    In today's technological age, it might seem silly for intelligent people to consider a spiritual world where beings we cannot see might exist. Oh it's fine to read books and watch Hollywood movies about the afterlife and spirits that roam the netherworld but that's all make believe, not the real world. In the real world we are taught that reality consists of what we can touch, taste, see, hear, smell, and that the spirit world is for those weak minded individuals who use religion as a crutch to get through the day. However, what if I told you that...
  • ‘Spooky action’ builds a wormhole between ‘entangled’ particles

    Quantum entanglement, a perplexing phenomenon of quantum mechanics that Albert Einstein once referred to as “spooky action at a distance,” could be even spookier than Einstein perceived. Physicists at the University of Washington and Stony Brook University in New York believe the phenomenon might be intrinsically linked with wormholes, hypothetical features of space-time that in popular science fiction can provide a much-faster-than-light shortcut from one part of the universe to another. But here’s the catch: One couldn’t actually travel, or even communicate, through these wormholes, said Andreas Karch, a UW physics professor. Quantum entanglement occurs when a pair or a...

    Most scientists would probably say that the concept of an afterlife is either nonsense, or at the very least unprovable. Yet one expert claims he has evidence to confirm an existence beyond the grave—and it lies in quantum physics. Professor Robert Lanza claims the theory of biocentrism teaches that death as we know it is an illusion created by our consciousness. … Biocentrism is classed as the theory of everything and comes from the Greek for “life center”. It is the believe that life and biology are central to reality and that life creates the universe, not the other way...

    "It is widely accepted now that, without a doubt, information is physical and quantum physics provides the rules of that physical behavior," George Mason University computer science professor Richard Gomez told NewsFactor. Alan Turing might be considered the "John Forbes Nash of computer science" -- a troubled young Princeton genius who achieved prominence in the 1950s. Turing published one of the top 10 papers in all of 20th-century science -- "On the Computability of Numbers." He killed himself over a conviction for homosexuality at the height of his genius, but since his death, his definition of "computability" has stood untouched...

    Now physicists at the University of Vienna in Austria have "virtually intertwined" or entangled two particles spinning faster than ever in opposite directions. Entanglement occurs when two particles remain connected so that actions performed on one affect the other, despite the distance between them. (Einstein referred to this eerie connection as "spooky action at a distance.") In the new study, Anton Fickler and his colleagues entangled two photons that had a high orbital angular momentum, a property that measures the twisting of a wave of light. In quantum physics, particles such as photons can behave as particles and waves. Such...

    Physicists have proposed an experiment that could force us to make a choice between extremes to describe the behaviour of the Universe. The proposal comes from an international team of researchers from Switzerland, Belgium, Spain and Singapore, and is published today in Nature Physics. It is based on what the researchers call a 'hidden influence inequality'. This exposes how quantum predictions challenge our best understanding about the nature of space and time, Einstein's theory of relativity. "We are interested in whether we can explain the funky phenomena we observe without sacrificing our sense of things happening smoothly in space and...

    A group of physicists at the University of Glasgow is claiming a first: taking photos of entangled photons. In this paper in Nature (hooray for free access!), they explain that their 201 x 201 pixel images captured around 2,500 different entangled quantum states. The entangled photons were imaged using different lens configurations to capture correlations of position and momentum – the characteristics (to shorthand Heisenberg’s uncertainty principle) that mutually preclude excessive knowledge about a given quantum system. From the 100,000 images taken by their setup (pictured*), the scientists say they were able to observe 2,500 states which they described as...

    In a paper published in the March 29 issue of the journal Nature, the scientists describe the emergence of “spontaneous coherence,” “spin textures” and “phase singularities” when excitons—the bound pairs of electrons and holes that determine the optical properties of semiconductors and enable them to function as novel optoelectronic devices—are cooled to near absolute zero. This cooling leads to the spontaneous production of a new coherent state of matter which the physicists were finally able to measure in great detail in their basement laboratory at UC San Diego at a temperature of only one-tenth of a degree above absolute zero....

    Researchers have bent one of the most basic rules of quantum mechanics, a counterintuitive branch of physics that deals with atomic-scale interactions. Its "complementarity" rule asserts that it is impossible to observe light behaving as both a wave and a particle, though it is strictly both. In an experiment reported in Science, researchers have now done exactly that. They say the feat "pulls back the veil" on quantum reality in a way that was thought to be prohibited by theory. Quantum mechanics has spawned and continues to fuel spirited debates about the nature of what we can see and measure,...

    When probing the deepest reaches of the Cosmos or magnifying our understanding of the quantum world, a whole host of mysteries present themselves. This is to be expected when pushing our knowledge of the Universe to the limit. But what if a well-known -- and apparently constant -- characteristic of matter starts behaving mysteriously? This is exactly what has been noticed in recent years; the decay rates of radioactive elements are changing. This is especially mysterious as we are talking about elements with "constant" decay rates -- these values aren't supposed to change. School textbooks teach us this from an...

    An artificial "black hole" designed to capture wayward atoms has been created. It paves the way for an atom trap that could yield previously unknown states of matter. A team led by Lene Hau of Harvard University has mimicked the death spiral of matter falling into a cosmic black hole by applying a voltage across a carbon nanotube – a rolled-up sheet of carbon atoms. This created a powerful electric field that tugged at nearby rubidium atoms, which had been chilled to a fraction of a degree above absolute zero: a positive charge on the surface of the nanotubes attracts...

    Was Newton right and Einstein wrong? It seems that unzipping the fabric of spacetime and harking back to 19th-century notions of time could lead to a theory of quantum gravity. Physicists have struggled to marry quantum mechanics with gravity for decades. In contrast, the other forces of nature have obediently fallen into line. For instance, the electromagnetic force can be described quantum-mechanically by the motion of photons. Try and work out the gravitational force between two objects in terms of a quantum graviton, however, and you quickly run into trouble—the answer to every calculation is infinity. But now Petr Hořava,...

    Science fiction looks closer to becoming science fact. Parallel universes really do exist, according to a mathematical discovery by Oxford scientists that sweeps away one of the key objections to the mind boggling and controversial idea. The work has wider implications since the idea of parallel universes sidesteps one of the key problems with time travel. Every since it was given serious lab cred in 1949 by the great logician Kurt Godel, many eminent physicists have argued against time travel because it undermines ideas of cause and effect to create paradoxes: a time traveller could go back to kill his...

    Harvard University researchers have halted a pulse of laser light in its tracks and revived it a fraction of a millimeter away. Here's the twist: they stopped it in a cloud of supercold sodium atoms, known as a Bose-Einstein condensate (BEC), and then restarted it in a second, distinct BEC as though the pulse had spookily jumped between the two locations. "It's odd," says atomic physicist Lene Hau, the team's leader.

PAUL QUINCEY The birth of quantum mechanics can be dated to 1925, when physicists such as Werner Heisenberg and Erwin Schrödinger invented mathematical procedures that accurately replicated many of the observed properties of atoms. The change from earlier types of physics was dramatic, and pre-quantum physics was soon called classical physics in a kind of nostalgia for the...

One must keep both the particles and force fields of the old physics in addition to the new quantum wave function. Contrary to Bohr, we can picture the motion of particles in space at the quantum level , but there is a new kind of quantum force in addition to the classical forces of electromagnetism, gravity and even the strong and weak forces of modern high energy physics.

Nestled among queries about black holes and the nature of dark matter and dark energy were questions that wandered beyond the traditional bounds of physics to venture into areas typically associated with the life sciences. One of the Gross's questions involved human consciousness.
