Stands to reason.

That doesn't mean there's no Dark Matter in the cosmic cavities that you mention. I imagine there is. But the view at the moment is that most of it's in the same regions as most of the ordinary matter.

Also stands to reason.

But what I was looking for is has the so-called scientists accounted for the normal interstellar matter I referred to as normal mass of galaxies?

And another question...

I'm looking for information of how long it would take to get to light speed from a dead stop at various accelerations. For instance, at 2 G's how long would it take to get to c?
What? I've a drawing I want here. How I do that?
