Thank you for being honest an unbiased, for not following an agenda and admitting when you don't know. In my opinion the more we really look into the universe and science without biased and with an open mind the more it is apparent that there is a creator.
Interesting though is the presentation that says 1 out of 200 stars is like our Sun (500 million conservatively in the Milky Way alone), but yet aren't common. That would seem a bias towards rarity, when the data conservatively suggests "not so rare".
@@StefenTower my quick math said 1 out of 300. Still you have a point. I think the presentation is just not detailed enough. What would be important to elucidate is the bit about 'stars like our sun often have more severe solar flares'. Stars like our sun how? Just the same type? Same type and age? Same type and age and belonging to this 'lower third' of activity level? I think that would help.
The work that the team is producing here is really incredible. It's so uniquely creative and innovative. Many arguments have been made about what constitutes a definition of life over time. From self-replication to carbon-based chemistry, etc. Although one that has always struck me as the broadest catch-all conception is that on all levels-life seeks out and thrives in low entropy environments. Almost as if the raison d'etre of life is to forever fight entropy. Indeed, a low entropic star like our Sun fits this conception of where life might find a hospitable home quite perfectly. Though order can be seen in natural formations throughout the universe; it's difficult to conceive of discovering extrasolar life without a low entropic signature of some sort. In this vein, it seems that this conception is where we should really begin our search for extrasolar life: low entropic stellar and galactic environments. This idea, in particular, got me thinking-about Hoag's Object (PGC 54559) and the Terrascope concept. I can't recall ever seeing such an ordered structure in all of Astronomy. Indeed, some of the largest constructions ever created by our species throughout history have been observatories. Could it be that Hoag's Object is a massive galactic lens structure? With the outer ring forming a kind of aperture that can be manipulated? It's often conceived that the manipulation of matter would be a telltale sign of life, but what about the manipulation and structural management of empty space as well?
This is the best channel on TH-cam. Hands down. Interesting mix of history, scientific depth, incredible narrative, storytelling and excellent videography. Well done Cool Worlds. Bravo. 👏👏👏
Absolutely loved the setting used for filming! Greenery, chirping birds! Such a right decision, even if caused by the current situation - this puts at the center the very thing that the video talks about, the sun and all the life it creates here on Earth. Also, your voice is so comforting! Perfect for the calm discussion of science, especially study of such grand scales. It puts me in a trance-like state, but not like a sedative, just calms a mind immediately - to listen, to think and to remember what really matters.
Thanks! It’s always tricky with lighting and audio outside, especially as someone who’s trained in astronomy and not cinematography! But I personally really enjoy a change of scenery and getting some fresh air for filming.
What you have done (by yourself !), is what is known as ‘film magic,’ lol, & man, there are reams of ‘info,’ & ideas, written about it !!! &, you have such wonderful info, to impart ! 💜✨🔆🌎. [Early filmmakers, before advent of ‘sound,’ had to be ‘inventive,’ & some were great masters at it, ref. modern film ‘Hugo,’ about the early filmic wizard, Georges Melies, played by Ben Kingsley... for example, lol, film & astronomy, are 2 great loves of my own ! ]. I Love what you have given us here. Thank you, most sincerely.
Yes, I also like to see videos filmed outside. As I spend several hours of nearly every day either gardening or out walking, makes me feel right at home while listening to a subject that's interested me since a young child.
Thank you Cool Worlds team for yet another gem. Great topic. And by the way love the outdoor wooded setting for the video. A refreshing change from having to look at everyone's home office! Stay safe and keep the great work coming...

@@Ron4885 Marxism has created self destructive behavior. The sun, moon and earth will be here long after the enemies of humanity are stomped into ground.
As far as we can tell, for the vast majority of the history of life on Earth, it was single-celled organisms. Multi-cellular life might be extremely rare.
