Welcome, Layah, to MOAB, where the future is past, the past is present, the present is future, and any other variation of that you can think of, including the concepts of near-past, far-future, and middle-present, except of course at speeds approaching or exceeding c, at which a whole new set of parameters takes over.

And I just thought that we always speak of approaching or exceeding the speed of light. What happens if we approach or exceed the speed of dark? Has the speed of dark been determined, and if so, what is it? If "d" = the speed of dark, does E=md^2 work? Does the speed of dark mean that all that energy is not expended by the conversion of mass, but is rather sucked up into the mass? Does the mass expand, or does it stay the same physical size but become massier? If the sucked-up energy produces less mass than the mass into which it is sucked, could that be considered as half-massed? There's a Nobel Prize in this, or at least something. Maybe something plastic and breakable.
