Faster-than-light radio waves could revolutionize computer industries



Scientists have been plagued by Einstein’s theories which state nothing can travel faster than light. But over the past decade or so, we have seen a new branch of physics theorized, one which might give Einstein cause for pause. It’s called Superluminal Electromagnetic Field / Wave Propagation, which is basically a form of faster than light relativity. Experiments have been conducted by several scientists which involve light and radio sources traveling at speeds well in excess of the speed of light. Seem possible?

Earlier this year, a physicist called John Singleton created an application of this theory which he believes could greatly advance semiconductors.

Accelerated radio waves: A revolution in semiconductor industry?

Scientist John Singleton created an interesting device that accelerates the radio waves until they pass the speed of light. Yes, you've read that correctly - by using a process that is similar to the way Pulsar stars emit light - John jerked radio waves until they caved in and passed their theoretical speed barrier.

Singleton stated that usages for his device are enormous: "Because nobody's really thought about things that travel faster than light before, this is a wide-open technological field". This discovery could revolutionize medical, communication, semiconductor, space exploration fields.

Most people think Einstein said that nothing can travel faster than the speed of light, but that's not really the case, Singleton said.

Einstein predicted that particles and information can't travel faster than the speed of light — but phenomenon like radio waves? That's a different story, said Singleton, a Los Alamos National Laboratory Fellow.

Singleton has created a gadget that abuses radio waves so severely that they finally give in and travel faster than light.

"Because nobody's really thought about things that travel faster than light before, this is a wide-open technological field," Single ton said.

One possible use for the resulting speedy radio waves — which are packed into a very powerful wave the size of a pencil point — could be the creation of a new generation of cell phones that communicate directly to satellites, rather than transmitting through relay towers as they now do.

SUGAR -- Detecting Black Holes from Gravity Waves

Gravitational waves are predicted by Einstein's 1916 general theory of relativity, but they are notoriously hard to detect and it's taken many decades to come close to observing them. Now, with the help of a supercomputer named SUGAR (Syracuse University Gravitational and Relativity Cluster), two years of data collected by the Laser Interferometer Gravitational-Wave Observatory (LIGO) will be analyzed to find gravitational waves. Once detected, it is hoped that the location of some of the Universes most powerful collisions and explosions will be found, perhaps even hearing the distant ringing of celestial black holes…

ScienceDaily (Feb. 10, 2008) — Scientists hope that a new supercomputer being built by Syracuse University's Department of Physics may help them identify the sound of a celestial black hole. The supercomputer, dubbed SUGAR (SU Gravitational and Relativity Cluster), will soon receive massive amounts of data from the California Institute of Technology (Caltech) that was collected over a two-year period at the Laser Interferometer Gravitational-Wave Observatory (LIGO).
