The Shape of Things that have Come

Timothy Birdnow

Researchers at Cornell have devised a "time cloak" by bending light waves around a bubble, speeding and slowing down the light so as to create a "hole in time" as this article is claiming.

From the piece:

"The General Theory of Relativity by Albert Einstein implies that gravity can cause time to slow down. Scientists have now shown that there is a way to stop time altogether; or maybe more accurately, to give the appearance that time has stopped by bending light around events to create a hole in time.

Recent scientific demonstrations have shown that objects can be made to disappear by bending the waves of visible light. The main idea behind this is that if light moves around an object instead of hitting it, it cannot be perceived. This makes the object in question invisible, at least to observers.

Cornell University scientists have used this concept to burrow a hole in time. This hole has a very short existence window, about 40 trillionths of a second, but imagine if this could be extended. Alex Gaeta, one of the physicists involved, states that slowing light down and speeding it up creates a gap in the light beam in time. This might make it seem as if the event had never occurred.

The time-stopping experiment, as described in their article in the journal Nature, used a laser beam aimed at a probe. The beam passed through a device that they named the time lens, which modifies the light beam’s temporal distribution. It allows them to do funny things with light in the time domain. Moti Fridman created a method which allowed them to change the frequency and wavelength of the beam. This meant that it moved at a different velocity, which in turn created the time gap."

Now we know where Obama's birth certificate went! Doubtless that was the first item the researchers attempted to cloak!

When the Book of Genesis begins with "let there be light" it was far more prescient than any materialists give it credit for; the Universe is little more than light. Matter is energy in a solid form, light turned hard, if you will. And time only exists in conjunction with light. And all of the physical laws of the Universe are predicated on their visibility and their relations in time, so they too are all predicated on light. Every physical law is tied to light and time, which themselves are intimiately tied to the observer. In the end, consciousness is necessary for the existence of the entire Universe!

It really is an astounding thought.

A couple of years ago, some physicists at the University of Rochester made a beam of light go backwards - and at a speed considerably greater than light! (Relativity was not violated here; the beam went back over the exact same path it had followed, thus not violating any fundamental principles, since INFORMATION was not moving faster than light, and the beam was not traversing any space but the limited one it had already traversed.)

According to the article:

It sounds nuts, but a scientist says his team has made light go backward. And this is not a simple trick of mirrors.

Previous 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.

If you totally confused, don't worry. This reporter doesn't get it either. Nor do a lot of really smart scientists.

"I've had some of the world's experts scratching their heads over this one," says Robert Boyd, a professor of optics at the University of Rochester. "It's weird stuff."

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 to publish.

That said, nobody would blame you if you stop here. Otherwise, grab a couple aspirin, have a look at depictions of the experiment in this graphic or this animation, and read on.

We're going to let Boyd do the explaining. And 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."

Let's put that another way, verbatim from a statement issued by the University of Rochester:

"As the pulse enters the material, a second pulse appears on the far end of the fiber and flows backward. The reversed pulse not only propagates backward, but it releases a forward pulse out the far end of the fiber. In this way, the pulse that enters the front of the fiber appears out the end almost instantly, apparently traveling faster than the regular speed of light."

What about Einstein, who said nothing can exceed light-speed?

"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."

End excerpt.

Now, imagine a particle moving through the fiber optics at the same time as the light pulse; what would you see if you had a teenie-tiny telescope to watch? I would think that as the light reversed the particle would seem to reverse as well. It's spin would appear retrograde, in fact, all of it's properties would appear retrograde. Now, a retrograde particle is an antiparticle. Did the particle become antimatter for a miniscule amou=mcnt of time?

There is an old theory, now largely ignored, that antimatter is really matter moving backwards in time, and that is why we don't see any large amounts around. Remember, Einstein's equation e=mc2? That means m=e/c2, which means that a LOT of energy can create a little matter. But Paul Dirac showed that this equation can be solved as either positive or negative. Einstein knew it, too, but assumed the imaginary equations were just noise. Dirac showed that, yes, there are indeed anti-particles, and the discovery of the positron followed shortly. In nature there are things called virtual particles, where energy forms a particle and it's antiparticle, and the two annihilate each-other immediately. The only place where matter is created is near charged black holes, where the charge pushes away one particle and the gravity sucks in another. But outside of that one has to look into a particle accelerator.

So the Universe should be both matter and antimatter in equal portions, yet the observable universe is all matter. Nobody has been able to figure out exactly where all that antimatter went, although there are some theories.

But one theory was that antimatter was moving backward in time.

Now, if you look at that particle going into the fiber optics where the light beam reverses, it would seem reversed, like antimatter. The next logical step is to conclude that it IS antimatter, but moving backward in time! The light, after all, is moving backward, and time is entirely predicated on light.

So, is this time travel? I know time travel is possible.

A casual glance at the United States is proof positive that time travel is possible; the U.S. is languishing in the 1930's, with Depression-era unemployment, government works projects designed to stimulate the economy, with a growing foreign threat being ignored by a Hooverian President. We also see the 1970's here, with complete with solar panels, fears of climate change, racial politics, high gas prices. I'm surprised Mr. Obama isn't wearing high heels and a polyester leisure suit!

Obama certainly has taken us for a spin in the way-back machine!

And he didn't even need physicists from Cornell or Rochester to help him with that!
