What also fascinates me about Earth is the variation of terrain. We got dry deserts, wet rainforests, deep blue oceans, high monstrous mountains, etc. It's like multiple other worlds into one! Every other rocky planet we know of doesn't have features like our own home. The vastness, overwhelming size of our universe tends to make us forget about the interesting & beautiful features of our own world.
I often think about that. We also have hail, snow, rain, rainbows, lightning, sun, a range of cloud types, seasons, day and night cycle, rivers, large streams, seas, oceans,…. There is so much variety in the „dead“ nature alone, it’s truly stunning
But at the same time, the vastness of our universe, and even our own solar system, tends to make us forget that we may not have the most interesting & beautiful features. We may not be the only planet with such variations in terrain and weather. And, the features that we do have, pale in comparison to the features beyond our basic comprehension of other worlds even within our own Solar System and elsewhere. Titan has seas of liquid methane, Europa and Enceladus have global oceans underground which could harbor life. That is just within our own solar system. Janssen, or 55 Cancri E in the 55 Cancri System, could be made up of nearly 1/3rd of it's mass in diamonds. And, there are also some speculations that there are planets outside of our own solar system better equipped for life than even Earth, such as KOI 5715.01.
Hey man. Someone has straight up ripped off one of your videos on Pluto. They've basically just re-uploaded your video with an AI voice over reading the same script. The channel is called Beyond The Cosmos.
This is endemic on CZcams, but CZcams don't seem to want to do anything about it as it still generates ad revenue for them. Kyle Hill did an interesting video on the topic about a year ago called "CZcams’s Science Scam Crisis", if you're interested to learn more.
Hello Alex, you are absolutely right, this planet has so much wonder to offer. With the astronomy and space exploration it is amazing to learn about planets made of diamonds, or places where molten iron rains down, but after the initial surprise and novelty of such other worlds wears off, it is clear that the dynamics, diversity, natural processes and just beauty of this planet stands out. You said it - "Will anything in universe ever be so beautiful and welcoming as this, our home planet?" I love this so much! Also, I am really glad, that you've mentioned that plate tectonics is rare and unique and what it does for life. I haven't heard it often before. After watching Anton Petrov's video yesterday about the fact that plate tectonics may be the reason why the Fermi paradox is a thing, I'm happy to hear about its importance and uniqueness from another source. Thank you so much for all you bring to this world, Alex. Amazing education but also reminder of beauty and gratefulness!
I learned all this stuff in Meteorology school, and I need daily refresher lessons to remember it all. Same is true for many of my colleagues. Thank you, Alex! 😊
This video is very beautifully made and created, It reminds us how much beauty, how dynamic and important earth to us. But many people on earth don't appreciate earth that much, like Carl Sagan said "We succeeded in taking that picture, and, if you look at it, you see a dot. That's here. That's home. That's us. On it, everyone you ever heard of, every human being who ever lived, lived out their lives"
Imagine being an eternal conciousness roaming the cosmos for eternity alone. Seeing nothing (other concious life), knowing nothing, bored, lost, utterly alone. Every gakaxy, every star you visit.....nothing. Then one day in that eternity of loneliness, you discover Earth and think to yourself 'alas i have finally found heaven in a universe of hell'
An eternal consciousness? Oh, you must mean God. Let me tell ya, he didn't create all this to leave it 99.999~% void of life... I'm afraid life is everywhere in the universe, and God put it there for His pleasure...
@@Quickened1you say "god is the creator" and equate god to the eternal consciousness, yet the eternal consciousness "discovers earth", so the eternal consciousness is not god

This is why a colony on Mars will never work. The first people who are born on Mars will learn how amazing Earth is and curse the people who forced them to be born on Mars. Then they'll just end up coming back here.
I’m pretty sure they wouldn’t stay on Mars forever. We’d probably do something similar to the ISS where people go there for a few months or longer and then return to Earth. If not, maybe they live on Mars but are allowed to visit Earth every now and then and people on Earth could visit Mars every now and then as well. Or maybe reproduction won’t be allowed on Mars until we can find some way to colonize it and make it Earth-like (which comes with its own set of problems). But there are many other problems with building/starting a colony on Mars that people are actively trying to solve. Mother nature loves to throw challenges at us but eventually we find a way to overcome them even if it takes thousands of years to do so.
