When was gravity settled science?

Gravity saw a heavy modification within the last 20 years with the discovery of the accelerating expansion of the Universe (dark energy forces).

You're confusing the notion of "settled science" with "the end of knowledge".

The changes in our understanding of gravitation that have occurred in our generation do not make it advisable for you to walk off the edge of a building. That's what is meant by settled science.
