Breathingearth The LHC Disproves the Existence of Ghosts and the Paranormal In Brief Renowned physicist Brian Cox has claimed that the lack of any physical evidence being detected by the highly sensitive Large Hadron Collider disproves the existence of ghosts.Four in 10 Americans reportedly believe in ghosts, a figure that belies the lack of scientific evidence behind their existence. The LHC Looks like the Ghostbusters have some competition, and it’s renowned physicist and science communicator Brian Cox. But rather than bust some ghosts, it looks like he’s more in the business of destroying the idea of the paranormal entirely. He wasn’t just looking to spread some knowledge to the 4 in 10 Americans who believe in ghosts, though — he was sharing a simple conclusion he has reached by working with the Large Hadron Collider (LHC). The LHC is the largest and most powerful particle accelerator that humanity has ever built. No Evidence, No Ghosts Cox’s point relies heavily on the LHC’s ability to pick up the tiniest bursts of energy found in particle collisions.
Model of Solar System The LHC Just Discovered A New System of Five Particles A Unique Find The Large Hadron Collider (LHC), the latest addition to CERN’s accelerator complex, is the most powerful particle accelerator ever built. It features a 27 kilometer (16 mile) ring made of superconducting magnets and accelerating structures built to boost the energy of particles in the chamber. In the accelerator, two high-energy particle beams are forced to collide from opposite directions at speeds close to the speed of light. The energy densities that are created when these collisions occur cause ordinary matter to melt into its constituent parts—quarks and gluons. It is a project of massive, unparalleled proportions. More than 10,000 scientists and engineers are currently working together to help us learn about the fundamental properties of physics using the LHC. And today, a paper proved that these discoveries aren’t slowing down. Excitement Abounds Each of the five particles were found to be excited states of Omega-c-zero, a particle with three quarks.
Finding faster-than-light particles by weighing them In a new paper accepted by the journal Astroparticle Physics, Robert Ehrlich, a recently retired physicist from George Mason University, claims that the neutrino is very likely a tachyon or faster-than-light particle. There have been many such claims, the last being in 2011 when the "OPERA" experiment measured the speed of neutrinos and claimed they travelled a tiny amount faster than light. However, when their speed was measured again the original result was found to be in error – the result of a loose cable no less. Ehrlich's new claim of faster-than-light neutrinos is based on a much more sensitive method than measuring their speed, namely by finding their mass. Skeptics of tachyons often cite conflicts with relativity theory. Several decades after tachyons were first proposed, and after many fruitless searches for them, three theorists Chodos, Hauser, and Kostelecky suggested in 1985 that they might be hiding in plain sight – specifically that neutrinos are tachyons.
Quantum mechanics - Wikipedia Description of physical properties at the atomic and subatomic scale Quantum mechanics is a fundamental theory in physics that describes the behavior of nature at and below the scale of atoms.[2]: 1.1 It is the foundation of all quantum physics including quantum chemistry, quantum field theory, quantum technology, and quantum information science. Classical physics, the collection of theories that existed before the advent of quantum mechanics, describes many aspects of nature at an ordinary (macroscopic) scale, but is not sufficient for describing them at small (atomic and subatomic) scales. Quantum mechanics arose gradually from theories to explain observations that could not be reconciled with classical physics, such as Max Planck's solution in 1900 to the black-body radiation problem, and the correspondence between energy and frequency in Albert Einstein's 1905 paper, which explained the photoelectric effect.

The Phenomenon Of Light Generation Through The Crushing Of Materials Is Called? Answer: Triboluminescence The word might sound rather scientific, and maybe a little alien in nature (“triboluminescence” does sound a whole lot like a problem the crew of the Enterprise might run into, after all), but it’s a down-to-Earth phenomenon you may have even experienced yourself. Triboluminescence is light created when crushing, tearing, or other mechanical action triggers the breakdown of chemical bonds in a material (or when peeling adhesive tapes). A popular classroom demonstration of this phenomenon, for example, is to give students rolls of Wint-O-Green Mint Lifesaver candies, enter a darkened room, and then have the students—much to their delight—throw tons of the candies into their mouths and chomp on them vigorously with their mouths open. Human fascination with the phenomenon isn’t thanks to recent scientific discovery, however. Image courtesy of H.
Better Nuclear Power Through Ping Pong The lab is deep-space quiet. A long, narrow hallway hung with fluorescent lights extends to my left. Four or five doors interrupt the flow of drywall. A few of those doors are open, the occupants of the rooms within now out in the hall and staring, ears plugged in anticipation. A technician flips a small lever to activate the vacuum pumps on an 18-foot cannon that is tented in bulletproof polycarbonate.

