“Dark matter is a necessary add-on to the wrong idea that gravity and not electromag forces mainly bind the cosmos together.”

And not understanding that gravity is a component of electromagnetic forces.

Matter of fact, just about everything is a matter of electromagnetic forces.

Can there be property rights in dark matter?

The fudge factor needed to save Einstein gravity...

One of many, actually. When you need to posit an entire scalar field to save the observations, the theory that predicted a zero field everywhere is wrong.

"There’s no such thing as “dark matter.”"

Hmmm. I found this article that says it does exist.

"A universe that's dominated by dark stuff seems preposterous, so we wanted to test whether there were any basic flaws in our thinking," said Doug Clowe of the University of Arizona at Tucson, leader of the research team. "These results are direct proof that dark matter exists.................Sean Carroll, a cosmologist at the University of Chicago who was not involved with the study. "No matter what you do [in devising new theories] you're going to have to believe in dark matter," he said.

Except the strong, weak, and uh... gravity forces.

Please give us your unification details, and win the Nobel Prize in Physics in the process.

Why isn’t this a pattern of light sources?

If I photograph a hand full of dirt thrown in the air, do I call the picture a pattern of the surrounding air?

Hmmm from MSNBC. Why should I believe it?

The article has the usual lamestream media gee-whiz take on a lot of science -- reporting speculation and the observing scientists' opinions as facts.

For example the caption for the picture, "Other telescopes were used to detect the bulk of the matter in the clusters, which turns out to be dark matter (highlighted in blue)." Should more accurately read, "Other telescopes were used to generate the blue highlighted area based on hypotheses of how matter affects light passing through it."

Note that there is no evidence that the blue highlighted matter is any different than ordinary matter except that it has, apparently moved away from the site of the event more quickly than the matter revealed by X-ray emission.

The claim that "The hot gas — normal matter — was slowed by a drag force described as the cosmic equivalent of air resistance. But the dark matter was not slowed by this effect, presumably because it does not interact with normal matter, as theory had predicted." Assumes that the matter highlighted in blue also experienced the drag force. Perhaps it is matter that was ejected without passing through the area creating the "drag force" thereby not being slowed nor heated so as to emit X-rays.

So how do they know it is not just bent space?

Current accepted theories equate "bent space" to mass. You can't have one without the other.

If you can have "bent space" without mass then some entirely new theory about how space comes to be "bent" must be devised. A much more difficult theory to derive than speculations about the nature of this, so called, "dark matter" and "dark energy".

Consider that most of modern day cosmological evidence and most sub-atomic evidence comes from smudges and streaks on photographic plates or electronic emissions from detectors whose sensitivity is such that they are subject to random readings.

But, somehow, the observations seem to be reproducible and consistent with proposed theories.

If this stuff was 95% of the universe as claimed, you’d be vacuuming it off your carpets four or five times a day. The entire theory is munged.

Why does the phrase “troops in the open” come to mind when I look at that picture?

"These results are direct proof that dark matter exists."

Nope. Even if true (which they aren't), the results would have been *indirect* inferences that dark matter exists...a far cry from direct proof.

No matter. Dark matter doesn't exist, except as a mathematical construct.

If the deed can be recorded, which presupposes state-registered surveyors following accepted procedure and the willingness of clerks in the Recorders Office to make an entry in their books.

Very well, professor .... something is causing the phenomena observed. What do you think is doing it?

Well, the correct answer is that we don’t know.
Could be curved space.
Could be data misinterpretation.
Might be some unknown force.
Might be some unknown effect.
Might be that our model of space/time is incorrect.
