Gamma-ray observations shrink known grain size of spacetime

Smaller dots, Georges, please. In their efforts to unify quantum theory and gravity, theoretical physicists have likened spacetime to a Georges Seurat painting, composed of tiny dots or lumps that meld to form a seemingly smooth picture. But if spacetime really does have a grainy structure on the smallest scales, the cosmic painter may need to get finer brushes, a new study reveals.Office 2010 download is available now!

The study, published online October 28 in Nature, suggests that the dots that may compose spacetime must be smaller than one-hundred-thousandth of a trillionth of the size of a proton. This new limit on the graininess of spacetime is one-thousandth the size that previous, less sensitive experiments had indicated.By using Office 2010 Professional, you can save your money and time.

Sylvain Guiriec of NASA’s Marshall Space Flight Center and the University of Alabama in Huntsville and his colleagues used a powerful but indirect method to examine the structure of spacetime. The team measured the relative difference in the speed of two particles of light, Office 2007 key is available here. 

or photons, of widely different energies. Both photons were emitted by a cosmic explosion known as a short-lived gamma-ray burst.Many people like buy Office 2010 Home.

Many theories that seek to explain the action of gravity on subatomic scales are premised on the notion that space is lumpy or foamy on the tiniest of scales. Office 2007 is so powerful.

Such theories also suggest that the speed of light is not constant but varies with a photon’s energy — in contradiction to Einstein’s theory of special relativity. Microsoft Office is so great!

The more energetic the photon is, the slower its speed. In simplified terms, that’s because higher energy photons have shorter wavelengths, which makes them more likely to bump into tiny lumps in spacetime and to be slowed by those structures.Office Professional 2010 is great!

The rats that had been eating junk food started running more and more. Office 2010 is powerful!

This behavior suggested that the junk-food–eating rats needed more brain stimulation to feel good compared with rats on a normal diet. In other words, their pleasure centers were becoming less sensitive and the junk food didn’t make them feel good unless they ate more and more. Microsoft Office 2007 is welcomed by the whole world.

The same process happens in the brains of drug addicts. As the pleasure center becomes numb, the addict has to consume more of the drug to feel good.Microsoft Office 2010 is the best software in the world.
