Actually, we are not CERTAIN that dark matter is truly there. It's on the edge of being confirmed as a real, true entity. Some people even consider it a topic of fringe science, which deals with controversial topics of science, which most people consider fiction. Topics like pyrokenesis, bilocation, time travel, alternate universes, teleportation, and all that neat stuff.
