Why are physicists so quick to believe that dark energy and dark matter exist rather than rethinking general relativity? Isn't it a much smaller leap of faith to think that at the galactic scale and beyond, general relativity does not act the way we think it should or could be superceded by another theory of gravity (just like how Newtonian gravity worked to a certain extent but had to be rethought completely to explain more advanced phenomena)?
It seems ridiculous to me that many scientists think something like 95% of energy in the universe is something that we have never seen and potentially could never see rather than try to adjust a theory, which, granted has worked for 100 years, but needs adjusting, especially considering the fact that it bumps up against quantum physics as well.
