edit: i changed it ok so this video has been out for about a week now and a lot of the comments are mad at me for making clickbait, so i’m gonna try to clear that up in one comment when i was writing this script a few months ago, i had just gotten recommended a bunch of ai generated clickbait bs that inspired me to make this. I put “there are no habitable exoplanets” as the title as a direct response to the titles of the other videos, which were saying stuff like “these are the most habitable exoplanets” this video sat on the back burner for a few months until i finally got around to publishing it, and I didn’t bother to change the title the title is not arguing that habitable exoplanets don’t exist. I say in the video that they probably do. If anything I should’ve added quotation marks to the title (there are no “habitable” exoplanets) to make it more in line with what i actually wanted the video to say (which was meant as a direct counter to the ai misinformation that’s everywhere) but I forgot to do that, and overnight this became my best performing video ever, and now i’m scared to change the title for fear that the whole thing will just die my goal isn’t to misinform people. I actively try to avoid clickbait as much as possible, and I research my videos for months before publishing them. When I made this title, clickbait genuinely wasn’t even on my mind, “there are no habitable exoplanets” was just my first automatic thought (and if you check my other videos you’ll hopefully find this is true, my other video titles are usually very simple and non-clickbait. This video is very much an outlier) So sorry if you feel clickbaited, but that honestly wasn’t my intention. I had no intent of making the video clickbait, and at this point i’m scared to change it because it could kill the video’s performance, and I feel as though this is an important video to get out to as many people as possible, since it’s directly countering popular misinfo i’m not trying to make excuses, i need to hold myself up to a higher standard so i don’t become the exact thing i’m trying to stop, and ig i’ll just remember to revise video titles in the future essay over
I don't think you are making excuses but you are choosing to leave a clickbait title up at this point, even if not originally, to get money despite the fact you know that this is misleading. You do what you want but it is disheartening to see that you care more about getting money than being honest.
I don't think the title is clickbait. There aren't currently any habitable exoplanets that we know of. There are some that we think could be, but that's not helpful. Please don't change the title.
yeah, the reality is that Venus, Mars, type planets seems to be the norm in the habitale zone. It's like earth has all the elements needed. planets detectable to us requires large amounts of work to make habitable. I have my own personal propossal that would require alot of work. it would require using asteriod dust to blanket the plants surface. This would lock in the gases that causes the runaway green house. as many rocky worlds is missing a upper surface layer like earth. if mars had this surface layer, mars would be the size of earth.
@DarkMagicianGirl0 it really isn’t about the money for me if this was any other normal video i would’ve already changed it by now, even if it was getting as many views as it was. The difference with this video is that i’m trying to stop misinformation with it, so i feel like it’s more important than my other videos i really don’t make a lot of money from my videos yet so it’s not really a concern for me
@@PlanetGuy901but absolutely ZERO people died on those planets however entire species died on earth TL;DR: earth is the most deadliest planet in the universe
The funniest joke in the universe would be that theres another intelligent lifeform out there, but they see Earth as unfit for life because they think non-ammonia breathing lifeforms an impossibility.
There's actually a GIANT void in space that's roughly 330 million light years across with only about 60 galaxies inside of it. Depending on how much you know about space, that might sound like a lot, but usually around *2000* galaxies would take up this space. Anyways, I bring this up because I find it really strange just how empty it is. It's almost no way a coincidence. The main theory is that this void is just a lot of other voids merged together... But the other theory is that this somehow involves alien life far more advanced than ourselves, and that they've cleared out a massive section of space for whatever reason.
the three reasons we havent found habitable exoplanets: 1. theyre hard to detect because theyre far 2. we have to consider a lot of factors which slims the chances way too much 3. we suck at finding earth sized planets around other stars Update: WTF IS GOING ON IN THE REPLIES LIKE CAN YALL BE CIVILIZED
@@renatoherren4217you do realise that habitable planets arent required to be terraformed? if theres a planet with an oxygen atmosphere, water, and reasonable temperatures that doesnt mean god has come to physically change it
@@Flesh_Wizard You should watch the documentary extraterrestrial it shows a planet called Aurelia ( Fictional ) With alien life adapted to survive living near a red dwarf, It's pretty cool!
That's because current technology can only detect planets orbiting closely to their cooler red dwarfs. We haven't yet found a exoplant that orbits as far as Earth from the Sun.

AI generated "education" content on RUclips is genuinely a huge issue, and a giant tragedy. I sincerely thank you for noticing the issue and attempting to fight it off. I also entirely agree with your point. Do habitable exoplanets exist? I can say with near absolute certainty, that yes, they do But when our sample size of "well understood exoplanets" is like, 4, with everything else being basically guesses, of course we haven't found any Earth clones yet.
A lot of topics are getting overwhelmed with AI bullshit, be it long videos or shorts, and those videos get spammed with likes from bots so it has a higher reach The dead internet theory is no longer a theory
Heck I could say this, although we know such exoplanets exist with small possible clues of habitablity, we know little to nothing about them in reality. The same goes for fossils, we know how they looked like, but we'll never know thow they behaved in life.
@@JuniAkuHey there, I enjoy countryballs a lot, and unfortunately, all I get recommended is pure waste. Today I just got a video on my recommendations of Poland’s asscheeks getting slapped.

