  • Closing the 'free will' loophole: Using distant quasars to test Bell's theorem

    Astronomers propose an experiment that may close the last major loophole of Bell's inequality -- a 50-year-old theorem that, if violated by experiments, would mean that our universe is based not on the textbook laws of classical physics, but on the less-tangible probabilities of quantum mechanics. Such a quantum view would allow for seemingly counterintuitive phenomena such as entanglement, in which the measurement of one particle instantly affects another, even if those entangled particles are at opposite ends of the universe. Among other things, entanglement -- a quantum feature Albert Einstein skeptically referred to as "spooky action at a distance"...

    HOUSTON ó Beyond the security gate at the Johnson Space Centerís 1960s-era campus here, inside a two-story glass and concrete building with winding corridors, there is a floating laboratory. Harold G. White, a physicist and advanced propulsion engineer at NASA, beckoned toward a table full of equipment there on a recent afternoon: a laser, a camera, some small mirrors, a ring made of ceramic capacitors and a few other objects. He and other NASA engineers have been designing and redesigning these instruments, with the goal of using them to slightly warp the trajectory of a photon, changing the distance it...

    Two new studies to be published in the European Physical Journal D demonstrate that the speed of light is variable in real space. Textbook explanations of the speed of light assume that light travels in a vacuum, but space is not a vacuum. Ö It is not expected that the small variation in the speed of light which has been found will affect the universally accepted theories of particle physics and quantum mechanics to a large extent. However, the studies are proof that the speed of light may be variable, and shows that the mathematical treatments that have long been...

    New theory describes faster than light travel, could explain CERN's results Some of the greatest physicists of the twentieth century, including Albert Einstein, consider the speed of light a sort of universal "speed limit". †But over the past couple decades physicists theorized that it should be possible to break this law and get away with it -- to†travel faster than the speed of light. I. CERN Results Potentially Described One of several possible routes to faster-than-light travel was†potentially demonstrated†when researchers at†CERN, the European physics organization known for†maintaining the Large Hadron Collider, sent high-energy particles through the Earth's crust from†Geneva, Switzerland...
  • New Experiment Shows Neutrinos Do Not Travel Faster Than Light

    There was definitely some excitement in the physics world last Fall when the OPERA Collaboration in Gran Sasso, Italy, announced that they had measured neutrinos traveling faster than the speed of light. Iíve been skeptical of this announcement since the first day, and in the intervening months since, things have been looking worse for the measurement. This culminated last month when the OPERA Collaboration admitted that the faster-than-light measurement may have been due to a simple measurement error. Now, in what may well be the final nail in the coffin for the claim that neutrinos travel faster than light, scientists...
  • Particles recorded moving faster than light: CERN

    An international team of scientists has recorded neutrino particles traveling faster than the speed of light, a spokesman for the researchers said on Thursday -- in what could be a challenge to one of the fundamental rules of physics. If confirmed, the discovery would overturn a key part of Albert Einstein's 1905 theory of special relativity, which says that nothing in the universe can travel faster than light.
  • Recent articles in Scientific American have talked about traveling faster than light.

    Einstein's special theory of relativity predicts that nothing can exceed the speed of light. But special relativity applies when spacetime is flat. When spacetime is curved, the theory applies only "locally"--that is, over regions of spacetime small enough to be considered flat. Consider the analogy of a plane that is tangent to a sphere. The flat geometry of the plane is a good approximation to the geometry of the sphere when the size of the plane is very small compared to the sphere's radius of curvature.

    The Future According to Professor Paul Davies "Scientists have no doubt whatever that it is possible to build a time machine to visit the future". Since the publication of Einsteinís Special Theory of Relativity in 1905, few, if any, scientists would dispute that time travel to the future is perfectly possible. According to this theory, time runs slower for a moving person than for someone who is stationary. This has been proven by experiments using very accurate atomic clocks. In theory, a traveller on a super high-speed rocket ship could fly far out into the Universe and then come back...
