Bear with me, because of all the time spent already.

Here's the first one.

movement is relative, except when it is absolute.

If you are going to count the rotation of the earth as speed, then the speed of the earth around the sun also counts as speed. So when the point on the equator is going with the earth's speed around the sun, the point is moving at 68.000 mph, then reduces to 67,000 mph when it is 6 hours later, reduces to 66,000 6 hours later, when it is opposite the motion, then 67,000 mph again, then 6 hours later 68,000 mph.

This claim is just as valid as the 1000 mph claim.


67,000 mph = earth's average speed around the sun

This "going east" thing is an entirely different matter.

What happens if you reverse the polarity?

That was not moving

So to sum up this thought experiment

Since movement depends on the observer, an object on the equator is either not moving, or moving

The speed and direction used when explaining it is moving

Can only be observed from an actually moving POV, but it is impossible for that POV to observe a constant motion of the object in regards to speed and direction

The direction of the theoretical motion is “East”, which is the real problem here

If you use the observer to define East, or rather it’s relationship to the North Pole, that same object which at the start is observed heading East, is going to be headed west in 12 hours

If you use the object to define East, or rather it’s relationship to the North Pole, which is what we usually do, then East constantly is a different direction for the object, which is really hard to explain

Unless you watch an animation of it from a POV, that does not show movement, but does show direction, and then your head explodes

In any and all cases, the speed of an object on the equator is never 1000 mph East, except when you think it is
