Yes, but the point is nobody is assuming they are perfect. Rather, the possibility is that either General Relativity is wrong or there is Dark (i.e. non-photon emitting) Matter. When this was investigated via observation (i.e. not assuming, but checking), the observational evidence seems to...

Do you happen to know the name of this equation? Okay, so first of all, you seem to be under the impression that it was by measuring the weight of the entire universe that we came to conclude that Dark Matter existed. It's much simpler. We just take the Milky Way and we can see that under the...

Dark Matter isn't as such created to "complete an equation". Rather there already is a complete equation, the General Relativistic Field Equations. The problem is that it only predicts the correct rotational speed of galaxies if one assumes a large amount of undetected matter. So either there...
