From: Yousuf Khan on 9 Jun 2010 14:05 Or how about the most obvious answer? Dark Matter comes in no types, it doesn't exist. These two scientists are just trying to find new ways to justify a failed theory. There is already quite convincing alternative explanations for the PAMELA positron detections, namely that it's produced by supernovas. Not just any supernovas, but a very specific type of supernova recently discovered, one that produces Calcium and Titanium. And searching for WIMPs in isolated mines is a waste of time, as they could easily be signals for neutrinos or just radiation within the mine itself. Yousuf Khan *** Does dark matter come in two types? - physicsworld.com "That isn't the only problem. If the PAMELA signal was indeed evidence for annihilation, the dark matter involved would be of a type that would never show up in direct-detection experiments, such as CDMS-II, located in a mine in Minnesota, US. But in recent years CDMS-II and other direct detection experiments have found their own hints of dark matter. " http://physicsworld.com/cws/article/news/42872

And it seems to me, the basis of DM lies in applying a M/L ratio determined in an area that is "swept clear" to an entire spiral galaxy... *despite* "seeing" evidence of anomalous normal non-lumenous matter collections that are not present near the center. DM is perhaps simply justifying a simple accounting error. Now what happens to cosmology if we have "nine" times more normal matter? > There is already quite convincing alternative > explanations for the PAMELA positron detections, > namely that it's produced by supernovas.

I also noticed that particle detections (other detectors) were aligned with our motion through the Milky Way, rather than aligned radially outwards from Sagittarius-A, or orthonormal to both. > And searching for WIMPs in isolated mines is a > waste of time, as they could easily be signals for > neutrinos or just radiation within the mine itself. Not a waste then, since they also can serve to detect supernovae events. Besides, those holes have to be good for something... ;>) David A. Smith

If only scientists considered the obvious as carefully as you. Wait, they have. There's a reason shielding is discussed so heavily in these types of experiments. > > Yousuf Khan > > *** > Does dark matter come in two types? - physicsworld.com > "That isn't the only problem.

"http://physicsworld.com/cws/article/news/42872 The gravity accelerator of satellites moving in gravitational wells accelerates axle forces, slower speeds carry hidden inertia (galaxy torque). This torque can be shown in models "as if more weight was riding on the axle" But this theory ran into confusion when scientists said that the shape of dark matter is not disk bound, but is like a ball, a squished ball around galaxies. Then I said that most of the matter is not on the disk where things are highly compacted with gasses and matter, but in the less active dark zone, which too revolves around an axle running vertically through the galaxy's center. It makes sense, since smaller galaxies have more dark matter, and larger ones attract more of the mass to the disk region. The gravitational sphere of a spiral galaxy rotates even in the dark region. Galaxies in the early universe had dark matter between them, then galaxies ripped apart into chunks, where dark matter was trapped around them. These chunks concentrate around galaxies gravitationally, and a weaker dark matter is seen around galactic clusters, but there dark matter forms a long cigar shape.