N Strat Yes! And back then, our cell phones were made of wood and we'd have to make our own 'clicking' sounds when we were pretending to text. Contact lenses were also made of wood back then and splinters made them difficult to wear so we had to sand them very carefully and, well-being opaque-they made riding the smaller and faster dinosaurs quite unsafe. (Sssso glad they invented insurance soon thereafter...) Working under unicellular bosses did nothing for our job satisfaction back then but you sure could pack the little bastards into the boardroom like nobody's business. It was a bad day when you stepped on a whole team of executives because your contact lenses were of a denser hardwood under your sucky benefits and your dino wiped out on the way home all because you were texting your frustration into a small piece of wood when you should have been watching the road. 'Good old days, my ass': we really do have it good nowadays…

@@MichaelMajeran true Poland and Germany have a very complicated history we've been invaded by them multiple times so a lot of poles were and are accustomed to the language places like Silesia still have German influence to this day
This is a wonderful & clear explanation as to how life on this planet, in this Universe has absolutely nothing to do with religion, and everything to do with the 'roll of the dice'.
One of the other ways in which it appears we may be "special" has been the discovery that we are in a void. A void being a region of space in which the density of galaxies is low, very low. Not only do we live in a void but our void is a super void meaning that it is a lot bigger than "normal" voids. And not just any super void, the largest super void in the observable universe. This presents the problem that our measurements of how fast the universe is expanding may have been thrown off by living in an unusual part of the universe.
If the universe is expanding and we can't travel back and forth even at light speed. . I assume. Early life had a choice. Go with the flow, or fight the tide. . But contextually since this is space, would it not be easier to just travel inward to the "center" since it is traveling towards you. . If u travel away it might be more difficult or easier. . The defining factor, the direction your galaxy travels and where the big bang emminated from. . The real question. Where do we stand from the center. . Is life emminating from a circular safe zone from the big bang? Or is it a time thing. . If life existed before us and is out there. Would we find more in the edge or towards the center?
His dedication and passion is admirable. I cannot believe this channel just has less than 500k subscribers. Guys, let's tell everyone to subscribe to his channel and support his research by not skipping ads.
Another fascinating 'special' piece that we've started to come to understand recently is the structure of our solar system. This may be a bias of them being easier to find, but we've found a LOT of solar systems where the 'inner system' (i.e. the Goldilocks zone) is filled with a couple massive gas giants, Jupiters or larger. No rocky worlds that might host liquid water and life there, at least not as independent planets. And even rocky, Earth-sized moons are likely uninhabitable, between the gas giants' radiation belts, the gravitational flux commonly seen in such moons in our system, and the extended periods of total solar eclipse as the moon moves into the shadow of the giant. Our system has no such 'inner giants', and instead seems to host a slew of 'outer giants', something we again haven't seen in many systems yet. It is theorized that these 'outer giants' acted as asteroid shields during the more chaotic periods of the early system, allowing life an earlier start on Earth than it may otherwise have enjoyed.
There is evidence that suggests that Jupiter was on an inward spiral towards the sun also but Saturn actually pulled Jupiter back to the outer solar system!
the only way anyone can dislike the videos on this channel are being someone who doesnt believe there's something beyond this world (no judging here... not right now at least..). It must be wonderful being instructed by professor Kipping..
Video is very interesting, I am glad to have valuable content like this on YT. Thank you for spotting and correcting Copernicus origin as he was born in Poland (Torun - there is university named after him) and died in Poland, and as a Polish astronomer he has contributed to the changes which are affecting our lives even today. Apart of Polish he spoken German, Italian, Latin and Greek. This made him open-minded. Great respect, I love the channel. 👍
Dear Mr Kipping, thanks for the presentation. Just like your other video on whether we are alone or not in the vastness of the universe, so too, in this one your presentation is superb and you manage to keep "neutral". I was expecting though to see towards which side you are leaning but no avail. I did come to the conclusion that the sun is rare, the earth is rare and we are unique and alone; based on your presentation. "The sun ripens a bunch of grapes as if it had nothing else in the universe to do (Galileo Galilei)" Thank you again.
If you can't see how special the whole arrangement of this huge machine, you wouldn't believe it actually exists. Everything is perfect for life. No mistakes. Also the sun burning for billions of years, it should have changed or run low on fuel, but what we will learn is that the whole universe is a huge machine, and energy goes wireless to where there is need and where it is abundant. The possibility of all these factors going on with out a glitch, the moon being at the right place, the sun being at the right place and continuing to work as it has for billions of years. We don't see the picture yet because we believe that it is good chances, nothing is as long lasting to be chance.
