What do you consider "real" physics? Dark matter is not some voodoo word, it's part of the standard model of cosmology. While we know it exists, we don't know how it works, and theorizing & experimenting about it is crucial to understanding Nature.

Except for neutrinos dark matter is NOT part of the current standard model. There has never been a single measurement of a dark matter particle in the lab. E.g. LHCb specifically build to find SUSY particles, so far has found ZERO events. Also a very big amount of the "evidence" for Dark Matter can be parametrized with corrections to the Gravitational force. Since Gravity is the only force which not quantized yet changes are going to be made there anyway. E.g. It is very plausible that the MOND potential is a parametrized correction for quantum gravity effects.
