did someone say moons?
I was thinking of you and your team when I saw this title!
Speak of the devil, I was just watching your grabby aliens video yesterday, excellent work as always :) How goes the exomoon hunt?
My money is on moons only exist in our solar system 🤑
You just have to say Exomoons 3 times and Cool worlds’ David Kipping turns up … ;)
@CoolWorldsLab I love your videos, you're someone i'd love having conversations with if i worked in the same field
Isaac, thanks for your frequent episodes!
A good video on a Fermi Paradox topic I never really hear about.
Wonderful work, Isaac.
I'm all about that future compendium of filters, looking forward to it
Heard of this topic a few times, but always as an example off a list of possible solutions. Was wonderful to dive into a fresh new filter.
32:50 A minor mistake here, while complex animal life didn't transition to land until roughly 430 million years ago (oldest fossil, although there are tracks dating back a couple tens of millions of years before), life itself had transitioned to land long ago. We have evidence of algae living on land close to 1.2 billion years ago. We also have paleofossils dating back to 2.2 billion years ago (which require biological activity to form), and even a controversial fossil of something resembling a fungi or plant of macroscopic scale from that same period, dubbed Diskagma. This raises the possibility of complex biospheres not necessarily taking ~4 billion years to develop. Bacterial presence on land is likely to be even older, maybe even more than 3 billion years.
Does that matter? Life only took a serious leap forward 600 million years ago. Even if what you say is true. It would mean that on earth in the beginning life evolved real slow. Giving it another possible Fermi paradox factor. And changing nothing on the outcome
Or maybe that's still fast who knows. Which isn't good news on finding life as it has smaller window to evolve on other planets
HAPPY ARTHURSDAY EVERYONE!
Just wanted to say I appreciate your consistency my friend
The first rule of combat: Where the heck is everyone?
It's no fun just fighting yourself
The first rule of combat is don’t go looking for a fight
A thing worth considering, when thinking about early climate on Earth, is that from time to time we appear to have had ring systems for a few hundred thousand years or so at a time, until the moon's gravitational influence sweeps them away. Since a ring casts a shadow on the winter hemisphere, this is strongly implicated in ice ages - and the moon strongly implicated in getting rid of them and enabling Earth to emerge from those ice ages in a timely way.
source?
@@fobusas there is new paper about this, "Evidence suggesting that earth had a ring in the Ordovician"
@@P1XeLIsNotALittleSquare i've read the summary. and it's problematic.. Even authors admit it.
" We further speculate that shading of Earth by this ring may have triggered cooling into the Hirnantian global icehouse period."
Also, it's Ordovician... Nothing to do with the last Pleistocene ice ages. starting 2.4M years ago
Though the rings could not have caused all Earth's ice ages because the rings would have been relatively short term.
@@Libertaro-i2u comment implied otherwise. And study openly admits it might have caused 0 ice ages. So at best it seems like a minor factor
It is probably one of the critical reasons why we exist.
There are so many small factors that go into us being here today. The idea that some other planet had this type of good luck, it is beginning to seem almost impossible. We must never forget the five major Extinction events.
Hubo más que solo 5, esas son las clásicas, a medida que pasa el tiempo se van descubriendo más indicios de otras grandes extinciones
@@RandomGuy-lu1en but when you throw in all the other probable conditions necessary, the odds against far out number the planets in the universe. (I could be wrong)
@@RandomGuy-lu1en Even with wiggle room, It's not even close.
It's a simulation....
We are an elaborate simulation. If the Mets lose today, I'll know for sure.
Definitely the moon makes us what we are, with relatively stable climates thanks to it. Life itself probably does not require such narrowly defined stable conditions, complex and intelligent life might. But life finds a way to deal with less favourable scenario’s, that this scenario works for us, doesn’t exclude other options too, such as the one featured in Avatar by James Cameron.
Such regular doses of brilliant content! Thanks again mate 😁
Step One: See that there's a new SFIA video
Step Two: Upvote new SFIA video
Step Three: Watch new SFIA video
"LaGrange Point Drifters" would be a great name for a future C/W band! 😄
I wonder how our recent discoveries regarding deep biospheres would affect chances for extraterrestrial life 🤔
Would be a great video topic I reckon
Isaac, when you make your filter compendium, I have two suggestions. First, mention relationships between filters, such as axial tilt and the presence of a large moon.