I seems without burrowing deep underground, humans would receive a lethal dose of cosmic radiation on Mars in a few years. Though that's enough time to get homesick.
Mars will not be settled to live there. Mars will be settled for mining and research, and all people that will go there will go by an incentive. Also, by that point travel between earth and mars will only take some weeks, if youre born there and want to move to earth it will be no problem.
@@tylerwright3950 Mars doesnt have this weak of a gravity, while they certainly wouldnt be top athletes for a while on earth, they would be fine and over time muscles would build up.
I think Pumbaa said it best. "home is where your rump rests" Home is where you exist with (relative) safety and security as well as friends and possibly family.
@ldubt4494 so, there's actually the possibility of living in the upper atmosphere of Venus, above the sulfuric acid clouds. It's potentially dense enough that it might be very plausible to build floating settlements. Or so I've read.
One thing that intrigues me is how the Earth has a 23 degree tilt. Perfect might be 22 1/2 degrees, as it exactly regulates a balanced set of extremes. 23, though, allows a couple days for weather patterns to minutely dwell, which creates a tiny amount of chaos to occur, helping create near equal sustainable rainfall and moderate air pressures(obviously not the soul reason for this but it helps).
As for nearby exoplanets, from all that I have read, and with a little statistical guesswork, within a 10 light year radius, there should be 5-15 habitable worlds around mostly red, orange, and yellow dwarf stars, and maybe 1 supermoon around a brown dwarf or a super Jupiter. Farther out, this proportion, relative to volume of space and density of stars, should be about the same.
Just the right amount of chaos. I like that. :) @@bryanbryan2968 Habitability requires so many factors to be just right that it's hard to even find what they all are. One which gets me is having the right amount of water. For all that we say Earth's oceans are vast, the science has found that we should have far more water. The Earth's surface was once covered in an ocean many miles deep. The search for a mechanism by which this excess water disappeared concluded with the discovery that a certain isotope of aluminium would have had the right energy output to boil off that much water and the right half-life to have decayed to the isotope ratio we now see. So maybe there are 5-15 worlds of a comfortable temperature within 10 light years, but many of them might be flooded to such a depth, they have no stable areas which aren't under pressure far higher than the bottom of Earth's oceans.
By far the most enjoyable videos on YT and 100% appreciate that there is no agendas being pushed, just info 👍❤️💕. Cheers and Bless those who understand our place in the universe
Pockets of intelligence that are rapidly evaporating, thus concentrating the intelligence in an ever diminishing number of people. This is very apparent in the US.
I love the ambiguity in the original comment: It doesn't actually say whether Earth has or doesn't have intelligent life. :D But on a serious and sobering note, scientists have recently learned how prevalent tyre dust is, and that the particles are small enough to slip through the blood-brain barrier, though we don't yet know what it might do to the brain. However, there's an association between lack of intelligence and petty crime, and I can't help noticing that petty crime is a far bigger problem in and near urban areas. But no part of Earth's surface is without tyre dust, and over 50% of the microplastics in the oceans have turned out to be tyre dust. I love cars, but there's increasing evidence that they're amongst the stupidest things humans have ever created.
Oh how I wish I were this innocent and naive, believing the French could be explained. No. They are an anomaly, a glitch. One that the lead dev God (capital G) couldn't solve so just claimed it was a feature.
@@user-gx1rk8yw6l Why? We only suffer due to human mismanagement and misrule. For instance, there have been entire societies which were non-violent and didn't overbreed. Arguments to the contrary are prime examples of propaganda in support of misrule. Having been alive for 50 years and having paid attention to older people when I was little, I can entirely believe the World Health Organization when they said, before COVID-19, "We're the sickest we've ever been." Propagandists answer this by questioning the meaning of the word "disease"; it's disgusting to hear! And I have reason to believe that disease is connected with overpopulation. Ugh! That's enough of problems. I could write a lot more, listing problems and evidence, but the birds are singing on this bright morning and I've got to get myself a tasty breakfast. ;) I'm hoping for God's Kingdom to end the mismanagement. There is evidence it's real.
