Several hundred years ago, we thought that the Earth was flat. Turns out, the Earth is round. We also thought that the Earth was the center of the universe and all the stars rotated around us. Then came Gallileo and peed in the Pope's wheaties. The science wasn't nearly as settled as we thought.
When I was in high school, I was taught that nothing can travel faster than the speed of light. Einstein said so. The science was settled. Then, along comes CERN last week and says it has measured particles that move faster than the speed of light. Hmmm. Isn't that interesting? It seems that science is never settled, after all. As we learn, we learn new things. As we learn new things, the old things are either supported or repudiated. It's science, not religion.
When the weather weeneis tell you that the science is settled, remember Einstein, CERN, Gallileo and all the other real scientists.
