We just watched the Futurama episodes where alien cats stopped the Earth’s rotation, and they fixed it by making it rotate in the opposite direction.

    Regardless of how fast or slow you reversed the direction. Pretty much every weather pattern and ocean current on the surface of the planet would be thrown into a massive calamity. The Corolis effect and momentum imparted to surface fluids around our rotating ball is a huge, huge deal with weather flow, like the “jet stream”. It directs how storm systems (the flow of water that all life depends on) form and track and which typical track they take as the rotation of the earth is constantly deflecting them. There would be huge, unending storm systems as existing patterns now crashed head on into new ones, with storm fronts spanning entire continents. Even after the storms subsided and it settled into a new normal after 20, 30, maybe 50 years… agricultural breadbaskets would be either destroyed, completely inhospitable to their original crops, or stranded in drought. And human civilization would likely fall with them.

    Lois Lane would be resurrected and unburied by rocks if there had been an earthquake caused by a nuclear strike shortly before this happened.

    We all die, a lot us rapidly when the water keeps moving across the rock that just stopped and super tsunamis a good portion of the planet. The rest of us die slowly as the weather patterns are ruined for likely decades or centuries and we starve due to crop failures and the fact that the worldwide logistics we depend on is forever gone.

    Edit: actually I thought some more, if it’s sudden then we’re all crushed by flying into the air into stuff at 1000 miles an hour when the rotation stops. If it’s gradual then we all starve since the weather is ruined

      You forgot about air. If the planet suddenly rotates in the other direction, it would level everything, and the probably turn the planet into a molten marble from the friction.

      I don’t know. Couldn’t it be gradual enough that we barely noticed the acceleration changes but still only take a couple of hours?

      But OP asked a different question. Not what happens when earth stops spinning but what happens when earth spins in the other direction.

        The answer is largely the same if you make the same assumptions though, just roughly twice as bad because not only does the earth stop and everything not attached goes yeet, but everything attached starts moving just as fast as you in the opposite direction

    It changes the way stars appear to move for us. Astrology teachings would have to do a full 360 degree turn to retain their accuracy.

    I can’t say this with any authority, but I think the biggest effect would be in weather patterns and the subsequent downstream effects of having different weather.

      Nah, the biggest effect would be in every single thing at or above ground level being instantly shot eastward at somewhere between 0 and 1,000 miles per hour. After that the weather is pretty much irrelevant because anything that would experience it would be dead as shit.

        Only if the rotation would stop immediately. A slow deceleration would not let that happen

          I mean, sure, there will be some people on the lower end of that 0-1,000 MPH curve that are not in very close vicinity to any objects to splort against. Inupiat, Aleut, Sami, Yamalo-Nenets… anyone inside the arctic circle should be relatively fine, speed-wise.

            Ehm, good one… what would happen to all satellites and ISS? Would all that junk still spin in the same orbit or would it be flung out into space?

              I think they would be going on with their business because gravity would be still the same. IANAP

    The earth’s magnetic field would probably ‘follow’ and change it’s direction. But only a while later and very slowly. During the change, that would leave us without a magnetic field for some time. Then we have lots of cosmic rays hitting us, damaging some of the life on eath.

    Need more info. Does the earth immediately stop spinning and start spinning in the opposite direction? Or does it gradually stop over an arbitrary amount of time and reverse directions? Haven’t seen the episode…

    Only a change in rotational speed would be bad. If earth were to rotate in the opposite direction since the beginning it would behave just like today.

      That was my thought. The only major change I could see happening (besides the cataclysmic events from the change) is the direction of sunrise/sunset.

        Exactly

        Proof: define Antarctica as North. Now earth is rotating in the other direction.
