I disagree slightly with that verbiage.

In my view, gravity (the phenomenon/natural law) is very real and has been defined/known for thousands of years. In its most simple form it is the statement, “what goes up, must come down”.

It is gravitation (the theory, and hypothetical gravity wave of which it is speculatively comprised, and presumed cause of the phenomenon/law of gravity), invented a few centuries ago, which doesn’t exist (outside of equation, anyway).
