Strange Unexplained Cosmic Rays (ft PhD Comics)

I have a highly speculative explanation: it's failed big bang residu. In the invisible dark matter are constantly quantum glitches. Energized particles come into existance. But there have to enough particles together at the same time to make a new BIG BANG. As long as this treshold isn't reached the formed particles escape and hurl away at (almost) the speed of light.
See it as an attempt to get a grip on dark matter. To me dark matter is a mix of Newtonian eather and primordeal soup from which all living creation on earth stems. Have fun with it.