My other suggestion is to give your opinion as to the strength of the filter in terms of the odds of surviving it/passing it given as the order of magnitude of those odds. For instance, if you believe a filter is between 1 in 100 and 1 in 10,000, you would say it is between a 2 and a 4. If this idea hasn't been proposed before, may I suggest you call these Lon numbers or L numbers? 😁
An advantage of L numbers is if you have no idea if the filter is real or it is so powerful that you guess it could be as hard as 1 in 1,000,000,000,000 to pass, you would say it has an L number between 0 and 12. Another advantage is if you have an equation for calculating milestones in development, you can plug in L numbers in the various exponential terms to see how a set of filters might change the overall picture.
An L number takes into account both the odds of an event happening (or not) and the odds of surviving/passing that event, but in practice is just the better of the two. For instance, if avoiding an ELE asteroid collision is 1 in 1000, but surviving it is 1 in 100,000, the L number is 3, since avoiding the event is easier than surviving the event (I have no idea if this is true for this example).
The L number isn't always constant, but rather depends on the milestone in question. I assume most L numbers you will cite are for a given world reaching detectable technology, but they can be adjusted for different questions, such as the odds of a world developing life recognizable to a visitor to that world.
Feel free to play around with this idea. My current writing doesn't intersect with the Fermi paradox too strongly, so it likely will be some time before I can use it.
Isaac, my first wife, who heard your video voice and declared you were "adorable", passed away 2+ years ago. It's been about that long since youtube suggested your videos to me.
"Life forms producing it as a waste gas" hahaha we are breathing farts
"Pumbaa, with you, everything's gas."
Genuinely makes me so glad to see a recent SFIA video without AI "art" plastered all over it. Please keep this up, it both looks so much better aesthetically with the 3d graphics with real effort put into them, and makes me feel better about supporting the channel
I've gotta agree with this. AI art is insultingly lazy, always.

@@danguee1 Oh! it's an abbreviation for Science and Futurism w. Isaac Arthur
And I know they’d be plenty sf artists happy to contribute older works- with a nod to them of course
if we stripped mined both of Mars's moons and a bunch of asteroids to help build a new moon around Mars how big would it have to get before we see a positive impact on mars from the new moon?...has anyone looked into that kinda mega project yet
A lot, we discussed that in detail on or episode on the Martian Moons last year. Mars is probably a better candidate for para-terraforming
@@isaacarthurSFIA i'll have to go back and look thanks
Before watching, betting on two points
1) The moon os needed to create tidal pools and shore lines, maybe catch some impactors, keep the Earths magnetic feild going by passing rotational energy, etc
2) without the moon, civilizations even as advanced as ours never look up at the night sky. And they certainly don't have access to the massive material base of the moon for space industry. Imagine if the first manned mission wasn't the moon, but mars. We probably wouldn't go for another century at best. Lots of extra social suicide time
We don't actually know that life evolved in tidal pools and the moon is irrelevant to whether a civ looks up at the sky. stars still exist and have been a culturual and religious focus since time immemorial.
Not having a moon-sized industrial base right nearby is a nuisance, but we have quisimoons and temporarily captured or near-planet asteroids aren't exactly rare.
100yrs is quite frankly irrelevant on FP timelines. We certainly don't have the capacity to wipe out humanity here on earth. lk even all the nukes at the hight of the cold war wouldn't be even close to enough. would definitely set us back but definitely not the guaranteed existential threat that its usually portrayed in fiction.
@@virutech32 We may not know life evolved there, but I'm fairly certain the terrestrial life is believed to have first transitioned through tidal pools.
I agree people have always looked at the stars, obviously, but I don't think it's correct to say the moon is irrelevant here. It's a very important part of the night sky, the only object the eye can make out any details of, and it changes on a nightly basis.
The fact we've been to the moon in the 60s but never visited the other objects mentioned I would argue is evidence in the difference in difficulty. Temporary capture also isn't particularly useful. I'm sure a society would be forced to capture an asteroid if it wanted to develop without a moon, but that's a much more difficult proposition - failed attempts may be a filter on their own.
On time lines of successful civilizations, yes a hundred years is nothing. But in terms of filters it could be very significant. We might not be able to kill everyone, but having stripped all the high EROI oil and much of the coal you don't need to level a mountain to access, along with most of the higher grade ore deposits, makes me skeptical an industrial civilization could be rebuilt repeatedly.
