So, I have been watching some science videos regarding Einstein's theory on general relativity and until today the predictions based on his equations have been proven to stand.
My question would be,: what happens in the scientific community if one experiment proves it wrong (not only Einstein, but even other laws and theories of physics).? Do we automatically get rid of these centuries-old theories, or do they get rewritten to fit the new experiment, or do they stay the same, but with exceptions?