I am not even close to anything a scientist but my god he sure explains it to the core. Plus it's asmr to my mind. I think more when I hear him. Good job doctor. Keep up the good work. Enlighten us commons more about things we don't know.
it is fascinating how things that are vital for us can be dangerous and deadly at the same time. Instead of seeing the forces of nature entirely negatively, we should remember that they are part of a larger system that guarantees our lives.
Also please note that depending on the time in history Poland has been both German and or Russian. My family history is "germanic" but the ancient family castle is located in what is now Poland.
Thank you, Dr. Kipping, for another excellent presentation! I have believed that “Rare Earth” is probably correct . It seems that “Rare Sun”, as far as we now know, applies as well….
I just love it. Your videos take me on a journey of wonder and discovery. They ponder important questions and are delivered in a way that makes it accessible to everyone. Well done cool worlds.
Why in the galaxy would any part of the presentation make one sad, I wonder? What specifically, andrew, has made you feel sad? Is it the part where he said Copernicus was German? That was unsportsmanlike.
Sad in the sense that so many unlikely events had to transpire to form our sun and this solar system and our planet that it is more than likely that we are alone in this galaxy. At least in the sense that we are the only macroscopic technological species
maybe someone was up set over finding out we not special! or brokenhearted over finding out we are mediocre! it is hard for some to trade in hubris for humility.
I'm sure others have already commented this but Copernicus was Polish! Haha His non-latinized name was Mikolaj Kopernik. If I am not mistaken, he played a pivotal role in pushing heliocentrism into an accepted principal of our solar system, much to the chagrine of the Catholic Church.
A correction. It doesn't take 8 minutes for a photon to go from the sun's core to the earth. It can take up to a 100000 years to go from the core to the surface. It then takes 8 minutes from the surface to the earth.
However im also wondering why NASA don't review or research deeper on the nearer Yellow dwarf star named Tau Ceti which is only 12 lightyears away on our solar system.. Its mass is 79% of sun and Luminousity of 65-70% of our Sun,it has three Rocket world (4 Planets confirmed)and two of those Rocky world were potentially Habitable, accordingly it was 7Billion years old(3Billion years older than our Sun)yet it still Cooler and dimmer than our sun cause its it has slightly less mass than our sun means it will live stable for another 2Billion years.. In my Opinion why not NASA put their heads on to Study Tau Ceti since its similar to our sun and has also a massive solar system similar to our own
I love your shows and think you're a brilliant scientist. I have also always thought maybe it's our sun that's different and why there is life here. Not the earth necessarily.
Another interesting, informative, and excellent video. Even reducing the percentage to 0.5%, as stated near the conclusion of the video, given the astronomical numbers, we are still dealing with huge numbers. Another consideration and concern is the effects of even moderate increase in solar activity on, e.g., the atmosphere, animal and human health, the electrical grid, communications satellites, and electrical and electronic components. Such a solar event similar or greater than the Carrington Event would likely cause cascading failures and lead to a plurality of major worldwide disasters.
yes but only because we did not build for Carrington levels, but if too powerful it could/would blow atmosphere right off or microwave (ish) the planet periodically (both not good for life).
@@fredricknietzsche7316 carrington level flares are common, the fact that more and more stars are found to have a cycle of recurring x-flare or micro nova is slightly more disturbing.. if you are interested in such events which our ancestors might have witnessed thousands of years ago, i'd recommend this paper by Anthony L. Peratt: Characteristics for the Occurrence of a High-Current, Z-Pinch Aurora as Recorded in Antiquity. this paper is one that makes you think and ponder, you are warned..
I ask this humbly, as I have no science background, but from my uneducated standpoint, is it possible that the 'Rare Earth' and 'Rare Sun' hypotheses exist co-dependently? I mean to ask.. is it possible the Mars sized object that crashed into Proto-Earth which purportedly created the Earth and Moon as we now know them to be also coincidentally occurred within the reach of a 'Rare Sun'? Can a 'Rare Sun" give rise to life simply by being a 'Rare Sun'?
How far out can we reasonably extrapolate this effect? Rare Sun, Rare Earth, Rare Solar system, Rare Quiet Spot on an Outer Arm of a Rare Galaxy in a relatively quiet parcel of space......? Could crunching these numbers give us a better idea of the possibility and possible locations of intelligent life?
