xxein: There is only one vantage point. The universe (and/or/if
beyond) exists. To assume anything more is to invent reason based
on
nothing more than a wish.

There can be more then one vantage point, one observer sees a ball
coming towards him another sees if flying away from him.

The ball, from virtually one point in space.
sees two ~observers~ pulling fore and aft
and a matter filled universe pulling in all directions.
(~matter there influences inertia here, Mach)

According to Mach, matter *makes* inertia. However, no correctly working
model could be made based on his hypothesis.

circumstance that acceleration induction in accordance with
the gravitational field equations really exists, although of
such slight intensity that direct detection
by mechanical experiments is out of the question. >>

gravitomagnetism. >>

Sue...

Sure. Now please explain how Mach's hypothesis correctly predicts the
inertia of a spacecraft as function of the distance to the sun.
