"outer edges" of the known universe. Not outer edges of infinity.
"The acceleration is drawn from mapping movement of younger galaxies, not by tracking changes for any one thing. The latter requires far more time than is practical." May it be impractical, but the currently used data yields inconclusive results.
That's my entire point. That unequal acceleration may happen now, but it is also possible it is not happening now but happened for a limited time in the past. The currently available data supports both theories.
I don't want to go farther with this. You, Noax, keep proving that speeds are different. I have already accepted that. You keep proving relentlessly, mercilessly and ceaselessly, that more distant something is from here, the faster it moves away from us. This I accept as well, so no need to labour the point. The only thing, the ONLY thing I am after is what tells us that the acceleration is happening now, currently, opposed to the unequal acceleration having occurred any time in the past.
All we know is speed. And that speed increases with the distance away from us -- linearly or quadratically, does not matter. It tells us unequal acceleration has occurred but it does not tell us conclusively whether the unequal acceleration occurs now or occurred in the past. Yet that is what I'm after, to know that, to nail that down.
