Scientists Offer Proof of 'Dark Matter'

I don't get your poll, but I am very skeptical of dark matter, and rightly so. It is a misnomer to refer to the "theory of dark matter" because in a scientific context, a theory is supposed to be demonstrated correct under all circumstances. While the effects of dark matter might be well verified, the cause of those effects is not clear. I consider it "bad science" to think of an arbitrary cause, such as dark matter, or a modification to newton or einstein's laws and call that a new "theory" when it is REALLY just a hypothesis. If people were more consistent when it came to terminology there would be a lot less confusion on these things and a lot less distrust in science in general, because many people (and rightly so) have trouble distinguishing between TRUE theories and "popular theories."

22% of the universe is composed of dark matter.
