Yes E^2 = energy/volume = pressure
but what E?

Uncertainties


Solar radiation pressure at many AU:


..03 (+/- .01) x 10^-8 cm/sec^2


is insignificant to observed deceleration of:


8.74 (+/- 1.33) x 10^-8 cm/sec^2


Actual pressure on Pioneer space craft in more in line
with vacuum energy


rho c^2


where


rho = ~6 x 10^-30 g/cm^2


corresponding to estimate of dark energy_matter density
