Because everything in the universe has a definite volume. everything with a volume must have a mass. mass is the amount of "stuff" in a given volume. so if you were to weigh even the smallest particle it would have a weight most likely measured in amu ( Atomic Mass unit). everything has a weight because everything has gravity. whether by centripital force, atmospheric pressure, or any type of atomic bond.
