assume that other universes with other less stable configurations also have tried to exist. We live in this one because, in the course of infinity, this one was habitable. Another consideration is the nature of efficiency. Much like an electrical circuit will choose the most efficient path, it may be that the formation of the universe settled on the most efficient, stable configuration. Much like a bubble will always be a sphere, the universe may have had some strange happenings at first, as it flopped around in different configurations, but ultimately settled into the life supporting form it is in now.

In our real life experience at the mall with a coin drop in a funnel we have, given that angular momentum must be conserved, the coin's speed increases as it goes further down the funnel. Eventually, the coin gets to the narrowest point of the funnel, where it orbits fastest, and then falls into a collection box beneath the bottom of the funnel. The final fall through must be caused by friction between; the coin, the air and the funnel. Looking at neutron stars, if we didn't have a loss of energy somewhere in the system how much longer would it take for them to hit each other? Or would they destroy each other by tidal forces? I hope there is a difference and that we can look for the difference through theory and measurements. Loss of energy seems the most likely to me and gravity waves could be it.

You have a very good sense of humor for a German person ;).

The content of this paper was a surprise, given the title. I was expecting a discussion of how human life evolved under particular conditions of gravitation unique to planet Earth which conditions are now necessary to sustain these life forms. No doubt my predisposition to doubt the possibility of "sailing away" from this planet is showing. A question I frequently ask myself is whether the collective frequencies of all Matter, Energy, Space and Time etc. on planet Mars will be so profoundly different than those on Earth that humans will be unable to survive within the context of a Martian orientation to the rest of the universe. This gets down to the difference between what conditions are necessary and what conditions would be sufficient for the sustenance of Earth-Human life on planet Mars. Without splitting hairs, we can say that human life evolved on this planet within the exact set of conditions that prevailed during that period of evolution. The fact that conditions changed during that period or remained the same does not invalidate the proposition that the extant conditions WERE the conditions extant over that stretch of time. And this set of conditions, static or dynamic as the case may be, can be listed, measured and evaluated by science. Or can it? There is a difference between the list of conditions that science can evaluate and the list of ALL conditions that may influence the sustenance of human life, because the latter would have to INCLUDE conditions that science is not yet able to evaluate. One might assert that science already knows every condition necessary for the sustenance of human life. But that is not likely. To the brave pioneers who will be the first to contribute data points to this controversy (and their mortal particles to the planet Mars), I salute you (even if what's his name is one of them).

I have this suspicion that life of some form or other is possible under an unimaginable variety of conditions, including conditions that would be present in universes different than ours. Until we know just how easy or difficult it is for life of one form or another to evolve from nonlife, we can't really estimate whether or not our particular universe is especially conducive to the formation of life. And by the way, you and Anton Petrov ought to consider joining up, I think you might make a good team for creating science KZread videos.

I find it difficult to imagine in all the billions of cubic light-years of space that any matter could clump together with other matter to make anything by chance.

I'd only run across this theory recently. What I read didn't state that gravitational waves were actually necessary to life, but that without it creating the heavier elements, it would certainly be different. Now I have to go back and read it all over again!

You have great sense of humor 😂

For me it's a symptom, Sabine. A symptom of the fear some scientists seem to have of life. I don't know what it is... But every time we discover something that suggests life should be out there, something like that pops up. And I'm not talking about little green men - neither gray. I'm talking about freaking microorganisms! Anyway, stay safe there with your family! 🖖😊

I'm now considering writing a paper for review: The Necessity of Both Water and Oxygen for Anthropic Existence and That Humans' Were Originally FISH

This reminds me of the new study that proves that sunlight is necessary for the production of hot peppers. I was very surprised to learn that, too

Most of the most common elements in the periodic table are essential for life.

You don't need gravitational waves to have most of the elements heavier than iron, since these are very well created during supernova explosions. Hence the famous sentence "we are all stardust".

Thoughts on Dr. Becky's video about the new JWST results potentially "solving" the hubble tension?

I'd like to add a bit more detail about the eclipse argument. I think this is expounded in the book "The Privileged Planet", but I haven't read it. 1) The sun has to be ~.5° in the sky, for "habitability". It could be farther away, but then it would have to be bigger in order to be sending just the right amount of energy to have liquid water/etc. (It can't be brighter and smaller, because then it would be the wrong kind of star, or ... something; I asked Gonzalez face-to-face (on 4/8, appropriately) and he said something along those lines; I worry about misquoting him, though.) 2) The moon has to be freakishly large, like our moon, in order to get tides and all the other good things the moon does for us to make Earth "habitable". Therefore, on a "habitable" planet, the moon and sun are likely to be .5° in the sky, thus causing nice eclipses like we have. No idea how sound or not that argument is. The observation is paired with other observations: 1/1 ratio of moon/sun angular size is quite rare, no other surface in our solar system has nice eclipses except for Earth. Also, this facilitates interesting scientific measurements, such as how during total eclipses we've used spectral lines to discover helium in 1868, or observed lensing in 1919 to confirm relativity. The book makes a big deal about habitability characteristics like this facilitating scientific discovery; I suspect a Texas Sharpshooter here, but, again, I haven't read the book. Also it seems like Saturnians could use Titan's shadows to do spectography, but what do I know. I think the idea that a planet where carbon-based chemistry is going to work etc is probably kinda rare is not controversial, but I don't know if I know enough to be convinced that it couldn't happen without a big moon, or with an even-bigger moon.

