Does Dark Matter exist?
« on: 24/07/2008 07:17:36 »
Does dark matter exist or is it just a fudge? Why propose an untestable element - this is a ridiculous proposal. A propsal in science must be disprovable.

So to claim that "dark matter" is there but so hard to test for is like saying there are ghosts lurking in out furniture and they only get visible when we are not looking

 
Mod edit - formatted the subject as a question.  Please try to do this to help keep the forum tidy and easy to navigate - thanks!

No, it's not the same thing. Such a claim on Ghosts cannot be tested, dark matter is, with its gravitational effects. Don't think that gravitational effects = presence of matter, that's false; to be a prove of presence of matter, these gravitational effects must reproduce those generated by the presence of matter distributed in a specific way.

So an excuse to protect an excuse

I don't but dark matter as it requires another illusion theory to support it - its a ghost

Note that I've never stated that dark matter exist, it's still a theory. There are many other theories about those gravitational anomalies, for example MOND (Modified Newtonian Dynamics), neutrines, cold stars, ecc ecc. That of dark matter is simply the better, at the moment, nothing else.

Can you suggest a better model which supports the observations, so far?

Looking at quasars from the early universe there is the phenomenon of gravity lensing which is supposedly caused by dark matter. This matter should be considered more as invisible than something like a dark cloud out there.

That is why we never see this illusive matter.