Not to mention moons reflection of light back to earth. Everybody knows the difference between a full moon and a moonless night. I'm certain it influenced evolution pretty heavily.
@@neolithictransitrevolution427 By the time anyone had the capacity to even think about going to space we also had telescopes that could other planets. not saying the moon isn't extremely helpful but it isn't any kind of dealbreaker.
Also fossil fuels have never and certainly aren't currently necessarily for industrial civilization. We have renewables and nuclear and tbh neither is particularly difficult, especially when the environment is already trashed(tho not contaminated cuz thats just not how modern nukes work). Again they are convenient when ur starting from scratch, but A: we would not be starting from scratch & perhaps more importantly B: we would have access to ore deposits more concentrated than anything our ancestors could have hoped for. Every landfill and city becomes a mining site. Its not like we made elements disappear. Most were instead concentrated and brought to cities and factories. The few rare earths that have been diluted were not in karge use when we began space travel orn industrialized.
Also also just because some things might be a bit more expensive doesn't mean we can't extract them if we have to. we have litterally tens of millions of years to refigure it all oout.
Getting "nuked back into the stone age" is almost entirely a doomer fantasy.
@@neolithictransitrevolution427 By the way isaac actually has a video on "Cyclic Apocalypse"
This is one I think about a whole lot for years and glad you did a vid on it. You pretty much nailed every point that rattles around the ol noggin. Thanks as always IA and might I say there was some lovely wordsmithery in this episode that brought a smile
You really waxed lyrically!
Luckily I took the day off work 😁 cheers Isaac
Loved this one! I love pretty much all of these. But I love this one too.
6:28 I would love to read it 📕
It will be interesting to see going forward how “Earth like” planets and moons which are tidally locked, develop in terms of habitability for life
Its amazing to think the moon could have saved us from being Bigger Venus by blasting off most/all the native atmosphere
Very interesting! If the “wet/dry” cycle theory of life originating is true, then a large moon creating consistent tidal forces is absolutely a necessity for life, or at the very least a major benefit.
Then also as a deflection of or guard against asteroids.
2:28 As there are various disks of orbit, there are more than one way of producing them, which strongly affects this whole discussion.
There is a book about that written by an Astronomer. I don't recall his name and I no longer have the book but he went over some reasons he suspected that mankind might not exist if there was no moon.But that was a long time ago.
It certainly seems to be one of four or five major necessities
I was just thinking about this- the moon has a large effect on the earth, and it came about by such freak accident- it would make a good explanation for why life is so rare that we havent found any yet.
Yes but how often does such a freak accident occur?
And is a large moon absolutely necessary?
These are the questions that really determine whether this is a good reason for life to be rare.
The collision that caused its formation could be a relatively common occurrence in early solar systems.
Thank you for making Nerd Art Sunday another winner.
Our pleasure!
I had to think about LHB for a moment; I'm so happy this channel treats us as intelligent and informed consumers of science tube content!!! 8-P
A lot of research for this. Thank you for the information.
Nice music, nice videos you are a source of inspiration.. thank you ... i hope you might do a cinematic version of even higher quality one day
Been happy with my Henson razor for months. Bit of a mix up with the initial purchase and trying to use the code. Easy to kiss the code input before it’s too late.
I like this sort of topic. Reminds me of the Asimov book Robots and Empire, where the character Mandamus speculates on the unusually large size of Earth's moon as being a factor in Earth's development, (tangentially touching on Fermi Paradox matters - that you've not really gotten into here, which I'm a bit unhappy about, as I found them fairly compelling while reading the book. Though perhaps it's a good thing as this means you've not provided a spoiler for that book...) Not that Asimov necessarily got everything right in the book, but I think that - despite your assertion that there are a lot of other large moons out there - he got that right. Pluto has Charon, but other than that, no other moon in our system is anywhere in the size of the Moon - as compared to it's planetary body. Sure Ganymede et al may be that size or larger, but not in comparison to their host planet. (Mandamus goes on to use that large size of the Moon in his dastardly plan, but I'll leave readers of this comment in suspense as to how - you'll just have to read the book! And, may I recommend reading that series in order - The Caves of Steel, The Naked Sun, The Robots of Dawn, Robots and Empire, and Robots and Earth. It's a great series, and leads in to his famous Foundation series (set much later, but in the same universe.))