Well processes that use sulphur were present in early life and thats created by neutron collisions. But i always considered waves a byproducts of the collision then again without gravitational wave collisions would be less in occurrence.

These convoluted, Angels and Demons novels - we need to work on getting solid answers to the smaller questions first. Maybe laying off the bong a bit would help.

Please explain why heavy elements were not made during the big bang. A lot of things collided and were put under great pressure then as well.

But don't Stars make heavy elements beyond Iron? I've read they do, it's just that before Iron fusion produces energy, but for >Iron fusion cosumes it. So in small qunatities heavier elements are produced too. Am I wrong?

Nice move with the Iodine and Carbon. IC = Iesos Christos, right? Add Yttrium for Yahve, and of course there's Thorium and a bunch of others, enough for a sizable pantheon.

This Video is almost the same as if I would say: Human life only possible because of Water. I guess the mixture is important. All together makes life just possible

Sabine: "...laws of nature are what they are and that would allow life." Exactly. This doesn't exclude a creator, it just takes the human narcissistic navel gazing of anthropic means out of it.

I think one of the most fascinating things about black hole/neutron star mergers is that a neutron star is gone in a fraction of a second!

Don't forget that radioactive decay of elements heavier than Iron is thought to provide much of the heating (50% ?) in the Earth's core that results in plate tectonics and our protective magnetic field.

I knew I could depend on you to make the argument from fundamental Misanthropic Principals, one of which ruled my high school with an iron fist (his other fist was flesh and blood).

This paper does seem like a stretch of inference. I wonder what will be discovered however when the space based more widely separated interferometers are platformed.

Thanks to the editors for chilling out on the meme-injections today 👍👍

Anthropic comes from the Greek word meaning “man” not human 3:29. We use anthropic as in “pertaining to humankind” or “mankind”. Accuracy lends itself to credibility, even if we know the context of “man” in this way is interpreted as “humankind.”

Permutations across the cosmos will explain so much. They do need something like this to excuse why some nebula sat idly by 12 billion years to collapse without heavy elements while mature neighbors did . You can't fix this by adding 25 billion years. Seeing this mixed in as far as we see and as close by young and fully mature neighbors is a real delimia But it also mirrors the Cambrian explosion and multiple genetic codes of life we've found. Obviously it's different events but both are trying to accommodate the same grand unified evolutionary singularity model both are witnessing the same horizon paradoxes problems. To scale these show up a lot as above so below .lol

ahhh... I finally figured out why there is so much more matter than antimatter. Its because if there were close to equal amounts they'd annihilate eachother, leaving too little matter to clump together to make stars and planets, on which eventually life would evolve to ask the question: "Why more matter?

Hi Sabine, is the Universe some kind of sorting algorithm that "runs on it self" and sorts for complexity, whatever that is? Liebe Grüße aus Tübingen 😄

Even without gravitational waves neutron stars would lose energy if they orbit each other. Both stars have magnetic fields which interact and create heat and therefore radiation. It would only take longer till the neutron stars would merge together. The question might be if enough neutron stars would merge and create enough heavy elements before the universe would have been expanded to much. Then the next cloud of hydrogen, which could collapse into a new star but needs a push from the merging neutron stars would be to far away...

To paraphrase Arthur C. Clarke, any physical explanation of the universe sufficiently counter intuitively improbable can be shrugged off and cited as evidence of the super natural. IIRC Newton's theories of mechanics and gravitation explained heavenly orbits wonderfully but how the mechanism giving "spooky attraction at a distance" worked was left as an exercise for the reader.

