When you slow down the earth's rotation every minute

[@Serenity_Dee]

0:48 I have read a _lot_ of case reports in medical journals, mostly out of curiosity, and one of the biggest takeaways for me is that humans are, in fact, simultaneously terrifyingly fragile and astoundingly resilient. The things that have killed people are just as surprising as the things people have survived.

[@lief9100]

So, to explain the end. The reason the lack rotation didn't result in two-face when it was really long was because the orbit was still changing where the sun hit. That's also why around 320 was the most extreme, it was the closest to 365, one year. You'd need one rotation per revolution to become twoface. Also known as being tidally locked. And the snowball at the end was because increasing the orbital period also moved the earth farther from the sun. You can see in all that mess around the sun that mars and everything is much closer, and the next planet outward from earth is saturn after he increases the orbital period.

[@Thunder_Axolotl]

Yeah I noticed that at the end and was confused for a sec

[@twisted_mentat8810]

Challenge idea: graystillplays has the ability to cheat, but so does the board. The further he gets into the board, the more the board cheats to try and stop him from winning. There's plenty of checkpoints when he starts, but if he cheats, checkpoints get removed from the board.

[@dragonclaw4159]

And while you're probably thinking about the chaos mod, the difference here is the cheats actually target whatever graystillplays is doing. If he's driving a car, suddenly the roads have been replaced with a trench of water or his car is gone, as is every other car.

If the life % is down to 1% it's not going to be humans: we're too environmentally sensitive. There is no situation where it's humans surviving -230 or +200 temps. But certain simpler extremophiles we've seen in crazy environments on earth might get away with these insane situations.

Fun fact, even with 0 rotational speed, because of the orbit of the Earth, every part gets some Sun (which is visible at the end). The half Sun half darkness sceranio happens when the Earth is tidal locked, and the rotational period is one year, hence the spot was the biggest around 320 days. Real planets exist with this configuration, and they maybe suitible for life at their twilight zone.

[@CalmestRaccoon]

This is realistic too. Millions of years ago (dare I say billions), each day on Earth lasted only 6 hours. And that number gradually increased because Earth started spinning slower and slower. And it's still slowing down, though mankind will be long extinct by the time we realize this is actively happening.

[@whereismycup]

A few million years ago earth was at some 23.45 hours if I remember correctly

[@CalmestRaccoon]

@@whereismycup Yep. The Earth was at one point hit by meteorites for 20 million years straight, and these meteorites contained water particles - the water we have nowadays. I think that these meteorites and the fact that the Earth was only just formed were causing the planet to spin really fast, and it gradually slowed down as time went on. I feel like 500 million years from now, one day will last 25 hours instead of 24.

[@Metallica0475]

.997 is correct for the base rotation, it is why we have a leap year. The actualy lenght of day is 4 minutes less than 24 hours (24*60)-4 = 1436 minutes. 1436/24 = 59.833333333333333/60 = .997222222222222222

[@AlexWaterElement]

If the earth stopped spinning, i will just go to mars

[@wallacengineering8096]

I heard something about the rotation of the Earth being very important for heat because of the molten core in a science article many years ago. Its extremely hot down there and as you slow down the Earth's rotation, so does the core and its heat. But eventually, when it gets too slow, the side facing the sun is simply cooked by the sun. Also it looks like it maybe moved a bit farther from the sun for some reason even though you didn't change the orbit? Weird... By the way, peak GreyStillPlays content is still definitely the My Summer Car series, but its good to see Universe Sandbox back 👍

[@Lightman0359]

There was a Nova/NatGeo documentary on this. It was in their catastrophe what if series, it was called "Aftermath: When the Earth Stops Spinning". The rotation period slows gradually to match the orbital period, so that like Mercury, 1 day = 1 year, with the northern hemisphere's day being at Perihelion [Nothhern hemisphere summer] and the southern hemisphere's day at aphelion [NH winter] for the harshest effect of 6 months of daylight on the most people.

[@arutirauland]

1:11 the rotational period isn't exactly 1/day initially because Earth needs 23 hours and 56 minutes to complete a rotation around itself, rather than exactly 24 hours. That is also the reason why every fourth year has an additional day.