'Planets don't have to be habitable to be interesting.' I know it, you know it, everyone in this comment section knows it. But for the vast majority of people, they don't care unless it's habitable.
@@yalexander9432Currently mars during the summer reaches up to 20°C and did have liquid water at one point (keep in mind the sun was even smaller back when it did), so if it had an atmosphere like Earth it would probably not be completely covered in ice.
I dunno. I think certain anaerobic soil bacteria or the lifeforms that live at hydrothermal vents could find a habitable home off Earth. Evolution is driven by environment, and even here on Earth there are some pretty extreme environments, yet life finds a way. Which does further bolster your core point about different species having different standards.
That's not how it works though. Even the most basic lifeforms have a noticeable effect on a planet. Living organisms are basically chemical factories. Life is literally responsible the Earth's atmospheric oxygen.
Every living thing is undertaking chemical processes in one way or another. Oxygen itself is a byproduct of life. So if there's any alien life on these exoplanets, it would be detectable regardless of whether they're habitable or not. Unless if they're extremely primitive/new, and have an undetectable effect on that planet.
The sound that plays when you introduce a planet makes me think you're gonna talk about how your dad took you to see the city to see the marching band when you were a young boy.
It's really unfortunate, because most people who comment here either didn't read the pinned comment about the video's title or that they didn't watch the full video.
isn’t the end goal to reach those who have been misinformed? like for those of us who already get it yeah it’s entertaining but for someone who’s been fooled, even if this video won’t help everyone it’ll at least help some people
@goldencheeze yes, but being misinformed is "wholly different", as one would put it, than being borderline schizophrenic. There's a reason he has people attacking him for literally doing nothing but providing the factual information we know and giving his thoughts about the things we don't. People are saying he's a liar and made this video to "clickbait people for money" like it's a fuckin ActionLab video. I like ActionLab, but *that's* what clickbait is. Not a dude making a no frills video criticizing people making videos that *actually* clickbait people into thinking there are other planets we could live on.
I think Isaac arthur brought a good point if you think about it: What if aliens smell really bad? Like they breathe out or sweat capsaicin or even thiols (the chemicals that make skunk spray so bad)? What if they smell... Toxicly bad? As in, the chemical they emit, perhaps even pheromones, can straight up kill earth life. I mean heck, oxygen itself is deadly toxic to what used to be the dominate life forms on earth.
The problem with trying to find habitable exoplanets is that scientists can never really be sure that a particular planet is actually habitable. There's just only so much we can observe about any body that far away from us.
This is basically interstellar. There’s only a few planets and all the possibilities are against us. Yet, we’ll have to try… eventually - a leap of faith for the hole species
Some people are getting confused. He's not saying there aren't no habitable planets, he's saying we haven't found any yet. And may never find any. Or it might happen tomorrow. We just don't know yet. Sometimes "we don't know" makes people uncomfortable, but there's nothing wrong with it.
The reason people are getting confused is because he decided to title the video "There are no habitable exoplanets" It's the inevitable consequence of clickbaiting. People will react to the clickbait title.
"We don't know" is science's best friend. And then when we know, we do. It's not about popularity/politics, but objective truth. Reminds me of Don't Look Up lol.
Even if some of these far off exoplanets were seemingly habitable….. we’d have no way of getting there with the propulsion systems we have, nor do we know how to preserve biological entities even if we could travel at relativistic speeds!
I’m so tired of headlines screaming “NEW EARTH FOUND CLOSE TO US!” First, it usually at least 40 light years away (which is close astronomically but 50,000 years away with our current technology.). I have a feeling that bacterial life might be fairly common, but having bacteria is not the same as having intelligent life. (That requires an environment that is suitable to complex life, and that environment must be fairly stable - not given to extreme swings in temperatures.)
Probably the reason we didn't find any Earth-Like worlds is because we're not very good at finding exoplanets (yet). If you check an exoplanet mass distribution graph, you'll notice most of them tend to be massive, and there's almost none under earth's mass. Exoplanets that are not too large for life are pretty easy to miss.
Exactly. Our very best telescopes are just at the very edge of, in the most optimal conditions, being able to just about theoretically detect an Earth-sized planet. Some other commenters here have talked about how we've surveyed thousands of planets and found none habitable, but that really isn't an interesting statistic considering that we're not surveying planets fairly and equally. Hot, massive planets with tight orbits are extremely over-represented.
Almost all earth-sized exoplanets found so far orbit red dwarf stars, which we have now realized are very bad for life (frequent super-flares that strip away volatiles). But this happens only because telescopes aren't yet sensitive enough to spot earth-sized planets around bigger, more luminous G-type stars (like the Sun). The next decades will be so exciting! :)
@@drew8443The best candidate for life: K-type stars aka Orange Dwarfs. A hair bit smaller than the Sun but much more forgiving and friendly than Red Dwarf stars since they don't emit as much solar flares.
Yeah, I don't see this getting mentioned enough. The data collection bias is always something to keep in mind. The two main methods used depend upon either the relative masses of the star versus the planet or the size/luminosity of the star compared to the size of the planet, along with limited orbital angles. All including the planet's orbital distance. With the technology used to find exoplanets, the available data is heavily biased towards large planets. Especially those close to the star. Which likely rules out detection of many earth-sized planets unless they're near a small red dwarf. I rarely see this bias mentioned, but it's an important point to keep in mind. I think habitable earth-like planets are likely to be very rare but we're also not currently able to work with a full picture due to the detection limits.
Also to point out, earth wasn’t always habitable, we are just lucky to be alive in this time. Because back then the earth was ice, rock, helish volcanos, and just pure water with rocks. The other planets could also just be in those phases that earth was in.
What scares me is eventually when we find the PERFECT habitable planet, we'll discover it has an alien ecosystem that would kill us instantly due to no immunities.
if the answer to the fermi paradox is "all species are hostile supremacists who nuke eachother to death upon first contact" i wont be surprised, just disappointed
luckily or immunesystem has millions opun milllions of random combinations to protect us from foreign bacteria, so we would most likely be completely fine, and our immunesystem adapts very quickly so it would probably create a cure
Every news about outer space is just so depressing. No, we can't travel it. No, we can't reach habitable planets. No, we can't terra form planets. No, space is too big for us. No, this planet will kill you...
That's just space. A habitable planet is very unlikely. But that's just what we can measure here from our tiny little world. There are so many planets in the universe, it's almost certain there is life somewhere.
Well, at least you were born on the one planet where breathing doesn't mean your skin's melting! It's quite a privilege for us to find life depressing because of "bad news from space exploration" instead of finding life depressing because it's physically and chemically impossible to breathe lol
All of that is total BS. We've been traveling through space for 70 years now. You can "terraform" planets if you want to or make them smaller or larger or anything. Space isn't magic. It's the same matter and physics as here.
We all want answers and progress, but there’s plenty of progress to be made regarding space even if we can’t “physically move through it” with ease, due to our limitations. Keep that spark alive bro, there’s sure to be a similar avenue that peaks your interest! :D
About 2 years ago, I got in a spat with some random arguing that the AI generated images were the actual planet and what it looks like, after i told them we don't have the tools to actually see the true exo planets and what it truly looks like. This channel is such a breath of fresh air. I love it.

