Even then we've obviously faced cataclysmic events which have ALMOST wiped out all life but its far less than what other systems would likely face.

Humanity is by far the strangest thing in our solar system. I remember a comedian from years ago talking about our insufferable inconsistencies in relation to the creation of basic shelter. It went something like this: In ancient times people were too cold or hot, miserable and tired of being rained on so they moved into caves. This was fine for a time but caves were dirty, Smokey from camp fires and infested with bugs or animals so humanity replicated the experience of a cave with artificial walled structures. Still it was too dark so we made windows. The windows let in bugs, rain and weather once again so we made shutters. The shutter design turned into blinds because sometimes we wanted to look out or let light in yet sometimes wanted to close off the outside world. Still not a perfect solution, so we developed glass. Humanity wasn't happy yet so our artificial caves needed glass windows which could be opened on the nice weather days to let fresh air in, closed for bad weather, shutters for occasional privacy and curtains on the inside for pure aesthetics. Most people despite thousands of years of structural engineering all this just keep their windows, shutters/blinds and curtains closed now and turn on a television to see what is going on outside...but the windows are still there!
I think the higher percentage of larger planets is mostly due to our ability to detect them, as our ability improves, I think we may start to detect more planetary systems like our own.
Seeing as how our primary means of detecting exoplanets is by measures changes in star emissions during planetary transits, its seems more likely to me that super earths, Hot jupiters and star hugging planets are not actually common but just easier to detect by us.
on the contrary, they may be very common. we’ve found many earth-like planets already by studying just a tiny field of view in the sky, and with only a tiny fraction of those stars actually having planetary systems that transit within our plane of view

Our Moon is the trope namer. Loosing copyright to genericity of a name is one thing. Saying Coke can't use the word "coke" because it is used as a generic word for "soft drink" is quite another. So it is relatively big in proportion? All the more justification for calling it "THE Moon". It is less confusing to define it as a limiting case, with anything a closer proportion of the size of its partner defined as a binary planet.
I constantly hear this: Life must be commonplace throughout the Milky Way galaxy. However, life is also the consequence is a very long chain of extremely unlikely coincidences.
we arent exactly doing a stellar job so far, once our oceans bend beyond breaking point, were knackered, ofc the ppl wrecking everything wont care as they will be long dead by the time it happens, and when it does happen we as a moronic species will only do something about it once its too late.
How can we be so certain in our solar system being very unique when we discovered only 4000 exoplanets around us keeping in mind that there are billions of stars and planets only in our galaxy and there are billions of galaxies out there?
Statistical analysis can give you a probability based on a sample. Say you examine 2000 random stars, you gather what information you can no matter how primitive your instruments. You compare them to each other and our own Sun. You find that other stars show similar qualities, which our own Sun doesn't. Out of the sample of 2000 stars our Sun is found to be unique, the chances are what ever other sample you take, you will find similar results. It doesn't mean there aren't other Sun like stars out there, it just means that the conditions which produce them are less common. Its pretty simple really.
I think if you calculate the odds of being in the right Galaxy, the right part of the Galaxy, with the right solar system, the right place in that solar system, the right planet, with the right large moon for axis stability, and other odds we are indeed the only planet with life
Hello! Tim from Alabama here. Just found your channel and subscribed. You are a master of your craft. You do the impossible. You make seemingly boring and overwhelming details of outer space approachable for me. Thank you so much!
You have to be cautious, because many of those things are just more visible and therfore we probably detected the first, and that's the reason they seem to be common.
The ones we can see are only a few thousand light-years away that means we are observing them a mere few thousand years ago which is less than a second on the universe time scale.
@EastCoastMC its why i am always never enthusiastic when scientists say they "may" have found an earth like planet, imagine some future people actually geared enough to excitedly visit one of these earth like planets only to discover during their travels that the planet/system ends up long dead by the time they get there and see its "current" state. Looking into history can help us learn things but its still a long past history we shouldnt take for granted on other worlds. Also if life does exist on other worlds then its normal to think we didnt all start at the same time in some parallel race, some species could be long dead or still puddles of goop in the ocean, we wouldnt even be here if a big old rock hadnt wiped out the dinosaurs and they were around for 1 heck of a long time, we arent even close to them in terms of longevity.
Considering that the solar activity of our own sun seems to match the orbital period of jupiter, the fact that most other stars having large and numerous planetary bodies close to them is probably an explanation of why our sun is so quiet. So you can actually group those two reasons together into one
If life naturally arises. If the cosmos is created by an intelligent designer, one would expect a stellar system to cater to the specific life it harbors.
Life is probably really, really rare. But with hundreds of trillions of stars out there, it's certainly happened lots of times. Even if there's just a 1 in billion chance of live arising around a given star, that's still 100,000 in the known universe.
@@ModMINI Or even more rare than one might think and we are alone. Keep in mind that the Sun is a second generation star and those type of stars are though to be more suitable for producing life sustaining planets. The universe is not old enough to have produced second generation stars in great numbers relative to other star types.