These scientists and ancient astronomers from a couple thousand years ago were just amazing. Goes to show you, for as long as humans have been around, there has always been bright, innovative people.
3:46 it's 364.25 days. That means the year is shorter than we count which means there will a full day after 4 years not accounted for. If it was 365.25 days, we would have to remove some time from our calender every once in a while.
I feel like this will be played on a ship drifting through space in a few hundred years from now. As a generation grows up only knowing the vast emptiness of space.
I'm glad you mentioned tidal forces acting on the crust, not just the water. Tidal force acts on everything, it's just that the water moves because it can, but the thin layer of rock is under enormous strain because it can't move easily - a strain that changes direction four times a day. The planet is being constantly massaged and I believe this is the cause of the grumbling and groaning, the thousands of tiny earthquakes that occur each day. Convection currents in the mantle probably cause the overall directional movement, but as you say, it's likely that tidal forces enable or enhance this movement by constantly nudging it. On the time scale of plate tectonics, it'd be like a vibration.
"Keeping time can be more complicated than you thought" this is exactly correct. I didnt realize how little I knew about time until I began studying for a world I'm creating. The thing I thought would take a couple hours at most to study sucked me into a 2 month rabbit hole...and I may be more lost now than I was in the beginning, lmffao.
5:00 this is so crazy but im about 99.99% sure that I worked at this apartment complex. Everything about it looks exactly the same, seeing this just about threw me out of my chair once I saw it. Im almost certain. I worked there as an apartment maintenance technician back then.
1:07 “You may have heard people call the Earth pear-shaped, or even egg-shaped.” That’s wrong, of course. The Earth is _obviously_ “an oblate spheroid with a pear-shaped modification.” (I read that in my earth science textbook about half a century ago and never forgot it.)
it is also worth mentioning that more than half of the Earth's ocean water is at cold 4°C. Earth has quite a lot of cold water since the ice ages! inn the days of the Dinos, it wasn't so cold deep down!
People arguably formed religions to help them explain why we're here. Because the reality of "pure chance, no purpose" doesn't sit well with them as we're the only species on Earth capable of thinking like that. We're just the right distance from the Sun and have had the conditions develop over billions of years to harbor life. There HAS to be another planet out there in a similar location with similar conditions. Just by pure statistics alone, even if the chance is 0.0001%. It's still possible. I refuse to believe there isn't life out there in another form.
Your third-person description of the Earth, as a celestial body, is quite delightful. I'm known as a bit of space nerd amongst my colleagues and they are often surprised that Earth is my favourite planet and by my reasoning,...it's where I'm from! =) Also I reckon it's the best looking planet in our Solar System
Can we add having a semi molten core, creating a magnetic field, and a large enough moon to cause tides, and an ozone layer to the list of criteria required of a plant to be able to sustain life?
Great video. Another thing about our calendar is that not every 4 years is a leap year. I've spent way too long trying to type this explanation without it reading complete nonsense, that I just copied it from Google. "Every year that is exactly divisible by four is a leap year, except for years that are exactly divisible by 100, but these centurial years are leap years if they are exactly divisible by 400. For example, the years 1700, 1800, and 1900 are not leap years, but the years 1600 and 2000 are."
Another fact: The "Ozone Layer" is actually a theoretical construct to better describe its density as in reality the O³ is dispersed throughout the entire Stratossphere which is roughly 35km thick. Relative to that the O³ layer would only measure a few millimetres. yet it is a very crucial factor for life on earth.
The "Ozone Layer" would be that millimetre thick layer that in reality doesn't exist since it is dispersed in the Stratosphere. If, theoretically, you take all the ozone out of the Stratosphere and compress it, only then you would get it. It is just a gas like water vapor or oxygen in our Troposphere. Not its own "layer".