I think the reason we haven't found any viable habitable exoplanets is simply due to the lack of data we have. We've only been observing exoplanets for a little over 3 decades, with most of those planets orbiting perilously close to their parent stars (primarily red dwarfs), and/or are Gas Giants and Super Earths/Sub-Neptunes, mainly so because they are very easy to detect. We have little data on Earth-sized exoplanets orbiting Sun-like stars because they're so much harder to detect, due to their much longer orbital periods which makes it hard to verify their existence via transit methods (which is the most common method). Our exoplanet catalogue will continue growing over the next couple decades with more powerful telescopes, and as telescopes become more powerful and our observational periods grow longer we will probably have more data on habitable exoplanet candidates.
People also have a huge misconception in thinking we should know everything by now. It's arrogance, or hubris, to think we already know everything. I was told by someone once that we know everything there is to know about stars and studying them further would be pointless. To me, that's blasphemous because even if we think we know it all, we should still continue to research to ensure it holds. So to me, the primary issue is people think we can do way more than we actually can. The reality is we base a lot of our findings on a telescope that realistically can only see most planets as no more than a few pixels on a screen along side some very limited data. Many feel we should at least have identified every planet in the milky way and know for sure whether life exists at any given area. Fact is, we can't even confirm microbial life in our own solar system much less another solar system. Now, as far as intelligent life goes, yes, we definitely should have detected something if it were out there at least within a vicinity. But that doesn't mean they're not here either. It's a bit easier to tell with intelligent life since they can create things that are unnatural you wouldn't find anywhere else, also generate heat and potentially signatures in the atmosphere would be more dominant than early life / microbial life.
@WildWombats For someone to say that we know all there is to know about stars is complete ignorance. From what we know as the observable universe it's specilulated that as big as that is, it's barely a fraction of the rest of the universe we can't even see. The scale is just too large to comprehend..
And the James Webb might be the last big telescope we've put out in space. Cutting budget again. And then the is the Kessler syndrome. We're in kind of a hurry.
The G note that plays every time you talk about a new planet reminds me of when i was a young boy and my father took me into the city to see a marching band
the cold vastness of the cosmic void reminds me of staying up late as a kid and needing to turn on the thermostat to not freeze to death in wisconsin winter
Kepler-22 B has another downside. It's low density means it can't have an iron/nickel nucleus, which means it won't have any magnetic field and any life that'd form there wouldn't survive
It's kind of funny to me how many people say humanity evolved from this Earth, to be apart of the world, and stay on it until extiction, yet we legitimately go out into space to find other planets to survive on. Your saying, we want to, as a human being, supposedly created from nature itself, we wanted to go out into space, out of Earth? The same nature that we come from? Like what else are we looking for in space? Everything we need is on Earth, what other purpose beyond this world do we have to find? You ain't gonna find God in space, you can find Him here already.
People don’t seem to understand how insanely rare and specific the conditions that life requires are, and that’s just what we know definitively is necessary. Even earth couldn’t have supported life for most of it’s existence, a real habitable planet isn’t something there must be a bunch of that we’re just bound to stumble across eventually it’s amazing that even one exists
The funniest part is, literally no human does! With a reference pool of... literally one, we can't even begin to speculate how rare they are. Just that we've looked a lot, and haven't found literally any.
You have to remember how insanely big the universe is and what we’re able to observe. We can only speculate the number of galaxies and the amount of “habitable” planets there are. IMO there are planets similar to earth but we’re too far away to know, or it hasn’t been enough time for those planets to sustain the life just like earth.
"Even earth couldn't have supported life for most of it's existence" As I understand it, this is false. Earth is roughly 4.5 billion years old, and life has existed on Earth for roughly 3.8 billion years. It's true that _multicellular_ life is much younger than that, but even multicellular life has existed for roughly 800 million years. Life has existed on Earth for the vast majority of its existence (so far as we can tell, anyway).
@@Jaykey-mj2mp that is a very good point. However, technically it's habitable for them. And we do consider those things human so technically, it's habitable.

So far we've found: Piles of gas giants Giant balls of lava Irradiated wastelands Colossal rocks with crushing gravity Big Mars Big Europa Whatever that one carbon pulsar planet is There's so many things that need to go right to get a habitable planet, I'd wager there's only a few in the galaxy
@@jackturner8472 there is no way for us to know because we only have a sample of 8 planets. Your confidence in your own estimate makes you also a victim of the dunning-kruger effect.
@@Trolligi we only have samples from one, actually. We have 5,000 confirmed planets, and most of them have hints as to their composition. There are at least 100 billion planets in the galaxy, that would make earth like planets 0.01% of all planets in the galaxy. Which is still ignoring the fact that there used to be literal oceans on mars, and there may have been oceans on Venus. So that’s at least two chances out of our sample size of four (Nobody is counting gas giants as possible habitable worlds btw!) So actually, there are likely many more than ten million habitable worlds in the galaxy. I’d wager, you don’t know what you’re talking about!
We will probably gave to search through hundreds of thousands of planets to find one that is even vaguely habitable, we simply haven't looked at all that many in the grand scheme of things
It would make no difference if we found thousands. The logistics alone (via rocket propulsion) are absolutely catastrophic. Totally implausible in nearly every way imaginable. Even the creation of space stations "along the way" wouldn't really work. It's a simple matter of energies expended vs. energies gained; it doesn't add up to a net positive.
@@Novastar.SaberCombatI mean all you really need is a few thousand nuclear bombs or fissile saltwater and you can already send a ship to another star in a few decades. As we advance further things like fusion engines will be developed as well, not to mention Dyson Swarms being able to accelerate laser sail ships to drastically reduce the energy needed.
@@CarlosAM1the better option would be an engine that uses the controlled fusion of hydrogen atoms. Hydrogen is the most available element in the universe, and it's the easiest element to fuse. However, we are decades - centuries from this kind of technology being cheap and readily available.
@@landenmoudy5749 Yeah, those are the fusion engines I mentioned. Do keep in mind though that while Deuterium fusion with itself is possible it is most certainly not optimal, usually tritium + deuterium are used which are easy to ignite and can even be spin polarized to improve performance, however despite being an isotope of hydrogen tritium is extremely rare. Helium 3 also works but its crazy rare and harder to get going, spin polarizing is also not as effective here. Pure hydrogen-hydrogen fusion is so incredibly hard you may as well not even bother, at least not any time soon.