Technically or sun is going through the stellar equivalent of a mid life crisis in the sense that studies surveying main sequence stars have found that at 5 billion years of age G type stars seem to undergo a change in how magnetic dissipation of rotational energy occurs
Well done Anton. A brilliant talk. At the point at which you said 'our solar system is pretty rare' : I think you answered the Fermi Paradox. It would be interesting to read what other viewers think.
Excellent video. Almost all just observations with very little interpretations. Bravo!! All these unexplained fortuitous coincidences in our solar system _almost_ sound supernaturally miraculous like the big bang, or life coming accidentally from non-life, or consciousness coming from nowhere, or ... -- but we know better than that.
Left of the Cassiopaia "W", adding another zig to the zig zag of this constallation and being the brightest Star (0,5 mag) in this constallation. Ad Astra! 🚀
There is a simple explanation for all this. We are only just developing the ability to find other planets... and of course, the bigger they are and closer they are to their stars, then the occulations are easier to see. There will be billions of star systems very similar to our own, but finding small rocky planets far out from their stars... or even Jupiter and Saturns very far out, is extremely difficult or near impossible at this time.
A few of these points are likely due to systematic bias in our current observation methods. E.g. Hot Jupiters are especially easy to detect using the 'wobbling' of their host stars. Likewise, planets close to the star are also much easier to detect than ones farther from the star, due to the same limitations of 'wobbling' detection.
Regardless of the definition, the moon is an amazing gift to our species. If the Artemis missions are successful in building a permanent settlement on the moon in a few generations we will be harvesting resources from it on a scale that is impossible on Earth. With the resources of the moon incredible things can be built in orbit, including ships that may one day take us across the solar system and beyond. Without such an amazing moon it might be impossible to colonize other planets.
@Anton: I heard somewhere that we detect similar exoplanets because the methods we are using only show those kinds of planets. Maybe there are alot more systems like ours, but we just dont use the correct method to detect them?
You need to verify this information with the institutions actually doing the detection. Not some speculation by some people wanting to avoid the possibility that our solar system was deliberately made this way
Yeah its easier to detect bigger planets and planets that are close to their sun because we detect them by looking a regular dips in light intensity from that sun (aka planet passes in front of it). You need at least 3 passes to see a pattern. So if orbit is 3 years it takes us 9 years to detect it...
In other terms, (I believe) it's hard to detect a solar system similar to us, thus the perception biais we are different. But from what we detect today Anton seems to be right.
I always have a problem with this kind of comparison. Do we really KNOW that our system is weird or do we just not know enough about other system to even make that comparison? I strongly suspect the latter because our observational skills of other systems are not that good and depend on too many coincidences of planar orientation.
We've observed litterally thousands of systems very well. You are saying "Are scientists actually smart, or secretly just dumb as shit and lying to us, and I'm really the genius?" ... sorry mate, it's always smart to go with the assumption all the scientists in the world who devote their life to a subject understand it better.
I think the sample set of data AND the quality of the data dictates we can make the suggestion we are a bit of an anomaly BUT that we are utterly prepared to revise that opinion. We’ve looked, from vast distance, at an infinitesimal percentage of our one galaxy. Making a firm statement about it could be equivalent to defining the entirety of animal life on earth (for the entire history of earth) by looking at a family of beavers.
@@ThrottleKitty Yes, but the problem is methodology. How most exoplanets are discovered? They look at periodical dips in a star's luminosity. That means planets which are going to be detected are relatively large and have a very short period around the star. How possibly would you detect a planet like, say, Jupiter which has a period of 100 years? How about planets that don't even orbit their star in a way it'd get between said star and us? The answer is: you don't. The current methodology favours big planets with short periods and thus they make up for majority of planets we discovered.
@@LecherousLizard That's not really true. We've discovered a great deal of earth like, and earth sized planets. We have seen a relatively evens slice of the solar systems we can see.
Thanks Anton awesome video. These facts are probably an enormous reason why life is so hard to find. So many variables and obstacles preventing life to prosper elsewhere. This video and this information should be in school textbooks and television to educate everyone
Well we have 8 planets, 9 if you're Considering Pluto; which is a lot. A moon which perfectly eclipses the Sun in our sky. Plus we got a habitable planet with humans in it. 4 rocky planets and 4 gas giants; no super Earths and no hot Jupiters. Now tell me what are the odds you'll find a star system similar to us?
We don't know the odds. We're very far from knowing the true distribution of exoplanet types and system layouts. We're still gathering the low-hanging fruit.
@Kalsifer FN Pretty common if you ask me, Considering how uncommon gas giants are to terrestrial planets. Plus Trappist is a red dwarf star and they are EVERYWHERE in our galaxy.
