Ray Tomes:

That maybe so.

Look at reference:

How does the cosmological constant fit into general
relativity?

http://super.colorado.edu/~michaele/Lambda/gr.html

"Because the cosmological constant term is proportional
to the metric, the pressure associated with the vacuum
is then given by the relation":

pressure = -rho c2 = -mc^2/volume

"So the cosmological constant behaves gravitationally
like matter and energy except that it has negative
pressure. The net effect of a positive cosmological
constant is then to create a repulsive gravitational
force. This repulsion acts to expand the universe."

It would appear that the model:

F = M a = -Area rho c^2

M = Pioneer mass g

Area = Pioneer cross section cm^2

rho = space vacuum density ~ 6E-30 g/cc

c = speed of light cm/sec

is a direct measurement of the vacuum density by
Pioneer Space Craft.
