time-blog.com — "Last summer, astronomers used a really clever observing strategy to present the best evidence to date that dark matter, once dismissed as a hare-brained idea, really does make up most of the mass of the universe. The image above does it again, in a slightly different way."

@l0neNot always is not the same as never. To disprove "always" all you have to do is find one example where it doesn't happen.!(Aa) = E(!a)A is for everyE is there existsLearn some philosophy

You know, all this talk about "scientific facts" and "proof" is disheartening. It all comes from being taught wrong in school (Sugarcoating knowledge -- remember when 2 - 5 was an impossible operation?) and popular misunderstanding and misuse of the terms (A steep learning curve is bad, right? Think again.).In science, nothing is "proved" or "disproved", only supported or not by evidence. Also, a fact is and remains a fact until the point where evidence contradicts it. Then the process starts again. It's no big deal.If you're going to wait for "proof" for things to reach "fact" status before accepting and working on them, you're in for a very incomplete life.

@XarouIf you read the post you are commented on more carefully it was a question not a statement. Your comment does not address his question.

@Xarou: Your analogy is a bit condescending. A better version might go like this:Animal A is brownAnimal B is bear named BoboAnimal A = Animal B@triskaid: Years ago that was my first impression with reguards to dark matter & dark energy. I figured it was a little egotistical to say you know the size of the universe and how much stuff is in it. It's tough to say from where I'm sitting, though. I'm willing to give them the benefit of the doubt. I'm guessing their numbers aren't coming from some dude in a telescope saying, "ok, planet # 54,681... check! How big is that one? Ok, let's look over there; get out your voltometer!" :)