The reason why other solar systems are compact unlike ours is because how we observe them. Let me explain, we detect planets outside our solar system by watching them transit their parent star. The planets that are near the star transit more often than the ones that are far away. So nearer planets may take more or less than one earth year, planets that are farther away may take tens or hundreds of years to finish an orbit. So if we're observing a star for like 5 or 10 years, we may only find the inner planets. But if we observe them for like 50 or 100 years, we may also find the outer planets. In conclusion, the reason we don't commonly see far away planets from their parent star is because we haven't observed them for long enough.
It wasn't that long ago the attitude was "if we're the only ones, it's an awful waste of space". Now it's becoming clear that our distance from the sun, type of sun, our "moon", the gas giants being huge vacuum cleaners for comets and asteroids...just isn't appearing to be very common based on the sampling done so far. I hope that there are billions of "other Earths" with all the same conditions but I suspect I'm not going to see it in my lifetime if they ever find any. And, of course there's the distance issue. We may find solar systems with exactly the same condition but unless we figure out how to travel at faster than light speed, it'll just be an interesting discovery that we can never explore. I'm grateful that all these strange situations that allowed for us to live and thrive happened.
The moment you realize how many solar systems there are in any given galaxy and how many galaxies there are, our solar system is perfectly understandable. Yes, there are all these coincidences but it's not weird if you throw the dice millions of trillions of times to result in something weird happening.
For stars/suns, are we able to determine the rate of nuclear fusion, for example from hydrogen to helium or from helium to carbon or from carbon to oxygen, for the various types of stars and see a correlation there? Or see a correlation to their sustained equilibrium? Or a correlation to their life spans?
I have watched a couple of your videos and I really enjoyed them. I like the way you describe things in a simple and articulate way. So I have decided to subscribe!! Looking forward to more videos.
Selection bias? It’s very different from everything else *we can see*. We don’t know if it’s very different from the vast majority of exoplanets we haven’t seen yet.
Our detection methods are biased towards larger planets and planets closer to their stars. No wonder we've found a lot of hot Jupiters and super earths.
yep we are limited in our current detection methods as the 'transit' method requires us to be looking at the Plain of the target Star system and the 'Wobble' Method the larger the planet and the faster is orbits make them easier to detect. Additionally the greater the distance to the Target Star System reduces the available resolution. Current Models only have Data for star systems relatively close to ourselves. Overall the Sample Size while in the thousands is only a small fraction of the Billions of Stars to look at.
Yes. We're just barely starting to be able to search for exomoons, so we don't know how rare Earth's moon is. Our selection biases favor finding large planets close to stars. So we've found lots of hot Jupiters and super-Earths. That's valuable knowledge: a few decades ago no one thought hot Jupiters were even possible. But it's too early, and the selection biases are too large, to claim we know that Earth or the Solar System are "rare".
Smaller earthlike planets that are about the size of earth are a lot harder to detect. The starwobbke they cause is to small. And if it passes in front of the star the absorbsion to to insignificant to differentiate from random fluctuations. Any more reasons for is to not find them?
@@IPlayWithFire135 Exactly, how long did it take us to find Mercury? and we're not very far away from that at all. I doubt that even the next generation of space telescopes would be able to find a planetary body like that orbiting another star.
Our Sun smokes weed, won't go out and get a job and just sits in his room, being mellow and sleeping most of the time. Stuff is growing all over his room because he never cleans it up. That's why we're here!
It may be that there are a few intelligent civilisations in the galaxy which will never intersect in time or space. A good signal may be from a civilisation which no longer exists.
@Call Me Ishmael They point out that our location 26,000 LY from the center is a huge factor as planets closer in have too much radiation from the surrounding stars. Their biggest point was with a billion species having lived on Earth, only one has ever been able to send a message out into space, so with planets having life, it doesn't mean it is advanced. Their book was very interesting, and I would like to see an update as well.
@@coweatsman "A good signal may be from a civilisation which no longer exists" - except once a civilization becomes type II (or even slightly less advanced) it's essentially eternal and indestructible...once they're able to colonize other systems, there's no way for them to go extinct any more (eg. say if Earth was somehow made inhabitable 10,000 years from now from say a super volcanic eruption, it's not the end because humanity has already colonized a bunch of other planets).
yes, Rare Earth is a great fascinating book! I've been thinking however that if humans are the only intelligent species in our galaxy, it is quite possible that we are the only intelligent species in the universe. Here is my reasoning, let me know what you think: If there really were an average of one per galaxy, it would be unlikely that each galaxy would actually have exactly one. It would be more likely for there to be a normal distribution where the galaxies most favorable to life would have very large numbers of intelligent species and other galaxies that were less favorable having none. Yet if such a distribution exists it would be much more likely that we would find ourselves in a galaxy that had lots of such species in it and unlikely that we would find ourselves in one that only had one. Therefore, if we are in a galaxy that only has one, that suggests that the average number may actually be far lower?

Denis YT it’s a trap, it is lulling us into a false sense of a security. When we all get comfortable with it, it’s just going to leave us. Like my ex-girlfriend.
