Hi Jorrie,

Sorry to see you have lost a GA. You must have made somebody mad. I think I got 2 of mine by making somebody mad! I'm confused again/still. You told Roger that I described it right in 13 where I said "Both forces are presumed to have always been there." Now:

"When Lambda stopped blowing air into the balloon (after inflation), the surface coasted outwards kinematically, with the surface energy causing a deceleration due to mutual gravitational pull. It hence appears as if all galaxies drift apart on the large scale. Today Lambda is again blowing into the balloon, we think..."

I think inflation was something separate from Lambda. In any case this makes it look like an in-continuity. Furthermore, I will restate what Jon said in different words (but possibly a different meaning than he intended): Are you suggesting that empty space (which has no mass) has momentum?

Your reference to "at last scattering" is the point in time when the universe changed from opaque to transparent?

In the reference to LCDM(0.3,0.7), the 0.7 is Lambda? A (0,0) universe is one without a cosmological constant?

Consider a balloon partially blown up. Two buttons are glued to it. A string is tied between the buttons (the tether). Now the balloon is blown up some more, The tether is taut. When the tether is cut, the buttons fly apart, not come together, not so?
