Pamela Fleming, spokesperson of The Institute for Basic Research, Palm Harbor, Florida, has released an open letter to the Directors of Cern laboratories in Geneva, Switzerland, containing unchallenged technical arguments showing that their ongoing test of the gravity of antimatter via alleged "anti-Hydrogen atoms" may be basically flawed, and requesting due scientific process on alternative more resolutory tests (http://www.i-b-r.org/G-Veneziano-denunciation.htm). New York,...

First Direct Evidence Of How Antimatter Interacts With Gravity
2013-04-30 10:11:53

John P. Millis, Ph.D. for redOrbit.com — Your Universe Online All fundamental matter in the Universe — protons, electrons, etc. — has counterparts known as antimatter. In most ways, antimatter simply mirrors regular matter. For instance, the antimatter counterpart to the electron is the positron, a particle of the same mass of the electron, but possessing the opposite charge and opposite spin. When normal matter encounters its antimatter counterpart, the pair will...

CERN Finds Matter-Antimatter Asymmetry
2013-04-24 14:40:18

Lee Rannals for redOrbit.com - Your Universe Online Scientists at CERN have submitted a paper to be published in the journal Physical Review Letters about the first observation of matter-antimatter asymmetry. The team said they made the observation while looking at the decay rate of particles known as B0s mesons. They now say that their findings indicate that antimatter decays at a faster rate than antimatter. Matter and antimatter are thought to have existed in equal amounts at the...

Antimatter Method Could Provide Major Experimental Advantage
2013-01-07 07:27:31

redOrbit Staff & Wire Reports - Your Universe Online By aiming a laser at antihydrogen atoms, researchers have found that they can force them to lose energy and plummet to temperatures 25-times colder than previously achieved -- a discovery which could greatly assist the study of the more elusive properties of antimatter. The method, which was developed by a team of experts from the US and Canada, is described in the most recent edition of the Journal of Physics B: Atomic, Molecular...

Microwaves Used In First Time Measurement Of Antimatter Atom
2012-03-08 05:43:30

An international team of physicists at CERN (the European Laboratory for Particle Physics) used microwaves to measure and manipulate an atom made of antimatter for the first time ever. While imprecise, the measurement represents an important first step in being able to study antimatter atoms in detail --  a critical part of understanding why the universe is made of matter and not antimatter. "This is the first time that anyone has ever interacted with an antimatter atom," said lead...

In a study published in the journal Nature Physics, researchers report trapping some 300 antihydrogen atoms for a record 16 minutes, a stunning technical feat that promises deeper insights into the mysteries of antimatter. Particles and anti-particles annihilate each other in a small flash of energy when they collide making the study of them extremely difficult. Fourteen-million years ago, at the moment of the big bang, matter and antimatter are believed to have existed in equal quantities....

Time-of-flight detector designed at Rice's Bonner Lab critical to antihelium observation Physicists at Rice University and their collaborators have detected the antimatter partner of the helium nucleus, antihelium-4. This newly observed particle is the heaviest antimatter particle ever detected. Scientists at Rice's Bonner Lab designed and built the new time-of-flight detector that identified antihelium-4. The $7.5 million detector was built by a U.S.-China collaboration led by Rice, with...

Berkeley Lab nuclear scientists join with their international colleagues in the latest record-breaking discovery at RHIC Eighteen examples of the heaviest antiparticle ever found, the nucleus of antihelium-4, have been made in the STAR experiment at RHIC, the Relativistic Heavy Ion Collider at the U.S. Department of Energy's Brookhaven National Laboratory. "The STAR experiment is uniquely capable of finding antihelium-4," says the STAR experiment's spokesperson, Nu Xu, of the Nuclear Science...

Once regarded as the stuff of science fiction, antimatter"”the mirror image of the ordinary matter in our observable universe"”is now the focus of laboratory studies around the world. While physicists routinely produce antimatter with radioisotopes and particle colliders, cooling these antiparticles and containing them for any length of time is another story. Once antimatter comes into contact with ordinary matter it "annihilates""”or disappears in a flash of gamma...

European scientists said on Monday that the creation and capture of anti-hydrogen atoms has put them on track to solving one of the greatest cosmic mysteries. Anti-matter is of intense interest outside the global scientific community because it has often been thought of as a potential source of boundless and almost cost-free energy. The announcement from the European Organization for Nuclear Research (CERN) came just three weeks after another of the three teams at the particle research...