So much effort is put into finding habitable exoplanets, when we have a perfectly habitable earth that we’re not taking care of properly. No dream of space life is more important than protecting what we already have here.
I blame the issue of not detecting many earth sized planets around yellow dwarfs like our sun on Kepler mission 's short durations. We can barely interpolate datas to extract 3 to 4 orbits of this type of planets, which is the minimum for confirmation.
People might doom-post but... Let's be real, if it has a thick enough atmosphere and the temperature's good, I'm down. Just need to carry around your own oxygen. (and maybe some UV protection depending on the star).
While there might be a habitable exoplanet out there, such truly Earth-like worlds would be VERY RARE. Even if we do find life on other planets, their environments would probably be vastly different and hostile to life from Earth. And we don't know much about planets outside our solar system. We only know about their mass, size, and distances from their parent star(s). A big issue with most "Earth 2.0's" is that most orbit M type stars. Which are not only VERY VIOLENT, but also any planet that orbits them in their habitable zone would be tidally locked, meaning one side is an endless day, and the other side is an endless night.
A planet being cold is not necessary a killer deal for life, anyone traveling past in the cryogenic geological era when every surface land in earth was covered by kilometers thick ice sheets would have thought that earth is inhabitable, there was very few sign of life back then but life survived close to volcanic vents.
As per Keple-22 b: Habitable ≠ harboring life. A planet that could support our life but doesn't yet have any of its own would be even better than one already inhabited, since there would be no problems with the way both kinds of life interact. And life as we know it doesn't need volcanic activity, as long as it has some source of minerals, such as having them contained in the ocean. Inhabiting a planet with deep oceans that keeps useful minerals on the bottom would be an interesting challenge. We'd have to kickstart an ecosystem by supplying floating plants with mechanically gathered fertiliser until they could sustain lifeforms that could dig through the substrate and automate that process. Or engineer plants with insanely long anchor-roots and take care of them until they grow them enough to spread.
People also don’t take into account what part in time a planet is currently in. Remember, for the vast majority of earth’s life, she was completely uninhabitable and devoid of life. A billion years ago a hypothetical civilization could have gazed upon earth and said the exact same things we say about other planets. There was even a billion year time stretch where earth COULD support life but still had none. There were plenty of times where life was wiped out and plenty of times where it sprung up. Some of these planets could have been way past their prime or haven’t seen their prime. Or(which is more than likely the case), won’t have a prime at all. And I think this is vastly overlooked
I really appreciate this. It‘s hard to find quality space-related content online because people‘s approach to the topic is completely warped, ie: drawing interest from science fiction instead of viewing it in the same light as nature on Earth: simply appreciating it the way it is, not depending entirely on mystery to be interesting. I couldn‘t exaggerate how incredibly rare this is.
There are no "known" exoplanets that can definitively support life. That said, there are about 200,000,000,000 stars on each galaxy and about 4,000,000,000,000 known galaxies. We have a long way to go before we can definitively say we are the only ones
Hahahaha Ok little Johnny (Also habitable for us; If we haven't found it even in scans BEYOND the space shuttles' reach, we probably would never reach it when trying to get there)
If you understand statistics, you’ll be able to pull a probability on the existence of life on other planets based upon randomizing sample sizes on various populations. So it can be reasonable to say that if we parse through 5000 random galaxies and look at 1000 random systems in each galaxy and 0% of those systems have life on them or are incapable of sustaining life, then you can run a statistical analysis on those results and come to the conclusion that life is not probably anywhere else. When we run any kind of study at all, ever, we never study an entire population, but we look at a sample size, hopefully a good one, and then we calculate based upon that collected sample. So if you want to be consistent, that’s how we do things
I would like to consider the likely sampling bias effect in all of this. The fact is that it is much easier to find larger planets, because the gravitational effects on a parent star are more obvious. It is also easier to observe larger planets that transit red dwarf stars and orbit closely. That means that the atmospheres of these planets can be observed.. There are also just many more red dwarfs than sunlike stars.
Is there any good argument WHY we can’t be the only ones? We don’t know what starts or causes life when there is no preceding life. We could very well be the only ones
At first the title was “There are no habitable exoplanets”, now it is “There are no *known* habitable exoplanets”. Definitely a great change because the first one was very clickbaity and unconvincing.
How is it clickbaity? By calling out liars of actual clickbait-fueled AI channels?? Also if he was TRYING to clickbait; who would do a double take? The majority of people already think that exact first title. So it's not like "WAIT WHAAAAA?" It's the opposite of the garbage channels.
@@stupidmangoz I would. At least his points about the known "habitable" planets are fantastic. My problem is the previous title, which sounds implausible because I do believe that there are actually plenty of habitable planets, and habitability can occur in many ways more than just depending on the size, temperature and a star it orbits. Also also yes my reaction was "WAIT WHAAAAA?"
@@stupidmangoz It's clickbaity because no-one knows whether habitable exoplanets exist (it's statistically probable that they exist somewhere in the universe, but we won't know until we find one and are able to study it), and the video isn't even _about_ whether any habitable exoplanets exist, it's about the habitability of specific exoplanets which we know exist. How is making a claim in a video title, not even addressing it in the content of the video, and instead talking about a related but completely different claim, _not_ clickbait? "The majority of people already think that exact first title" The majority of intelligent people with basic awareness of the scale of the universe definitely don't.
@@stupidmangoz1.I love this video for this reason however that can still mean the previous title was clickbaity debukimg clickbait is not implied by the title (this isn't clickbait because it's not misleading) but that there are no habitable exoplanets(which is blatantly misleading) the video does not state that there are no habitable exoplanets rather the ones that we know problably can't actually sustain life if this is not clickbait then what is 2.this is contrary to your first point
@@stupidmangozI don't know what you're babbling about, but it's absurd to claim that there's no earth like planets even if you make "earth like" extremely specific.
One thing that haunts my mind is the idea that theoretically a planet could exist where all “life” has evolved to form a singular super entity, where weather is controlled like energy flowing through a body. An entire world rendered into a singular sentient celestial flesh orb built on top of a base of stone
What a vivid imagination you have, you should write a book about this concept because that's the craziest sci-fi alien "creature" idea I've ever read. But realistically how would such a "singular super entity" come into existence? Via technology? Would it be a digital or cybernetic merger? By conquest or consent or necessity or by accident? What technology would this "entity" possess? And what kind of "life" would this "entity" live? Does it sleep? Does it need food or water or just natural resources in general? If the entire planet if inhabited by this "entity" if it needs to eat, does it resort to cannibalism and eat itself? Or does it feed on the planet it lives on itself? Can this "entity" do photosyntheses like plants do? Is it plant like or bee hive like where it grows small "minions" to defend the main fleshy mass? So many questions!