I apologize for my naivete in these matters. I cannot speak intelligently about physics or mathematics or the like, though I wish I could. Your presentations of the workings of the Cosmos are captivating, to say the least. What intrigues me are the pattern repetitions in nature that seem to apply equally in the macro and micro worlds. Given the equilibrium Einstein's theory of relativity gifts to everything outside of a singularity, is it too far a stretch to use our galactic pattern, in its entirety, as the benchmark for where to look for life?
I don't have a science background, but after watching this, it does make me wonder if that is the solution to the fermi paradox. That having a rare earth that orbits a rare sun is so rare, that it only happens once every few galaxies or so.
@@SnootchieBootchies27 Thank you for the like. 'Rare' is a term used so frequently when referring to life on this planet and our planet itself. I think the math is going in the wrong direction. If you add up the rarity factors it would show how impossible it is that we are here. And yet here we are. Phx Bias
@@PhoenixBiasAmberBiasMusic Bad news: "The ability to retain an atmosphere is related to the magnetic field, which is also driven by internal heating. Prof. Primack noted that the heavy elements crucial to radiogenic heating are created during mergers of neutron stars, which are extremely rare events. The abundance of uranium and thorium appear to be key factors, possibly even another dimension for defining a Goldilocks planet."

@@StefenTower my quick math said 1 out of 300. Still you have a point. I think the presentation is just not detailed enough. What would be important to elucidate is the bit about 'stars like our sun often have more severe solar flares'. Stars like our sun how? Just the same type? Same type and age? Same type and age and belonging to this 'lower third' of activity level? I think that would help.
The work that the team is producing here is really incredible. It's so uniquely creative and innovative.
Many arguments have been made about what constitutes a definition of life over time. From self-replication to carbon-based chemistry, etc. Although one that has always struck me as the broadest catch-all conception is that on all levels-life seeks out and thrives in low entropy environments. Almost as if the raison d'etre of life is to forever fight entropy. Indeed, a low entropic star like our Sun fits this conception of where life might find a hospitable home quite perfectly.
Though order can be seen in natural formations throughout the universe; it's difficult to conceive of discovering extrasolar life without a low entropic signature of some sort. In this vein, it seems that this conception is where we should really begin our search for extrasolar life: low entropic stellar and galactic environments.
This idea, in particular, got me thinking-about Hoag's Object (PGC 54559) and the Terrascope concept. I can't recall ever seeing such an ordered structure in all of Astronomy. Indeed, some of the largest constructions ever created by our species throughout history have been observatories. Could it be that Hoag's Object is a massive galactic lens structure? With the outer ring forming a kind of aperture that can be manipulated? It's often conceived that the manipulation of matter would be a telltale sign of life, but what about the manipulation and structural management of empty space as well?
This is the best channel on TH-cam. Hands down. Interesting mix of history, scientific depth, incredible narrative, storytelling and excellent videography. Well done Cool Worlds. Bravo. 👏👏👏
Absolutely loved the setting used for filming! Greenery, chirping birds! Such a right decision, even if caused by the current situation - this puts at the center the very thing that the video talks about, the sun and all the life it creates here on Earth.
Also, your voice is so comforting! Perfect for the calm discussion of science, especially study of such grand scales. It puts me in a trance-like state, but not like a sedative, just calms a mind immediately - to listen, to think and to remember what really matters.
Thanks! It’s always tricky with lighting and audio outside, especially as someone who’s trained in astronomy and not cinematography! But I personally really enjoy a change of scenery and getting some fresh air for filming.
What you have done (by yourself !), is what is known as ‘film magic,’ lol, & man, there are reams of ‘info,’ & ideas, written about it !!! &, you have such wonderful info, to impart ! 💜✨🔆🌎. [Early filmmakers, before advent of ‘sound,’ had to be ‘inventive,’ & some were great masters at it, ref. modern film ‘Hugo,’ about the early filmic wizard, Georges Melies, played by Ben Kingsley... for example, lol, film & astronomy, are 2 great loves of my own ! ]. I Love what you have given us here. Thank you, most sincerely.