[@Cane4092]

Yeah and since the moon is moving a cm a day year away from us,which slows down the earth a little, one day,long after we are dead, humanity will no longer have to suffer being born on a leap day

[@Two1124]

You know it’s going to be chaos when gray posts

[@nosbig98]

The temperature dropping because the Earth is getting more distant from the Sun. As the rotational speed decreases, the centripetal forces are weaker, leading to larger distance in the orbit of Earth.

[@thesupervideogamenerdmore3171]

Wow, Universe Sandbox is very attentive to the smallest stuff.

[@Neo-vz8nh]

that is not true. The distance increased because he increased the orbital period,, which leaded to higher orbit. Rotational period has nothing to do with the orbit.

[@onorebakasama]

Not true. The increase in the orbital period (at the end) is what moved the Earth away from the Sun, and that's because a larger orbit requires a lower orbital speed to match the weaker gravitational pull of the Sun; gravitational pull weakens with distance to a body. As for rotation (the majority of the video), it got colder (and hotter) because the low rotational speed meant the a single point on Earth had more time to cool down or heat up under the Sun.

[@Mtscl32]

Not true, if anything slowing down the earth should reduce tidal forces as the offset bulge created by spin should be reduced as well. In fact this is why tidal locking is an equilibrium state

Yes, there will be parts of the board where Gray can have a break, and yes, there will be a teleporter at the end, where Gray has 2 chances to get the correct road path correct (Which won't despawn) if he fails at getting the correct path correct then he just need to restart the map. AND... yes, it is possible, and what I mean by two hours is that no matter what difficult board he plays, would probably take 2 hours, but Zach just edits out most of it, so it's suitable for a short yet entertaining clip) Yes, there will be a 10 second timer before the board slowly disappears and there will be parts of the board that won't disappear and there will be a script at the end where it teleports Gray to the beginning and resets the board, and there'll be 3 teleporters, he'll have to guess correctly, one crashes his game, one forces his game to force restart, and the final teleporter gets him the win.

[@mabus4910]

1:16 I was wondering why the rotation starts at 0.993 days. I think I have found the reason. Since the Earth travels around the Sun in its orbit, it has to rotate slightly more than one full turn on its axis for a given point on the Earth to face the Sun again. When the Earth completes a full rotation relative to the Sun (a solar day = 24h), it has actually rotated slightly more than one full revolution relative to distant stars (a sidereal day = 23 hours, 56 minutes, and 4 seconds or approximately 0.997 days).

[@mabus4910]

If I am correct, setting the day in Universe Sandbox on more than a year would make earth spin backwards. (I think that is happening in 16:54)

[@UnauthorizedRosin]

Kind man restores the ice caps

[@ephemera2]

When the rotation is one year per day, meaning it's the same amount of time it takes to go around the sun, it's called tidal locking and only one side of the Earth faces the Sun in the other side remains in permanent Darkness though that is a shity coordinate transformation considering the Earth is technically traveling a straight line or a geodesic so it shouldn't be considered to rotating when it's tidally locked

[@Simmlex]

Of course the earth is getting colder. The sun is not getting hotter so the sunlit side is getting the same amount of energy/heat, but the dark side is getting increasingly more and more time to radiate the heat away with no replenish, so it becomes a vicious cycle of the cold side losing heat and the planet trying to find a temperature equilibrium between the cold and the lit side. but since the dark side getting no other heat source other than the lit side, it's like as if you opened all the doors and windows in half of your house at a winter night and then got surprised your house is cold despite the heating being on on the same temperature as always. And once you reach 365 days/rotation, the earth is now tidally locked to the sun, in other word, the same side always faces the sun. At such a planet life would only be possibly at the area where the dark and lit sides meet at an eternal dawn/dusk and winds would be insane.

The reason, why it startet at 0.997 of a day (or rather 23h 56min), is because it is a SIDEREAL day (pronounced SI-DE-RE-AL, not side-real). This is an earth rotation, that takes the orbit of earth around the sun into account. After all, in the ~24h it takes to rotate around, the earth has moved and the sun is then in a different place.
