Reply to comment by InTheEndEntropyWins in Most cosmologists say dark matter must exist. So far, it’s nowhere to be found. Examining the philosophy of science behind two rival theories can explain why. by ADefiniteDescription

There's a standard model of particle physics, which the one you are referring to (and the original btw), and there's a standard model of cosmology called Lambda CDM. Being a particle physics guy I've only ever called it Lambda CDM.

And the especially relevant bit, for this topic, is the "CDM" part, where "CDM" stands for "cold dark matter".

("lambda" denotes a positive cosmological constant, i.e. "dark energy", so the standard model of cosmology = a hot big bang + dark energy + cold dark matter)