@@coweatsman An interesting hypothesis but there would have to be some explanation for why Mercury's gas giant atmosphere is blown away but they seem to exist in large numbers in other solar systems, even in much closer orbits and even ones that have stars with much more active coronal mass ejections (and lots of solar wind). Maybe that's what happened, but we have to science to know for sure.
Very unlikely. Mercury is too far away from the Sun to have that kind of effect. Usually, hot Jupiters are around 3-4 stellar diameters away from their parent star. :P Mercury has a semi-major axis of approx. 0.34 astronomical units. Hot Jupiters have a semi-major axis of around 5,550,000 kilometers to around 9,950,000 kilometers. :P
Hi Anton, congrats fot your channel it's amazing! Your audio levels seem to be very low and I can barely hear you on max volume. Maybe its just my phone maybe its your post production, I hope this helps towards making your channel even better. Great voice and excellent narration skills. Thank you.
At 1:54 I hear that most discovered planetary systems have planets closer to their star, and heavier, not understood why. The explanation I find logical: Exoplanets are discovered by their dimming of their star during transit. Planets close to their star and large planets have a higher chance to be discovered by their dimming.
PS other differences, like presence of a brown dwarf, irregularity of trajectories seem to me more hazardous for development of life, just like an unmild sun. We would not exist without our solar system being relatively mild for life. Like Anton contradicts "unexplainable" near the end.
Anton for you a must watch is Professor Brian Cox latest release, May this year, telling the extraordinary life story of the solar system. For four and a half billion years each of the planets has been on an incredible journey, filled with astonishing spectacle and great drama. Using the data from the very latest explorations of the solar system combined with ground breaking CGI he reveals the unimaginable beauty and grandeur of eight planets. This answers a lot of questions you have raised ....keep up the good work Anton.
Anto, did you not read the paper from a couple of years ago where measurements suggested they had found our Sun's 5 siblings as they shared our Suns spectrographic measurements/observations. Indicating the same molecular cloud produced all of us 6
Hey Anton, love the channel! You have so many cool tools, please do a video on what you recommend! You probably have enough for a whole series of videos.
I don't pretend to know the math involved but I wonder if since the sun spins slowly, that means the accretion disc also spun slowly? Maybe that's why the planets are much further out in their orbits than other solar systems.
Good video, and I understand what your saying, BUT... You can't really say it's different than anything else out there, when we've only observed an infinitesimal portion of what's out there.
I always knew our backyard seemed slightly different to the neighbors, everything seems slightly to perfect. This is what makes me believe there is a creator, whatever or whoever that maybe. The size and distance of our moon, the rotation of our star, Jupiter taking our blows, I cannot deny that a God is a possibility.

@@lunafoxfire ... That's closer to the philosophical truth than desired... The dual slit experiment throws reality for a loop. The universe made humans so it could observe itself....
Anton, I want to clarify that it is not unusual for the sun to be not very active. Most solar type stars of 5 billion years are very slow rotators. Solar type stars that are very active have strong magnetic feedback from stellar winds that slow the star's rotation down. Check out the stellar rotation x-ray activity relationship by N J Wright 2011. It should be available on the ads archive. Rotation is tied to stellar activity. Praespe m37 pleiades and upper Sco stars are all are less than 1 billion years old and so most of their solar-type stars are still very active. Cheers.
Woah it's almost as if God put everything together so we can survive. All jokes aside this was a cool video, and I'll pray for all the folks here. God bless
@@anoj06 I don't.need to plead for God because the evidence is all around us. Life cannot come from no life, order can't arise from chaos, information cannot rise without intelligence; we can speculate a stupid movie idea like a matrix, which needs intelligence from aliens, but must reject God because now we are dealing with supernatural power, which must be mythology. But science fiction is fine.
Pretty sure its been explained why we dont have a hot jupiter. As jupiter migrated inward, saturn attracted it back out. And that's why there a ring of ice and rock between mars and jupiter.
Isn’t it great our sun is a calm quiet weirdo. Not like the rest of the universe being dangerous and aggressive. “Hail the sunshine, hail the sunshine”
I can see the Religious getting over excited about this video*rolls eyes*, but maybe it gives more weight to the special Earth theory that addresses the Fermi paradox .
We have only surveyed a very small portion of our own fraction of the galaxy and with really rudimentary systems, that can only detect outlier objects. When there are 100's of billions of stars to look at (in our galaxy) and only a few thousand have been studied, we shouldn't be making assumptions. It's like landing in the Arctic and claiming the world is covered only in ice.

When you consider the Fermi Paradox it does seem like our solar system is far from the typical set up,numerous things conspire to bring about a relatively safe environment for life to evolve,considering we aren't facing many life destroying incidents regularly,at least in comparison to other system set ups.
For example Jupiter and Luna help keep asteroids in check and our Star is mild when it comes to CMEs.

Hello! Tim from Alabama here. Just found your channel and subscribed. You are a master of your craft. You do the impossible. You make seemingly boring and overwhelming details of outer space approachable for me. Thank you so much!
You have to be cautious, because many of those things are just more visible and therfore we probably detected the first, and that's the reason they seem to be common.
