Theoretically, could the earth's rate of rotation be changed by strapping a huge sideways rocket to the earth and firing it?

    Theoretically, it could, BUT the rocket would have to move the earth a significant fraction of the earth's velocity which is opposing the force of the rocket, which would be impossible in terms of practicality given that the larger an object, the greater its inertia.

    No---as it would be unlikely we could gather enough resources to build and FUEL a rocket BIG enough to counteract the MASS and spin of an 8000 mile in diameter PLANET.

    Simply running in an east/west direction will have an affect on the earth's rate of rotation. The affect will be immeasurably small but there.

    Yes, any force will have an effect.

    Will it have much effect? Probably not...

    It is not possible.No rocket has the capacity to modify the movement of a planet like earth.

    Theoretically, if the rocket was big enough (like 10,000 miles long and a diameter of about 1,000 miles), and if theoretically the exhaust was out of the atmosphere, and if theoretically it would have enough fuel, and if theoretically there was a strong enough strap to attach it to the earth, and if theoretically the rocket was structurally strong enough to withstand the thrust, it would not only affect the earth's rotation, but it could also break it free from the sun's orbit and we would be on our own path through the universe.  At least something similar happened to the moon in Space 1999...Remember moon-base Alpha...

    No, a rocket works by expelling burnt fuel out the back at high speed.  The angular momentum of the burnt fuel would be quickly transferred to the atmosphere and then to the earth, thus canceling momentum change that might be caused by the rocket.  You might get a little change from a rocket engine anchored to the surface of the moon.

    Theoretically, yes.

    What would you anchor it to and who would be left alive to see whether it worked?

    Theoretically yes, but that would have to be one massively huge rocket.  And why would we want to do that anyway?
