    HomeScience NASA’s Eagle Works: The Manhattan project of space travel. Karim Immanuel Chemlal A working microwave thruster would radically cut the cost of satellites and space stations and extend their working life, drive a plethora of suddenly affordable deep-space missions, and take astronauts to Mars in days to weeks rather than months. In 2011 the NASA engineering directorate created the Advanced propulsion team unofficially known as the “Eagleworks”. This rock star team of scientists and engineers are headed by Harold ‘Sonny’ White, engineer and applied physicist of NASA’s propulsion team at the Johnson space centre. The goal of the Eagle...
  • 'Impossible' Space Engine May Actually Work, NASA Test Suggests

    The roots of the propulsion system tested by the NASA team trace back to a British researcher named Roger Shawyer, who claims that his "EmDrive" generates thrust by rocketing microwaves around in a chamber. There is no need for propellant, as solar power can be used to produce the microwaves. Shawyer says that his company, Satellite Propulsion Research Ltd., has successfully tested experimental versions of the thruster. But many scientists have dismissed or downplayed such claims, saying the propulsion system violates the law of conservation of momentum, Wired UK reported. In 2012, however, a team of Chinese researchers built their...

    Until yesterday, every physicist was laughing at this engine and its inventor, Roger Shawyer. It's called the EmDrive and everyone said it was impossible because it goes against classical mechanics. But the fact is that the quantum vacuum plasma thruster works and scientists can't explain why. Shawyer's engine is extremely light and simple. It provides a thrust by "bouncing microwaves around in a closed container." The microwaves are generated using electricity that can be provided by solar energy. No propellant is necessary, which means that this thrusters can work forever unless a hardware failure occurs. If real, this would be...

    Let me geek out on you (I love science) and explain to you the science (I love science) and why this had previously been confined to the pages of science fiction (I am a nerd; and oh Dear Sweet Bunsen-Burner Lighting Lord, do I love science). So it's a pretty firmly established principle that every act causes, and requires, an equal and opposite reaction. If I understand this right (did I mention I love science?), this means that any space vessel will have to carry with it an enormous amount of reaction mass. You can't -- we think, or thought...

    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 — Beyond the security gate at the Johnson Space Center’s 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...

    The Case for a Solar Influence on Certain Nuclear Decay Rates Peter Sturrock, Ephraim Fischbach, Daniel Javorsek II, Jere Jenkins, Robert Lee (Submitted on 16 Jan 2013) Power-spectrum analyses of the decay rates of certain nuclides reveal (at very high confidence levels) an annual oscillation and periodicities that may be attributed to solar rotation and to solar r-mode oscillations. A comparison of spectrograms (time-frequency displays) formed from decay data and from solar neutrino data reveals a common periodicity with frequency 12.5 year-1, which is indicative of the solar radiative zone. We propose that the neutrino flux is modulated by the...

    The speed of light is constant, or so textbooks say. But some scientists are exploring the possibility that this cosmic speed limit changes, a consequence of the nature of the vacuum of space. The definition of the speed of light has some broader implications for fields such as cosmology and astronomy, which assume a stable velocity for light over time. For instance, the speed of light comes up when measuring the fine structure constant (alpha), which defines the strength of the electromagnetic force. And a varying light speed would change the strengths of molecular bonds and the density of nuclear

    Scientists said on Thursday they recorded particles travelling faster than light - a finding that could overturn one of Einstein's fundamental laws of the universe. Antonio Ereditato, spokesman for the international group of researchers, said that measurements taken over three years showed neutrinos pumped from CERN near Geneva to Gran Sasso in Italy had arrived 60 nanoseconds quicker than light would have done. "We have high confidence in our results. We have checked and rechecked for anything that could have distorted our measurements but we found nothing," he said. "We now want colleagues to check them independently."

    The way gravity effects quantum particles proves that it cannot be an emergent phenomenon, says physicist. One of the most exciting ideas in modern physics is that gravity is not a traditional force, like electromagnetic or nuclear forces. Instead, it is an emergent phenomenon that merely looks like a traditional force. This approach has been championed by Erik Verlinde at the University of Amsterdam who put forward the idea in 2010. He suggested that gravity is merely a manifestation of entropy in the Universe, which always increases according to the second law of thermodynamics. This causes matter distribute itself in...

    Exclusive from New Scientist Hidden extra dimensions are causing measurements of the strength of gravity at different locations on Earth to be affected by the planet's magnetic field, French researchers say. This is a controversial claim because no one has ever provided experimental evidence to support either the existence of extra dimensions or any interaction between gravity and electromagnetism. But lab measurements of Newton's gravitational constant G suggest that both are real. Newton's constant, which describes the strength of the gravitational pull that bodies exert on each other, is the most poorly determined of the constants of nature. The two...

    RICHARD FEYNMAN, Nobel laureate and physicist extraordinaire, called it a “magic number” and its value “one of the greatest damn mysteries of physics”. The number he was referring to, which goes by the symbol alpha and the rather more long-winded name of the fine-structure constant, is magic indeed. If it were a mere 4% bigger or smaller than it is, stars would not be able to sustain the nuclear reactions that synthesise carbon and oxygen atoms. One consequence would be that squishy, carbon-based life would not exist. Why alpha takes on the precise value it does, so delicately fine-tuned for...

The year was 1908, and the German mathematician Hermann Minkowski had been trying to make sense of Albert Einstein's hot new idea - what we now know as special relativity - describing how things shrink as they move faster and time becomes distorted. "Henceforth space by itself and time by itself are doomed to fade into the mere shadows," Minkowski proclaimed, "and...

    The phenomenon of time dilation is a strange yet experimentally confirmed effect of relativity theory. One of its implications is that events occurring in distant parts of the universe should appear to occur more slowly than events located closer to us. For example, when observing supernovae, scientists have found that distant explosions seem to fade more slowly than the quickly-fading nearby supernovae. The effect can be explained because (1) the speed of light is a constant (independent of how fast a light source is moving toward or away from an observer) and (2) the universe is expanding at an accelerating...
