If my description above is correct, then what the probes designers are saying is that the vacuum is able to both impart motion to matter, and also hinder it - i.e. inertial forces. Another simpler way of saying this is that the vacuum is viscous.

This also says that any mass moving

*through*the vacuum must have an influence on the vacuum (as does the earth's rotation, if it does) - so therefore common sense tells me that if this is true I should be able to calculate the resistance to motion of the earth say, as it orbits the sun.

I can calculate the force that imparts the motion, but how do I calculate the force that restricts it?

To be precise - an expression of an opposite force (F = mg)as Newton said, is inadequate, I want to calculate the force in terms of the vacuum and it's retarding effect (the inertia)if it exists.

Any help?
