Hold on, we have a problem here. The existence of "dark matter" was hypothesized as an explanation for observed phenomena. It isn't the only candidate hypothesis up for consideration (Modified Newtonian Dynamics [i.e. we got the math wrong]) is another). Experiments are under way to determine which -if any- hypothesis is correct
It isn't that we can't observe dark matter, we're observing *something*, we're just not certain what's causing it, and we're developing tests to find out.
Do we have any experiments to demonstrate spirits?
