You cannot discuss or comprehend the concept of the cumulative
effect of drag because we're not using a TERM, a label you've
attached to the concept? Drag is singular and cannot be
cumulative? Hahahahah! We must say "force of
deceleration" rather than "cumulative effect of
drag"? This is science? These are thinking human beings?
Where it would seem that the discussion has stopped because of a label or term, in fact this is just the EXCUSE. They are fussing like this BECAUSE THEY CAN'T DEAL WITH THE PROBLEM PRESENTED. When boggled, digress. Simple as that.
The problem, again, dear dead-head lads, is this:
If a planet is continuing in a steady orbit, without any
impetus such as the propulsion humans find necessary to keep
their probes and satellites from drifting off the path they are
set upon, then something is either steadily pulling or pushing
the planet to maintain its orbit in the face of all other
influences. The influence of the orbiting planets upon each other
would otherwise, over time, alter the orbits dramatically. Why
would they not? Each time a given planet lined up with the
massive Jupiter, and was perturbed to speed up or slow down due
to this influence, unless there were another influence this
perturbed planet would remain in motion a bit slower or faster,
perpetually.
