Scientists receive $1.3 million to study new propulsion idea for spacecraft - University of Plymouth. Spacecraft and satellites could in future be launched into space without the need for fuel, thanks to a revolutionary new theory. Dr Mike McCulloch, from the University of Plymouth, first put forward the idea of quantised inertia (QI) – through which he believes light can be converted into thrust – in 2007. He has now received $1.3million from the United States Defense Advanced Research Projects Agency (DARPA) for a four-year study which aims to make the concept a reality. The QI theory predicts that objects can be pushed by differences in the intensity of so-called Unruh radiation in space, similar to the way in which a ship can be pushed towards a dock because there are more waves hitting it from the seaward side. The theory has already predicted galaxy rotation without dark matter, and the fact that if a system is accelerated enough – such as a spinning disc or light bouncing between mirrors – the Unruh waves it sees can be influenced by a shield.

The Universe Is Not Locally Real, and the Physics Nobel Prize Winners Proved It. One of the more unsettling discoveries in the past half a century is that the universe is not locally real. In this context, “real” means that objects have definite properties independent of observation—an apple can be red even when no one is looking.

“Local” means that objects can be influenced only by their surroundings and that any influence cannot travel faster than light. Investigations at the frontiers of quantum physics have found that these things cannot both be true. Instead the evidence shows that objects are not influenced solely by their surroundings, and they may also lack definite properties prior to measurement. This is, of course, deeply contrary to our everyday experiences. Blame for this achievement has now been laid squarely on the shoulders of three physicists: John Clauser, Alain Aspect and Anton Zeilinger. The journey from fringe to favor was a long one. Today quantum information science is among the most vibrant subfields in all of physics. For Whom the Bell Tolls. Physicists Create a Wormhole Using a Quantum Computer. Back at Harvard, he and Ping Gao, his graduate student at the time, and Aron Wall, then a visiting researcher, eventually calculated that, indeed, by coupling two sets of entangled particles, you can perform an operation on the left-hand set that, in the dual, higher-dimensional space-time picture, holds open the wormhole leading to the right-hand mouth and pushes a qubit through.

Jafferis, Gao and Wall’s 2016 discovery of this holographic, traversable wormhole gave researchers a new window into the mechanics of holography. “The fact that if you do the right things from the outside you can end up getting through, it also means you can see inside” the wormhole, Jafferis said. “It means that it’s possible to probe this fact that two entangled systems get described by some connected geometry.” The SYK model, as it’s called, is a system of matter particles that interact in groups, rather than the usual pairs. Galaxy formation simulated without dark matter. For the first time, researchers from the Universities of Bonn and Strasbourg have simulated the formation of galaxies in a universe without dark matter. To replicate this process on the computer, they have instead modified Newton's laws of gravity. The galaxies that were created in the computer calculations are similar to those we actually see today.

According to the scientists, their assumptions could solve many mysteries of modern cosmology. The results are published in the Astrophysical Journal. Cosmologists today assume that matter was not distributed entirely evenly after the Big Bang. An important ingredient of this theory is the so-called dark matter. However, there is still no direct proof of its existence. Results close to reality "In cooperation with Dr. The scientists then used this software to simulate the formation of stars and galaxies, starting from a gas cloud several hundred thousand years after the Big Bang.

More than a century after Ernest Rutherford discovered the positively charged particle at the heart of every atom, physicists are still struggling to fully understand the proton. High school physics teachers describe them as featureless balls with one unit each of positive electric charge — the perfect foils for the negatively charged electrons that buzz around them. College students learn that the ball is actually a bundle of three elementary particles called quarks.

But decades of research have revealed a deeper truth, one that’s too bizarre to fully capture with words or images. “This is the most complicated thing that you could possibly imagine,” said Mike Williams, a physicist at the Massachusetts Institute of Technology. “In fact, you can’t even imagine how complicated it is.” The proton is a quantum mechanical object that exists as a haze of probabilities until an experiment forces it to take a concrete form.

As the pursuit continues, the proton’s secrets keep tumbling out. Anti-gravity Effect? Gravitational Equivalent Of A Magnetic Field Measured In Lab -- ScienceDaily. Scientists funded by the European Space Agency have measured the gravitational equivalent of a magnetic field for the first time in a laboratory. Under certain special conditions the effect is much larger than expected from general relativity and could help physicists to make a significant step towards the long-sought-after quantum theory of gravity. Just as a moving electrical charge creates a magnetic field, so a moving mass generates a gravitomagnetic field. According to Einstein's Theory of General Relativity, the effect is virtually negligible. However, Martin Tajmar, ARC Seibersdorf Research GmbH, Austria; Clovis de Matos, ESA-HQ, Paris; and colleagues have measured the effect in a laboratory.

Their experiment involves a ring of superconducting material rotating up to 6 500 times a minute. Superconductors are special materials that lose all electrical resistance at a certain temperature. New Mind-blowing Experiment Confirms That Reality Doesn’t Exist If You Are Not Looking at It · The Mind Unleashed. According to a well-known theory in quantum physics, a particle’s behavior changes depending on whether there is an observer or not. It basically suggests that reality is a kind of illusion and exists only when we are looking at it. Numerous quantum experiments were conducted in the past and showed that this indeed might be the case. Now, physicists at the Australian National University have found further evidence for the illusory nature of reality. They recreated the John Wheeler’s delayed-choice experiment and confirmed that reality doesn’t exist until it is measured, at least on the atomic scale.

