Well, this we don't know. We actually do not even know whether there are dark matter in the universe. It is for the moment only hypothetical. But this is an hypothesis that works extremely well :)
a hypothesis must be proven by research, and then to know that we must use what approach. and also want to examine what there is dark mesteri? and I in this case I will search for the concept of alqu'an about the dark mystery first
