SILICON VALLEY, Calif., Aug. 17, 2010 (AScribe Newswire) — The Astro2010 Survey Committee report, “New Worlds, New Horizons in Astronomy and Astrophysics,” was released by the National Academies in Washington, D.C., on Friday, August 13. The report recommended priorities for the most important scientific and technical activities for astronomy and astrophysics over the next 10 years.
One of the three principal recommendation sections is about the “physics of the universe,” which focuses on discovering the nature of dark matter and the physics of “dark energy,” which is responsible for the accelerating expansion of the universe. This dark matter/dark energy portion of the report appears to be at least seven years behind what is known or believed by some of Earth’s leading cosmologists. This newswire was written to bring this multi-billion-dollar state-of-knowledge problem, involving the recommended Astro2010 priorities, to the attention of NASA, the National Science Foundation (NSF), the U.S. Department of Energy (DOE) and the world’s cosmologists, astronomers and astrophysicists.

SILICON VALLEY, Calif., Aug. 4, 2010 (AScribe Newswire) — Astronomers studying the tiny Milky Way satellite galaxy Segue 1 have concluded it has the highest measured dark matter density of any known galaxy. Therefore, it should be a prime testing ground for dark matter physics and galaxy formation on small scales. Their July 27 online scientific paper entitled, “A Complete Spectroscopic Survey Of The Milky Way Satellite Segue 1: The Darkest Galaxy,” is posted at arXiv.org.
Their paper indicates that as a next step, the astronomers plan to study gamma rays being emitted from Segue 1 resulting from collisions and thereby annihilations of WIMP (Weakly Interacting Massive Particles) pairs. Apparently, the paper’s authors believe that if they observe gamma rays emanating from Segue 1, their source would be putative cold dark matter nonbaryonic supersymmetric WIMPs being annihilated in pairs.

SILICON VALLEY, Calif., July 14, 2010 (AScribe Newswire) — Oxford University researchers have discovered a plausible form of dark matter that is a solution to what is called the “solar composition problem.” Surprisingly, it is compatible with Jerome Drexler’s relativistic-baryon dark matter announced in 2003. The observed rapid heat flow from the center of the Sun to its surface has been unexplainable until the Oxford researchers posited that the Sun whizzing around the galaxy for 5 billion of years may have collected large quantities of dark matter, thereby altering the Sun’s heat-flow parameters.
The next step for the researchers Subir Sarkar and Mads Frandsen was to determine the specific form of dark matter necessary to achieve the observed heat flows in the Sun. They were forced to rule out the “usual candidates for cold dark matter (CDM) such as supersymmetric neutralinos [also called WIMPs] which have a relic thermal abundance determined by ‘freeze-out’ from chemical equilibrium.” Read More »
SILICON VALLEY, Calif., July 8, 2010 (AScribe Newswire) — Albert Einstein once said, “To raise new questions, new possibilities, to regard old problems from a new angle, requires creative imagination and marks real advance in science.” These three approaches also were used in the four-book cosmology series discussed here.
Jerome Drexler’s four-book postmodern-dark-matter-cosmology course for astronomers, physicists, applied physicists and plasma engineers is now ready for use. It utilizes an astronomical-case-study teaching method, which should lead to the solving of twenty cosmologic mysteries and an accelerating rate of new astronomical discoveries. Read More »
