No, this is showing a counterexample, which would render the original theory moot. If we find a planet tomorrow that pushes you away rather than attracting you, then Newton’s theory of gravitation is (probably) no longer a valid model of the real world, or would have to be revised. That is just how science works.
Such a remarkable achievement! We should put capitalists on the Starship ASAP so they can enjoy the fruits of “their” labor!
