> But now it’s time to consider... Almost invariably when an article title says "it is now time to..." there has been no actual threshold that has been crossed making "now" special at all. The growing types of evidence for a "dark matter" effect on large scales, vs. the absence of any small scale evidence for it, has consistently begged for new particle, gravitational, and other types of theory to be explored. It is a strange situation to have something appear so consistent with one of our pillars (general relativity), while completely absent from the other (quantum mechanics). I am crossing my fingers that any successful understanding of dark matter on the small scale might shed light on how those two pillars could be combined into a single theory. But any explanation will be most interesting!
