@@Airdel At the time, there were very few species on Earth. Most if not all were microbes.
@@Ben_Kimber ishould have specified "most of the bacterium kingdom"
@@Airdel XD
What you said still made sense either way.
To be fair, the painting the seas red was a good thing because it meant they were releasing oxygen in to the water, rocks and later the atmosphere
The glaciations, though...not so much

its amazing to think about how many different worlds this planet has been throughout its history
And life too and how differently it's adapted and evolved and some even gone due to those conditions not being present.. This is why i think life could happen on other planets because our conditions have been right a lot of times and this is a infinite universe so it's only a matter of time before otherworldly life is found (Either alive or via fossels.)
that resonance phenomenon is fascinating
Even the moon position is at scale
This deseve more views.
This is super interesting! The rotating Earth here gives a bit of extra visual information that the Algol video was lacking. And I love how the graph is just disrupted by the Earth, haha. Great job, Geo!
Hey! I think I saw you on BFB 28's new comments section one time!
@@scopex3592 That’s entirely possible, seeing as I voted on BFB 28. I’m mainly in the TWOW community, though.
When I saw your profile, I knew you watch BFDI
To me the rotating view is hugely superior, why is it so rarely presented this way? This is the only video I’ve seen.
stop bullying
This channel is underrated, this needs more recognition.

I especially like how you took Algol's map, this video is just too perfect
Underrated video. Algorithm needs to get its shit together and recommend this to more people. Great video.
Absolutely fascinating. Finally all the data I was always interested in, put together. Thank you.
You could also have included the data about the inclination of the axis through earth history (like the animation of the axis, and the measures of its tilt)
0:09 How were you able to render Algol's map to your globe?
@@duckface81 the video is already 3D
I reprojected it with a python script.
@@geobica with what app
@@tofegamer03againgolddelete64 It was a custom script I wrote in python that converted from Mollewide (which algol used, probably because it's an option in gplates, which algol used to make their video) to a 3D perspective. You could probably do this more effectively with a GDAL script, though I actually hadn't learned how to use that last year when I made this video.
@@geobica If so, What could be the code, and what GDAL script? (optional)
This was in my recommended, I love this vid!
Beautiful and fascinating. Great work, thanks so much!

Name a single month that has 35 days, I dare you ;)
Essentially the daily atmospheric tide due to the suns warmth coincides with and opposes the oceanic tide which opposes the Earths easterly rotation. The size of these 2 opposing forces are on average equal at day length 21 hr. At other days lengths therefore the atmospheric tide must affect the part of the Earth that is not experiencing drag from the pull of the moon....although I don’t picture it exactly.
I love this video so much!
Amazing. Would have loved a bit more explanation on various features we see and that we have no idea about such as colours, sudden colours changes etc
@@geobica That's a very good one
"Unless humanity does something about it that is..."
Bro like what? attach rockets to the planet? I don't think planetary rotation is a problem we're gonna find a solution for
we've already unintentionally fiddled with the rotation of the earth with dams. I can see there being projects to deliberately change the rotation in the next thousand years. and there's millions until it becomes a problem
F**k up the moon. Smack some asteroids into where they shouldn't be. Two of the most likely ways i think. Sure it's very distant future, but not impossible.
Humans always find a way to screw things up. So don’t hold your breath. World ships are a thing.
Fantastic and informative. Wow.
Thanks RUclips recommendations
very interesting. thank you!
*Technology recording Earth*
Earth: *spinning* What are you doing?
Technology: Err, nothing.
Earth: You sure?
During the precambrian resonance period would the wobbles in day length occur every few days or every few hundreds of years?
In Bartlett and Stevenson's simulation the wobbles last tens of millions of years and bring the day length to about ten minutes away from the average in the resonance period, though I'm not knowledgeable enough about the physics to know how accurate that is.
Wow this is totally underrated
That's very nice.
I liked the part where the Earth rotated.
So help me I thought of NASCAR.
"And, wait for it! He makes another left turn! Unbelievable!"
Oxygen levels throughout time, or the atmospheric composition actually, would be interesting!
look in the disc there is a vid called history of earth
Can anyone explain why the Earth’s day stabilized at 21 hours long?
The gravity of the moon works to decelerate Earth's rotation (via gravitational tides) while sun's heat works to accelerate it (through thermally driven atmospheric tides).
Gravitational tides happen because moon's gravity creates a small bulge on Earth facing the moon. When the earth rotates slightly forward (faster than the moon orbits) the moon pulls back on that bulge, slowly decelerating the Earth.
Atmospheric tides happen because sun heats up the atmosphere during daytime, lifting hot air high above the surface. Later during nighttime when there is no sun, that hot air descends down on the surface, converting heat energy into kinetic energy, slowly accelerating the earth.
These two were in resonance, which means they were equally accelerating/decelerating earth's rotation therefore always keeping Earth's day 21h long. When the Earth froze over though, the atmospheric tides were no longer effective so moon's gravity won over and decelerated the Earth out of resonance therefore deceleration continued to this day even after the atmosphere returned to normal.
@@ihato8535 Ohh thanks. I didn't know about the atmospheric tides.
@@ihato8535 Can you tell me if the hypothesis of rotational stasis from 2.6 to 0.6 GYA ever became widely accepted? What is the state of the question in 2021?
This is epic

