but, if you picture really strong movement in the the curved space membrane, great centrifugal,* ACCELERATING expansion would result pulling away increasingly from the source point.
Science news claims the universal expansion IS accelerating, I doubt it. How would you know , if it can not be dedected locally and we see only the past.
may be it is a trend?
* cofty might be interested that this movement along a curved path, is the 4st theory why wings generate lift.
The airflow has a curved path, and the resulting flow has an upward, lifting, centrifugal effect.