We are observing solar systems how they look in the past, right? Maybe today they have a different setup.
The ones we can see are only a few thousand light-years away that means we are observing them a mere few thousand years ago which is less than a second on the universe time scale.
You mean star systems? Not solar systems.
Our local star is called Sol so this is the Solar System.
There aren't other Solar Systems...
@EastCoastMC its why i am always never enthusiastic when scientists say they "may" have found an earth like planet, imagine some future people actually geared enough to excitedly visit one of these earth like planets only to discover during their travels that the planet/system ends up long dead by the time they get there and see its "current" state.
Looking into history can help us learn things but its still a long past history we shouldnt take for granted on other worlds. Also if life does exist on other worlds then its normal to think we didnt all start at the same time in some parallel race, some species could be long dead or still puddles of goop in the ocean, we wouldnt even be here if a big old rock hadnt wiped out the dinosaurs and they were around for 1 heck of a long time, we arent even close to them in terms of longevity.
Considering that the solar activity of our own sun seems to match the orbital period of jupiter, the fact that most other stars having large and numerous planetary bodies close to them is probably an explanation of why our sun is so quiet. So you can actually group those two reasons together into one
Correlation is not causation. So no you can't assume.
Hmm, so Jupiter is Sun's binary partner?
@Jackalovski: Do you have a source for that? I'd love to learn more!
Anton makes wonderful persons with his greeting. Conclusion: Alien
More reasons why complex life is rarer than some people think....
If life naturally arises. If the cosmos is created by an intelligent designer, one would expect a stellar system to cater to the specific life it harbors.
Life is probably really, really rare. But with hundreds of trillions of stars out there, it's certainly happened lots of times. Even if there's just a 1 in billion chance of live arising around a given star, that's still 100,000 in the known universe.
@@ModMINI Or even more rare than one might think and we are alone. Keep in mind that the Sun is a second generation star and those type of stars are though to be more suitable for producing life sustaining planets. The universe is not old enough to have produced second generation stars in great numbers relative to other star types.
@@voltrondefenderoftheuniver6222 I had the same thought but most here myself included don't believe in a universal God.
@@jamesdunn9714 Ok, instead of 100,000, maybe 20,000. There are PLENTY of second generation stars out there. Elliptical galaxies are full of them.
“Hello wonderful person”
I love it.
Re Super Earths / Hot Jupiters: this is because our search is biased towards big planets. That was easy.
Wow! That's a really good point.
Wow! That's a really good point.
I was already familiar with this topic but really enjoy your explanation and presentation. Love all your videos, new subscriber🙋
Love ya, Anton! Thank you for another great learning experience!
Our universe is like space engine used as background for videos by some entity on higher dimensional equivalent of UA-cam.
And we are the bug
Sun's just enjoying that bachelor life. We're growing on all the unwashed dishes in the sink...
:D
Technically or sun is going through the stellar equivalent of a mid life crisis in the sense that studies surveying main sequence stars have found that at 5 billion years of age G type stars seem to undergo a change in how magnetic dissipation of rotational energy occurs
ROFL!
Haha thats awesome
Hope he doesn't get a clean freak gf
I really appreciate the hard work you and the team put to bring such quality videos at this frequency. Amazing! Thank you!!
Well done Anton. A brilliant talk. At the point at which you said 'our solar system is pretty rare' : I think you answered the Fermi Paradox. It would be interesting to read what other viewers think.
Excellent video. Almost all just observations with very little interpretations. Bravo!!
All these unexplained fortuitous coincidences in our solar system _almost_ sound supernaturally miraculous like the big bang, or life coming accidentally from non-life, or consciousness coming from nowhere, or ... -- but we know better than that.
Our solar system contains the biggest weirdo in the universe, therefore it is weird indeed. Me.
Hello
allow me to introduce myself
Greetings
@Celtic Revival / Adfywiad Celtaidd chi o ogledd cymru?
Uh, so you are the reason people stopped calling me weirdo. Thanks!
As seen from the nearest star to the sun Proxima Centauri, what constellation would the sun appear to be in and how bright would it appear?
Left of the Cassiopaia "W", adding another zig to the zig zag of this constallation and being the brightest Star (0,5 mag) in this constallation. Ad Astra! 🚀
crazily enough, the constellations would be almost identical on Proxima Centauri as the are here!
Great video. Easy to understand and the vids just add to it.
Hello Wonderful Anton! Thank you for showing me a bit of astronomy. Thanks!
There is a simple explanation for all this. We are only just developing the ability to find other planets... and of course, the bigger they are and closer they are to their stars, then the occulations are easier to see.
There will be billions of star systems very similar to our own, but finding small rocky planets far out from their stars... or even Jupiter and Saturns very far out, is extremely difficult or near impossible at this time.
A few of these points are likely due to systematic bias in our current observation methods. E.g. Hot Jupiters are especially easy to detect using the 'wobbling' of their host stars. Likewise, planets close to the star are also much easier to detect than ones farther from the star, due to the same limitations of 'wobbling' detection.