I had to laugh out loud at the earthquake footage around 13:00. I've never been in a violent earthquake, but if I ever am, I'm sure I would have the wherewithal, as the lady in the footage did, to risk going in for my coffee before evacuation
I'm mostly impressed with the substantiations in this video of my own late realizations that the entire cosmos seems to adhere to some divine plan of perfection and direction towards evolution based on a predetermined paradym of guidance from both the ultimate combined creative source and the variety of imaginative consciousness projected by sentient beings who just so hold the abilities of the imagination concepts
Interesting to learn that if the crust were smooth, then we'd have a surface ocean 3km deep. I wonder if some of the Earth-like exoplanets that have been discovered are purely ocean worlds, with the only 'land' available being frozen polar caps?
Earth is the densest planet in the solar system, with the densest inhabitants seemingly hell bent on destroying themselves before they have lived and thrived and discovered all they can. At least that's what I would be thinking if I was a Venusian... or Martian.
Yeah. I do hope to visit it someday. Things are just a little rough here on Proxima Centauri b. Jokes aside, I agree. It is truly something to behold.👍🏾
I don’t think so. The air pressure is more of a product of weather patterns, combined with the amount of air above it, compressing it towards the earth’s centre of gravity. So it would be more similar at sea level everywhere, even though sea level is farther from centre of mass at the equator.
1:00 That's a result of a misunderstanding of the word "geoid". Earth is spherical in first approximation, flattened by 20km on poles as the second approximation. If we picture the CORRECTIONS to the resulting "oblate spheroid" shape, and EXAGGERATE their size by a factor of 10000, we get something that from some directions may look roughly pear-shape. But it's just a visualization of corrections that are a hundred meters max, plus or minus. They get applied to an oblate spheroid that deviates from sphere 100 times more than that. So it really is basically a sphere, flattened by one part in 600, to a very high degree of accuracy.
The following is part of the opening for the TV program “Secrets of the Earth” on The Weather Channel: “We have discovered a remarkable planet; a planet of extreme weather, alien landscapes & bizarre phenomena. It’s the most complex system we know of in the universe. That planet is Earth & we are only beginning to unlock its secrets.”
The green color is due to molecular oxygen emitting between 500-550 nm. The atomic oxygen has two bright lines at 777 nm and 844 nm. So, they contribute to red glow. Nitrogen molecule dominates the magenta glow (300-400 nm)

No. They are an anomaly, a glitch. One that the lead dev God (capital G) couldn't solve so just claimed it was a feature.

really good video Alex, nicely researched and very detailed ✌️😎
I am not convinced; my girlfriend is pretty adamant I'm the most dense object in our solar system.
Get off your big fat mass and do something with your life

I will never cease to wonder at the universe, especially Earth.
Same here, though *I* would replace ''especially" with "despite"...
@@user-gx1rk8yw6l Why? We only suffer due to human mismanagement and misrule. For instance, there have been entire societies which were non-violent and didn't overbreed. Arguments to the contrary are prime examples of propaganda in support of misrule. Having been alive for 50 years and having paid attention to older people when I was little, I can entirely believe the World Health Organization when they said, before COVID-19, "We're the sickest we've ever been." Propagandists answer this by questioning the meaning of the word "disease"; it's disgusting to hear! And I have reason to believe that disease is connected with overpopulation.
Ugh! That's enough of problems. I could write a lot more, listing problems and evidence, but the birds are singing on this bright morning and I've got to get myself a tasty breakfast. ;) I'm hoping for God's Kingdom to end the mismanagement. There is evidence it's real.
So incredibly complex and beautifully perfect enough to work together
Always interesting and informative. Thank you Alex!
Can we get a playlist for all the new “our solar systems planets” series now that the remasters are complete?
This is one of the best videos out of many! Definitely a Saver! 👍😉
I think JRR Tolkin solved that monthly calendar problem with the Hobbits calendar way back in the 1930's
Man, watching your videos always gives me the urge to play some KSP
Fantastic video
Great video as always! Don't ever stop❤️🔭
These scientists and ancient astronomers from a couple thousand years ago were just amazing. Goes to show you, for as long as humans have been around, there has always been bright, innovative people.
Bros voice is angelic, love this dude
0:26 humans working to change that feature
No matter how hard us humans fuck up our planet, we can be rest assured life will outlast us
3:46 it's 364.25 days. That means the year is shorter than we count which means there will a full day after 4 years not accounted for. If it was 365.25 days, we would have to remove some time from our calender every once in a while.
