Sometimes I think some of these articles are complete bullshit. Well, not the articles themselves, but whoever is giving them the information. Let me just make some guesses that no one can prove or disprove and dress it up to make it sound plausible. I mean maybe it's not, but you come up with an equation that seems elegant, then you run it through the tests and determine that ..... well we just don't have enough mass in the universe. Hmm. My equation can't be wrong, so..... there must be mass out there we can't account for. Let's call it dark matter.
