Of course they are compensating for the Theory of Gravity.
The Theory. Not necessarily the reality. Even though the mathematically compensatory mechanism of system x “works”, it does not follow that the Theory is accurate in whole or even in that particular part - if a part be of a whole.
Moon landings are workable from a geocentric math base for instance.
Speaking of, are you aware that you live in a geocentric universe? Or that the Planck Satellite CMB imaging has indicated so, twice, to the disdain of many an atheist professor and expert?
lol - or are you still insane?