Very informative and fascinating video. A mandatory addition to the wonderful Algol video. Is the resonant-period of constant daylength only a theory or it is widely accepted?
That's a good question-there hasn't been much research into it beyond the papers I cited, though I also haven't seen any research that contradicts it. It's possible to estimate the actual day length with tidal rhythmites and stromatalite layers, though there isn't much data for the pre-cambrian. All that I've seen of it though seems to line up with what the simulation predicts.
wonderful movie
Hope the Algolrithm picks this one up soon, nice work ^^
it has already
@@orthernergjy
Bhhbjj
You're the next Algol!
I think I see why the year was so long like 700 days long, it was probably because of the shorter days on earth back then
I was so dumb in approximating a year with our current day and wondering if the Earth was further away from the Sun or something weird hahahaha
When you see the white line moving it is forming the Eon,Era,Period and the Epoch
It changes when the white line gets to the end of it and so on
How did it hold its stable rotation and how come the drop of earth’s temperature released the earths stable rotation ??
Did the Earth has a different tilt of rotation in the past, or this is just only in animation? It seems like it was tilted to the left before, which it's tilted right for now
there's no left and right only the angle

U used Algol… and it’s really cool!

What baffles me most is that the Phenerozoic with all the more known time periods, Cambrian, Ordovician, Silurian etc are _only_ like 1/8th of the history...
I liked it when I was in that stable 21-hour resonance. It was peaceful.
To me the rotating view is hugely superior, why is it so rarely presented this way? This is the only video I’ve seen.
Because people want to see the continents in their entirety, if you use a globe projection then you only see half of the planet

Wow 🤩
Can we give it up to the time lapse guy that sat there and took all those pictures of earth over billions of years so we could have this seamless time lapse?
Can i have Equirectangular Projection in the video
The music: playing the piano randomly but with only black keys
Always strikes me that the earth and our solar system have an expiry date on it.
During the moons formation the model didn't even budge ! I wonder how many coronal mass ejections hit the earth ? Especially since we know now they can push the magnetic field around
A M I S E E I N G M O O N
Oh wow
I've seen one YT representation claiming that when the moon was formed the Earth's daylength was maybe 4 hours. Another one claims 6 hours. Several claim it was one long steady lengthening, others claim the day stopped getting longer for quite some time and then started getting longer again. Very confusing! All based on scientific facts and discoveries of course... but they seem to contradict each other.
Wow
Earth starts spinning slower than...
- Haumea (3 h 56 min 44 s): always has
- Ceres (9 h 4 min 27 s): 4333 MYA
- Jupiter (9 h 55 min 33 s): 4216 MYA
- Saturn (10 h 32 min 36 s): 4113 MYA
- Neptune (16 h 6 min 36 s): 2909 MYA
- Uranus (17 h 14 min 24 s): 2649 MYA
- Makemake (22 h 49 min 36 s): 219 MYA
(Current rotation of the Earth - 23 h 56 min 4 s)
- Mars (24 h 37 min 23 s): Future
- Pluto (6 d 9 h 17 min 32 s): Future
- Eris (15 d 18 h 51 min 42 s): Future
- Mercury (58 d 15 h 30 min 30 s) and Venus (243 d 0 h 33 min): Never - will tidal lock to the Moon before reaching it.
Caveat: this assumes that the other planets have never and will never change their rotation periods, which is very likely false!
2:58 27 billion years from now, a day of the Earth will be 1128 hours long.
0:51 cute moon :D
Oh I see that
No mention of being hit by the protoplanet Thea?
What made the earth lose the rotation speed ?
the tides of the moon:D
@@FisTheDucc how is Jupiters rotation speed still six hours long if it has like 600 moons still pulling on it
These moons are rlly smol comparred to big boi jupiter:D@@titanicbigship
Why is the orbital period changing so much? Did the semi-major axis change that much? if so, how and why? Earth must have wandered inwards then...
It didn't, the length of the year didn't change much, but since the day was shorter, there were more days in a year. I should have been more clear about that in the video
@@geobica Oh, yes, of course. :D Thanks for making that clear. No, actually I should have thought on that, because you mention "Then" after the number of days.
Brilliant. Only a matter of time until CGP Grey steals it.

History of the earth
can i find the textures
They used a python program to convert the Mollweide map projection in Algol's "History of Earth" video to make it into a sphere
2:52
What's the state of the question now? In 2021, how is the hypothesis of rotational stasis from 2.6 to 0.6 GYA regarded?
I have not seen anything to contradict the hypothesis. A few months ago though, the paper "Possible link between Earth’s rotation rate and oxygenation" (www.nature.com/articles/s41561-021-00784-3) proposed that the stable rotation rate would line up with models of oxygenation levels. Essentially, the stable rotation rate and oxygen levels would both coincide with the Boring Billion, and the phenomena may be linked.

ok so there's one thing i don't understand, why is there two labels for month?
Top one is counting in number of 24 hour days, bottom one is counting in number of days at that specific time in the simulation
@@George83_Thomas thank you!!!
And the future of the Earth's rotation?
Look at the credits
Why was a year so long back then ? Don't get it.
The year was about the same length, it's just that there were more days in a year because the days themselves were shorter.
