Dark matter theory may be wrong

The idea that dark matter makes up most of the mass of the universe has been called in to question.
Studies of dwarf galaxies have revealed that their formation should not be possible if dark matter exists in the form that the most common theories suggest. Leading cosmologist Carlos Frenk described this inconvenient fact as "disturbing".
Scientists' predictions about the mysterious dark matter purported to make up most of the mass of the Universe may have to be revised. Research on dwarf galaxies suggests they cannot form in the way they do if dark matter exists in the form that the most common model requires it to.

Did anyone actually read the article? Because the headline is ridiculously misleading. It doesn't even suggest that dark matter is unlikely to exist. It says that cold dark matter probably does not exist and that we have no way to detect warm dark matter in the immediate future. Everything we have built to this point, including the LHC, was built under the assumption that cold dark matter was the dominant form in the universe so we don't have any specialized equipment yet that could detect warm dark matter.

I have been saying what this article is saying for years. It is foolish to assume that dark matter exists just because we can not fully understand how the universe holds itself together.

Just because I know in these forums it WILL need to be said again. The article does NOT say that dark matter doesn't exist, nor that it can't.

The headline of the article doesn't exactly outright say "Dark Matter is a LIE!!" either. It just says the theory 'may be wrong'.

The idea of dark matter,in my mind, is a load of nonsense to explain what the mathematicians are unable to work out . Yes better to think the univers out again.

Scientists looking to capture evidence of dark matter -- the invisible substance thought to constitute much of the universe -- may find a helpful tool in the recent work of researchers from Princeton University and New York University. The team unveiled in a report in the journal Physical Review Letters this month a ready-made method for detecting the collision of stars with an elusive type of black hole that is on the short list of objects believed to make up dark matter. Such a discovery could serve as observable proof of dark matter and provide a much deeper understanding of the universe's ... [More]

the article doesent state that dark matter doesent exist (learn to read my friends)but merely that there are indices that point in the opposite direction, and in this case one aspect of DM is less likely to exist or be prevalent in the universe.

1000 years ago, (western) scientists believed that the earth was the center of the universe. Today scientists look back and think about how silly that idea was. 1000 years from now, scientists will do the same thing. Assuming we survive for much longer, anyway. Science has more or less placed humanity on a course that I consider unsustainable. no scientist has ever claimed that the earth was flat. That was the produce of the theologist's, the superstitious and spiritualist people, who controlled that days knowledge.
