But based on his wrong assumptions anyway.
Plese apply some scientific logics here. An unexplained force which needs another black force, isn´t something to set on equations and calculations because it´ll all end up in dark sentenses.
But you have to understand it dynamically and logically before you get into serious prediction troubles!
The logics says:
1) You have a force which assumingly works when lauching spacecrafts and satellites.
2) Your assumed force doesn´t work on the galactic scale.
3) You don´t have a universal force. Something is wrong and if keeping onto it will logically make lots of false assumptions and predictions,
the first evidential example = *dark matter*.
4) This
*force assumption* needs seriously revision and adjustment, and very likely have to be discarded.
The launching of spacecrafts and satellites can be done without implying Newtons idea in his *occult agency of gravity* just by calculating the escape velocity itself. You don´t have to mix Newton into this at all, and even the planetary orbital motions have been known long before Newton.