I hope this doesn't come across as diabolical, but I would LOVE to witness a planet plunging into it's parent star. That would be EPIC!
The moon got promoted!
Cheers moon! You are now a planet!
suck it Pluto (+Charon)
Gary Oldham *cries in Pluto*
if moon is a planet now... bring Pluto back!
Regardless of the definition, the moon is an amazing gift to our species. If the Artemis missions are successful in building a permanent settlement on the moon in a few generations we will be harvesting resources from it on a scale that is impossible on Earth. With the resources of the moon incredible things can be built in orbit, including ships that may one day take us across the solar system and beyond. Without such an amazing moon it might be impossible to colonize other planets.
@@MrWinotu Moon is much larger than Pluto-
@Anton: I heard somewhere that we detect similar exoplanets because the methods we are using only show those kinds of planets. Maybe there are alot more systems like ours, but we just dont use the correct method to detect them?
You need to verify this information with the institutions actually doing the detection. Not some speculation by some people wanting to avoid the possibility that our solar system was deliberately made this way
Im not sure if i get what you are saying. How can somebody avoid a possibilty? Either way, thats not what i was asking Anton.
Yeah its easier to detect bigger planets and planets that are close to their sun because we detect them by looking a regular dips in light intensity from that sun (aka planet passes in front of it). You need at least 3 passes to see a pattern. So if orbit is 3 years it takes us 9 years to detect it...
@@mouzurX so imagine now some planets that need over 100 years to circle their planet... we cannot see them (Jupiter or Saturn are like this).
In other terms, (I believe) it's hard to detect a solar system similar to us, thus the perception biais we are different. But from what we detect today Anton seems to be right.
I always have a problem with this kind of comparison. Do we really KNOW that our system is weird or do we just not know enough about other system to even make that comparison? I strongly suspect the latter because our observational skills of other systems are not that good and depend on too many coincidences of planar orientation.
We've observed litterally thousands of systems very well. You are saying "Are scientists actually smart, or secretly just dumb as shit and lying to us, and I'm really the genius?" ... sorry mate, it's always smart to go with the assumption all the scientists in the world who devote their life to a subject understand it better.
I think the sample set of data AND the quality of the data dictates we can make the suggestion we are a bit of an anomaly BUT that we are utterly prepared to revise that opinion.
We’ve looked, from vast distance, at an infinitesimal percentage of our one galaxy. Making a firm statement about it could be equivalent to defining the entirety of animal life on earth (for the entire history of earth) by looking at a family of beavers.
@@ThrottleKitty we may have checked thousands but theres a little more than several thousand samples to compare ourselves to.
@@ThrottleKitty Yes, but the problem is methodology.
How most exoplanets are discovered? They look at periodical dips in a star's luminosity.
That means planets which are going to be detected are relatively large and have a very short period around the star.
How possibly would you detect a planet like, say, Jupiter which has a period of 100 years?
How about planets that don't even orbit their star in a way it'd get between said star and us?
The answer is: you don't.
The current methodology favours big planets with short periods and thus they make up for majority of planets we discovered.
@@LecherousLizard That's not really true. We've discovered a great deal of earth like, and earth sized planets. We have seen a relatively evens slice of the solar systems we can see.
Thanks Anton awesome video. These facts are probably an enormous reason why life is so hard to find. So many variables and obstacles preventing life to prosper elsewhere. This video and this information should be in school textbooks and television to educate everyone
Hello wonderful person, I like the way you explain the facts to us. KEEP LOOKING UP...
Well we have 8 planets, 9 if you're Considering Pluto; which is a lot. A moon which perfectly eclipses the Sun in our sky. Plus we got a habitable planet with humans in it. 4 rocky planets and 4 gas giants; no super Earths and no hot Jupiters. Now tell me what are the odds you'll find a star system similar to us?
if universe is that big as they say you have 100% there are similiar star systems or even the same
We don't know the odds. We're very far from knowing the true distribution of exoplanet types and system layouts. We're still gathering the low-hanging fruit.
@Kalsifer FN Pretty common if you ask me, Considering how uncommon gas giants are to terrestrial planets. Plus Trappist is a red dwarf star and they are EVERYWHERE in our galaxy.
The reason why other solar systems are compact unlike ours is because how we observe them. Let me explain, we detect planets outside our solar system by watching them transit their parent star. The planets that are near the star transit more often than the ones that are far away. So nearer planets may take more or less than one earth year, planets that are farther away may take tens or hundreds of years to finish an orbit. So if we're observing a star for like 5 or 10 years, we may only find the inner planets. But if we observe them for like 50 or 100 years, we may also find the outer planets. In conclusion, the reason we don't commonly see far away planets from their parent star is because we haven't observed them for long enough.
Thank you Anton Petrov for an interesting video! I really enjoy your channel 😊
Our solar system seems to be very weird indeed, but lets not forget that our universe is probably 10x bigger than the observable universe.
