The Universe Is as Spooky as Einstein Thought - The Atlantic. There might be no getting around what Albert Einstein called “spooky action at a distance.”
With an experiment described this week in Physical Review Letters—a feat that involved harnessing starlight to control measurements of particles shot between buildings in Vienna—some of the world’s leading cosmologists and quantum physicists are closing the door on an intriguing alternative to “quantum entanglement.” “Technically, this experiment is truly impressive,” said Nicolas Gisin, a quantum physicist at the University of Geneva who has studied this loophole around entanglement. According to standard quantum theory, particles have no definite states, only relative probabilities of being one thing or another—at least, until they are measured, when they seem to suddenly roll the dice and jump into formation. In 1964, the Northern Irish physicist John Bell found a way to put this paradoxical notion to the test. Quantum teleportation over 7 kilometres of cables smashes record.

Bigger than the Higgs, bigger even than gravitational waves... Stuart Patience By Matthew Chalmers IF IT is anything, it is what Gian Giudice has been waiting for his entire scientific life.
“We are not talking about a confirmation of an established theory, but about opening a door into an unknown and unexplored world,” says Giudice, a theoretical particle physicist based at CERN near Geneva, Switzerland. Bigger than the Higgs, bigger even than gravitational waves... Quantum Entanglement harvesting in a vacuum. Entanglement is an extremely strong correlation that can exist between quantum systems.
These correlations are so strong that two or more entangled particles have to be described with reference to each other, even though the individual objects may be spatially separated. 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.” 3 Theories About LHC’s Mysterious “New Particle” Explained. If you remember back on December 15, 2015, CERN announced that researchers may have discovered a new particle using the Large Hadron Collider (LHC) — marking the first set of significant results since upgrades were completed at the LHC earlier that year.
What happened was that researchers observed large spikes in energy that could have been the result of particle collisions between a new boson that is even larger than the Higgs Boson. More specifically, the LHC saw unexpected, excess pairs of photons, each carrying 750 gigaelectronvolts (GeV) of energy, as the result of proton-proton collisions. They believe this could have come from the decay of a new 1,500 GeV particle.

According to the ideas of quantum field theory, reality consists of underlying interrelated layers of energy that constantly interact with one another.
From this interconnectivity, "proto-reality" particles are manifested. Physicists Send Particles Of Light Into The Past, Proving Time Travel Is Possible? 'Spooky Action' Heats Up: Atoms Entangled at Room Temperature. The world of the very small can get pretty wacky — particles can be in two or more places at once, and even become entangled, wherein actions on one entity can affect its partners across the cosmos.
Physicists have broken all kinds of records in proving the existence of so-called quantum entanglement, and now, they have done it again, coupling together thousands of atoms at room temperature. Previously, these atoms could be paired only at temperatures cold enough to liquefy helium. Earth surrounded by dense, hairy filaments of dark matter. A new research, conducted by scientists of NASA's Jet Propulsion Laboratory in Pasadena, California, suggests that Earth is surrounded by long, 'hairy' filaments of dark matter.
Theoretically, the hairy filaments, if detected could be used to map out the inner layers of any planet or space bodies, NASA announced on November 23, 2015. Einstein's Unfinished Dream: Marrying Relativity to the Quantum World. Don Lincoln is a senior scientist at the U.S.

In Brief. Relativity v quantum mechanics – the battle for the universe. It is the biggest of problems, it is the smallest of problems. At present physicists have two separate rulebooks explaining how nature works. There is general relativity, which beautifully accounts for gravity and all of the things it dominates: orbiting planets, colliding galaxies, the dynamics of the expanding universe as a whole.
That’s big. Then there is quantum mechanics, which handles the other three forces – electromagnetism and the two nuclear forces. Action at a distance is confirmed to be real and allows for better secure quantum communication. Researchers working at Delft University in The Netherlands, have succeeded in closing the two loopholes that have prevented proving that local realism does not hold at the quantum level. The experiment has remarkable practical value as well, as entanglement allows for a form of secure communication. The measurement outcomes can be used as an encryption key which is fundamentally impossible to eavesdrop on as it doesn’t travel between two points, but is created through the instantaneous entanglement link. At issue is proving that quantum entanglement does not occur due to some strange unexplainable communication factor, or variable as Einstein suggested—a task that has proved exceptionally challenging—so much so that despite nearly a century of trying, no one, until now apparently, has been able to do it.
In this new experiment, led by Ronald Hanson, the researchers set about closing both loopholes, which would theoretically shut the door on local realism.
CERN experiment to test if we can connect to another dimension. In an experiment proposal that sounds more like an evil genius’ plan than a reputable science endeavour, CERN’s LHC atom smasher in Geneva, Switzerland will be cranked up to the highest energy levels ever, as scientists hope to detect or create miniature black holes. If successful, scientists hope that the experiment might uncover extra dimensions hidden in our universe. “Normally, when people think of the multiverse, they think of the many-worlds interpretation of quantum mechanics, where every possibility is actualised. This cannot be tested and so it is philosophy and not science. Entanglement: Gravity's long-distance connection. View the video When Albert Einstein scoffed at a “spooky” long-distance connection between particles, he wasn’t thinking about his general theory of relativity. Einstein’s century-old theory describes how gravity emerges when massive objects warp the fabric of space and time.
Quantum entanglement, the spooky source of Einstein’s dismay, typically concerns tiny particles that contribute insignificantly to gravity. A speck of dust depresses a mattress more than a subatomic particle distorts space. Yet theoretical physicist Mark Van Raamsdonk suspects that entanglement and spacetime are actually linked. Multiple journals rejected his paper. In 2012, another provocative paper presented a paradox about entangled particles inside and outside a black hole. Dark Matter May Be More Complex Than Physicists Thought. Dark matter—the unseen 80 percent of the universe’s mass—doesn’t emit, absorb or reflect light. Jim Al-Khalili: How quantum biology might explain life’s biggest questions. Where Are All the Dark Energy and Dark Matter? Two experiments on Earth are helping to shine light on the hidden characteristics of dark energy and dark matter — elusive phenomena that make up nearly 95 percent of the universe but remain hidden from direct detection.
The new dark matter and dark energy experiments narrowed the realm where the mysterious material can lie, thus helping scientists to better understand the strange stuff that, together, constitutes the majority of the universe. In search of the mysterious "chameleon particle" — a potential source of dark energy — a team of scientists, led by Paul Hamilton, a postdoctoral fellow at the University of California, Berkeley, measured the forces acting on a falling cesium atom. In a separate study, researhers with the Xenon Collaboration of universities investigated how dark matter might interact with the electrons of an atom. Although neither team found the mysterious particle they sought, they were able to better constrain the characteristics of dark energy and dark matter.

Cosmic Mystery Deepens with Discovery of New Ultra-High-Energy Neutrino. LHC Keeps Bruising 'Difficult to Kill' Supersymmetry. CERN’s LHCb experiment reports observation of exotic pentaquark particles and should allow better understanding of matter. The LHCb experiment at CERN’s Large Hadron Collider has reported the discovery of a class of particles known as pentaquarks. The collaboration has submitted a paper reporting these findings to the journal Physical Review Letters.
“The pentaquark is not just any new particle,” said LHCb spokesperson Guy Wilkinson. “It represents a way to aggregate quarks, namely the fundamental constituents of ordinary protons and neutrons, in a pattern that has never been observed before in over fifty years of experimental searches.
