For the Robbie Robertson fans.
Sigh...DeBroglie's equation for the speed of a matter wave crest is U = c^2/v. That can be taken two different ways : c^2 means mass-area(time) or c^2 means momentum-line(not-time). At c^2 LINE : 1 light year covered in 105 seconds.
Since U = c^2/v violates Einstein's c-limit, DeBroglie(a founder of Quantum Mechanics along with Planck)was regulated to the "crazy aunt alice" category by the relativists. But now the TRUTH emerges with this "spooky action at a distance"...MATTER WAVES pilgrim, MATTER WAVES....are linking the photons at c^2.
Thanks for the ping! :-)
One more step toward the Star Trek transporter.
BFLR
Line up five billiard balls in a row touching each other on a pool table. Drive the cue ball into the first and see the last billiard ball move across the table through the transfer of energy while the first four balls remain in place.
Actually a better analogy to this experiment would be if the middle three billiard balls were not there and the last billiard ball started moving when the first one was struck, without the two billiard balls ever touching.
Thanks Q for the ping.
A String Theory list ping, just because it's been a slow week, and it will probably be of interest. :')
Thanks for the ping!
And now the related stuff. Probably all dead links, plus, the droll humor is also from the files, and was dead in the first place.Cosmic Laws Like Speed of Light Might Be Changing, a Study FindsThe magnitude of the change apparently observed by the group is minute, amounting to just 1 part in 100,000 in a number called the fine structure constant over 12 billion years. That constant, also referred to as alpha, is defined in terms of more familiar quantities like the speed of light and the strength of electronic attractions within atoms... Considering the unexpected nature of the finding, both Dr. Glashow and Dr. Kolb said the chances were high that some more mundane explanation for the results would turn up.

The limitations in the design of such a "quantum computer" include the miniaturized components needed to control the effect, the needed cooling, and the power requirements. Laser breakthroughs would be needed to reduce the size and cost. But still, "the future's so bright, I got to wear shades."www.bearfabrique.org/Catastrophism/WALLSAN.TXTSansbury is a quiet spoken physicist from Connecticut. He is associated with the Classical Physics Institute, or CP Institute, of New York which publishes the Journal of Classical Physics. Sansbury's was a thousand dollar experiment using 10 nanosecond long pulses of laser light, one pulse every 400 nsec. At some distance from the laser was a photodiode detector. But in the light path, directly in front of the detector was a high speed electronic shutter (known as a Pockel cell) which could be switched to allow the laser light through to the detector, or stop it.
by Wal ThornhillBreaking the Light BarrierIn the most striking of the new experiments a pulse of light that enters a transparent chamber filled with specially prepared cesium gas is pushed to speeds of 300 times the normal speed of light. That is so fast that, under these peculiar circumstances, the main part of the pulse exits the far side of the chamber even before it enters at the near side. Dr. Chiao, whose own research laid some of the groundwork for the experiment, added that "there's been a lot of controversy" over whether the finding means that actual information--like the news of an impending accident--could be sent faster than c, the velocity of light. But he said that he and most other physicists agreed that it could not.Fast BreakResearchers say it is the most convincing demonstration yet that the speed of light—supposedly an ironclad rule of nature—can be pushed beyond known boundaries, at least under certain laboratory circumstances. "This effect cannot be used to send information back in time," said Lijun Wang, a researcher with the private NEC Institute. "However, our experiment does show that the generally held misconception that 'nothing can travel faster than the speed of light' is wrong." The achievement has no practical application right now, but experiments like this have generated considerable excitement in the small international community of theoretical and optical physicists. Wang said the effect is possible only because light has no mass; the same thing cannot be done with physical objects. Aephraim Steinberg, a physicist at the University of Toronto, said the light particles coming out of the cesium chamber may not have been the same ones that entered, so he questions whether the speed of light was broken.An Engineering Approach to Solar and Galactic Formation"In the most striking of the new experiments a pulse of light that enters a transparent chamber filled with specially prepared cesium gas is pushed to speeds of 300 times the normal speed of light. That is so fast that, under these peculiar circumstances, the main part of the pulse exits the far side of the chamber even before it enters at the near side."
by Neil B. ChristiansonMeta Research: Speed Limit of GravityThe team at the Harvard-Smithsonian Center for Astrophysics in Cambridge, Massachusetts report in the Jan. 29 issue of Physical Review Letters, the atoms change their magnetic spin just slightly -- a change that allows them to store information from the photons. Hitting the cloud of hot rubidium gas with another laser pulse releases the first pulse, they said. Usually, when a photon hits an atom -- even an atom in a highly reflective mirror -- it gets absorbed and heats up the atom, putting it into what physicists call a higher energy state.