This is one of the best video's I've ever seen about earth, and in 20 minutes. That's quite an accomplishment. Thank you very much!
Another excellent video about our fascinating universe. The production quality and visuals were superb. Thanks Alex 👍
I feel like this will be played on a ship drifting through space in a few hundred years from now. As a generation grows up only knowing the vast emptiness of space.
I'm glad you mentioned tidal forces acting on the crust, not just the water. Tidal force acts on everything, it's just that the water moves because it can, but the thin layer of rock is under enormous strain because it can't move easily - a strain that changes direction four times a day. The planet is being constantly massaged and I believe this is the cause of the grumbling and groaning, the thousands of tiny earthquakes that occur each day. Convection currents in the mantle probably cause the overall directional movement, but as you say, it's likely that tidal forces enable or enhance this movement by constantly nudging it. On the time scale of plate tectonics, it'd be like a vibration.
After all the talk of giant stars and super massive black holes, it is easy to lose sight of the fact that earth is not really a peanut.
I really like your voice, explanation of the stuff of space contents really match domain
I'm in love with space, and I fell in love because of your channel.
Keep up the vids man, they are great!
"Keeping time can be more complicated than you thought" this is exactly correct. I didnt realize how little I knew about time until I began studying for a world I'm creating.
The thing I thought would take a couple hours at most to study sucked me into a 2 month rabbit hole...and I may be more lost now than I was in the beginning, lmffao.
Earth is such a fascinating place to live and learn about.
5:00
this is so crazy but im about 99.99% sure that I worked at this apartment complex. Everything about it looks exactly the same, seeing this just about threw me out of my chair once I saw it. Im almost certain. I worked there as an apartment maintenance technician back then.
All these years, never thought earth was this complicated.🌎
Thank you so much for this video!
this series reminds me of the encyclopedia i had when I was a kid, chapters dedicated to each planets. Read it almost daily and memorized it.
What's the third sentence on page 68?
This would be a very good video to watch in 2nd Grade. If the students can stay awake listening to this guy's voice.
1:07 “You may have heard people call the Earth pear-shaped, or even egg-shaped.”
That’s wrong, of course. The Earth is _obviously_ “an oblate spheroid with a pear-shaped modification.” (I read that in my earth science textbook about half a century ago and never forgot it.)
Great video, as always, Alex
11:54. I live there
Too early for the video today!!
Lol
it is also worth mentioning that more than half of the Earth's ocean water is at cold 4°C. Earth has quite a lot of cold water since the ice ages! inn the days of the Dinos, it wasn't so cold deep down!
If the earth keeps spinning faster and faster, we'll all get thrown off it.
Which is the planet's master plan.
People arguably formed religions to help them explain why we're here. Because the reality of "pure chance, no purpose" doesn't sit well with them as we're the only species on Earth capable of thinking like that.
We're just the right distance from the Sun and have had the conditions develop over billions of years to harbor life. There HAS to be another planet out there in a similar location with similar conditions. Just by pure statistics alone, even if the chance is 0.0001%. It's still possible. I refuse to believe there isn't life out there in another form.
I have been to earth several times, personally. I always enjoy it.
Your third-person description of the Earth, as a celestial body, is quite delightful. I'm known as a bit of space nerd amongst my colleagues and they are often surprised that Earth is my favourite planet and by my reasoning,...it's where I'm from! =) Also I reckon it's the best looking planet in our Solar System
We really do live between a rock and a hard place.
Can we add having a semi molten core, creating a magnetic field, and a large enough moon to cause tides, and an ozone layer to the list of criteria required of a plant to be able to sustain life?
COME ON LET HIM GET TO 2 MIL SUBS GO GO GO
Love watching your videos when I’m going to sleep
Great video with beautiful and stunning visuals of how truly amazing the Earth is. 😎
Great video. Another thing about our calendar is that not every 4 years is a leap year.
I've spent way too long trying to type this explanation without it reading complete nonsense, that I just copied it from Google.
"Every year that is exactly divisible by four is a leap year, except for years that are exactly divisible by 100, but these centurial years are leap years if they are exactly divisible by 400. For example, the years 1700, 1800, and 1900 are not leap years, but the years 1600 and 2000 are."