What If Our Sun was ejected from the Milky Way Galaxy or left and became a rogue star
Basically nothing happens. I mean sure the ejection event would probably wreck the solar system, but there's not much difference between our solar system being abrogue vs being in a galaxy
Not really a problem
No real issue whatsoever except for the night sky having few naked eye visible objects.
maybe less protection from intergalactic radiation and events 🤷♂️
@@tturi2 in the voids between galaxies? "Events" and radiation are both going to be more common in galaxies than outside of them. Going to a place where fewer things exist is safer than being in a place with lots of stuff there.
System change: Mass accretion, by any means, will modify gravitational effects. I'm aware that "1 comet per month" is tiny on human scales, but huge over megayears. (960 comets per human lifetime vs 12 million comets per megayear.)
Commenting to feed the algorithm 🙃
Is there an editing problem/repeat around 5:30 and 6:50? In around 6:25 can also see some jump in the subtitles and odd skip. Good video though!
*RAZORS with water soluble strips behind the blade(s) change the angle of incidence between the skin and blade, as they dissolve, rendering the shave painful and useless.* If only the blades were easy to clear out in water, and there was no water soluble strip to make us think that the blade's have lost their sharpness.
Okay. Who else heard Large Moons/Fermi Paradox and thought of Brethren Moons from Dead Space?
That's preferrable alternative to large moons meaning 'hefty Xibitionists'
there goes my f*#%! timeslot which was supposed to be productive
Appreciate ya. Thanks for sharing.
Been waiting for this one for awhile. ❤👍
I could see aquatic life performing things that won't work underwater in air bubbles or at the surface. And using things like heat vents.
Love when the moon shine's!!;)🎸✌️🪖📡🫙🗽👾👾👾👾🪕
Thanks Isaac anthur for sharing this idealisms movement about reseach and surveys they did
Hey Isaac I have a question about generation ships and communication with them couldn't they just drop satellites when / before signal starts dropping to keep the communication tame down to a few minutes give or take rather that several hours or longer? That way data could be transferred
The exact mechanism by which the moon is connected with the planet is a potential late filter. If you have a scenario where the moon's stability is linked to, for example, a koi fish swimming in a pond at the planet's North Pole, a power-crazed admiral might kill that fish, thereby destroying the moon and ending all life on the planet. Over sufficient time scales, it becomes virtually inevitable that someone will kill the fish, meaning that this filter is a very serious hurdle to get past.
I'm surprised this one hasn't come up a lot earlier.
The moon minimises procession, creates tides on Earth's surface and keeps the core hot.
The first allows large plants to evolve that exist long-term in fairly constant temperature zones. This also gives criters bigger than algae blooms to evolve without being frozen / heat blasted at regular intervals. This effect is a lot stronger than Isaac gives it credit for. 45 degree tilts rarely occur on earth as they do elsewhere.
Tides also allow environments to exist at the margins between land and water that allows water creatures to evolve and migrate onto the land.
But keeping the earth's core hot is vital to keep the magnetosphere going to protect us from the Sun's radiation.
The big unknown is tectonic plates - if these were created by a collision with Thea then it is clearly vital
I should also note that Jupiter and Saturn creating a stable resonance also helps by by gobbling up the asteroid bombardment.
Mars has two moons and Venus zero. On average one moon per planet.
Not true.....
The average would be all moons totalled divided by the 8 planets.
It's more like 10+ moons per planet (dominated by the gas giants with many moons).
Moons is not the issue here. Sure there are a lot of moons in our Solar System and that would imply there are moons in other systems. The issue is not moons but the size and density of our moon in comparison to our planet size. Even though moons such as Ganymede and Titan have more mass than the Moon they are much less dense and have weaker gravitational fields. Our Moon is truly unique and is a huge factor in the evolution and development of our planet. This is rare (nonexistent) in our Solar System (only Earth) and is likely very rare in other systems. Considering how much of an effect it has on our ecosphere it is a factor to consider.
Mercury: "Am I a joke to you?"
Do you have a moon?
If you average over large moons (relative to their planet, so we can include Phobos and Deimos), the average is more like 9/8. Excluding P&D, it's more like 7/8. So still close to 1 large moon per planet.
Of course, that's an arbitrary cutoff. 7/8 feels less arbitrary than 9/8, just because of the huge mass gap between Triton and all the smaller moons. But 0.875 and 1.125 are both close enough to 1 for the comment to work....
