The big physics-y news story of the moment is the trapping of antihydrogen   The big physics-y news story of the moment is the trapping of antihydrogen

Antimatter was first predicted1 in 1931, by Dirac. Ever since then there has been 100s of Science Fiction books and Movies made with this concept at its heart. StarTrek Enterprise Engine run with Antimatter. In reality the work with high-energy antiparticles is now commonplace, and anti-electrons are used regularly in the medical technique of positron emission tomography scanning. Antihydrogen, the bound state of an antiproton and a positron, has been produced2, 3 at low energies at CERN (the European Organization for Nuclear Research) since 2002. Antihydrogen is of interest for use in a precision test of nature’s fundamental symmetries.

A clearer understanding of the Universe, its origins and maybe even its destiny is a significant step closer, thanks to new research. As part of a major international experiment called ALPHA, based at CERN in Switzerland, researchers have helped to achieve trapping and holding atoms of 'anti-hydrogen', which has not previously been possible.

ALPHA has therefore developed techniques that not only cool and slow down the anti-particles that make up anti-hydrogen and gently mix them to produce anti-hydrogen atoms, but also trap some of the anti-atoms for long enough so they can be studied.

This breakthrough will make it possible to study 'anti-matter' closely for the first time, and so develop unprecedented insight into its composition/structure and improve understanding of the fundamental physical principles that underpin the Universe and the way it works.

The initiative is expected to run for several years, with ALPHA commencing tests on anti-hydrogen atoms in around five years time. My only worry is when the size of these Antimatter goes larger. Next would be Ani- Helium and later bigger Anti-Atoms. This is really unknown territories.

There is a great QA on the subject here.

About Scifiwood News Reviews and Blogs
These are various short and long News Articles, Reviews and Blogs by Salar Golestanian and employees of SalarO.com as well as contributors of Scifiwood.com. The subject matter are mixed topics with Pure Science to Science Fiction as well as general topics on Web Trends, Technology, Software Engineering genre, or whatever subject that can affect the convergence of today's technology with Science Fiction in any shape or form.  These Blogs and Reviews don't have commercial or corporate aspiration, so they are indeed completely independent views. Some of these entries may be short and just link you to the actual news or site that can expand further on the subject of interest.  In Phase II we plan to incorporate some Social Networking applications within the portal.