More like 1000x or even infinite
Our Solar System gets bullied by others... Cuz we are different.
It wasn't that long ago the attitude was "if we're the only ones, it's an awful waste of space". Now it's becoming clear that our distance from the sun, type of sun, our "moon", the gas giants being huge vacuum cleaners for comets and asteroids...just isn't appearing to be very common based on the sampling done so far. I hope that there are billions of "other Earths" with all the same conditions but I suspect I'm not going to see it in my lifetime if they ever find any. And, of course there's the distance issue. We may find solar systems with exactly the same condition but unless we figure out how to travel at faster than light speed, it'll just be an interesting discovery that we can never explore. I'm grateful that all these strange situations that allowed for us to live and thrive happened.
Thanks teach! I wish I had a teacher like you when I was younger but I'm get something even better in my late 30's.
Wonder if our solar system is artifical a specially made ideal system
The moment you realize how many solar systems there are in any given galaxy and how many galaxies there are, our solar system is perfectly understandable. Yes, there are all these coincidences but it's not weird if you throw the dice millions of trillions of times to result in something weird happening.
For stars/suns, are we able to determine the rate of nuclear fusion, for example from hydrogen to helium or from helium to carbon or from carbon to oxygen, for the various types of stars and see a correlation there? Or see a correlation to their sustained equilibrium? Or a correlation to their life spans?
The bigger a star is when it forms, the shorter lived it is. Barring interactions with companions. Lookup main sequence, Hertzsprung-Russell diagram.
It truly is amazing how the sun, Earth and moon are all so stable and all this to produce life, makes you wonder about what else could be out there
I have watched a couple of your videos and I really enjoyed them. I like the way you describe things in a simple and articulate way. So I have decided to subscribe!! Looking forward to more videos.
Because were trying to raid a military base in Nevada and don’t care if we die
Selection bias? It’s very different from everything else *we can see*.
We don’t know if it’s very different from the vast majority of exoplanets we haven’t seen yet.
Our detection methods are biased towards larger planets and planets closer to their stars. No wonder we've found a lot of hot Jupiters and super earths.
yep we are limited in our current detection methods as the 'transit' method requires us to be looking at the Plain of the target Star system and the 'Wobble' Method the larger the planet and the faster is orbits make them easier to detect. Additionally the greater the distance to the Target Star System reduces the available resolution. Current Models only have Data for star systems relatively close to ourselves. Overall the Sample Size while in the thousands is only a small fraction of the Billions of Stars to look at.
Yes. We're just barely starting to be able to search for exomoons, so we don't know how rare Earth's moon is. Our selection biases favor finding large planets close to stars. So we've found lots of hot Jupiters and super-Earths.
That's valuable knowledge: a few decades ago no one thought hot Jupiters were even possible. But it's too early, and the selection biases are too large, to claim we know that Earth or the Solar System are "rare".
Smaller earthlike planets that are about the size of earth are a lot harder to detect. The starwobbke they cause is to small. And if it passes in front of the star the absorbsion to to insignificant to differentiate from random fluctuations. Any more reasons for is to not find them?
@@IPlayWithFire135 Exactly, how long did it take us to find Mercury? and we're not very far away from that at all. I doubt that even the next generation of space telescopes would be able to find a planetary body like that orbiting another star.
Excellent video. Extremely interesting and important video with implications relating to the scarcity of extraterrestrial intelligent life.
It's cool that this sandbox helps to make a quality video without having to use stock photos and the likes.
Our Sun smokes weed, won't go out and get a job and just sits in his room, being mellow and sleeping most of the time. Stuff is growing all over his room because he never cleans it up. That's why we're here!
Perhaps this means intelligent space faring civilizations are extremely rare, perhaps a handful per galaxy.
It may be that there are a few intelligent civilisations in the galaxy which will never intersect in time or space. A good signal may be from a civilisation which no longer exists.
@Call Me Ishmael They point out that our location 26,000 LY from the center is a huge factor as planets closer in have too much radiation from the surrounding stars. Their biggest point was with a billion species having lived on Earth, only one has ever been able to send a message out into space, so with planets having life, it doesn't mean it is advanced. Their book was very interesting, and I would like to see an update as well.
@@coweatsman "A good signal may be from a civilisation which no longer exists" - except once a civilization becomes type II (or even slightly less advanced) it's essentially eternal and indestructible...once they're able to colonize other systems, there's no way for them to go extinct any more (eg. say if Earth was somehow made inhabitable 10,000 years from now from say a super volcanic eruption, it's not the end because humanity has already colonized a bunch of other planets).
We can't even get people to mars. I think calling ourselves 'space faring' is being quite generous.
yes, Rare Earth is a great fascinating book!