... Sorry, I was thinking about messing with the IAU's planet definition again yesterday, so still remember how a cutoff for subplanetary-mass moons Vs not-so-lunar satellites, and asteroids Vs meteoroids, got so much harder to put a concept-fence around, and that's making this comment way less pithy than it was meant to be.
About the formation of the Galilean moons and the assertion that they may be captured bodies, this somewhat strikes me as odd, since the other example of a system with orbital resonances: Trappist, is most likely just formed that way even if it’s planets got pulled in a tighter formation since their creation… such a neat system as Jupiter most likely can just act as its own little solar system, no captures required, or am I missing something that makes a capture scenario more likely?
23:24 that sounds a bit like you are suggesting that Neptune, named after the Greek god of the Ocean, might have been responsible for supplying earth with enough water to form out current oceans. If that were to turn out as fact, we might have accidentally named that planet incredibly fittingly.
did the moon play role in volcano / geothermal activity in oceans?
Thank you for the Moment of Enlightenment! Odds Are.... Life is going to be on more MOONS than planets.
O'Neill Cylinders dont require moons.
Double iron core for cosmic-ray and solar wind mitigating magnetic field, impactor sweeping satellite, enough tidal force to create regular large tides. Yeah, we kinda needed the Thean impact to make Earth habitable.
About that commercial my dad has one like that in his house and I had occasion to shave with it a few times, it doesn't change the fact that you are using just a steel razor as the blade it still very sharp and very easy to cut your face with it, and using after shave cream is must have with that other vise your skin will be red and itchy.
If you think there's a lot of rocky exoplanets, imagine how many Rocky moons are in the universe
27:32 i think there's a correction here: the axial tilt could easily have rolled as much as 180 degrees very suddenly as days got longer. It's way more likely than not, and when it did the poles would be stretched out while the old equator pancaked in, then all again when the planet rolled out back into its rhythm.
That alone could even have been the big push that got plate techbonics in motion too.
Total tangent, I'd love to just point out how awesome it is that our planet's life needs stability and much of the ebbs of seasons of days, and still maybe further eons of seasons of days lol. You'd think it'd be easier to evolve these special brains of ours without all the social stressors.
I sometimes wonder if it's a good idea to build a city station in some kind of areosynchronous orbit, using Phobos and Deimos as part of the radiation shielding. That would remove them as obstacles.
It would be a wise move for potentially destructive terraforming efforts, telecommunications, and normal economic activity between Mars and its satellite colonies, businesses, and Earth. It would be an excellent backup plan if it turns out that Martian gravity is not good for human and animal development, leaving that city as the only habitable Martian colony.
I suppose I'm now wondering how big such a city station would have to be in order to affect Mars for the purpose of terraforming, and maintaining desirable environmental conditions? Would it need to be as big, proportionately, as the Earth-Moon system? What orbit would be most beneficial? What effect would this megastructure have on Earth? Should we leave such an experiment for when/if we colonise another solar system? How much does an average/large sized city on Earth weigh?
I wonder how likely it would be to hollow out a small rock , 30 meters long , and make it look like a mini moon-thing , that's just "visiting" .
Like the mini moon-thing going on now?
And then a way to decided to make contact would be if they figure you out.
"Ok, y'all found me. How you doing? My name is 1st of my family. What's yours?" Lol idk. 😊
I hope our first contact is with a fungal alien. Why, you ask? Because I know he'll be a fungi.
was Jupiter involved in collision that led to earth and moon?
The amount of energy needed to migrate a planet the size and mass of Jupiter from 1.5 AU out to 5AU is unimaginable. Where do we believe this energy came from? And why didn't it throw the earth out into deep space? I can't find a decent explanation of this.
19:48 "I should note that the Moon being made from a collision is still simply a theory"
Evolution is simply a theory. Gravitation is simply a theory.
Though I know what you mean, I really think you should be more careful.
Still, great as always. Thank you.
helping Mars to capture and collide with Ceres could do for Mars what the Theia turned Moon did for Earth?
I wonder what would the universal ratio of exoplanets which have exomoons turn out to be. Whether it will be more or less than 75% which is the case for the planets of the Solar system.
I can't see how the enormous relative size of our moon to the Erath is not a very large factor on it's influence, and would be, on lies development? The fact that Jupiter has similar size moons is not remarkable because they are tiny relative to Jupiter's mass. The effect of Jupiter on those moons chance of producing life is certainly likely, but it would also create a lot of other problems too. Perhaps these two example of moon/planet disparity (one very large prime and tiny moon(s) and one large prime and very similar proportioned satellite should be taken and considered as very different for their effect on the question?
