Stephen Hawking's final paper bursts the multiverse bubble with a Holographic Universe theory. Renowned physicist Stephen Hawking passed away earlier this year, but his legacy to science will live on.
His final theory on the origin of the universe has now been published, and it offers an interesting departure from earlier ideas about the nature of the "multiverse. " Ideas about how the universe came to exist the way we see it today have been adapted and built on for decades. The new paper, authored by Hawking and Professor Thomas Hertog, adds to the literature with a new understanding of a theory known as eternal inflation. After the Big Bang kickstarted the universe, it expanded exponentially for a brief fraction of a fraction of a second. "Holy Grail" Particle: New Physics Research Shows Tetraquarks Must Exist. Quark Quirks Called Tetraquarks Everything in the universe is made up of atoms — except, of course, atoms themselves.
They’re made up of subatomic particles, namely, protons, neutrons, and electrons. Everything We Know About Physics in One Neat Map. Space is big.
Really big. You just won't believe how vastly, hugely, mindbogglingly big it is. On Flipboard. EPR Paradox in Physics - Definition and Explanation. EPR Paradox Definition The EPR Paradox (or the Einstein-Podolsky-Rosen Paradox) is a thought experiment intended to demonstrate an inherent paradox in the early formulations of quantum theory.
It is among the best-known examples of quantum entanglement. The paradox involves two particles which are entangled with each other according to quantum mechanics. Under the Copenhagen interpretation of quantum mechanics, each particle is individually in an uncertain state until it is measured, at which point the state of that particle becomes certain. At that exact same moment, the other particle's state also becomes certain.
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.
The universe might be like a restaurant with 10 menu items, Friedman said. Quantum teleportation over 7 kilometres of cables smashes record. BrettA/Getty By Anil Ananthaswamy A new world record for quantum teleportation has been set, bringing quantum communication networks that can stretch between cities a step closer.
Two independent teams have transferred quantum information over several kilometres of fibre optic networks. 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. It has been shown that even if two uncorrelated quantum systems that don’t know anything about each other can still become entangled in a quantum vacuum without being limited by the speed of light.
Quantum theory states that the quantum vacuum isn’t really empty. 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. 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.

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.
This latent subatomic world of potentiality is the subject for artist Marios Athanasiou's virtual reality project Proto Ether Fields. 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. This new achievement could one day be applied to enable more sensitive magnetic resonance imaging (MRI) scans, superpowerful quantum computers and even unhackable quantum communications networks unhackable by any known current technologies, researchers say.
A fuzzy place Quantum physics explains how all known particles behave. 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. Dark matter, is believed to be an invisible substance making up approximately 27% of all matter and energy of the universe.
Regular matter, or 'visible' builds up only 5% of the universe. According to experts, the rest of the universe building blocks is made of dark energy which is associated with acceleration of our expanding universe.
