« The
model also predicts a ratio of dark matter to ordinary matter that agrees with
the value obtained by NASA's WMAP satellite in 2003. It does, however, assume
the existence of an "alternative vacuum" that has the same energy density -- or "cosmological
constant" -- as our own ordinary vacuum.”
Article at: http://physicsweb.org/articles/news/9/12/4/1
« According to the new model, one sixth of the nucleons were freed this
way, entering the ordinary vacuum and becoming normal matter. The rest of the nucleons remained trapped
as dark matter inside the balls of the alternative vacuum. »
“At
sufficiently high temperatures and densities, they could have started consuming
the star, so releasing enough energy to make it explode in a supernova.”

SCIENTIST SAYS NEUTRON STARS, NOT BLACK HOLES, AT CENTER OF GALAXIES, December 01
For the past 50 years, black holes have been all the rage. Now, a University of Missouri-Rolla researcher says they never existed.

CHANDRA PROVES BLACK HOLE INFLUENCE IS FAR REACHING, December 01
Scientists using NASA's Chandra X-ray Observatory have discovered evidence of energetic plumes - particles that extend 300,000 light years into a massive cluster of galaxies. The plumes are due to explosive venting from the vicinity of a supermassive black hole, and they provide dramatic new evidence of the influence a black hole can have over intergalactic distances.

THE TOP PHYSICS STORIES FOR 2005 (Score: 1)

THE TOP PHYSICS STORIES FOR 2005. At the Relativistic Heavy Ion Collider (RHIC) on Long Island, the four large detector groups agreed, for the first time, on a consensus interpretation of several year's worth of high-energy ion collisions: the fireball made in these collisions---a sort of stand-in for the primordial universe only a few microseconds after the big bang---was not a gas of weakly interacting quarks and gluons as earlier expected, but something more like a liquid of strongly interacting quarks and gluons (www.aip.org/pnu/2005/split/728-1.html ). Other top physics stories for 2005 include, in general chronological order of their appearance throughout the year, the following: the arrival of the Cassini spacecraft at Saturn and the successful landing of the Huygens probe on the moon Titan (http://www.aip.org/pnu/2005/split/716-1.html ); the development of lasing in silicon (Nature, 17 February); the biggest burst of light ever recorded from outside the solar system, from a soft gamma repeater (http://www.aip.org/pnu/2005/split/721-1.html ); further evidence for superfluid behavior in a solid (http://www.aip.org/pnu/2005/split/724-2.html ); detection of infrared radiation directly from an exoplanet (http://www.aip.org/pnu/2005/split/724-1.html ); zeptogram mass sensitivity in a cantilever sensor (http://www.aip.org/pnu/2005/split/725-1.html ); spashless impact of droplets at low pressures (http://www.aip.org/pnu/2005/split/725-3.html ); the demonstration of pyrofusion, fusion reactions created with a pyroelectric crystal (http://www.aip.org/pnu/2005/split/729-1.html ); the best yet prediction of hadron masses using lattice QCD (http://www.aip.org/pnu/2005/split/731-1.html ); the best measurement yet of the weak nuclear force (http://www.aip.org/pnu/2005/split/736-1.html ); superfluidity directly observed in a sample of ultracold fermi atoms (http://www.aip.org/pnu/2005/split/734-1.html ); extension of the "comb" technique for measuring frequency (a topic pertaining to the 2005 Nobel prize in physics) into the ultraviolet (http://www.aip.org/pnu/2005/split/735-2.html ); geoneutrinos observed (http://www.aip.org/pnu/2005/split/739-3.html ); hybrid atom-molecule dark states (http://www.aip.org/pnu/2005/split/744-1.html ); using statistical mechanics to predict the effectiveness of flu vaccines (http://www.aip.org/pnu/2005/split/724-3.html ); hydrophobic water (http://www.aip.org/pnu/2005/split/747-2.html ); 2005 Nobel Prize (http://www.aip.org/pnu/2005/split/748-1.html ); molecules that walk (http://www.aip.org/pnu/2005/split/751-2.html ); phonon Hall effect (http://www.aip.org/pnu/2005/split/750-1.html ); short gamma ray bursts identified as coming from in-spiraling neutron stars (Nature 6 October); hyperentangled states (http://www.aip.org/pnu/2005/split/754-1.html ); further progress in research concerning left-handed or negative-refraction materials, including perfect lensing (Science 22 April), almost perfect lensing in the mid-infrared (http://www.aip.org/pnu/2005/split/750-3.html ), and extension of negative-index behavior into the near-infrared region (http://www.aip.org/pnu/2005/split/756-1.html).

(User Info | Send a Message) http://www.suppressedscience.net | This story about dark-matter balls omits important information. It states
Dark matter was originally proposed to explain why galaxies rotate much
faster than can be explained by the amount of visible matter they
contain.
whereas the correct statement should be
Dark matter was originally proposed to explain why galaxies rotate much
faster than Newton's Theory of Gravity can explain using the amount of visible matter they
contain.
The success of MOND (modified Newtonian mechanics) shows that there
may well is no dark matter whatsoever, and that Newton's law of
gravity may simply be incorrect.
Reg Cahil's Process Physics also proposes that the solution to the dark matter mystery lies in a modified law of gravity.

(User Info | Send a Message) | What a pile of crap! "Exploding dark-matter balls predicted"
I'm no eggspert, but these outlandish theories of dark-matter and all-that-jazz is making physicists look stupid. I can see the healdines now "Exploding balls in a different vacumm: Hoover and Dyson issue Global product recall!"
Get real.

ASTRONOMERS MAP DARK MATTER IN STARTLING DETAIL (Score: 1)

(User Info | Send a Message) http://www.zpenergy.com | ASTRONOMERS MAP DARK MATTER IN STARTLING DETAIL, December 09
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.
