it seems like a long time since humanity has broached a major new paradigm-shifting scientific breakthrough. in the century since Einstein gave us relativity, we've created microwave ovens and cel phones, which seem in line with the path of technological improvement. the overall arc of history feels somewhat like a Dark Ages in terms of progress scientifically though. perhaps it was the perky optimism of the 1950s, Atomic Age, Jetsons cartoons sense of how much science would improve the world. perhaps it is our focus on the 1%'s need to be wealthier than us. and some days, i even wish to point the finger at our ongoing acceptance of fairy-tale gods and religions who need people to not think. but i still crave the answers which seem to be reachable.
It is a concept that forms a cornerstone of our understanding of the universe and the concept of time – nothing can travel faster than the speed of light. But now it seems that researchers working in one of the world's largest physics laboratories, under a mountain in central Italy, have recorded particles travelling at a speed that is supposedly forbidden by Einstein's theory of special relativity. Scientists at the Gran Sasso facility will unveil evidence on Friday that raises the troubling possibility of a way to send information back in time, blurring the line between past and present and wreaking havoc with the fundamental principle of cause and effect. They will announce the result at a special seminar at Cern – the European particle physics laboratory – timed to coincide with the publication of a research paper ( pdf ) describing the experiment.
How accurate is the decoder? A good decoder should produce a reconstruction that a neutral observer judges to be visually similar to the viewed movie. However, it is difficult to quantify human judgments of visual similarity. In this paper we use similarity in the motion-energy domain. That is, we quantify how much of the spatially localized motion information in the viewed movie was reconstructed.
What if our existence is a holographic projection of another, flat version of you living on a two-dimensional "surface" at the edge of this universe? In other words, are we real, or are we quantum interactions on the edges of the universe - and is that just as real anyway? Whether we actually live in a hologram is being hotly debated, but it is now becoming clear that looking at phenomena through a holographic lens could be key to solving some of the most perplexing problems in physics, including the physics that reigned before the big bang,what gives particles mass, a theory of quantum gravity. In 1982 a litttle known but epic event occured at the University of Paris, where a research team led by physicist Alain Aspect performed what may turn out to be one of the most important experiments of the 20th century.
The Universe as a Hologram by Michael Talbot Does Objective Reality Exist, or is the Universe a Phantasm? In 1982 a remarkable event took place. At the University of Paris a research team led by physicist Alain Aspect performed what may turn out to be one of the most important experiments of the 20th century. You did not hear about it on the evening news.
“It isn’t that the world of appearances is wrong; it isn’t that there aren’t objects out there, at one level of reality.
Researchers at Tokyo University have come up with a technology that is a first and significant step away from the mouse and keyboard – touchable holograms. [Hiroyuki Shinoda, Professor, Tokyo University]: "Up until now, holography has been for the eyes only, and if you'd try to touch it, your hand would go right through. But now we have a technology that also adds the sensation of touch to holograms." The technology consists of software that uses ultrasonic waves to create pressure on the hand of a user “touching” the projected hologram. Researchers are using two Wiimotes from Nintendo’s Wii gaming system to track a user’s hand.
The story that you’re about to read has created quite a stir among our editorial staff. The subject touches upon everything, literally everything that we humans do in our lives. And this is confrontational, disturbing and hopeful all at once. But that wasn’t the only reason for the commotion. There was also a continual discussion about the way this topic should be introduced. After all, writing about an energy field that connects man and matter and continually affects everything and everyone is not as quite as simple as the average article.

Photograph: Fabrice Coffrini/AFP/Getty Images Scientists may have caught their first glimpse of the elusive Higgs boson , which is thought to give mass to the basic building blocks of nature. Researchers at the Large Hadron Collider at Cern , the European particle physics lab near Geneva, announced the findings at a conference on Friday .

The human mind has been long concerned about the existence of other parallel worlds . While many people still consider it nothing more than a weird scientific fantasy, a certain number of scientists nowadays not only are ready to take this hypothesis seriously but also find evidence in favour of it. Researchers from the University College London have found signs of the gravitation impact of other worlds on our universe. The discovery was made in the course of studying maps of the cosmic microwave background , which preserved in space from the initial stages of existence. The analysis has identified several round anomalous zones , which are characterized by high temperature. According to experts, this anomaly can be explained by the gravitational impact of other worlds on ours .
Clarke's Three Laws are three "laws" of prediction formulated by the British writer Arthur C. Clarke . They are: When a distinguished but elderly scientist states that something is possible, he is almost certainly right. When he states that something is impossible, he is very probably wrong.

One of modern physics’ most cherished ideas is quantum chromodynamics, the theory that describes the strong nuclear force, how it binds quarks and gluons into protons and neutrons, how these form nuclei that themselves interact. This is the universe at its most fundamental. So an interesting pursuit is to simulate quantum chromodynamics on a computer to see what kind of complexity arises. The promise is that simulating physics on such a fundamental level is more or less equivalent to simulating the universe itself. There are one or two challenges of course. The physics is mind-bogglingly complex and operates on a vanishingly small scale.
Well…it can almost see in the dark. Scientists at the Lawrence Berkeley National Laboratory have just announced that they’ve been able to confirm a new high-efficiency solar cell design that handles pretty much the entire solar spectrum. To ice the solar cake, the new technology can be manufactured using ordinary low-cost processes that are currently in use. Harnessing the Full Spectrum for Solar Power A conventional solar cell uses one kind of semiconductor, which captures light from one part of the spectrum. The new solar cell uses different materials, stacked in layers, that respond to different wavelengths.
