LjSpike Posted October 4, 2015 Share Posted October 4, 2015 Hot Dark Matter is ultrarelativistic, so is near the speed of light. It would have a time dilation which would cause it to 'age' much slower than stationary objects. Could it be an extremely unstable set of sub-atomic particles then, but would just appear to be very stable to us because of the time dilation. Just a thought for you guys.
