POPSTime to test time Yet if Hogan's ideas are right, noise associated with this fundamental fuzziness should be prominent at GEO600, a joint British and German machine operating near Hannover, Germany, that is searching for gravitational waves. These waves are thought to arise during events such as the massive cosmic collisions of black holes and neutron stars. Confirmation of the idea — which could come as experimental upgrades to GEO600 are put in place over the coming year — would be a big step towards a verifiable quantum theory of gravity, a long-sought unification of quantum mechanics (the physics of the very small) with general relativity (the physics of the very big). Hogan outlines his predictions in a paper published on 30 October in Physical Review D1.

POPSEntangled Particles and Free Will My Unitarian Universalist pastor just gave a sermon on this very "problem." It is mind blowing to think that the entangled particles communicate at a rate faster than the speed of light.

POPSFermilab Looks for Visitors from Another Dimension The prospect of extra dimensions is fascinating. ET might already be here in a neighbour dimension. :-) Estimated to cost about $15 million, the MicroBooNE tank would be located near the MiniBooNE detector at Fermilab so that it could observe the same beam of neutrinos. This past June the lab’s physics advisory committee approved the design phase for the project; if all goes well, the detector could begin operating as soon as 2011.

POPSPhysicists investigate how time moves forward This provides an orientation, or arrow of time, and it is generally believed that all other time asymmetries, such as our sense that future and past are different, are a direct consequence of this thermodynamic arrow.” In their study, Feng and Crooks have developed a method to accurately measure “time asymmetry” (which refers to our intuitive concept of time, that the past differs from the future, in contrast with time symmetry, where there is no distinction between past and future). They began by investigating the increase in energy dissipation, or entropy, in various arrangements. While time blatantly moves forward in the macroscopic world, the direction of time becomes confusing on the scale of a single molecule

POPSDo subatomic particles have free will? But physicists all the way back to Einstein have been unhappy with this idea. Einstein famously grumped, “God does not play dice.” And indeed, ever since the birth of quantum mechanics, some physicists have offered alternate interpretations of its equations that aim to get rid of this indeterminism. The most famous alternative is attributed to the physicist David Bohm, who argued in the 1950s that the behavior of subatomic particles is entirely determined by “hidden variables” that cannot be observed. Conway and Kochen say this search is hopeless, and they claim to have proven that indeterminacy is inherent in the world itself, rather than just in quantum theory. And to Bohmians and other like-minded physicists, the pair says: Give up determinism, or give up free will. Even the tiniest bit of free will.

POPSPhysicists Seek Answers to Quantum Correlations The physicists ruled out several possible classical explanations for the instantaneous communication. For one thing, they showed that the photons did not share information before leaving Geneva, and so they didn´t travel knowing about each other´s properties. In another test, the scientists showed that no communication could have occurred through a different reference frame, as might happen because of the photons´ high speeds. According to Einstein´s theory of relativity, observers moving at high speeds can get different measurements of the same event because they have different reference frames. But, by performing tests over a complete rotation of the Earth, the researchers ruled out this possibility. "We think space and time are important because that´s the kind of monkeys we are,"

POPSBuilding 'The Matrix' Feynman envisioned, a general purpose, programmable quantum computer could itself carry out quantum simulations. But such machines are still decades away, most researchers say, while machines designed only for quantum simulations may become available sooner.

POPSExtraterrestrial Particle Accelerator I recently read an excellent book titled "Decipher," about a diverse group of people trying to save the Earth. A linguist that specialized in dead languages like Chaldean and Sumerian... A CIA remote viewer.. A Construction Engineer for a Oil Company... An Archaeologist.. A Quantum Scientist/Mathematician focused on Chaos Theory... A Crack team of Marines with the ever noble squared-jaw leader. Their goal was to decipher a base 60 language that ad been left imprinted on crystal matrices tens of thousands years old with a carbon-60 elemental make up.. Read it if you can find it, it is amazing. The Particle Accelerator here was featured in that book and the Physicist was spouting off about these theories of mini-black holes and space/time distortion. Thus article goes one better as it alleges that the Collider is the only NON-TOP SECRET unit being used and many more exist...

POPSThe Occult Nature of Light "Both God and Light exist outside of space & time." "There is something very suggestive about no-space, no-time, Light, and God. I don't know what it is but there's something deep and profound here that I wish I understood." "Light propagation may actually create space & time. The zero point field inertial hypothesis implies that the most fundamental property of matter, namely mass, is created by light." - Dr. Bernard Haisch, astrophysicist, author of "The God Theory"

POPSCan information get back out of black holes? With this assumption in hand, the team recalculated what the centre of a black hole might look like. To simplify their equations, they used only two dimensions instead of the three dimensions of space and one of time that exist in our Universe. In a two-dimensional system, they found that the singularity vanished and was replaced by a bizarre region where quantum fluctuations ran wild. Space-time in that part of the hole would become so unpredictable that all conventional ideas of cause and effect would break down. "Classical intuition fails in that region, but quantum mechanics is definitely happy," says Ashtekar, who will report the results in the 20 May issue of Physical Review Letters 1. If black holes behave in the way Ashtekar predicts, information will never be lost and quantum mechanics will continue to function, even in the extreme environment beyond the event horizon.

POPSAt Ten, Dark Energy "Most Profound Problem" in Physics A decade later, a new suite of experiments may pin down the properties of dark energy and solve what some experts are calling "the most profound problem" in modern physics. "This is game-changing science," Michael Turner, a cosmologist at the University of Chicago, told a packed auditorium during the Decade of Dark Energy Symposium held last week at STScI. "We've gone from establishing the phenomenon to probing the underlying cause," he said. "We're not anywhere near the point where it's time to give dark energy a rest."

POPSPhysicists Demonstrate How Information Can Escape From Black Holes Hawking's idea was generally accepted by physicists until the late 1990s, when many began to doubt the assertion. Even Hawking himself renounced the idea in 2004. Yet no one, until now, has been able to provide a plausible mechanism for how information might escape from a black hole. A team of physicists led by Abhay Ashtekar, Holder of the Eberly Family Chair in Physics and director of the Penn State Institute for Gravitation and the Cosmos, now has discovered such a mechanism. Broadly, their findings expand space-time beyond its assumed size, thus providing room for information to reappear.

POPSQuantum computers take step toward practicality In computing, a logic gate is built to accept a set of inputs and, depending on their properties, provide a specific output. In the binary logic found in today's electrical computers, a certain gate will yield a "1" only if all of its inputs are "1"s. Otherwise it will yield a "0." Similarly, a quantum photonic gate would work by detecting the properties of input photons from two light beams, called "control" and "signal," and then producing an output based on those, such as by flipping the polarization of one of the input photons.
