Thanks Grav. I visited your website and tried to email you from there. My anti-virus software alerted me to a trojan horse; just thought I would let you know. I also followed your topic on PhysOrg forums.

There are some interesting aspects to the neutrino pressure concept.

The motion and forces that are at work cause what we observe so if we can't explain what we observe, we don't understand the physics yet. Your concept could very well explain some of the observations, and if so, could add “physics" to the concepts of dark matter, dark energy, and vacuum energy. Is that a fair statement of am I in left field?

I have been comfortable with the concept of vacuum energy density (VED) (cosmological constant) in imagining the nature of the universe, but have not yet found anyone knowledgeable who can educate me on VED.

It seems to me that VED and neutrino pressure would serve the same function, i.e. define/explain the movement of objects in space. The curvature (warping) of space around an object with mass and momentum is the general relativistic representation of VED and of neutrino pressures, if I am on the right track. What can you tell me to help me along here?
