Theory explaining Electromagnetic energy without
radiation could be important physics breakthrough: "Physicists have found a radical new way confine electromagnetic energy without it leaking away, akin to throwing a pebble into a pond with no splash The theory could have broad ranging applications from explaining dark matter to combating energy losses in future technologies. However, it appears to contradict a fundamental tenet of electrodynamics, that accelerated charges create electromagnetic radiation, said lead researcher Dr Andrey Miroshnichenko from The Australian National University (ANU). "This problem has puzzled many people. It took us a year to get this concept clear in our heads," said Dr Miroshnichenko, from the ANU Research School of Physics and Engineering. The fundamental new theory could be used in quantum computers, lead to new laser technology and may even hold the key to understanding how matter itself hangs together."

Einstein's gravitational waves detected in scientific
milestone: "Scientists have for the first time detected gravitational waves, ripples in space and time hypothesized by Albert Einstein a century ago, in a landmark discovery announced on Thursday that opens a new window for studying the cosmos. The researchers said they detected gravitational waves coming from two distant black holes - extraordinarily dense objects whose existence also was foreseen by Einstein - that orbited one another, spiraled inward and smashed together. They said the waves were the product of a collision between two black holes roughly 30 times the mass of the Sun, located 1.3 billion light years from Earth."

Hold Up, Did We Just Crack Time Travel?:
"Astrophysicists famously proved Einstein’s theory on the existence of gravitational waves last week. Here’s the less covered part of it all: It might, down the line, bring us closer to moving through time." See: http://www.thedailybeast.com/article...me-travel.html |

It's very interesting to consider that maybe we have found a bit of "Dark Matter" actually. Or it's just errors in the way we study these particles. Either way science moves forward

New Evidence Could Overthrow the Standard
View of Quantum Mechanics: "The authors of that paper concluded that a particle following the laws of Bohmian mechanics would end up taking a trajectory that was so unphysical—even by the warped standards of quantum theory—that they described it as “surreal.” Nearly a quarter-century later, a group of scientists has carried out an experiment in a Toronto laboratory that aims to test this idea. And if their results, first reported earlier this year, hold up to scrutiny, the Bohmian view of quantum mechanics—less fuzzy but in some ways more strange than the traditional view—may be poised for a comeback."

16 Predictions of quantized inertia where experiments
could validate the predictions and the theory: "Dr. Mike McCulloch, Lecturer in Geomatics, had created a model for inertia called: Modified inertia by a Hubble-scale Casimir effect (MiHsC) or quantized inertia. Nextbigfuture covered it a few months ago. Mike uses it to explain the controversial emDrive." See: http://nextbigfuture.com/2016/05/16-...d-inertia.html |

Particle X could be the biggest physics breakthrough
in decades: "This is by far the most exciting thing that has happened in particle physics over the last three decades. If this hint of new physics is confirmed - something that could happen within just a few weeks, or possibly even within days - it is difficult to state the importance of such a discovery. It would be bigger than the detection of the Higgs boson, which was just confirmation of what was already known. "If the bump is real, we are about to start writing a whole new chapter in the history of fundamental physics. It is impossible to imagine where this could lead."

New theory explains gravity better than Einstein's relativity:
"When it comes to explaining gravity, Einstein's theories of relativity are the gold standard. That doesn't mean they're perfect, however. For instance, in order to account for the large-scale movements of galaxies under Einstein's theories, scientists have had to postulate the existence of dark matter, a mysterious, undetectable substance that purportedly must make up as much as 80 percent of all matter in the universe. But now there's a new theory on the block that's based on the idea that the universe is a hologram, and it doesn't require dark matter or its elusive cousin, dark energy, to explain gravity on a larger scale, reports Phys.org. The idea, proposed by Erik Verlinde, renowned expert in string theory at the University of Amsterdam, is that gravity is not a fundamental force of nature, but instead an emergent phenomenon. This is a subtle but crucial distinction. In the same way, temperature is also not a fundamental force, but rather a phenomenon that arises from the movements of particles."

