Observations of objects floating upwards without any external force. Consistent measurements showing that the gravitational constant varies significantly on Earth.

Answer 1

To contradict the theory of gravity before it was proven to be a law, the most compelling evidence would be observations of objects floating upwards without any external force. This would directly challenge the fundamental concept of gravity, which states that masses attract each other, and would imply that the forces acting on those objects are in opposition to gravitational pull, thus providing significant evidence against the validity of gravity as a universal force.