Yes, I also like to see videos filmed outside. As I spend several hours of nearly every day either gardening or out walking, makes me feel right at home while listening to a subject that's interested me since a young child.
Thank you Cool Worlds team for yet another gem. Great topic. And by the way love the outdoor wooded setting for the video. A refreshing change from having to look at everyone's home office! Stay safe and keep the great work coming...
Love your videos, huge respect! We need more people like you ❤️❤️❤️🇱🇹
Thank you very much professor! It's awesome to learn all this from someone with 100% passion. I've never ever had a teacher that cared so much about the subject, and that makes a world of difference
I've said it before, but thank you SO MUCH for this channel and your efforts in making it.
It captures my imagination absolutely! Please keep these amazing videos coming!!
Thanks! Bit slow this month with teaching restarting here at Columbia but should be back to videos next week
@@CoolWorldsLab thanks for your reply! 😁
I'll keep a look out for those new videos! 👍
I think this is my favorite channels on all platforms! You guys deliver us such great content, i almost feel myself a professor already, just by taking in your wisdom.
Our gentle Sun has given us a special home. Let us take care of it.
Yes piggypiggy pig. We have been given an amazing amount of 'The right Place at the Right Time'. We are tremendously luck to be here. And look at the news now. With all those advantages we've been given, hate is the God we have chosen.

Marxism has created self destructive behavior. The sun, moon and earth will be here long after the enemies of humanity are stomped into ground.
“Take care of it”....what could we possibly do to it?
How?
I really love the sun too. I think it's a great thing, but, take care of it? I really don't think it needs our help! LOL!
I absolutely love your videos; they're so well thought-out and scientifically approached, and the production value is remarkably high
Absolutely love this, more, more, more please, I'm so humbled to understand we are star dust
This channel is pure gold
As far as we can tell, for the vast majority of the history of life on Earth, it was single-celled organisms. Multi-cellular life might be extremely rare.
I think that is the case. But for some reason once multi arrives, it sure gives a show.
what you talking about, 4000 years ago people rode dinosaurs to work
N Strat Yes! And back then, our cell phones were made of wood and we'd have to make our own 'clicking' sounds when we were pretending to text. Contact lenses were also made of wood back then and splinters made them difficult to wear so we had to sand them very carefully and, well-being opaque-they made riding the smaller and faster dinosaurs quite unsafe. (Sssso glad they invented insurance soon thereafter...) Working under unicellular bosses did nothing for our job satisfaction back then but you sure could pack the little bastards into the boardroom like nobody's business. It was a bad day when you stepped on a whole team of executives because your contact lenses were of a denser hardwood under your sucky benefits and your dino wiped out on the way home all because you were texting your frustration into a small piece of wood when you should have been watching the road. 'Good old days, my ass': we really do have it good nowadays…
@@nstratford9073 yabba dabba doo
U are correct earthling👾😃
I came to hear your poetic voice again. Admirable research and narration
Hi, writing from Toruń, birthplace of Mikołaj Kopernik. Bit offended that you called him German. Great videos BTW, I really love them.
Tomek - nie ogladales Seksmisjii?... "Kopernik byla kobieta"! ;-) Moze sie czlowiek zle wyslowil, chociaz podejrzewam, ze to cos gorszego. A moze po prostu nie CoolWorlds nie lubi Kopernika? lol Pozdrawiam.
Just wanted to say thank you . A refreshing dose of honesty !
One of the best and most underappreciated channels on TH-cam by a long shot
this isn't the channel we wanted, but this is the channel we needed.
Easily the best channel on TH-cam! Outstanding videos.
BTW Copernicus was a Polish astronomer, not German. Interesting video as usual. Thanks
Lol As a proud polish person that was hard to hear 😠😤
Well. It's not easy to determine his nationality in modern terms. Generaly he was a German speaking Polish citizen.
@@MichaelMajeran true Poland and Germany have a very complicated history we've been invaded by them multiple times so a lot of poles were and are accustomed to the language places like Silesia still have German influence to this day
This is a wonderful & clear explanation as to how life on this planet, in this Universe has absolutely nothing to do with religion, and everything to do with the 'roll of the dice'.
