Universal Extra Dimensions: New DZERO Results

Of the dozens of new physics models which are currently on the market of Standard Model extensions and plug-ins, the ones hypothesizing the existence of additional dimensions of space-time beyond the 3+1 we know about are definitely among the most fascinat ...

Dark energy- Accelerating expansion of distant galaxy due to negative mass-1

I had a new computer simulation. We set up each model from the birth of universe to the present, and calculated GPE using computer simulation in each level. As a result, we could verify that “pair creation model of negative mass and positive mass” explains ...

A Tour of the Private Pop Science Art Collection

The   6 minute YouTube video, available in high def, provides a walking tour of my private Pop Science art collection. One painting spent a summer month in Lancaster, PA as part of a juried show. "Turquoise Einstein" was a hit with the public, b ...

Virtual Particles Real Yet Real Ones Unreal According To Feynman

Often when reading about cutting edge physics and the amazing feats of the Large Hadron Collider, we are treated to crazy scenarios involving “ virtual particles ”, also variously referred to as “ghost particles” or worse. These labels clearly distinguish ...

A Strange Question On Cosmic Microwave Background Radiation.

I just ask. If I look at a glowing something with an antenna, I will not get any signal, I think. This is, I believe, because the radiation comes as photons, more or less, because it is a result of thermal motion. Each of the myriads of electrons in the g ...

2012 Wolf Prize In Physics

Those working on quantum gravity have to accept the fact they are unlikely to ever compete for a Nobel in physics. No matter how brilliant and how widely accepted the contribution, a Nobel prize in physics is not awarded as long as the work has not been ve ...

No New Heavy Quarks In ATLAS

A nice new search for heavy quarks has been completed by the ATLAS collaboration in 7 TeV proton-proton collisions data collected in 2011. The ideas behind the search are instructive to describe, so I will spend some time trying to do that before I discuss ...

The Great Neutrino Tsunami

February 23rd 1987 is a day indelibly imprinted on the minds of everyone interested in astrophysics. At 7:36 GMT that day, now 25 years ago, the big one hit us. There was no escape. For 13 seconds a tsunami of neutrinos, emanating from a giant star eleven ...

Diving into Euler-Lagrange: 1D (1 of 2)

Sophisticated physicists appreciate the dance of abstract symbols. I need to build something. The abstract is more real when made out of clay and pipe cleaners. In this blog on the 1D Euler Lagrange equations, beads (not clay) and pipe cleaners will be use ...

LHCb Measures Direct CP Violation In Bs Mesons

A long awaited confirmation that direct CP violation occurs in Bs mesons (particles composed of a b- and an s-quark) not unlike what happens to lighter mesons (the K0, the B0, and the D0) is coming from LHCb. In an article appeared yesterday in the Cornell ...