Earth sounds interesting. Maybe someday I will go visit it.
Thank u soooo much for this doc
There 's no place like home!😎🤙❤
Home is where the hearth is.
Another fact:
The "Ozone Layer" is actually a theoretical construct to better describe its density as in reality the O³ is dispersed throughout the entire Stratossphere which is roughly 35km thick.
Relative to that the O³ layer would only measure a few millimetres. yet it is a very crucial factor for life on earth.
So it's a layer with higher amounts of ozone. doesn't sound like a construct to me
The "Ozone Layer" would be that millimetre thick layer that in reality doesn't exist since it is dispersed in the Stratosphere.
If, theoretically, you take all the ozone out of the Stratosphere and compress it, only then you would get it.
It is just a gas like water vapor or oxygen in our Troposphere. Not its own "layer".
A relief seeing a channel use metric system rather than the imperial ones. Thumbs up!!
you might enjoy videos made outside the US as a whole ;)
6:00 is the start of the 400 day cycle topic.
Wow the bot spam on the comments is insane. And youtube does nothing about them like usual...
Yup. Good ol’ CZcams not doing anything to better the platform unless it makes them more money. 😑
They're not going to fix that problem. They want all the traffic they can get.
I had to laugh out loud at the earthquake footage around 13:00. I've never been in a violent earthquake, but if I ever am, I'm sure I would have the wherewithal, as the lady in the footage did, to risk going in for my coffee before evacuation
I'm mostly impressed with the substantiations in this video of my own late realizations that the entire cosmos seems to adhere to some divine plan of perfection and direction towards evolution based on a predetermined paradym of guidance from both the ultimate combined creative source and the variety of imaginative consciousness projected by sentient beings who just so hold the abilities of the imagination concepts
Interesting to learn that if the crust were smooth, then we'd have a surface ocean 3km deep. I wonder if some of the Earth-like exoplanets that have been discovered are purely ocean worlds, with the only 'land' available being frozen polar caps?
Earth is the densest planet in the solar system, with the densest inhabitants seemingly hell bent on destroying themselves before they have lived and thrived and discovered all they can.
At least that's what I would be thinking if I was a Venusian... or Martian.
Well said!👍🏻
For the first time ever the thought of space made me feel terrified 😳
What a beautiful planet ❤
Yeah. I do hope to visit it someday. Things are just a little rough here on Proxima Centauri b.
Jokes aside, I agree. It is truly something to behold.👍🏾
@@elijahsmall5873 I want to visit Proxima Centauri B as well, but I’ll be homesick if I left Earth for 75 thousand years.
Since the equator is actually higher up than the poles does that mean the air at the equator is less dense than at the poles?
I don’t think so. The air pressure is more of a product of weather patterns, combined with the amount of air above it, compressing it towards the earth’s centre of gravity. So it would be more similar at sea level everywhere, even though sea level is farther from centre of mass at the equator.
1:00 That's a result of a misunderstanding of the word "geoid". Earth is spherical in first approximation, flattened by 20km on poles as the second approximation. If we picture the CORRECTIONS to the resulting "oblate spheroid" shape, and EXAGGERATE their size by a factor of 10000, we get something that from some directions may look roughly pear-shape. But it's just a visualization of corrections that are a hundred meters max, plus or minus. They get applied to an oblate spheroid that deviates from sphere 100 times more than that. So it really is basically a sphere, flattened by one part in 600, to a very high degree of accuracy.
Cheeky little end the ad there lol
The following is part of the opening for the TV program “Secrets of the Earth” on The Weather Channel:
“We have discovered a remarkable planet; a planet of extreme weather, alien landscapes & bizarre phenomena. It’s the most complex system we know of in the universe. That planet is Earth & we are only beginning to unlock its secrets.”
The green color is due to molecular oxygen emitting between 500-550 nm. The atomic oxygen has two bright lines at 777 nm and 844 nm. So, they contribute to red glow. Nitrogen molecule dominates the magenta glow (300-400 nm)
Best video ever Alex. Just beautiful, thank you.
😊❤️🌟Thanks for shining 👍❣️
