Faster-than-light pulsar radio waves found

Are the elites prepping us peasants to accept the "unthinkable" ?? Seems like star travel is almost within our grasp ??

And you thought you couldn't go faster than light

Astrophysicists working out of the University of Texas at Brownsville have been studying an interesting pulsar about 10,000 light years away from us (a pulsar is a highly magnetic, spinning corpse of a dead star). Over the course of three days of monitoring, radio waves emitted from the pulsar seem to have been traveling faster than the speed of light.

You might have heard that faster-than-light travel is impossible. This is not entirely true -- there are a couple of catches which allow for F.T.L velocities. One such catch, as originally proposed by Mr. Einstein, is that something can travel faster than light if it does not contain information. This physical law has been observed on Earth in experiments, but with this pulsar (if confirmed), this is the first time this sort of thing has been observed off of our planet. What does or does not constitute information in this context however, is the subject of both rigorous study and debate.

The radio pulse from the pulsar is suspected to have picked up some of the excess speed by passing through a cloud of neutral hydrogen atoms, which causes the radio waves to increase their electromagnetic wavelength (a process called "anomalous dispersion").

(Note: pictured above is some other pulsar, not Pulsar PSR B1937+21 from this research. Pulsar PSR B1937+21 is the second fastest spinning pulsar yet cataloged, and spins about 642 times around every second.)

'THEY"will try that more and more to break our human nature and belief systems so we can accept "they evil " with not confrontation

Single Photons Observed at Seemingly Faster-Than-Light Speeds

One of these days...we shall discover the unthinkable...
Single Photons Observed at Seemingly Faster-Than-Light Speeds
http://www.sciencedaily.com/releases/2010/01/100126175921.htm

ScienceDaily (Jan. 27, 2010) — Researchers at the Joint Quantum Institute (JQI), a collaboration of the National Institute of Standards and Technology and the University of Maryland at College Park, can speed up photons (particles of light) to seemingly faster-than-light speeds through a stack of materials by adding a single, strategically placed layer.

At the boundaries between layers, the photon creates waves interfering with each other, affecting its transit time. (Credit: JQI)

This experimental demonstration confirms intriguing quantum-physics predictions that light's transit time through complex multilayered materials need not depend on thickness, as it does for simple materials such as glass, but rather on the order in which the layers are stacked. This is the first published study of this dependence with single photons.

Strictly speaking, light always achieves its maximum speed in a vacuum, or empty space, and slows down appreciably when it travels through a material substance, such as glass or water. The same is true for light traveling through a stack of dielectric materials, which are electrically insulating and can be used to create highly reflective structures that are often used as optical coatings on mirrors or fiber optics.

In a follow up to earlier experimental measurements, the JQI researchers created stacks of approximately 30 dielectric layers, each about 80 nanometers thick, equivalent to about a quarter of a wavelength of the light traveling through it. The layers alternated between high (H) and low (L) refractive index material, which cause light waves to bend or reflect by varying amounts. After a single photon hits the boundary between the H and L layers, it has a chance of being reflected or passing through.

When encountering a stack of 30 layers alternating between L and H, the rare photons that completely penetrate the stack pass through in about 12.84 femtoseconds (fs, quadrillionths of a second). Adding a single low-index layer to the end of this stack disproportionately increased the photon transit time by 3.52 fs to about 16.36 fs. (The transit time through this added layer would be only about 0.58 fs, if it depended only upon the layer's thickness and refractive index.) On the contrary, adding an extra H layer to a stack of 30 layers alternating between H and L would reduce the transit time to about 5.34 fs, so that individual photons seem to emerge through the 2.6-micron-thick stack at superluminal (faster-than-light) speeds.

What the JQI researchers are seeing can be explained by the wave properties of light. In this experiment, the light begins and ends its existence acting as a particle -- a photon. But when one of these photons hits a boundary between the layers of material, it creates waves at each surface, and the traveling light waves interfere with each other just as opposing ocean waves cause a riptide at the beach. With the H and L layers arranged just right, the interfering light waves combine to give rise to transmitted photons that emerge early. No faster than light speed information transfer occurs because, in actuality, it is something of an illusion: only a small proportion of photons make it through the stack, and if all the initial photons were detected, the detectors would record photons over a normal distribution of times.
