John The expansion rate of space is accelerating from our point of red
shifting view in all directions from us. That gives us the feeling
we are at the center(this could not be reality) Astronomers seeing the
red shift getting redder and redder say it is accelerating faster and
faster. To accelerate continually needs a continual force.(like gravity)
That is another one of natures mysteries. I have one theory space goes
from concave to convex(Einstien would like that) or that matter,and
anti-matter are annihilating each other at a distance of 13 billion LY
from us. My last idea has continual (once a day) mini-bangs taking place
also very far from us is creating this space energy of accelerating
expansion. John take your pick. I'm laughing I just thought of another
way. Bert
