Dark matter, as we know, constitutes more than 80% of the mass of the universe, but it is surprisingly difficult to detect — apart from gravitational effects. apparently it is silent, elusive and unseen.
You might notice that these are are the same qualities that ninjas traditionally possess.
, we can only conclude that dark matter is made of ninjas, lurking around in every corner of outer space and swooping down on Earth (or other planets) in some rare occasions.
As an aside, this easily answers Professors Foglio's Universal Ninja Puzzle.