Space breakthrough: Scientists teleport
photon from Earth to orbit: "In 2010, a team at the University of Science and Technology of China in Shanghai set a record by teleporting photons over 60 miles on Earth. And now, just seven years later, they’ve outdone themselves, teleporting protons from a ground station in Tibet, 2½ miles above sea level, to a satellite orbiting Earth more than 310 miles away. It marks the first time an object has been teleported from our planet into space." See: http://www.foxnews.com/tech/2017/07/...-to-orbit.html |

Quantum mechanical particles travel backwards, study confirms:
"A team of particle physicists and mathematicians have confirmed all quantum mechanical particles move backwards -- in the opposite direction of the force acting upon them. The phenomenon is called "backflow."" See: https://www.upi.com/Science_News/201...5011500383202/ |

Electrons in Graphene can become superballistic
which starts a new wave of physics: "In some high-quality materials, like graphene, electrons can travel micron distances without scattering, improving the conductivity by orders of magnitude. This so-called ballistic regime, imposes the maximum possible conductance for any normal metal, which is defined by the Landauer-Buttiker formalism. Three different experiments, including one performed by The University of Manchester, demonstrated that at certain temperatures, electrons collide with each other so frequently they start to flow collectively like a viscous fluid. N w research demonstrates that this viscous fluid is even more conductive than ballistic electrons. The result is rather counter-intuitive, since typically scattering events act to lower the conductivity of a material, because they inhibit movement within the crystal. However, when electrons collide with each other, they start working together and ease current flow." See: https://www.nextbigfuture.com/2017/0...f-physics.html |

Physicists Want to Rebuild Quantum Theory From Scratch:
"Some physicists just shrug and say we have to live with the fact that quantum mechanics is weird. So particles can be in two places at once, or communicate instantaneously over vast distances? Get over it. After all, the theory works fine. If you want to calculate what experiments will reveal about subatomic particles, atoms, molecules and light, then quantum mechanics succeeds brilliantly. But some researchers want to dig deeper. They want to know why quantum mechanics has the form it does, and they are engaged in an ambitious program to find out. It is called quantum reconstruction, and it amounts to trying to rebuild the theory from scratch based on a few simple principles." See: https://www.wired.com/story/physicis...-from-scratch/ |

Are the Fundamental Constants of the Universe Changing?:
"Everything we know about the universe is based on laws of physics which we assume to be constant and unchanging. But are they? Astrophysicists are looking at the universal constants that underlie the laws of physics to see if they may have changed over the course of the universe's history. Most of these constants, such as the speed of light, are almost impossible to measure for change, because all of our other measurements are based on them. But others, like the lesser known fine structure constant, may be possible to measure for change." See: http://www.popularmechanics.com/spac...ants-changing/ |

Device creates negative mass and a new way to generate lasers:
"Most objects react in predictable ways when force is applied to them—unless they have “negative mass.” And then they react exactly opposite from what you would expect. Now University of Rochester researchers have succeeded in creating particles with negative mass in an atomically thin semiconductor, by causing it to interact with confined light in an optical microcavity."

The Fifth Force of Nature Could Be Real and Fantastic:
"In 2016, Attila Krasznahorkay made news around the world when his team published its discovery of evidence of a fifth force of nature. Now, the scientists are making news again with a second observation of the same force, which may be the beginning of a unified fifth force theory. The researchers have made their original LaTeX paper available prior to acceptance by a peer-reviewed journal. Study of the hypothesized fifth force, a subfield all by itself, is centered on trying to explain missing pieces in our understanding of physics, like dark matter, which could be expanded or validated by an important new discovery or piece of evidence. Scientists and specifically cosmologists are baffled by the amount of our universe made of dark matter and energy we can’t observe except in indirect ways and still don’t understand."

A Meta-Theory of Physics Could Explain Life, the Universe, Computation,
and More: "You may think of physics as a way to explain the behaviors of things like black holes, colliding particles, falling apples, and quantum computers. But a small group physicists today is working on a theory that doesn’t just study individual phenomena; it’s an entirely new way to describe the universe itself. This theory might solve wide-ranging problems such as why biological evolution is possible and how abstract things like ideas and information seem to possess properties that are independent of any physical system. It’s called constructor theory, but as fascinating as it is, there’s one glaring problem: how to test it." See: https://gizmodo.com/a-meta-theory-of...ver-1844806293 |
