So does this require new physics to solve? What should the layman take away from this?
>distant galaxies have been speeding up in their recession, and the expansion rate, though still dropping, is not headed toward zero.
If the expansion rate is dropping, surely it is headed towards zero? Or are they using expansion rate to mean acceleration and the zero refers to the recession. Or am I misunderstanding something?
