The end of this video says this is the last in the series, but actually Neptune and Venus are not released yet. I just had some problems with the ordering in production. Don't fear, Neptune and Venus will still get done. Check out Manta Sleep here tinyurl.com/3amtx2k3 and make sure to use ASTRUM for 10% off your order!

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.

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.

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 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.

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.
@eekee6034
@eekee6034 20 күн бұрын
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.

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'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.

"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 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, you're looking at the Drake equation wrong. You shouldn't be asking how it is that all these things had to be right in order for life to happen. Life fits the environment. Not the other way around. It's a geometry problem. There's an infinite number of ways that a complex emergent system can come out of an environment. We know of one of them. One data point is not enough information to form a model. So from our perspective, life is miraculous and improbable. But that is an illusion

I'd like to subscribe to this belief but who says "There's an infinite number of ways that a complex emergent system can come out of an environment"? Complex as in life as we know it. The incredibly stable yet also ever changing nature of earth is what seeminly allowed complex life to emerge here. Perhaps there's some very simple life forms dwelling around an undersea hydro thermal vent on some wasteland of a planet but the goldilocks is real with earth and I just can't see that many random variables lining up often even in a galaxy with a trillion suns.

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.

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.

@@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.

8:44 honestly i dont believe that distance from the sun does not matter here. Because in January we in EU, US and Asia have winter, but Australia has summer. And now compare how hot summers are there and how hot summers at same latitude are in EU. It definetly should be one of reasons why australia is hell at summer.

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?
@SnootchieBootchies27
@SnootchieBootchies27 29 күн бұрын
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.
