Dark Matter: Invisible, Mysterious and Perhaps Nonexistent - By Robert Roy Britt Senior Science Writer 10 October 2005 Galaxies don't have enough regular matter to keep them from flying apart, scientists have been telling us for years. So there must be a bunch of unseen "dark matter" lurking in every galaxy. But dark matter has never been directly detected, and nobody knows what it might be made of. A few scientists remeain skeptical. To a lay person, it might sound downright crazy. Now a new study suggests there may be no such thing as dark matter. Fred Cooperstock of Northeastern...

Volume-holographic optical imaging instrument with the capability to return three-dimensional spatial as well as spectral information about semi-translucent microscopic objects in a single measurement is in use in different parts of the world for the last three years. The four-dimensional volume-holographic microscope is characterized theoretically and experimentally by use of fluorescent micro-spheres as objects. According to some scientists working under classified projects these special instruments are revealing secrets of the nature that can be totally bizarre to our knowledge of science and technology.

The genius of Albert Einstein, who added a "cosmological constant" to his equation for the expansion of the universe but later retracted it, may be vindicated by new research published today in the journal Astronomy and Astrophysics. The enigmatic "dark energy" that drives the acceleration of the Universe behaves just like Einstein's famed cosmological constant, according to the Supernova Legacy Survey (SNLS), an international team of researchers in France and Toronto and Victoria in Canada, collaborating with large telescope observers in Oxford, Caltech and Berkeley. Their observations reveal that the dark energy behaves like Einstein's cosmological constant to a precision...

Johns Hopkins University | 09 December 2005 | Staff
Clues revealed by the recently sharpened view of the Hubble Space Telescope have allowed astronomers to map the location of invisible "dark matter" in unprecedented detail in two very young galaxy clusters. A Johns Hopkins University-Space Telescope Science Institute team reports its findings in the December issue of Astrophysical Journal. (Other, less-detailed observations appeared in the January 2005 issue of that publication.) The team's results lend credence to the theory that the galaxies we can see form at the densest regions of "cosmic webs" of invisible dark matter, just as froth gathers on top of ocean waves, said study co-author...

Contrary to all expectations, the mysterious dark energy that is pushing the Universe apart may be changing with time. By observing distant, powerful bursts of gamma rays (gamma-rays), Brad Schaefer says he has preliminary evidence that the strength of dark energy is different today from when the Universe was very young. Schaefer, an astronomer at Louisiana State University in Baton Rouge, presented his results at an American Astronomical Society meeting in Washington DC. Just minutes after the data were presented in a late afternoon session, some astronomers were already calling the bold claim into question. An idea that arose in...

Dark matter warms up: Unseen mass more 'tepid' than thought.

Nature Magazine | 06 February 2006 | Mark Peplow
Astronomers have measured the temperature of dark matter for the first time. The discovery should help particle hunters to identify exactly what this mysterious substance is made of. Although dark matter cannot be seen, its existence can be inferred from its gravitational interaction with stars around it, which stops rapidly rotating galaxies from flying apart. Astronomers estimate that, on average, dark matter must be about six times more abundant than normal, visible matter in our Universe. But very little else is known about dark matter. "Even knowing it was dark was pretty profound," says Gerry Gilmore of Cambridge University, UK,...

It comes after 27 years of unbroken deficits which have totaled over 5 trillion dollars. Once the massive financing required to keep on paying for such a...

Physicists for decades have used "dark matter" as Spackle to fill pesky anomalies that seem to defy theories about gravity, the Big Bang and more. Recently, economists have proposed a similar fix for apparent anomalies in U.S. economic data. Unlike dark matter in space, dark matter in economics is a concept that has been mostly derided by other economists. If it's real, though, it might be no joke for investors. Harvard economists Ricardo Hausmann and Frederico Sturzenegger, [advance] a theory to explain something that has bugged economists and investors for years: A persistent trade deficit has built up a mountain...
