"I speak from pure logic. If I let go of a hammer on a planet that has a positive gravity, I need not see it fall to know that it has in fact fallen." - Spock.
Except in star trek the hammer could be ancient Clark tech with anti gravity or teleport through a wormhole or create time dilation or send you in a simulated brain fugue where you perceived the hammer floating upwards
1. Intelligent life that develops high technology is so rare only 1 species at most masters space travel in any given galaxy at any given time period if at all. Earth like systems and planets have turned out to be very rare. 2. Distances between galaxies are simply too large to cross in a reasonable time period at sub light or even light speed and physics prevents any sort of wormholes or hyperspace. That would explain it.
Without superluminal travel, a civilization wouldn't have to be very far away for us to not notice it; by the time the bubble reaches a thousand light years, we can pretty much kiss any hope of seeing them goodbye. So life doesn't even need to be anywhere near a once-in-a-galaxy event for us to seem alone in this universe(though a thousand light years apart is still incredibly rare compared to what Fermi's colleagues were expecting).
Listened to this yesterday on Nebula. A deep and informative look at a topic that seems relatively straightforward upon first inspection. The number of things affected by gravity and how they scale with slight increases or decreases is astounding. Certainly a very complex thing to measure when it comes to life emerging and spreading. Fantastic work, Isaac.
Gonna be honest. I've been watching your videos for years. You are definitely the type of person that I would welcome to a fireside beer with friends in the backyard. All of our conversations end up with looking up at stars and wondering.
You've made an increasingly strong case that there are no complex aliens--with caveats. But if there are any others at all, it is interesting to think that we will only meet them after we've both expanded into cluster spanning sentient ecoystems. How wise or unwise might we both be by that time?
That's hard to measure. My own personal beliefs are that there are certain behavioral patterns that are endemic to humanity. No matter how transhuman or posthuman we become, there would still be traces of our imperfect humanity. Its kinda like when people say, "History doesn't exactly repeat itself, but it sure does rhymes." I think if humanity does colonize space, they would have mostly wisened up, but they would still fear the unknown of aliens.
At first the idea of using lasers to put a rogue planet in a close call or even collision course to a dense object to allow aliens in it to beat gravity out of it sounded too brute. But then I recalled that if brute force isn't working, you're not using enough of it.
Since you mentioned dragons egg can you help me with a issue I had with it? Since the organisms on the neutron star are subject to many days per second they seem to live and go about their business much more quickly than we do. However being that close to massive gravity wouldn't there time go more slowly than ours? Is it just not as pronounced? So the fact they consider many days as a second for us it is more significant and outweighs the slowing from gravity? Or an oversight by the author?
If their relative time was a tenth of our time speed, but they operate metabolically as fast as the walking proteins in our cells, then they would still be so far ahead of us like depicted in the story.
It does need to be pointed out that as energy rises with the square of velocity, doubling the orbital velocity increases the energy needed to reach that speed four-fold
How well could one launch a rocket from a balloon, or pair of balloons, or "air raft"? The former assumes a suspended rocket with the strap point being near the balance point, but not on that point. (gas bag/blimp with rocket at angle) A pair would probably need something pulling the balloons apart or a brace. That last assumes a platform lifted by balloon or blimp. Any of these would ease rocketry concerns in a deep gravity well. -=-=- So, the initial idea of floating semi-aquatic brontos would be less likely to translate to space-going via rocket.
I don't see how this could be a filter. A rocky planet in the habitable zone is just as likely to have lower gravity as high. And with lower gravity - even if just a few percent less - space flight would be much easier. And the argument involving super earths isn't a well informed one. The fact we've seen so many super earths has far more to do with the limitations of detecting smaller ones, than that they are actually less common.
1:00 - or what if what we really mean is "Where are the other life forms that behave exactly like our imagination of who we are and think we'll become in the future?" What if most of the premise of the Fermi paradox is just our imposition of the concept of humanity onto a galaxy that might be composed of alien intelligences that are all completely different from us, and from each other? What if there are millions of such races just in this galactic arm, but we're the only ones that see technology as a means of communication between races, if we're the only ones with the concept of civilisation in the first place?
Would a difference in Gravity change the fundamental way atoms and alike interact with each other? An unimaginable reality where different physical phenomena play out and the structure of matter is different. Thank you for the calming mood and the vast knowledge you share
almost make ya wonder if it's possible to train in High Gravity worlds at birth without the worries of Skeletal Structure breaking apart from the High G's alone. this could be the awesome front for a sci-fi style of superhumans.
6:00 in "Dragon's Egg" and its sequel, the space elevator was not made of solid material. It was a fountain of rings, launched using gravito-magnetic effects which they have access to because matter is hyper dense. Stuff that is dense even to them is fictional "monopole stabilized black hole dust". You've discussed similar elevators yourself, where launched rings can then lift things magnetically.
Isaac. Whats your thoughts on math being inherent or man made? The answer seems simple because things were there to count before we were, but there appears to be no clear consensus within the scientific community.
When discussing relativistic speeds, could you please touch on the effects of increasing mass and how that might affect the function of the ship and even the chemistry of lifeforms on the ship. Thank you.
Has there been a fermi paradox video regarding intelligence appearing too early prior to having oil or sufficient natural resources. Or maybe the natural resources are used up prior to space exploration?
I think it would make for a cool story to have an aquatic race reaching out of the oceans, seeing haze above... the atmosphere would be their first obstacle to space.
30:35 You skimmed a really good point but I am not even sure you realized it. Increased gravity would create the heat necessary for tectonics on smaller worlds, but will not make that world loose the heat any slower. It may also make the rock enough more dense as to meaningfully increase the thermal conductivity on earth sized worlds. So, the time overlap between having a magnetic field and surface temperatures conducive to life would be much reduced.