What Advantage Is Slowing Light To 38 Mph Going To Have?
Scientists Hold Light Particles Captive
by Maggie Fox, Health and Science CorrespondentLight stopped in its tracksTo stop light altogether, the scientists have utilised a similar but far more powerful effect. The researchers cooled a gas of magnetically trapped sodium atoms to within a few millionths of a degree of absolute zero (-273 deg C). This would normally be opaque to light. But by illuminating it with a laser called a coupling beam, it can be made transparent, thereby allowing another laser pulse to pass through it. It is a process known as electromagnetically induced transparency. And, astonishingly, if the coupling laser is turned off while the probe pulse is inside the gas cloud, the probe pulse stops dead in its tracks. If the coupling beam is then turned back on, the probe pulse emerges intact, just as if it had been waiting to resume its journey.

Researchers Make Light Travel Backward, and Faster Than LightPrevious work has slowed light to a crawl. But in the new research, a pulse of light is given a negative speed and — as if just to make your head spin — the researcher says the experiment made light appear to exceed its theoretical speed limit... The research was reported in the May 12 issue of the journal Science. Though not normally stated in news reports, Science is a peer-reviewed journal. That means some experts read Boyd's paper and said it was good enough to publish... We're going to let Boyd do the explaining. This next sentence is the crux of it all:

"We sent a pulse through an optical fiber, and before its peak even entered the fiber, it was exiting the other end. Through experiments we were able to see that the pulse inside the fiber was actually moving backward, linking the input and output pulses."
"The pulse of light is shaped like a hump with a peak and long leading and trailing edges. The leading edge carries with it all the information about the pulse and enters the fiber first. By the time the peak enters the fiber, the leading edge is already well ahead, exiting. From the information in that leading edge, the fiber essentially 'reconstructs' the pulse at the far end, sending one version out the fiber, and another backward toward the beginning of the fiber."
..."Einstein said information can't travel faster than light, and in this case, as with all fast-light experiments, no information is truly moving faster than light," Boyd said.
A spokesperson at the university's communications department added this: "Everything that defines the pulse that enters, also defines the pulse that exits. But the energy of the light does not travel faster than light."
Like a wormhole in space.
Technically... ;')Light 'frozen' in its tracksA pulse of light has been stopped in its tracks with all its photons intact, reveal US physicists... Speeds of a few metres per second are now reached routinely in laboratories around the world. It is rather harder, however, to stop light completely and previous attempts have halted light but lost its photons in the process. Mikhail Lukin and colleagues at Harvard University in Cambridge, Massachusetts managed to stop light without this loss by firing a short burst of red laser light into a gas of hot rubidium atoms... The light in the control beams interacts with the rubidium atoms to create layers that alternately transmit and reflect the pulse... The pulse is set free when the control beams are turned off... In 2001, two groups reported they had stopped light (New Scientist 08/08/01). Lukin was involved in one of these experiments, the other was led by Lene Hau, now at Harvard... Lukin used hot rubidium atoms, Hau super-cooled sodium. Both managed to reduce the speed of light to zero however, by the time it had slowed to a halt, all of the photons had been absorbed. The pulse could be regenerated because the photons' energy was stored in the atoms. But while the pulse was stationary, technically, it contained no light at all.

A cloud of supercold sodium atoms. Sodium normally would be a solid at room temperature let alone cryogenic temperatures. How do they keep that from happening?
And time.....
They created quantum mechanics? I always thought they discovered what was already there ;)