Thought-provoking findings Some particles, such as photons or electrons, can behave both as particles and as waves. The results of the Australian scientists’ experiment, which were published in the journal Nature Physics, show that this choice is determined by the way the object is measured, which is in accordance with what quantum theory predicts. “It proves that measurement is everything.

Gravitational Equivalent Of A Magnetic Field Measured In Lab -- ScienceDaily. Strange Behavior Of Quantum Particles May Indicate The Existence Of Other Parallel Universes. By John Davis | Phys.org It started about five years ago with a practical chemistry question. Little did Bill Poirier realize as he delved into the quantum mechanics of complex molecules that he would fall down the rabbit hole to discover evidence of other parallel worlds that might well be poking through into our own, showing up at the quantum level.

The Texas Tech University professor of chemistry and biochemistry said that quantum mechanics is a strange realm of reality. Particles at this atomic and subatomic level can appear to be in two places at once. Chemists like Poirier draw these landscapes to better understand chemical reactions. Though his theory, called “Many Interacting Worlds,” sounds like science fiction, it holds up mathematically. Originally published in 2010, it has led to a number of invited presentations, peer-reviewed journal articles and a recent invited commentary in the premier physics journal Physical Review.

There is no fuzziness in his theory. Waving goodbye? 1604.02589v2. Spooky Quantum Camera Can Snap Photos of ‘Ghosts’ By Alexa Erickson | Conscious Evolution People have mixed opinions about ghosts. Some only think of them as the stuff of movies and books, movies and books, while others believe they can feel them, have seen them, and that they need to be recognized as real, not imaginary. Now, a process Einstein famously referred to as “spooky” is allowing scientists to catch “ghosts” on film for the first time thanks to the use of quantum cameras.

But let’s be clear: These figures aren’t wandering souls or lingering ancestors. Rather, they are the images of objects from photons that never even experienced the objects pictured. A normal digital camera is capable of capturing objects that aren’t immediately visible to its lens. But the ghost imaging technique, which shoots an image of an object from light without light ever bouncing off the object, is the result of quantum entanglement. Quantum cameras snap ghost images by using two separate laser beams with their photons entangled. Time Travel Proven Possible by Physicists Sending Photons Into 'The Past' The study of closed timelike curves (CTC’s) provides valuable insight into particles that can loop back on themselves, breaking free of linear time. “One aspect of general relativity that has long intrigued physicists is the relative ease with which one can find solutions to Einstein’s field equations that contain closed timelike curves (CTCs)—causal loops in space–time that return to the same point in space and time.”

(source) The Science Closed timelike curves are a necessary concept to understand this experiment. CTCs are used to simulate powerful gravitational fields, like the ones produced by a spinning black hole, that could theoretically (based on Einstein’s theory of general relativity), warp the fabric of existence so that space-time bends back on itself. The source of time travel speculation lies in the fact that our best physical theories seem to contain no prohibitions on traveling backward through time. Experimenting With CTC’s The Grandfather Paradox in Quantum Physics. Untitled. Physicists Send Particles Of Light Into The Past, Proving Time Travel Is Possible?

Scientists from the University of Queensland, Australia, have used single particles of light (photons) to simulate quantum particles travelling through time. They showed that one photon can pass through a wormhole and then interact with its older self. Their findings were published in Nature Communications. The source of this time travel conundrum comes from what are called “closed timelike curves” (CTC). CTCs are used to simulate extremely powerful gravitational fields, like the ones produced by a spinning black hole, and could, theoretically (based on Einstein’s theory of general relativity), warp the fabric of existence so that spacetime bends back on itself – thus creating a CTC, almost like a path that could be used to travel back in time.

According to Scientific American, many physicists find CTCs “abhorrent, because any macroscopic object traveling through one would inevitably create paradoxes where cause and effect break down.” The Experiment Why This Is A High Probability. Tensor–vector–scalar gravity. Tensor–vector–scalar gravity (TeVeS),[1] developed by Jacob Bekenstein in 2004, is a relativistic generalization of Mordehai Milgrom's Modified Newtonian dynamics (MOND) paradigm.[2] [3] The main features of TeVeS can be summarized as follows: As it is derived from the action principle, TeVeS respects conservation laws;In the weak-field approximation of the spherically symmetric, static solution, TeVeS reproduces the MOND acceleration formula;TeVeS avoids the problems of earlier attempts to generalize MOND, such as superluminal propagation;As it is a relativistic theory it can accommodate gravitational lensing.

The theory is based on the following ingredients: These components are combined into a relativistic Lagrangian density, which forms the basis of TeVeS theory. Details[edit] MOND[2] is a phenomenological modification of the Newtonian acceleration law. In Newtonian gravity theory, the gravitational acceleration in the spherically symmetric, static field of a point mass at distance where is. Physicists To Put One Large Physical Object In Two Places At The Same Time. A pair of scientists — Dr. Yin of Bejing’s Tsinghua University and Dr. Li of Indiana’s Perdue University — have proposed what they believe to be a plausible method of observing a living organism in two places at once. (source) According to Dr. Li: Although it has attracted enormous interest, no quantum superposition state of an organism has been realized. So we propose a straightforward approach to put a microbe into a superposition of two spatial states, that is, the microbe will be at two different positions at the same time … It will be the first experiment to put an organism into a quantum superposition state.

While this type of speculation is usually, and automatically, chucked into the ‘fairy tale’ bin, the possibility of one solid piece of matter (anything that has mass) existing in multiple places at once is quite real and has, at the subatomic microscopic (quantum) level, already been demonstrated. It kind of makes you wonder, are there multiple dimensions?
