Quote:The time to believe that some additional, unknown variable is influencing our science is when we have some indication that this is so. Without something detectable, what reason do we have to even suspect it?
Well, in this case, when it's being relied upon to confirm general relativity which is kind of important to our understanding of physics and the evolution of the universe. Also, astrophysicists are claiming "dark stuff" is going around us and through us all the time. They claim that "dark matter" has left "signs of passage" by bumping head on to the atomic nucleus of ordinary matter.
All of this I personally deem worthy of considering it a variable.
