Dark matter is a central but contentious part of the dominant model of cosmology. It has never been observed directly and is seen as an arbitrary add-on to Einstein’s theory of gravity, just to make the data fit. MOND has for a long time been considered the most credible alternative theory of gravity, doing away with the need to postulate dark matter. But a recent study lead by Dr Indranil Banik, a past supporter of MOND, demonstrates that the theory is in fact wrong. The search for a more credible alternative continues. According to the dominant paradigm in cosmology, the majority of the stuff that makes up our universe is not the ordinary matter we see around us, but something called dark matter.
