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."

I'd be more up for beating time-dilation and allowing for faster travel through space over time travel.

We use the physics we have, not the physics we *wish* we had.

Neutrinos continue run of odd behavior at Daya Bay
Results could hint at errors, sterile neutrinos, or something even stranger.

Late last week, the Daya Bay experiment in China released a new set of measurements of the neutrinos produced by the nuclear reactors on the site. The new data provides further examples of these strange particles refusing to act like we'd expect them to. This evidence further supports strange behavior that some have interpreted as evidence of the existence of particles beyond the Standard Model, but the new data doesn't bring evidence up to the level of significance required to announce discovery.

For good measure, there's also evidence of an entirely different anomaly—one that could be anything from an indication of new physics to a sign that our experiments were fundamentally misguided.
Neutrinos continue run of odd behavior at Daya Bay @ Ars Technica


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."

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."

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.""

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."

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."

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."

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."
