I'm by no means a astrophysicists but I love reading, talking and studying all I can on the subject. I have a question on the original formation of dark matter. Could it be plausible that the formation of dark matter be the end result of the antimatter/matter collision right after the Big Bang? Could it be the remnants of that explosion, seeing that supermassive stars collapse into black holes and smaller a stars produce massive nebulas could this explosive have produced something far stranger such as dark matter. Please correct me if I'm wrong but don't both antimatter and dark matter produce gamma rays as well as neutrinos. Are there any theories on this or is it not plausible?