@@SpinoRexy733 Those are all amazing ideas. What I tend to imagine is something that could come into existence at the extreme end of evolution. Perhaps it came about from billions of years of separate species of life slowly evolving in a direction where the need to have a simbiosis relationship with the other dominant life is more beneficial to survival than the need to compete like how it is on Earth, forming the ultimate runaway ecosystem perfectly tuned for collective survival. Or perhaps it is one highly evolved organism that began from the very beginning of life on that planet. Its source for energy would advance to bigger and bigger sources. Long structures burrowed deep into the mantle leaching thermal energy from the core. All oceans, lakes and rivers long gone, their water content used in circulation through vein like networks latticed throughout the global body. Chambers the size of continents that act as organs to regulate internal pressure and waste. Weather is generated in the body to serve the needs of transporting acids and proteins through out directed channels. Lightning bolts firing between massive neuron analogs and elsewhere in the body for energy transfer. And an external envelope that can harvest massive amounts of energy from the planets host star (or stars). It would have systems that can break down and sort material arriving from space. I imagine it would be sentient, but not in the traditional idea of self awareness, but in the sense that It would have to be processing massive amounts of information on a scale so large that rather than having thoughts and decisions, it’s “brain” layer would send signals to a nervous system for its body to function just like any animal, as well as help in guiding its evolution in an “informed” way. I also think it would have to be able to produce a complex network of defense mechanisms analogous to things like white blood cells and beneficial bacteria. And its exterior would need to be able to protect the body, and may be topped with a regulated external upper atmosphere film composed of the densest gases to help protect from harmful rays and cellular destruction. Hell, maybe it can take advantage of it’s gravity and orbit to have feelers like antenna that let the body react to solar weather or take advantage of emissions from other planets passing at the closest point in orbit, even though still millions of miles away, something this developed would find a way to exploit it. I believe that if humanity discovers one of these types of worlds there would be no reasonable way to attempt to directly land on it, and it would be incredibly dangerous to be anywhere in its body because of rapid massive respiratory pressure shifts, fluctuating air composition and extreme wind speeds, and huge amounts of raw electricity arcs constantly jumping between conductive surfaces through extreme atmospheric weather mediums, and there’s also bodily acids to worry about. And on top of that, we can’t be sure how the body would react to us being there. Would it ignore us? Or will it recognize our presence as a foreign object and seek to quickly destroy us? I’m really glad that you took interest in my idea. I’ve been thinking for a while about writing a story about the concept. I have one idea with a focus on how humanity would react to the discovery, and another idea of a solo traveler detailing his observations of the world and his emerging philosophical questions of possibility.
This raises the issue of the relationship between reporting on the findings science and the actual findings of science. Over reporting of what's happening in the scientific community is an issue that has been going on for decades.
EDIT: the word “known” was added but doesn’t matter. as someone who saw an AI copy THIS video right down to the thumbnail FOR CLICKBAIT and STEALING VIEWS, ALSO because i looked this video up BY TITLE because the title stood out to me… this is NOT clickbait and if it WAS clickbait it would be the ONLY okay reason to bait my click. the MAJORITY of youtube is clickbait BS and if i actually learn something respectable on the back end? THAT makes the video worth clicking. clickbait for views/ad revenue: ❌ baiting for clicks to spread knowledge: ✅
Of all exoplanets we've discovered, one of the best candidates for habitability is Kepler-442b. It is has around 1.34 times Earth's radius, it is unlikely to be tidally locked, and it orbits a K-type (orange dwarf) star rather than a red dwarf. Its equilibrium temperature is estimated at 22K colder than Earth, but assuming a similar atmospheric composition, the increased greenhouse effect due to the increased size of the planet would result in a similar surface temperature. Of course, it is still most likely that it's not habitable. We don't have any good estimates of its mass yet (likely around double the mass of Earth, but potentially similar to Earth mass or as much as 6 times the mass of Earth), so for all we know, it could be anything from a very small gas planet, or a "super-Venus", to an ultra-dense ball of mostly iron, though a composition similar to Earth is possible.
Habitable for us and habitable for life are 2 different things, but i agree none of these planets are probably habitable but they are still interesting and they probably wont kill us right away.
RUclips has been recommending me underrated gems lately. You are one of them. Concise and critical minded, digging away all the media sensationalism designed to generate clicks at the expense of nuance in this short attention span economy. Just mention temperatures in Celsius too
4:00 The problem with assuming temps of these planets simply based on distance to its star, we don't know if it's got thick enough atmosphere, or a moon big enough to cause tidal heating/ volcanism. A planet can be quite a bit warmer even farther out from its star compared to 'habitable' zone. Honestly the whole habitable zone is just an estimate based limited monkey science.
I think it says allot about humanity they we would rather attempt and fantasize about terraforming literal hellholes than simply take care of the rare paradise we already have
Funny how theirs now over 8.1 billion people on this planet but yet any thought of trying to attempt or fantasy about expanding beyond the Earth in any capacity must be disincentivized or labeled "impossible" now a days. Sooner or later space colonization is gonna have to be taken into consideration. If not for terraforming hellholes then living in spaceships like some city fleet's or something. But the entirety of the human race cannot be sustained on just the Earth alone forever.
Im so happy you made this video, I got tired of the hype, when even earth which is in the habitable zone had times when it was a complete mess, like snowball earth for example; being in habitable zone means nothing, you need to have mass, magnetic field, gravity, atmospheric pressure to sustain liquid water, and lets not forget a moon, not just any moon but a large moon to stabilise the orbit around the star, the star itself needs to be not so active, you also need to have couple of gas giants to protect you from asteroids and other left overs from creating of solar system.. So, so many things are needed to make a planet stable place for living creatures
"But we can terraform it!" Strawmanbro, we can't even terraform Earth. The technology we'd have to use to get from Earth to another planet though would be useful as that's where intelligent life's future is; between the stars, avoiding catastrophe, not sitting on a rock waiting for an extinction event.
Not in our lifetimes, but if humans survive for hundreds of thousands of years longer anything is possible. Humans will evolve, and if we ever do try to put a civilization on mars, while many will die humans will evolve quicker there as natural selection makes those that survive stronger and more equipped to live and withstand different atmospheres.
edit: i changed it
ok so this video has been out for about a week now and a lot of the comments are mad at me for making clickbait, so i’m gonna try to clear that up in one comment
when i was writing this script a few months ago, i had just gotten recommended a bunch of ai generated clickbait bs that inspired me to make this. I put “there are no habitable exoplanets” as the title as a direct response to the titles of the other videos, which were saying stuff like “these are the most habitable exoplanets”
this video sat on the back burner for a few months until i finally got around to publishing it, and I didn’t bother to change the title
the title is not arguing that habitable exoplanets don’t exist. I say in the video that they probably do. If anything I should’ve added quotation marks to the title (there are no “habitable” exoplanets) to make it more in line with what i actually wanted the video to say (which was meant as a direct counter to the ai misinformation that’s everywhere)
but I forgot to do that, and overnight this became my best performing video ever, and now i’m scared to change the title for fear that the whole thing will just die
my goal isn’t to misinform people. I actively try to avoid clickbait as much as possible, and I research my videos for months before publishing them. When I made this title, clickbait genuinely wasn’t even on my mind, “there are no habitable exoplanets” was just my first automatic thought
(and if you check my other videos you’ll hopefully find this is true, my other video titles are usually very simple and non-clickbait. This video is very much an outlier)
So sorry if you feel clickbaited, but that honestly wasn’t my intention. I had no intent of making the video clickbait, and at this point i’m scared to change it because it could kill the video’s performance, and I feel as though this is an important video to get out to as many people as possible, since it’s directly countering popular misinfo
i’m not trying to make excuses, i need to hold myself up to a higher standard so i don’t become the exact thing i’m trying to stop, and ig i’ll just remember to revise video titles in the future
essay over
I don't think you are making excuses but you are choosing to leave a clickbait title up at this point, even if not originally, to get money despite the fact you know that this is misleading.
You do what you want but it is disheartening to see that you care more about getting money than being honest.
Option one: change the title & risk losing some views.
Option two: Keep the title & gain the wrong kind of views.
Just my two cents.
I don't think the title is clickbait. There aren't currently any habitable exoplanets that we know of. There are some that we think could be, but that's not helpful. Please don't change the title.
yeah, the reality is that Venus, Mars, type planets seems to be the norm in the habitale zone. It's like earth has all the elements needed. planets detectable to us requires large amounts of work to make habitable. I have my own personal propossal that would require alot of work. it would require using asteriod dust to blanket the plants surface. This would lock in the gases that causes the runaway green house. as many rocky worlds is missing a upper surface layer like earth. if mars had this surface layer, mars would be the size of earth.
@DarkMagicianGirl0 it really isn’t about the money for me
if this was any other normal video i would’ve already changed it by now, even if it was getting as many views as it was. The difference with this video is that i’m trying to stop misinformation with it, so i feel like it’s more important than my other videos
i really don’t make a lot of money from my videos yet so it’s not really a concern for me