I've been thinking however that if humans are the only intelligent species in our galaxy, it is quite possible that we are the only intelligent species in the universe. Here is my reasoning, let me know what you think: If there really were an average of one per galaxy, it would be unlikely that each galaxy would actually have exactly one. It would be more likely for there to be a normal distribution where the galaxies most favorable to life would have very large numbers of intelligent species and other galaxies that were less favorable having none. Yet if such a distribution exists it would be much more likely that we would find ourselves in a galaxy that had lots of such species in it and unlikely that we would find ourselves in one that only had one. Therefore, if we are in a galaxy that only has one, that suggests that the average number may actually be far lower?
Our sun is kind of a weirdo of the galaxy... make a t-shirt with that

What if Mercury used to be a hot Jupiter that had all of its atmosphere blown away?
Mercury does have an unusually dense large core for its size so that is possible.
@@coweatsman An interesting hypothesis but there would have to be some explanation for why Mercury's gas giant atmosphere is blown away but they seem to exist in large numbers in other solar systems, even in much closer orbits and even ones that have stars with much more active coronal mass ejections (and lots of solar wind). Maybe that's what happened, but we have to science to know for sure.
wow I never heard that one before. An interesting thought for sure.
what if earth used to be a hot jupiter and had nearly all its atmosphere blown away
Very unlikely. Mercury is too far away from the Sun to have that kind of effect.
Usually, hot Jupiters are around 3-4 stellar diameters away from their parent star. :P
Mercury has a semi-major axis of approx. 0.34 astronomical units.
Hot Jupiters have a semi-major axis of around 5,550,000 kilometers to around 9,950,000 kilometers. :P
Hi Anton, congrats fot your channel it's amazing! Your audio levels seem to be very low and I can barely hear you on max volume. Maybe its just my phone maybe its your post production, I hope this helps towards making your channel even better. Great voice and excellent narration skills. Thank you.
At 1:54 I hear that most discovered planetary systems have planets closer to their star, and heavier, not understood why.
The explanation I find logical: Exoplanets are discovered by their dimming of their star during transit. Planets close to their star and large planets have a higher chance to be discovered by their dimming.
PS other differences, like presence of a brown dwarf, irregularity of trajectories seem to me more hazardous for development of life, just like an unmild sun. We would not exist without our solar system being relatively mild for life. Like Anton contradicts "unexplainable" near the end.
Gee whiz sure are some nasty comments here Must be the heat .
Good report keep it up don't let stupid people get under your skin.
So nice👍🏻
Anton for you a must watch is Professor Brian Cox latest release, May this year, telling the extraordinary life story of the solar system. For four and a half billion years each of the planets has been on an incredible journey, filled with astonishing spectacle and great drama. Using the data from the very latest explorations of the solar system combined with ground breaking CGI he reveals the unimaginable beauty and grandeur of eight planets. This answers a lot of questions you have raised ....keep up the good work Anton.
Anto, did you not read the paper from a couple of years ago where measurements suggested they had found our Sun's 5 siblings as they shared our Suns spectrographic measurements/observations. Indicating the same molecular cloud produced all of us 6
"Scientist admits current techniques aren't very good at spotting Earth like planets in Earth like orbits".
Except that is exactly what we are looking for and should be the very BEST at.
Even if we're one in a million, there is plenty of systems like ours.
So where are they?
Hey Anton, love the channel! You have so many cool tools, please do a video on what you recommend! You probably have enough for a whole series of videos.
I don't pretend to know the math involved but I wonder if since the sun spins slowly, that means the accretion disc also spun slowly? Maybe that's why the planets are much further out in their orbits than other solar systems.
Good video, and I understand what your saying, BUT... You can't really say it's different than anything else out there, when we've only observed an infinitesimal portion of what's out there.
So our sun is rare, our moon is unique and our solar system doesn't match anything else we have found... I'll take the red pill!
really enjoying the content Anton

Right up there with Dr. Becky. Thanks!
I always knew our backyard seemed slightly different to the neighbors, everything seems slightly to perfect.

@@paradisebreeze1705 Perhaps not completely alone, but for the time being, functionally speaking, yes.
@@debbie74dj we "lucked up" because life was guarenteed to be made on a planet like earth. The conditions are perfect for life of all shapes and sizes, so it would be a big captain obvious that an alien would think "ye some life will spawn here."

So far. I expect we'll find solar systems much like ours all over the place eventually. We only have exact details of a miniscule part of our galaxy.
Anton, I want to clarify that it is not unusual for the sun to be not very active. Most solar type stars of 5 billion years are very slow rotators. Solar type stars that are very active have strong magnetic feedback from stellar winds that slow the star's rotation down. Check out the stellar rotation x-ray activity relationship by N J Wright 2011. It should be available on the ads archive. Rotation is tied to stellar activity. Praespe m37 pleiades and upper Sco stars are all are less than 1 billion years old and so most of their solar-type stars are still very active.
Cheers.

We have only surveyed a very small portion of our own fraction of the galaxy and with really rudimentary systems, that can only detect outlier objects. When there are 100's of billions of stars to look at (in our galaxy) and only a few thousand have been studied, we shouldn't be making assumptions. It's like landing in the Arctic and claiming the world is covered only in ice.
