Physicists say universe evolution favored three and seven dimensions

Physicists who work with a concept called string theory envision our universe as an eerie place with at least nine spatial dimensions, six of them hidden from us, perhaps curled up in some way so they are undetectable. The big question is why we experience the universe in only three spatial dimensions instead of four, or six, or nine.

Don't know 'bout you but it seems to me that both my genes and my jeans have changed in both latitude and longitude 'thru the years.

Can an Electron be in Two Places at the Same Time?

Max Planck Researchers in Berlin show that for electrons from nitrogen molecules, the wave-particle character exists simultaneously.
In something akin to a double-slit experiment, scientists at the Fritz Haber Institute of the Max Planck Society, in co-operation with researchers from the California Institute of Technology in Pasadena, California, have shown for the first time that electrons have characteristics of both waves and particles at the same time and in virtually the push of a button can be switched back and forth between these states.

(Now, can somebody translate that into English?

Okay, here you go, though it seems to be a southern dialect of some sort...

Putting relativity to the test,

NASA's Gravity Probe B experiment is one step away from revealing if Einstein was right.
Almost 90 years after Einstein postulated his general theory of relativity—our current theory of gravity—scientists have finally finished collecting the data that will put this theory to an experimental test. For the past 17 months, NASA's Gravity Probe-B (GP-B) satellite has been orbiting the Earth using four ultra-precise gyroscopes, about a million times better than the finest navigational gyroscopes, to generate the data required for this unprecedented test. [...]

What goes up......must come down.

That dependeth on how fast it goes up...

On a collision course with discovery

Waltham, MA - In the universe of high-energy physics, the smallest building blocks of matter (or anti-matter) make the biggest news. Take subatomic particles, for instance. Colliding into each other at nearly the speed of light in the world’s highest-energy particle accelerator, protons and antiprotons produced some of the biggest physics news of the decade in 1995: the top quark.

The tenth anniversary of the discovery—it was the last unknown particle of the six-member quark family predicted by current scientific theory – is being celebrated by physicists around the world and at the Department of Energy’s Fermi National Accelerator Laboratory (Fermilab) in Batavia, Illinois, where the experiments took place inside the Tevatron, a four-mile long particle accelerator.

Physicists offer new approach to studying antimatter

What happens when two atoms, each made up of an electron and its antimatter counterpart, called the positron, collide with each other?

(Ka-BOOM!, of course, what'd they expect?

)

UC Riverside physicists are able to see for the first time in the laboratory that these atoms, which are called positronium atoms and are unstable by nature, become even more unstable after the collision.

(Unstable? Maybe if they got therapy?

)

Well....duh....and how much money did they waste to figure that out?