The absence of this term enquiring of moons of 1% mass from the Drake Equation represents an oversight that should render our existence on this planet impossible under the laws of physics. This real estate was developed to situate a moon.
Earth is The Moon's moon 👾
But that would be an insult...
to the Moon.
I thought the Galilean moons formed in a disk around Jupiter in an analogy of the planets.
there must be a filter that is close to 100%.
could be that filter is some kind of epiphany that life is pointless and every species eventually just stops breeding and allows themselves to die out.
Hermitcraft said it best.
"Moon big."
What if the Earth's moon after reforming being a mirror image of the Earth, having an atmosphere produced by the evaporation of the water covering its surface and developing microbiol life which didn't have enough time to become complex life because it couldn't hold onto its water, A fermeparadox of how life needs to fully deleope into a space feering species before their planet or moon become unhabitable
Do Jupiter or Saturn give off enough IR energy to be useful for solar panels on a moon in their orbit
Not really.
Nah, the Sun is still vastly more energetic at that distance. Except maybe in terms of reflected light for their very closest moon, I suspect not but I'd have to run the numbers, we talk about it a bit next week in colonizing Io but Io is still moon #5 from jupiter.
@@isaacarthurSFIA Io and Europa are probably too irradiated to ever be viable places to settle.
Given all of this, if an alien civilization finds us they probably are pretty awed we even exist.
I recently went down a rapid hole on the nuclear isotypes found on mars that would indicate a nuclear explosion tens of millions times bigger then tsar bomba.
I suspect that's an artifact of cosmic rays
Can Theia really be a dwarf planet when it's the size of Mars?
Life is different proposition than advanced life, and advanced life is entirely different proposition than civilizations. There are significant filters to just life, a lot more filters for advanced life, but the filters you're looking at for civilizations are almost prohibitive. If we lacked hands we would not have this one, for example, and that's a small and largely random early morphological change. We have hands because we allegedly developed in forests. But if you look at the thousands of other species who also developed in forests and did not end up like we did just in the one place we know for a fact life exists, you're beginning to get some idea of why the Fermi Paradox isn't a paradox. It's just projection, which is what humans have always done when faced with the unknown.
Since we're evidently doomed to project ourselves onto the Universe rather than just explore it, I project that humanity will spend the next billion years finding 99% bacteria, 1% alien jellyfish.
MOONS are going to be MORE ABUNDANT than Rocky Planets. 😊 I'm correct ain't I 😊
it's "Theory Changing Time", that's my new opinion.
There's more MOONS in the universe than planets obviously. Think about it, as a numbers game. Everything is a Numbers Game, and somehow I've never put it together.
There was already colonize Io episode?
Could a large moon be a habitable?
I believe the moon was caught, not made by collision
32:57 I'm sorry, but this animation is too distracting. LOL
Yeah its a weird one, though amusing, unfortunatetly there are darn few animations showing evolution so I use it more than i'd care too :)
That reminds me Moons from Doom games... 😏
i always think, the universe is not here and like it is, just because we like (or need) it this way... we are here cause the universe is how it is and we just enveloped our way... i guess without a large moon, no jupiter or something else we would be totally different but maybe we would have a Great filter that make life impossible, like a giant Moon or Jupiter or something else...
we still assume with the Filters that we are the base model, and all has to be almost the same or close to us and i am still unsure if this is just bad thinking or habit since the day of first european sailors...
What if somethings are not a filter but a bonus, moon = bonus
The singer Bob Dillon had a song where he says, "God is playing marbles with His planets. " Dillon was right...

Actually chemistry is physics, but I hope you understand me...
As a physicist I take exception to that, of course physics is more important :)
@@isaacarthurSFIA I know, I know, chemistry is based on electron shells and atomic mass and density.

It seems like the more we learn, the more early filters we become aware of. And we are far, far from knowing everything. That suggests by the time we do, the best estimate for habitable Earth odds are very, very low. And don't me started on multiple reasons why there are two late Great Filters that are in combination unavoidable, these being the problem of stupid people, and the limitless capability we have to create more and more destructive technologies far faster that we can acquire the wisdom to mitigate them. Sentients are compelled to invent new filters without end.
Technically right now earth has two moons for a couple of weeks.