Conventional reactors use designs that remain basically unchanged since the 1950s. That's the secret to breaking the sound barrier with a ping pong ball: If any air were left in front of the ball, it would crush the ball under the force of the acceleration. What does any of that have to do with ping pong? Two Types of Nuclear Reactions Slow U-235 is the enriched uranium isotope. Fast
'We Don't Planet' Episode 3: What's Up with Gravitational Lensing? The fundamental description of gravity under general relativity — that the presence of matter and energy deforms the fabric of space-time, and this deformation influences the motion of other objects — leads to a rather unexpected result: a massive object can act like a lens, magnifying and warping the images of background objects. This prediction was the first major test of general relativity, with Sir Arthur Eddington leading an expedition to measure the small (but detectable) deflection of starlight around our sun, and today this facet of our universe is used as a powerful cosmological probe. The challenge that gravitational lensing answers is the determination of mass at very large scales. We can even go one step further: by combining multiple lensed images in and around a massive object, we can probe the interior distribution of matter. "We Don’t Planet" is hosted by Ohio State University astrophysicist and COSI chief scientist Paul Sutterwith undergraduate student Anna Voelker.
Tesla's Tower of Power • Damn Interesting In 1905, a team of construction workers in the small village of Shoreham, New York labored to erect a truly extraordinary structure. Over a period of several years the men had managed to assemble the framework and wiring for the 187-foot-tall Wardenclyffe Tower, in spite of severe budget shortfalls and a few engineering snags. The project was overseen by its designer, the eccentric-yet-ingenious inventor Nikola Tesla (10 July 1856 – 7 January 1943). Atop his tower was perched a fifty-five ton dome of conductive metals, and beneath it stretched an iron root system that penetrated more than 300 feet into the Earth’s crust. Though it was far from completion, it was rumored to have been tested on several occasions, with spectacular, crowd-pleasing results. Tesla’s inventions had already changed the world on several occasions, most notably when he developed modern alternating current technology. In 1900, famed financier J.P.
Could cold spot in the sky be a bruise from a collision with a parallel universe? Scientists have long tried to explain the origin of a mysterious, large and anomalously cold region of the sky. In 2015, they came close to figuring it out as a study showed it to be a “supervoid” in which the density of galaxies is much lower than it is in the rest of the universe. However, other studies haven’t managed to replicate the result. Now new research led by Durham University, submitted for publication in the Monthly Notices of the Royal Astronomical Society, suggests the supervoid theory doesn’t hold up. Intriguingly, that leaves open a pretty wild possibility – the cold spot might be the evidence of a collision with a parallel universe. But before you get too excited, let’s look at how likely that would actually be. The cold spot can be seen in maps of the “cosmic microwave background” (CMB), which is the radiation left over from the birth of the universe. However the cold spot is harder to work out. The power of galaxy data So what caused it? Controversial interpretation
Schrödinger’s Cat: Explained Erwin Schrödinger was born in Vienna on August 12, 1887 and was awarded the Nobel Prize in Physics in 1933. He is best known for his work regarding quantum theory, particularly about his thought experiment involving a cat in order to explain the flawed interpretation of quantum superposition. The Copenhagen Interpretation of quantum mechanics essentially states that an object in a physical system can simultaneously exist in all possible configurations, but observing the system forces the system to collapse and forces the object into just one of those possible states. Schrödinger disagreed with this interpretation. So what does this have to do with cats? Schrödinger wanted people to imagine that a cat, poison, a geiger counter, radioactive material, and a hammer were inside of a sealed container. Of course, Schrödinger claimed, that was ridiculous. This video from Sixty Symbols does an excellent job at explaining the Shrödinger’s Cat Paradox:
Emdrive - Theory - Principle of Operation Theory Theory Paper (.pdf) Principle of Operation At first sight the idea of propulsion without propellant seems impossible. However the technology is firmly anchored in the basic laws of physics and following an extensive review process, no transgressions of these laws have been identified. The principle of operation is based on the well-known phenomenon of radiation pressure. If the same EM wave is travelling at a fraction of the speed of light, the rate of change of momentum, and hence force, is reduced by that fraction. Thus if the EM wave travelling in a tapered waveguide is bounced between two reflectors, with a large velocity difference at the reflector surfaces, the force difference will give a resultant thrust to the waveguide linking the two reflectors. Fig 1. The inevitable objection raised, is that the apparently closed system produced by this arrangement cannot result in an output force, but will merely produce strain within the waveguide walls.
