      .@esjabe If all cars aligned west-to-east & floored it, would there be enough torque to slow Earth’s rotation? // Yes.

      .@esjabe But you can’t cheat laws of physics. When the cars turn or stop, Earth fully recovers the lost rotational momentum.

          @neiltyson @esjabe However, if all the cars turned on their headlights then the photons would carry away angular momentum into space.

          @neiltyson @esjabe What is it that returns the rotation to equilibrium even once it's been slowed?

          @SirLandonJ @neiltyson » The force required to produce the momentum would be required the destroy the momentum. Thus equilibrium.

          .@neiltyson @esjabe You don't lose rotational momentum to friction or whatnot like you do kinetic energy?

          @sciencenotscary Momentum is only converted to other momentum, it's a constant.