Star Trek has many examples of aliens that are not carbon based, non corporeal, breathe a different atmosphere, drink acid and so on.
There's actually a GIANT void in space that's roughly 330 million light years across with only about 60 galaxies inside of it. Depending on how much you know about space, that might sound like a lot, but usually around *2000* galaxies would take up this space.
Anyways, I bring this up because I find it really strange just how empty it is. It's almost no way a coincidence. The main theory is that this void is just a lot of other voids merged together... But the other theory is that this somehow involves alien life far more advanced than ourselves, and that they've cleared out a massive section of space for whatever reason.

Hot take: Those planets are not habitable by our (humans or earthlings in general) standards. Different species have different habitable standards.
It's just a fact.But here's another.No Planet is habitable for humans
I dunno. I think certain anaerobic soil bacteria or the lifeforms that live at hydrothermal vents could find a habitable home off Earth. Evolution is driven by environment, and even here on Earth there are some pretty extreme environments, yet life finds a way.
Which does further bolster your core point about different species having different standards.
That's not how it works though. Even the most basic lifeforms have a noticeable effect on a planet. Living organisms are basically chemical factories. Life is literally responsible the Earth's atmospheric oxygen.
True, i imagine some aliens sees earth as uninhabitable rock because they have different standards for life.
Every living thing is undertaking chemical processes in one way or another. Oxygen itself is a byproduct of life. So if there's any alien life on these exoplanets, it would be detectable regardless of whether they're habitable or not. Unless if they're extremely primitive/new, and have an undetectable effect on that planet.

The problem with trying to find habitable exoplanets is that scientists can never really be sure that a particular planet is actually habitable. There's just only so much we can observe about any body that far away from us.
This is basically interstellar. There’s only a few planets and all the possibilities are against us. Yet, we’ll have to try… eventually - a leap of faith for the hole species
Some people are getting confused. He's not saying there aren't no habitable planets, he's saying we haven't found any yet. And may never find any. Or it might happen tomorrow. We just don't know yet. Sometimes "we don't know" makes people uncomfortable, but there's nothing wrong with it.

Even if some of these far off exoplanets were seemingly habitable….. we’d have no way of getting there with the propulsion systems we have, nor do we know how to preserve biological entities even if we could travel at relativistic speeds!
I’m so tired of headlines screaming “NEW EARTH FOUND CLOSE TO US!” First, it usually at least 40 light years away (which is close astronomically but 50,000 years away with our current technology.). I have a feeling that bacterial life might be fairly common, but having bacteria is not the same as having intelligent life. (That requires an environment that is suitable to complex life, and that environment must be fairly stable - not given to extreme swings in temperatures.)
With the same AI voice
Yeah plus bacteria kills so if that’s the life then not impressed
True, but having bacteria means there's potential for more life down the line. Proof of bacteria on an exoplanet would be HUGE.
I bet they have cool alien looking creatures
Could life have evolved and adapted specifically for those environments -- ones which WE find inhospitable?
Probably the reason we didn't find any Earth-Like worlds is because we're not very good at finding exoplanets (yet). If you check an exoplanet mass distribution graph, you'll notice most of them tend to be massive, and there's almost none under earth's mass. Exoplanets that are not too large for life are pretty easy to miss.
Exactly. Our very best telescopes are just at the very edge of, in the most optimal conditions, being able to just about theoretically detect an Earth-sized planet. Some other commenters here have talked about how we've surveyed thousands of planets and found none habitable, but that really isn't an interesting statistic considering that we're not surveying planets fairly and equally. Hot, massive planets with tight orbits are extremely over-represented.
Almost all earth-sized exoplanets found so far orbit red dwarf stars, which we have now realized are very bad for life (frequent super-flares that strip away volatiles). But this happens only because telescopes aren't yet sensitive enough to spot earth-sized planets around bigger, more luminous G-type stars (like the Sun). The next decades will be so exciting! :)
If we would see our system from a different star we'd probably only really see the four gas giants and deem the solar system uninhabitable.
@@drew8443The best candidate for life: K-type stars aka Orange Dwarfs. A hair bit smaller than the Sun but much more forgiving and friendly than Red Dwarf stars since they don't emit as much solar flares.
Yeah, I don't see this getting mentioned enough. The data collection bias is always something to keep in mind. The two main methods used depend upon either the relative masses of the star versus the planet or the size/luminosity of the star compared to the size of the planet, along with limited orbital angles. All including the planet's orbital distance. With the technology used to find exoplanets, the available data is heavily biased towards large planets. Especially those close to the star. Which likely rules out detection of many earth-sized planets unless they're near a small red dwarf.
I rarely see this bias mentioned, but it's an important point to keep in mind. I think habitable earth-like planets are likely to be very rare but we're also not currently able to work with a full picture due to the detection limits.
Also to point out, earth wasn’t always habitable, we are just lucky to be alive in this time. Because back then the earth was ice, rock, helish volcanos, and just pure water with rocks. The other planets could also just be in those phases that earth was in.
What scares me is eventually when we find the PERFECT habitable planet, we'll discover it has an alien ecosystem that would kill us instantly due to no immunities.
Or even develop sapience...
Would you like to hear the good word of human supremacy?

That scenario can play out on any "habitable"planet! We could be the infection. We would have to tame the exoplanet anyway.....

