Either something is moving or it isn't, regardless of how it appears in your relative frame of reference.

All right, then. If what you say is true, then there might likely be some motionless object. Is anything in the universe motionless? Can you point to any single object and say with certainty, "This object is motionless in space. This object is stationary within the fixed, absolute frame of reference"?

And if what you say is true, and there are things that are moving and at least one thing that isn't, how can you tell which is which?

Who says that we *can* tell?

I'm simply pointing out that Reality cares not a whit for perception.
