Quantum communicating with the Extraterrestrial Intelligence

Humanity is facing now the dawn of a new technological era involving quantum mechanics in almost all aspects of social life, from computation to communication. It might be natural to ask if we shouldn’t consider search for quantum messages from extraterrestrial intelligence. China has launched the first quantum communication satellite last year bringing the humanity…

How scientists created a new state of matter

Some of the most profound predictions in theoretical physics, such as Einstein’s gravitational waves or Higgs’ boson, have taken decades to prove with experiments. But every now and then, a prediction can become established fact in an astonishingly short time. This is what happened with “time crystals”, a new and strange state of matter that…

Quantum Computing and Spacetime Curvature

General Relativity and quantum theory, the two pillars of modern physics, although notoriously difficult to reconcile, may beautifully work together, as a new paper suggests.  Moreover, the spacetime curvature and twisting create, manipulate and communicate quantum information encoded in light. Arguably, the reconciliation of General Relativity and quantum physics is probably the most difficult endeavor…

High-speed electrons so fast, they break current physics models

In the region of space just outside Earth’s magnetic field, NASA has detected electrons that are being accelerated to almost the speed of light – and no one can explain why. In fact, our current understanding of particle physics says this kind of acceleration should be impossible so far out from the magnetosphere, and now…

Tweak solves five of the biggest problems in physics in one go

It’s not a bad day at work. Five of the biggest fundamental problems in physics seem sorted in one go. The model that can do this, formulated by Guillermo Ballesteros at the University of Paris-Saclay in France and his colleagues, may explain dark matter, neutrino oscillations, baryogenesis, inflation and the strong CP problem.

Physicists Create World’s First Time Crystal

Time crystals were first predicted in 2012. Now researchers have created time crystals for the first time and say they could one day be used as quantum memories. Crystals are extraordinary objects, not least because of their symmetry. Crystals form repeating patterns that are the same in some directions but not all directions. That’s something…

Time Might Only Exist in Your Head

In physics, they are all the same thing. But to you, me, and everyone else, time moves in one direction: from expectation, through experience, and into memory. This linearity is called the arrow of time, and some physicists believe it only progresses that way because humans, and other beings with similar neurological wiring, exist to…

Physicists successfully stop light

“Optical quantum computing is still a long way off, but our successful experiment to stop light gets us further along the road,” said lead researcher. Physicists have brought quantum computers – which could solve problems too complex for today’s most advanced machines – a step closer to reality by successfully stopping light in a new…

The secret lives of long-lived particles

  A theoretical species of particle might answer nearly every question about our cosmos—if scientists can find it. The universe is unbalanced. Gravity is tremendously weak. But the weak force, which allows particles to interact and transform, is enormously strong. The mass of the Higgs boson is suspiciously petite. And the catalog of the makeup…

The Evolutionary Argument Against Reality

The cognitive scientist Donald Hoffman uses evolutionary game theory to show that our perceptions of an independent reality must be illusions. As we go about our daily lives, we tend to assume that our perceptions — sights, sounds, textures, tastes — are an accurate portrayal of the real world. Sure, when we stop and think…

New Laser Created from Jellyfish’s Fluorescent Proteins

Fluorescent proteins from jellyfish that were grown in bacteria have been used to create a laser for the first time, according to a new study. The breakthrough represents a major advance in so-called polariton lasers, the researchers said. These lasers have the potential to be far more efficient and compact than conventional ones and could…

The Grandfather Paradox

What would happen to you if you went back in time and killed your grandfather? A model using photons reveals that quantum mechanics can solve the quandary—and even foil quantum cryptography On June 28, 2009, the world-famous physicist Stephen Hawking threw a party at the University of Cambridge, complete with balloons, hors d’oeuvres and iced…
