Good bye Dark Matter, Hello General Relativity
dr. loser writes "The CERN newsletter reports that a new paper by scientists at the University of Victoria has demonstrated that one of the prime observational justifications for the existence of dark matter can be explained without any dark matter at all, by a proper use of general relativity! What does this imply for cosmology and particle physics, both of which have been worrying about other aspects of dark matter?"
Seems perfectly safe, since there is no dark matter.
.. that Dark Doesn't Matter??

The concept is neat. I'm not about to wade through the math and double-check anything. It'd be nice if we could stick with general relativity without dark matter.
On a side note, they are distributing the source. It's possible they may even be GPL friendly.
GPL friendly physicists rule.
fast as fast can be. you'll never catch me.
Geeze science, make up your mind - Think of the poor sci-fi writers for those made-for-tv movies! Have you considered THEM before publishing research findings??

Science just isn't definite these days, is it?
Maybe.

Aha, but the Electric Universe theory offers a solution as to why much dark matter is replacing the grey matter that used to be important to our society.
Was this another English to Metric conversion that screwed it all up?
TFA is just plain silly.
Every teccie knows that the universe is held together by gaffer tape, and the only problem has been to find the link between gaffer tape and dark matter.
If relativity does away with dark matter, well fine, but the cosmologists are missing the key issue here. All this means is that now we have to find the link between relativity and gaffer tape.

I knew that missing mass was my fat brother-in-law!

It means my physics paper is proper fucked, for one.

How many of us have done as much?
Hell, even Hawking has never shaken up the ideas of science and physics to anything near the degree Einstein has.
How long has he been dead? And he's STILL stirring up trouble!
Personally, I think his statue in Washington DC needs to be bigger. He's done far more for this country and the world at large than most of the people with bigger statues. It's just not fair!

As any engineer knows: every problem has a simple, easy to understand, wrong answer.

... but I do feel sorry for all the grad students who're crumpling up their dissertations papers.
Oh, no! This is going to ruin all those ST:NG plot devices.
My favorite quote on this general issue comes from Carl Sagan in one of the Cosmos shows:
Talking about early observations of Venus...
"Observation: Couldn't see a thing.
Conclusion: DINOSAURS!!!"
That scientific methodology has not left us, I am afraid to say.
there is no way that there is a smart Linux user for every dumb Windows user. You've never worked at a help desk have you?
"because QM is true and that's just the way it is.. "
I find this funny because I too see this a lot. It must come from trying to teach the subject. When pressed, however, I've had people fall back to "OK, it could all be wrong, but *you* have to proposed a better quantum theory of measurement first". So I think even Quantum(tm) alternatives may be considered seriously but critically, it's just that you have to propose a very broad replacement theory, beyond what could easily be expressed in English.
On the whole I too have found scientists very willing to consider alternative theories, as long as those theories haven't already been considered and determined to be false.

Based on the moderation that followed, I would say that "some people" don't like it when popular theories get questioned. Which just goes to show you--once a scientific "fact" has been established, our attachment to it becomes as dogmatic as any theological notion...
You're exactly right. This is also why our scientific ideas - like our theological ideas - haven't changed in thousands of years.
OK, not really. Just thoght it would be fun.
