Rethinking reality: Is the entire universe a single quantum object?
In the face of new evidence, physicists are starting to view the cosmos not as made up of disparate layers, but as a quantum whole linked by entanglement

Lights could be the future of the internet and data transmission
A new study led by the University of Surrey and University of Cambridge has investigated how to release high-speed photonic sources using metal-halide perovskites. These are semiconductors being researched with LEDs for their excellent optoelectronic properties and low-cost processing methods.

Physics-Defying Quasiparticles Could Open a Whole New World of Microscopy
To pry into the private lives of objects in the microscopic domain (and beyond), scientists often rely on extremely bright sources of light.

Particle accelerator on a chip
Particle accelerators are crucial tools in a wide variety of areas in industry, research and the medical sector. The space these machines require ranges from a few square meters to large research centers. Using lasers to accelerate electrons within a photonic nanostructure constitutes a microscopic alternative with the potential of generating significantly lower costs and making devices considerably less bulky. Until now, no substantial energy gains were demonstrated. In other words, it has not been shown that electrons really have increased in speed significantly. Two teams of laser physicists have just succeeded in demonstrating a...

Physicists Discover Surprising Quantum-Like Behavior in Tiny Bouncing Droplets
Quantum physics is fundamentally weird, so much so that we need thought experiments of hidden cats in boxes and metaphors of spinning coins to even begin to comprehend its laws.

Quantum Experiment Shows How Time ‘Emerges’ from Entanglement
Time is an emergent phenomenon that is a side effect of quantum entanglement, say physicists. And they have the first experimental results to prove it

Student Finds Way to Boost Conductivity 400x Totally by Accident
Like a modern Henri Becquerel, Washington State University doctoral student Marianne Tarun's discovery came quite by accident. Her simple lab error has uncovered a new way to boost electrical conductivity of a crystal by 40,000 percent, simply by exposing it to light.

Peter Higgs: I wouldn't be productive enough for today's academic system
Peter Higgs, the British physicist who gave his name to the Higgs boson, believes no university would employ him in today's academic system because he would not be considered "productive" enough.

Universe might implode sooner than thought
The Universe is not immortal. Eventually, it will either expand to the point of heat death, or it'll collapse. Either of these will likely take a very, very, very long time to happen, but a group of scientists from the University of Southern Denmark now believe that a collapse is more likely, and that we might have to knock off one of those "very"s from how long we've got. Yes, we’re all doomed.

All the Universe Is ... Just a Hologram?
Prepare for a head trip: The universe may actually be a hologram and everything you see an illusion, according to new research that could prove gravity comes from thin, vibrating strings—holograms.

Universe May Have Been Around Since Forever, According to Rainbow Gravity Theory
When did the clock of the universe start ticking? For decades we’ve believed that 13.8 billion years ago the Big Bang set the universe’s clock in motion. While that’s still the prevailing viewpoint, researchers are now exploring a theory called “rainbow gravity” that, if correct, does away with the Big Bang. In a “rainbow” universe, the clock has been ticking forever.

A Thin Sheet of Reality: The Universe as a Hologram
What we touch. What we smell. What we feel. They’re all part of our reality. But what if life as we know it reflects only one side of the full story? Some of the world’s leading physicists think that this may be the case. They believe that our reality is a projection—sort of like a hologram—of laws and processes that exist on a thin surface surrounding us at the edge of the universe.