One of the other ways in which it appears we may be "special" has been the discovery that we are in a void. A void being a region of space in which the density of galaxies is low, very low. Not only do we live in a void but our void is a super void meaning that it is a lot bigger than "normal" voids. And not just any super void, the largest super void in the observable universe. This presents the problem that our measurements of how fast the universe is expanding may have been thrown off by living in an unusual part of the universe.
If the universe is expanding and we can't travel back and forth even at light speed.
.
I assume.
Early life had a choice.
Go with the flow, or fight the tide.
.
But contextually since this is space, would it not be easier to just travel inward to the "center" since it is traveling towards you.
.
If u travel away it might be more difficult or easier.
.
The defining factor, the direction your galaxy travels and where the big bang emminated from.
.
The real question.
Where do we stand from the center.
.
Is life emminating from a circular safe zone from the big bang?
Or is it a time thing.
.
If life existed before us and is out there.
Would we find more in the edge or towards the center?
A bigger void than the bootes void?
I am so happy to have discovered this series of podcasts...please keep up the great work...very appreciated
Thanks but this isn’t a podcast!!
There's something about this guy's explanation of things. I've recently stumbled upon his videos, and I'm hooked.
His dedication and passion is admirable. I cannot believe this channel just has less than 500k subscribers. Guys, let's tell everyone to subscribe to his channel and support his research by not skipping ads.
Another fascinating 'special' piece that we've started to come to understand recently is the structure of our solar system. This may be a bias of them being easier to find, but we've found a LOT of solar systems where the 'inner system' (i.e. the Goldilocks zone) is filled with a couple massive gas giants, Jupiters or larger. No rocky worlds that might host liquid water and life there, at least not as independent planets. And even rocky, Earth-sized moons are likely uninhabitable, between the gas giants' radiation belts, the gravitational flux commonly seen in such moons in our system, and the extended periods of total solar eclipse as the moon moves into the shadow of the giant.
Our system has no such 'inner giants', and instead seems to host a slew of 'outer giants', something we again haven't seen in many systems yet. It is theorized that these 'outer giants' acted as asteroid shields during the more chaotic periods of the early system, allowing life an earlier start on Earth than it may otherwise have enjoyed.
Interesting for sure
Ive always been curious about gas giants, i mean wouldnt they just expand or disperse quickly rather then become a huge planet?
There is evidence that suggests that Jupiter was on an inward spiral towards the sun also but Saturn actually pulled Jupiter back to the outer solar system!
Possibly the best channel on TH-cam.
I absolutely love his work 🙏🏾great job!!
the only way anyone can dislike the videos on this channel are being someone who doesnt believe there's something beyond this world (no judging here... not right now at least..). It must be wonderful being instructed by professor Kipping..
Video is very interesting, I am glad to have valuable content like this on YT. Thank you for spotting and correcting Copernicus origin as he was born in Poland (Torun - there is university named after him) and died in Poland, and as a Polish astronomer he has contributed to the changes which are affecting our lives even today. Apart of Polish he spoken German, Italian, Latin and Greek. This made him open-minded. Great respect, I love the channel. 👍
In Polish - Mikołaj Kopernik
I now preemptively like these videos before I've even seen them. They're always interesting and I'm lapping them up.
Your videos never fail to amaze me. Thank you for making this!
Who else instantly hits the like button before watching a Cool Worlds video because you already know you will love it and don't want to forget?
Dear Mr Kipping, thanks for the presentation. Just like your other video on whether we are alone or not in the vastness of the universe, so too, in this one your presentation is superb and you manage to keep "neutral". I was expecting though to see towards which side you are leaning but no avail. I did come to the conclusion that the sun is rare, the earth is rare and we are unique and alone; based on your presentation. "The sun ripens a bunch of grapes as if it had nothing else in the universe to do (Galileo Galilei)" Thank you again.
The first minute of this is magical. It succinctly breaks down our Sun beautifully.
If you can't see how special the whole arrangement of this huge machine, you wouldn't believe it actually exists.
Everything is perfect for life.
No mistakes.
Also the sun burning for billions of years, it should have changed or run low on fuel, but what we will learn is that the whole universe is a huge machine, and energy goes wireless to where there is need and where it is abundant.
