Surely Galileo’s concept of inertia was first? no? Ie an object in a state of motion possesses an “inertia” that causes it to remain in that state of motion unless an external force acts on it.
General relativity is a theory of gravitation that was developed by Albert Einstein between 1907 and 1915. According to general relativity, the observed
Gallileo’s concept was different from Newtons, dunno who had the idea first but that’s a different thing altogether.

linking to Ash, who knows a thing or two about Mass
The next Einstein, and Wheeler, need to think SMALL…
Was a great idea… til quantum mechanics.
Gravity isn’t a force, and Einstein was wrong – just still the best explanation we have at the moment.
Can it uncurve though? I guess you would need something with negative mass in order to flatten it back out again, no?
