How? And it was now replaced with field. Hence he is wrong.
Should we say because Newton had the wrong idea and therefore he is not the one discover the gravity.
For maro-events his theory still is applicable and useful. As an approximation, it also has engineering merit by virtue of being simple.
Sure, you could say that, and it is said, and it is written quite often, but that statement would never be correct, not unless Aristotle (who had it wrong) and Galileo (who had it right) never existed.
If you want to insist that there is only one thing called "gravity" it gets kind of metaphysical, because nobody has ever totally understood it yet.
I mean, I'm fine with that, as one can define "gravity" as what makes the Earth go around the Sun, etc., but it's not dependent on specific humans, or any humans, ever existing.
If you do associate the concept with human theories, then I think you have to allow for it not being the same concept to all.
it's more like newton was 95% right, but einstein's successor theory was 99% right and covered some cases where newtons 95% right results were measurably wrong enough that it made an important difference. and we already know that einstein's theory has holes, we just don't know how to fix them