The possibility of all these factors going on with out a glitch, the moon being at the right place, the sun being at the right place and continuing to work as it has for billions of years.
We don't see the picture yet because we believe that it is good chances, nothing is as long lasting to be chance.
I am not even close to anything a scientist but my god he sure explains it to the core. Plus it's asmr to my mind. I think more when I hear him. Good job doctor. Keep up the good work. Enlighten us commons more about things we don't know.
I think our sun is rare, and that combined with what getting hit by Thea did for our planet makes it a quite unusual place.
it is fascinating how things that are vital for us can be dangerous and deadly at the same time. Instead of seeing the forces of nature entirely negatively, we should remember that they are part of a larger system that guarantees our lives.
Loved the video as usual but Copernicus was Polish. As a Polish person it hurt my soul when I heard you saying “German” 🙈
Sincere apologies, we added a correction to the description, closed captions and as a drop down card annotation at 2:30!
Cool Worlds oh that’s so nice! Thank you ! Will keep on following you. Love your content 😊
Also please note that depending on the time in history Poland has been both German and or Russian. My family history is "germanic" but the ancient family castle is located in what is now Poland.
What did the car say when it hit the telephone pole? Why are you so polish?
Malmquist bias has the auto caption of "Mom Quiz Bias" and I love it.
Thank you, Dr. Kipping, for another excellent presentation! I have believed that “Rare Earth” is probably correct . It seems that “Rare Sun”, as far as we now know, applies as well….
Thanks. Such a great video. Well ordered, nicely told with good visuals and a great voice!
Hey! You're outside today! Loving the scenery in the background man.
Oh thank you for this channel. On behalf of all those whose spiritual self is already out there exploring and colonising the galaxy, thank you
You deserve more subs, amazing!
Thanks for sharing knowledge. 👍 🍻 Didn’t finish High School, went to the Army. I love to learn new information.
"We live on a vast surface beneath which we cannot see." Such artistry.
I just love it. Your videos take me on a journey of wonder and discovery. They ponder important questions and are delivered in a way that makes it accessible to everyone. Well done cool worlds.
Great Demotions, what a great, humbling term!
Are we not special for existing at all? The fact that there is something rather than nothing is mind blowing to me
Amazing job as usual. Keep doing what you are doing.
There’s a lot of info on this subject, don’t stop with one . Even after 70yrs I have new questions , and questions never stop
that was simultaneously exciting and sad.
Thank You for your incredible videos
Why in the galaxy would any part of the presentation make one sad, I wonder? What specifically, andrew, has made you feel sad? Is it the part where he said Copernicus was German? That was unsportsmanlike.
Sad in the sense that so many unlikely events had to transpire to form our sun and this solar system and our planet that it is more than likely that we are alone in this galaxy. At least in the sense that we are the only macroscopic technological species
Excellent. Your delivery is really good. Keep up the great job. 🎉
How can someone dislike this typeG professor.. THANK U for yr video! I want more;)
The dislikes are flat earth believers
maybe someone was up set over finding out we not special! or brokenhearted over finding out we are mediocre! it is hard for some to trade in hubris for humility.
I'm sure others have already commented this but Copernicus was Polish! Haha
His non-latinized name was Mikolaj Kopernik. If I am not mistaken, he played a pivotal role in pushing heliocentrism into an accepted principal of our solar system, much to the chagrine of the Catholic Church.
A correction.
It doesn't take 8 minutes for a photon to go from the sun's core to the earth.
It can take up to a 100000 years to go from the core to the surface.
It then takes 8 minutes from the surface to the earth.
Noticed same error as well. Or more like omission.
Takes 7 to 8 mins for a photon to leave the surface and reach earth
Great video as always! You and your colleagues keep up the good work.
Man I wish I had the brains and/or the money to study under you at Columbia.
Thank you again cool worlds. The truth is refreshing. Fantastic! You are a true scientist!
Interesting video, thanks.
Would detailed observations of our 'solar siblings', HD 162826 and HD 186302 confirm or deny how rare the Sun is?
However im also wondering why NASA don't review or research deeper on the nearer Yellow dwarf star named Tau Ceti which is only 12 lightyears away on our solar system..
