Unless new evidence or information is found, then the model may or may not still be valid and if not, then your law is disproved and your peer reviewed work is file thirteened.
The simple nature of a body of knowledge, aka, “science”.
Newton’s proved that gravity is a force. Then Einstein proved that gravity is a space/time field. Did Einstein’s model disprove Newton’s model? Absolutely not. Newton’s formulas are calculous, and are still used heavily. Newton’s and Einstein’s models are both 100% correct. They just describe gravity in separate terms.
When, not if, someone completely defines gravity in terms of super symmetry and/or quantum mechanics then that model will also be correct. I suspect that model will incorporate dark energy.