Perhaps there are more than just the four forces of the universe? Forces we don't interact with. There is matter that we don't interact with. Maybe we can use these forces indirectly to counter the four forces thus anti gravity & anti inertia. Blend it with quantum portation and trans form our atoms into the other force states and the generally theory of relativity isn't a thing.
Its a cool idea and forces we and other things were aware of dont interact with is absolutely possible and would be somewhat equivalent to parralell universes basically since they could overlap in space and have no indication even if their properties were identical to all our forces with the caveat that they only interact with each other and not any of our 4 fundamental forces. That said, the thing that is a bit more dubious is whether the eexistence of such forces could counter gravity. Not wholly dubious mind you. In a sense the utilization of the existing forces counters gravity via the release of energy from creating or breaking strong nuclear force bonds so it's not inconceivable that some small negligible normal fundamental force in its baseline state would in a different minimum beside its local minimum exhibit much stronger properties thay over rode gravity or generated effects akin to unlimited energy though probably actually not... I believe while it's not actually a force, though I could be wrong, that there's a couple theoretical partial and space time reactions that posit something to this effect, though, they exist within forces that do effect us, and past I heard such processes result in the universe cascading into the new minimum from the point of first minimum reduction at the speed of light destroying literally everything, so not entirely sure that example is what we want to use. Cant remember if thats the big rip or if I'm conflating another process? Anyway fun stuff.
A heavy planet having excessive volcanos could be a good thing for life if its covered in oceans. Providing tremendous amounts of materials and metal to disove into the ocean. Giving life a better shot.
Or, how about being covered in oceans (earth) and having a volcanic neighbor with a lower escape velocity (mars) to send that material? I think that may increase the chances even more, and given the anthropic principle I’m of the mind that we’d first have to find a reason to rule out mars playing a (weak) role in abiogenesis and our default thinking should be that mars was essential.
6:25 it would be possible to catch a ride on Star quake emissions or perhaps if you magnetized yourself enough you could traverse magnetic field lines since particles routinely escape a neutron star on those crazy potent magnetic fields
I was never able to recall the story I read about life on a neutron star I wouldn't say I thought of it often even on any kind of a regular basis but from time to time
Hey Isaac I’m wondering if elements of a heavier mass like supernova explosions making elements 114 and 115 and it’s bending spacetime and causing more gravity. Is anything like that possible? I think we just need to get the math right and change the constant because they are not finding anything else.
You mention "grabbing a drink and a snack" before watching your videos. That is misleading. My experience is, I need to grab a calculator and science reference books before watching your videos. That is so I can keep up with you. I still have to pause the video many times to absorb your content. I see why you pitch Brilliant. A person would need something like that appreciate your presented material.
IF 2 universes 'collided/intersected' what would be the forces that mediated which 'leaked' into the other? Is it number of forces (think universe with our 4-5, vs one with 50)? Or is it simpler: is gravity or cosmological constant (equivs) multi-universal? Would the universe that prefers enthalpy leak into the universe (like ours) that is entropic? Or vice-versa?
The problem with this is that you would need not only a theory for a metaverse that would allow for differing laws of physics, but also a mechanism explaining why the metaphysics translate differently in different universes. Since we currently have neither, the entire idea is an exercise in "mathturbation"(as critics of string theory have so bluntly put it) and so the results can be pretty much whatever you want.
An universe with 10x gravity will have life on bodies that have 1/10th of the useful gravity in our universe i.e. moons, dwarf planets. With even higher gravity asteroids might become candidates.
Baryonic Matter may be moving in time, one way, and Dark Matter traveling it the other way, in time. I suspect the matter we see is moving into the future, and dark matter is moving into the past. There may be more Baryonic Matter in the future, while there will be less Dark Matter in the future. Contrariwise, in the past, the opposite may happen. We know nothing about time or space or gravity, apart from our own Anthropic Measurement. Those three thing need more though. Richard Feynman may have been right
Stellar remnants - Couldn't you slowly stellar life the neutron star by beaming matter into orbit, assuming you find some source of effective infinite energy, reducing the star down to the point you could leave?
You know, I never considered this type of life before, some sort of quantum life. It would be an interesting fermi paradox solution if you could actually create quantum life that could even survive on a neutron star. Why expand out if you could create a civilization so small that the entire Earth could fit on a piece of human hair?
would gelatinous-style blobs be better suited to live on a high gravity world? just crawling and creeping across the surface and into the cracks and crevices of their homeworld - with or without intelligence? they would still need a (hydraulic) mechanism in their cells and bodies to counter the gravitational pull but wouldn´t have trouble with bone becoming too thick and too heavy and still breaking from the slightest pressure.
The weight of it all.

After an opening joke like that, exactly like the animation showed I too would throw myself out the airlock.
If you started in orbit, you are probably still in orbit.
2:56 "Earth is already the densest planet in our solar system" Given some of the people I've encountered, I believe it. Talk about dense! 😝
You've made an increasingly strong case that there are no complex aliens--with caveats. But if there are any others at all, it is interesting to think that we will only meet them after we've both expanded into cluster spanning sentient ecoystems.

Leave it to Arthur to drop a video on such a weighty subject as gravity.
now i understand the gravity of the situation...
To quote The Tick, "Gravity is a harsh mistress."
It does need to be pointed out that as energy rises with the square of velocity, doubling the orbital velocity increases the energy needed to reach that speed four-fold
If you can't use rockets why not build stairs from underwater? A stairway to heaven