Its mass is 79% of sun and Luminousity of 65-70% of our Sun,it has three Rocket world (4 Planets confirmed)and two of those Rocky world were potentially Habitable, accordingly it was 7Billion years old(3Billion years older than our Sun)yet it still Cooler and dimmer than our sun cause its it has slightly less mass than our sun means it will live stable for another 2Billion years..
In my Opinion why not NASA put their heads on to Study Tau Ceti since its similar to our sun and has also a massive solar system similar to our own
Good Dr... love ur vids... always watch... know it's hard to produce... but appreciate... look forward 2 ur next.
I love your shows and think you're a brilliant scientist. I have also always thought maybe it's our sun that's different and why there is life here. Not the earth necessarily.
Two years after the fact, I still greatly appreciate these videos! Stay curious everyone!
Another interesting, informative, and excellent video. Even reducing the percentage to 0.5%, as stated near the conclusion of the video, given the astronomical numbers, we are still dealing with huge numbers. Another consideration and concern is the effects of even moderate increase in solar activity on, e.g., the atmosphere, animal and human health, the electrical grid, communications satellites, and electrical and electronic components. Such a solar event similar or greater than the Carrington Event would likely cause cascading failures and lead to a plurality of major worldwide disasters.
yes but only because we did not build for Carrington levels, but if too powerful it could/would blow atmosphere right off or microwave (ish) the planet periodically (both not good for life).
@@fredricknietzsche7316 carrington level flares are common, the fact that more and more stars are found to have a cycle of recurring x-flare or micro nova is slightly more disturbing.. if you are interested in such events which our ancestors might have witnessed thousands of years ago, i'd recommend this paper by Anthony L. Peratt: Characteristics for the Occurrence of a High-Current,
Z-Pinch Aurora as Recorded in Antiquity. this paper is one that makes you think and ponder, you are warned..
@@runs_through_the_forest suspicious observers has it right .
These are the greatest science videos on TH-cam
Prof. Kipling you are a beacon of common sense 👌
Cool Worlds and What Da Math are the two best to watch 💯
Questions. What is the true age of the sun relative to us due to its gravity? Do the sun flares we see occur much slower from the sun’s perspective?
I don't think the sun is massive enough for time dilation to be a significant factor.
Awesome channel... thank you @cool world
I ask this humbly, as I have no science background, but from my uneducated standpoint, is it possible that the 'Rare Earth' and 'Rare Sun' hypotheses exist co-dependently? I mean to ask.. is it possible the Mars sized object that crashed into Proto-Earth which purportedly created the Earth and Moon as we now know them to be also coincidentally occurred within the reach of a 'Rare Sun'? Can a 'Rare Sun" give rise to life simply by being a 'Rare Sun'?
How far out can we reasonably extrapolate this effect? Rare Sun, Rare Earth, Rare Solar system, Rare Quiet Spot on an Outer Arm of a Rare Galaxy in a relatively quiet parcel of space......? Could crunching these numbers give us a better idea of the possibility and possible locations of intelligent life?
I apologize for my naivete in these matters. I cannot speak intelligently about physics or mathematics or the like, though I wish I could. Your presentations of the workings of the Cosmos are captivating, to say the least. What intrigues me are the pattern repetitions in nature that seem to apply equally in the macro and micro worlds. Given the equilibrium Einstein's theory of relativity gifts to everything outside of a singularity, is it too far a stretch to use our galactic pattern, in its entirety, as the benchmark for where to look for life?
I don't have a science background, but after watching this, it does make me wonder if that is the solution to the fermi paradox. That having a rare earth that orbits a rare sun is so rare, that it only happens once every few galaxies or so.
@@SnootchieBootchies27 Thank you for the like. 'Rare' is a term used so frequently when referring to life on this planet and our planet itself. I think the math is going in the wrong direction. If you add up the rarity factors it would show how impossible it is that we are here. And yet here we are. Phx Bias

Bad news: "The ability to retain an atmosphere is related to the magnetic field, which is also driven by internal heating. Prof. Primack noted that the heavy elements crucial to radiogenic heating are created during mergers of neutron stars, which are extremely rare events. The abundance of uranium and thorium appear to be key factors, possibly even another dimension for defining a Goldilocks planet."