I think the reason we haven't found any viable habitable exoplanets is simply due to the lack of data we have. We've only been observing exoplanets for a little over 3 decades, with most of those planets orbiting perilously close to their parent stars (primarily red dwarfs), and/or are Gas Giants and Super Earths/Sub-Neptunes, mainly so because they are very easy to detect. We have little data on Earth-sized exoplanets orbiting Sun-like stars because they're so much harder to detect, due to their much longer orbital periods which makes it hard to verify their existence via transit methods (which is the most common method).
Our exoplanet catalogue will continue growing over the next couple decades with more powerful telescopes, and as telescopes become more powerful and our observational periods grow longer we will probably have more data on habitable exoplanet candidates.
People also have a huge misconception in thinking we should know everything by now. It's arrogance, or hubris, to think we already know everything. I was told by someone once that we know everything there is to know about stars and studying them further would be pointless. To me, that's blasphemous because even if we think we know it all, we should still continue to research to ensure it holds.
So to me, the primary issue is people think we can do way more than we actually can. The reality is we base a lot of our findings on a telescope that realistically can only see most planets as no more than a few pixels on a screen along side some very limited data. Many feel we should at least have identified every planet in the milky way and know for sure whether life exists at any given area. Fact is, we can't even confirm microbial life in our own solar system much less another solar system. Now, as far as intelligent life goes, yes, we definitely should have detected something if it were out there at least within a vicinity. But that doesn't mean they're not here either. It's a bit easier to tell with intelligent life since they can create things that are unnatural you wouldn't find anywhere else, also generate heat and potentially signatures in the atmosphere would be more dominant than early life / microbial life.
@WildWombats For someone to say that we know all there is to know about stars is complete ignorance. From what we know as the observable universe it's specilulated that as big as that is, it's barely a fraction of the rest of the universe we can't even see. The scale is just too large to comprehend..
And the James Webb might be the last big telescope we've put out in space. Cutting budget again. And then the is the Kessler syndrome. We're in kind of a hurry.

"Even earth couldn't have supported life for most of it's existence"
As I understand it, this is false. Earth is roughly 4.5 billion years old, and life has existed on Earth for roughly 3.8 billion years. It's true that _multicellular_ life is much younger than that, but even multicellular life has existed for roughly 800 million years.

Which is still ignoring the fact that there used to be literal oceans on mars, and there may have been oceans on Venus.

Helium 3 also works but its crazy rare and harder to get going, spin polarizing is also not as effective here.

Good fucking lord what is wrong with you people
While there might be a habitable exoplanet out there, such truly Earth-like worlds would be VERY RARE. Even if we do find life on other planets, their environments would probably be vastly different and hostile to life from Earth. And we don't know much about planets outside our solar system. We only know about their mass, size, and distances from their parent star(s). A big issue with most "Earth 2.0's" is that most orbit M type stars. Which are not only VERY VIOLENT, but also any planet that orbits them in their habitable zone would be tidally locked, meaning one side is an endless day, and the other side is an endless night.

As per Keple-22 b: Habitable ≠ harboring life. A planet that could support our life but doesn't yet have any of its own would be even better than one already inhabited, since there would be no problems with the way both kinds of life interact. And life as we know it doesn't need volcanic activity, as long as it has some source of minerals, such as having them contained in the ocean.
Inhabiting a planet with deep oceans that keeps useful minerals on the bottom would be an interesting challenge. We'd have to kickstart an ecosystem by supplying floating plants with mechanically gathered fertiliser until they could sustain lifeforms that could dig through the substrate and automate that process. Or engineer plants with insanely long anchor-roots and take care of them until they grow them enough to spread.
I’m being attacked by the G note transition
People also don’t take into account what part in time a planet is currently in. Remember, for the vast majority of earth’s life, she was completely uninhabitable and devoid of life. A billion years ago a hypothetical civilization could have gazed upon earth and said the exact same things we say about other planets. There was even a billion year time stretch where earth COULD support life but still had none. There were plenty of times where life was wiped out and plenty of times where it sprung up.
Some of these planets could have been way past their prime or haven’t seen their prime. Or(which is more than likely the case), won’t have a prime at all.
And I think this is vastly overlooked
I really appreciate this.

(Also habitable for us; If we haven't found it even in scans BEYOND the space shuttles' reach, we probably would never reach it when trying to get there)
If you understand statistics, you’ll be able to pull a probability on the existence of life on other planets based upon randomizing sample sizes on various populations. So it can be reasonable to say that if we parse through 5000 random galaxies and look at 1000 random systems in each galaxy and 0% of those systems have life on them or are incapable of sustaining life, then you can run a statistical analysis on those results and come to the conclusion that life is not probably anywhere else. When we run any kind of study at all, ever, we never study an entire population, but we look at a sample size, hopefully a good one, and then we calculate based upon that collected sample. So if you want to be consistent, that’s how we do things
I would like to consider the likely sampling bias effect in all of this. The fact is that it is much easier to find larger planets, because the gravitational effects on a parent star are more obvious. It is also easier to observe larger planets that transit red dwarf stars and orbit closely. That means that the atmospheres of these planets can be observed.. There are also just many more red dwarfs than sunlike stars.

One thing that haunts my mind is the idea that theoretically a planet could exist where all “life” has evolved to form a singular super entity, where weather is controlled like energy flowing through a body. An entire world rendered into a singular sentient celestial flesh orb built on top of a base of stone
Why would this be scary.
working on it
What a vivid imagination you have, you should write a book about this concept because that's the craziest sci-fi alien "creature" idea I've ever read. But realistically how would such a "singular super entity" come into existence? Via technology? Would it be a digital or cybernetic merger? By conquest or consent or necessity or by accident? What technology would this "entity" possess? And what kind of "life" would this "entity" live? Does it sleep? Does it need food or water or just natural resources in general? If the entire planet if inhabited by this "entity" if it needs to eat, does it resort to cannibalism and eat itself? Or does it feed on the planet it lives on itself? Can this "entity" do photosyntheses like plants do? Is it plant like or bee hive like where it grows small "minions" to defend the main fleshy mass? So many questions!
@@SpinoRexy733 Those are all amazing ideas. What I tend to imagine is something that could come into existence at the extreme end of evolution. Perhaps it came about from billions of years of separate species of life slowly evolving in a direction where the need to have a simbiosis relationship with the other dominant life is more beneficial to survival than the need to compete like how it is on Earth, forming the ultimate runaway ecosystem perfectly tuned for collective survival. Or perhaps it is one highly evolved organism that began from the very beginning of life on that planet. Its source for energy would advance to bigger and bigger sources. Long structures burrowed deep into the mantle leaching thermal energy from the core. All oceans, lakes and rivers long gone, their water content used in circulation through vein like networks latticed throughout the global body. Chambers the size of continents that act as organs to regulate internal pressure and waste. Weather is generated in the body to serve the needs of transporting acids and proteins through out directed channels. Lightning bolts firing between massive neuron analogs and elsewhere in the body for energy transfer. And an external envelope that can harvest massive amounts of energy from the planets host star (or stars). It would have systems that can break down and sort material arriving from space. I imagine it would be sentient, but not in the traditional idea of self awareness, but in the sense that It would have to be processing massive amounts of information on a scale so large that rather than having thoughts and decisions, it’s “brain” layer would send signals to a nervous system for its body to function just like any animal, as well as help in guiding its evolution in an “informed” way. I also think it would have to be able to produce a complex network of defense mechanisms analogous to things like white blood cells and beneficial bacteria. And its exterior would need to be able to protect the body, and may be topped with a regulated external upper atmosphere film composed of the densest gases to help protect from harmful rays and cellular destruction. Hell, maybe it can take advantage of it’s gravity and orbit to have feelers like antenna that let the body react to solar weather or take advantage of emissions from other planets passing at the closest point in orbit, even though still millions of miles away, something this developed would find a way to exploit it. I believe that if humanity discovers one of these types of worlds there would be no reasonable way to attempt to directly land on it, and it would be incredibly dangerous to be anywhere in its body because of rapid massive respiratory pressure shifts, fluctuating air composition and extreme wind speeds, and huge amounts of raw electricity arcs constantly jumping between conductive surfaces through extreme atmospheric weather mediums, and there’s also bodily acids to worry about. And on top of that, we can’t be sure how the body would react to us being there. Would it ignore us? Or will it recognize our presence as a foreign object and seek to quickly destroy us? I’m really glad that you took interest in my idea. I’ve been thinking for a while about writing a story about the concept. I have one idea with a focus on how humanity would react to the discovery, and another idea of a solo traveler detailing his observations of the world and his emerging philosophical questions of possibility.
Theoretically, we could say that Earth is an entity like you just described. 😮😊❤

