Speed limit for dark matter

  1. Dec 1, 2014 #1
    I have been wondering about how the universe created itself from nothing and it seems in spacetime, the time dimension must have come first followed by multidimensional space. Following this, matter and dark matter must have been created. While matter and dark matter both underwent timelike expansion, dark matter had the liberty to break physical laws and go through spacelike intervals. IF that is true, what is the speed limit and energy density limit for dark matter?

    It isn't. Dark matter follows timelike worldlines just like ordinary matter.

    I'd like to correct the misconception that the universe was created from nothing. Current theories regarding the origin of the universe are tentative guesses at best. Despite what you commonly hear or read, we have pretty much no idea if the universe even had a beginning or if it's existed for an infinite amount of time.
