Well, run for cover as the usual nuisance shows up to remind you how it feels to be cowards.

The British celebrate eccentricity as a type of intellectual brilliance ( JS Mill) but those foolish enough to follow them via the pseudoscience of astrophysics might believe in genius by association when it is simply eccentricity by association.

The Ra/Dec framework on which Sir Isaac hung his clockwork solar system in an amazing indulgence as it attempts to displace the Lat/Long and the 24 hour systems for the basic fact of planetary dimension, shape and rotation.

Inventing a 'flat Earther' to make yourselves feel better hardly is a compensation for be terrified of the fact that the Earth turns its 360 degree circumference in 24 hours.

RA was used long before Newton's time.

RA/DEC are not planetary coordinates, they are celestial coordinates. As such, neither "replaces" the other.

You should have been around over the years to know that trying to equate stellar circumpolar motion (RA/Dec) directly to daily rotation is not the smartest thing to do, in fact, trying to bypass the central Sun and the day/night cycle which anchors the Earth's rotation to noon is perhaps the dumbest mistake ever made.

The Lat/Long system and 24 hour system originate in the calendar system and its superlative framework where the proportion of rotations to orbital circuits is 365 1/4 rotations to 1 orbital circuit while the unfortunate RA/Dec modelers have their own thing going -

" It is a fact not generally known that,owing to the difference between solar and sidereal time,the Earth rotates upon its axis once more often than there are days in the year" NASA /Harvard

Fact indeed !, the higher reasoning faculties would normally accept the structure of timekeeping in close proximity to the daily and orbital cycles but unfortunately people are trapped inside a celestial sphere bubble and can't break free, even with the strongest effort.
