I think the experiment of Newton's bucket is wrongly criticized.They deny the absolute velocity,it is right ,but they agnore the absolute nature of motion,which is not relative to other system,but is relative to the thing itself at the previous adjoining instant.Such as the expanding of universe and radiation of the sun.
The expanding of universe can't be described by coordinate system,because it is a motion which is relative to itself(at the previous instant),and our universe is different every instant,it can't be threated as a inertial system.And because it is the biggest one whick contain everyting existed in it,so we certainly can't find another coordinate system to describe this motion.
So,we deny the absolute motion for which we must find an absolute coordinate system,and we confirm the absolute nature of substance which is relative to itself.Some people will say that if we use the thing itself as reference,we can't get any movement,because: A-A=0.But A(t+Δt)is not equal to A(t).So the thing itself can and must be the really most meaningful reference.Because the reason of motion of substance is not out of the thing but in the thing itself.Inertia is an inner reason.
