think again. scientific models change all the time. Dalton's atomic model worked well enough, but Thomson created a better model with better tools, then Rutherford created a better model with better tools, and the atomic model continues to evolve.

The one thing that a scientific model has to do is predict the results of an experiment you haven't done yet.