I have a somewhat long comment on this, so I've sorted it for reading pleasure. TOPIC DISCUSSION: If you put 1m grains of sand in a churner, then check the churner after maybe 3 hours of churning, you will likely see complex clumps/clusters that work under a shape-governed ruleset aside the noise of the sand. The complex structures build even more complex structures if the clusters clump in a certain way. THE YAP: This kind of thing happens everywhere all the time, but instead of sand; it's the superfluid of space. The churning of the superfluid of space consistently creates particles that last for a blip, or sometimes create a structure complex enough for the particle to stay. Look at virtual and real particles as bubbles in water as an example. TOPIC POINT: No matter what weight you give to this fluid, the laws of physics will always conform to it, since that's what emerges the laws of physics; life exists because emergent complex structures in an existence of noise can have even more complex structures made of complex sub-structures(the structures within the main structure). EXTRA YAP: Temporary structures exist because once a structure looses stability(a.k.a meaning) it dissipates. At all words, it doesn't matter much if you subscribe to a weird model. /:

To keep it short, life is an emergent sensory apparatus. Life and the universe is like you and your taste buds. The buds for the most part are sectionalized and have their own minds(sensories) but are part of you. For your comfort just imagine yourself as an emergent inner compart of the universe. 👍

Sabine, no, we actually had to build TWO apparati several kilometers in size before we figured out gravitational waves = origin of life.

How about this? The Universe has always been this way. And the fact that we formed based on the conditions, we can talk about it made us (unintentionally)

Dear Sabine In Cixin Liu’s book the three body problem, (currently adapted for and playing on Netflix) the antagonist boasts about having created a sentient computer from a single proton - by “unfolding” it’s presumably 11 hidden higher dimensions I know this is an probably unfair question but just entertain the thought. Please …. 1. Is it possible to unfurl/ collapse higher dimensions into our 3 dimensional reality ? (eg. Something akin to origami ? The reverse of when you fold a sheet of paper into a box) 2. If so what would be you approach ? 3. Lastly, would a process of unfurling/ collapsing higher dimensions into lower ones exist inside the singularity of a black hole ?

There is almost certainly some parameters of the universe that are "anthropic" in the sense that if they were anything else, we wouldn't be here. That said, there are two problems with anthropic arguments: 1) That doesn't mean _nobody_ would be there. String theory posits something like 10^500 mathematically consistent sets of universal constants, and its entirely possible that estimate is low given that we've kind of given up on string theory being the true "theory of everything" (of course that estimate could also be high, but its the only one I know of that gives us any sort of useful attempt at quantification). Hell we don't even know (outside of string theory this time) whether many of those constants were "chosen" from a continuous spectrum or a discrete one. If its the former, then there's in principle an infinite amount of possible universes (though most of them would be so similar to their neighbors as to be indistinguishable). 2) Worse, its a dead-end argument. Too often the anthropic principle is invoked "because we don't know how it could be anything else", but that's not the same as stating it can't be anything else. The limits of human knowledge has no bearing on the universe. You would think that should be obvious given how much more knowledge we have now than we did even a few decades ago (the Hubble Deep Field image was only taken in 1995! And JWST is giving us new knowledge almost daily. Those ancient stars didn't just miraculously pop into existence the moment we decided to build a bigger telescope - they were already there* regardless of whether we knew about them. *From our perspective, for any pedants who want to argue about what time means across large distances.)

When people ask me to explain how life got started I pour oil in water shake it and let it settle and go on talking about energy gradients and the biospheres. But all life is dependent on the sun the proper solar dynamics an its interactions with the available cemical structure on any planet. I thought it was a silly paper.

it's strange to who grew up with the classical model to imagine two bodies orbiting each other to just decay and crash but then if we can detect gravity waves when it's losing some tiny amount of emergy..so it makes sense. but how is that energy received? if space slightly changes by stretching and compression what does it "feel" like? we don't actually move if we're sitting still in space and space is changing size, right? if a photon hits me from far away it increases the energy level of one of my electrons and i guess enough of that would feel..warm. but what do gravitational waves feel like? if there was energy loss there shouldn't there be energy gain somewhere along the path it travels?

In another universe, the Zorts will be wondering whether their universe had its ratio of strange quark to up/down quark masses adjusted to allow the stabilization of the strangelet nuclei required for the non-radioactivity of the Feynmannium needed for their frammistan gland . . . .

I read some rather involved posts that we're critical of constants as mundane ... and fine tuning ... and underlying structure predating God ... I'll give you more clues about our univers: and a question. If you tie a constants to have a geometric meaning, does a constant have more consequence? Yes If you have a string of any length and bend it at any point you like. You can compute an area. Make the side lengths equal you have a sqr. You make unequal sides you make rectangles of decreasing area: quantum deformation trees String length =10 10= 5+5 sqrt area =25 10= 4+6 rect area =24 10= 3+7 rect area =21 10= 2+8 rect area =16 10= 1+9 rect area =09 An what you may not recognize: the deformations are quantum 25 max area 24 = 25-1 rect 21 = 25-1-2 rect 16 = 25-1-2-2 rect 09 = 25-1-2-2-2 rect