It is has around 1.34 times Earth's radius, it is unlikely to be tidally locked, and it orbits a K-type (orange dwarf) star rather than a red dwarf. Its equilibrium temperature is estimated at 22K colder than Earth, but assuming a similar atmospheric composition, the increased greenhouse effect due to the increased size of the planet would result in a similar surface temperature.
Of course, it is still most likely that it's not habitable. We don't have any good estimates of its mass yet (likely around double the mass of Earth, but potentially similar to Earth mass or as much as 6 times the mass of Earth), so for all we know, it could be anything from a very small gas planet, or a "super-Venus", to an ultra-dense ball of mostly iron, though a composition similar to Earth is possible.
Habitable for us and habitable for life are 2 different things, but i agree none of these planets are probably habitable but they are still interesting and they probably wont kill us right away.
"they probably wont kill us right away."
The Venus-like ones would.
I rlly appreciate you focusing your channel on real science and not clickbait, makes the subjects u cover so much more interesting
This just shows how much of a gem the Earth truly is.
Earth is so skibidi 🎉🎉🎉 EARTH SUPREMACY 🌎 😍 😫 😩
To us... Earthlings. Not to others.
@@keeganantony9745fuck em, we are cooler than them anyways
And we don't even care about it because we're destroying the environment with overpopulation and greed.
@@keeganantony9745 what others?
With such a small sample size; the idea that we've found a candidate that's even slightly likely to support life is extremely encouraging.
Exoplanets aren't going to adjust themselves to us, so we need to adapt to them
Or terraform
@@alexstromberg7696If we could do that, we'd just fix all earth's issues...
also doesn’t mean that other lifeforms need our exact needs to develop maybe they evolved to live with their planets conditions
@@shiro4095I mean if that was true almost any planet should have life then.
Yeah if we just drop 1 billion people into trappist-1’s atmosphere SOMEONE is bound to survive right?
Omg insta subbed. Finally a space channel that’s not boring, talking just to talk, woo or ran by AI. Thank god, actually.
RUclips has been recommending me underrated gems lately. You are one of them. Concise and critical minded, digging away all the media sensationalism designed to generate clicks at the expense of nuance in this short attention span economy.
Just mention temperatures in Celsius too
That one G note legit startled me i feel like a fucking sleeper agent
Bro hates fun and dreaming. Gotta respect it honestly, I’m subbing
he hates fun and whimsy 😭
Why does he hate dreaming
Let us dream grrrrrr
😡😡😤😤😤😤🤬🤬🤬
No he likes fun and whimsy, just based and can be implemented on practical reality.
i like how you underline what is actually cool about those planets, thanks for clearing up the misinformation
Also remember habitable doesn’t necessarily mean “habitable for humans” just that life “Might” be there
The biggest take away is that the singular piano note you're using makes me think about when I was a young boy.
4:00 The problem with assuming temps of these planets simply based on distance to its star, we don't know if it's got thick enough atmosphere, or a moon big enough to cause tidal heating/ volcanism. A planet can be quite a bit warmer even farther out from its star compared to 'habitable' zone. Honestly the whole habitable zone is just an estimate based limited monkey science.
Every time you hit that piano note i think *when u was, a young boy..."
I think it says allot about humanity they we would rather attempt and fantasize about terraforming literal hellholes than simply take care of the rare paradise we already have
Funny how theirs now over 8.1 billion people on this planet but yet any thought of trying to attempt or fantasy about expanding beyond the Earth in any capacity must be disincentivized or labeled "impossible" now a days. Sooner or later space colonization is gonna have to be taken into consideration. If not for terraforming hellholes then living in spaceships like some city fleet's or something. But the entirety of the human race cannot be sustained on just the Earth alone forever.
Im so happy you made this video, I got tired of the hype, when even earth which is in the habitable zone had times when it was a complete mess, like snowball earth for example; being in habitable zone means nothing, you need to have mass, magnetic field, gravity, atmospheric pressure to sustain liquid water, and lets not forget a moon, not just any moon but a large moon to stabilise the orbit around the star, the star itself needs to be not so active, you also need to have couple of gas giants to protect you from asteroids and other left overs from creating of solar system.. So, so many things are needed to make a planet stable place for living creatures
Why do you play the first note of Welcome to the Black Parade every time a new planet comes up
why not!
MCR MENTIONED RAHHHH🔥🔥🔥🔥
"But we can terraform it!"
Strawmanbro, we can't even terraform Earth. The technology we'd have to use to get from Earth to another planet though would be useful as that's where intelligent life's future is; between the stars, avoiding catastrophe, not sitting on a rock waiting for an extinction event.
Isn't the issue that we Terraform Earth by accident? We doubled CO2 concentration, changed large parts of the Ozone layer
We will never even get to them. The space between systems is too vast to traverse, even at light speed which is impossible to get too
Are you so sure about that?
Not with that attitude!
fear not, i am currently building a ship for this
Not in our lifetimes, but if humans survive for hundreds of thousands of years longer anything is possible. Humans will evolve, and if we ever do try to put a civilization on mars, while many will die humans will evolve quicker there as natural selection makes those that survive stronger and more equipped to live and withstand different atmospheres.
every heard about a theory about wormholes?
