Experiment With Chinese Satellite Demonstrates Quantum Weirdness Over Record Distances

Quantum mechanics is weird as hell, where the rules of the world you experience don’t apply. Even at distances a thousand kilometres apart, particles seem to be able to communicate with each other. Read More >>

Scientists Finally Observed Time Crystals—But What the Hell Are They?

This Book is a Breathtaking Introduction to the Nature of Reality

A fabric that bends and ripples under the weight of the stars. A clock that runs slower perched high in the mountains. Objects that only exist when they’re being watched. Endless tiny particles, swarming restlessly in the void. Read More >>

Physicists Prove That ‘Spooky Action at a Distance’ is Real

Entanglement is one of the strangest aspects of quantum mechanics, whereby two subatomic particles can be so closely connected that one can seem to influence the other even across long distances. Albert Einstein dubbed it “spooky action at a distance,” and two new experiments have now definitively shown that the phenomenon is real. Read More >>

A New Way of Thinking About Spacetime That Turns Everything Inside Out

One of the weirdest aspects of quantum mechanisms is entanglement, because two entangled particles affecting each other across vast distances seems to violate a fundamental principle of physics called locality: things that happen at a particular point in space can only influence the points closest to it. But what if locality — and space itself — is not so fundamental after all? Author George Musser explores the implications in his new book, 'Spooky Action At a Distance'. Read More >>

Did We Really See Light Acting as a Particle and a Wave at Once?

Several weeks ago, the internet lit up with the colourful image shown above and in full below, accompanied by headlines claiming that physicists had accomplished the extraordinary: we'd finally managed to see light as both a particle and a wave at the same time. But...this isn't exactly true. Read More >>

Five Reasons Why Our Universe Might Actually be a Virtual Reality

Physical realism is the view that the physical world we see is real and exists by itself, alone. Most people think this is self-evident, but physical realism has been struggling with the facts of physics for some time now. The paradoxes that baffled physics last century still baffle it today, and its great hopes of string theory and supersymmetry aren't leading anywhere. Read More >>

Scientists are Going to Create the Coldest Spot in the Known Universe

The universe is freezing. In spots like the Boomerang Nebula the temperature drops all the way down to one degree Kelvin. But if NASA scientists have their way, the known universe will have a new coldest place, and it's going to be inside the International Space Station. Read More >>

Why Programming a Quantum Computer Is So Damn Hard

Someday, somehow, quantum computing is going to change the world as we know it. Even the lamest quantum computer is orders of magnitude more powerful than anything we could ever make today. But figuring out how to program one is ridiculously hard. Read More >>

Photons Can Communicate From Beyond the Grave

Everyone knows that quantum physics is weird—but it just got weirder. Because a team of scientists from the University of Jerusalem have used quantum entanglement to allow two photons that never existed at the same time to communicate with each other. Read More >>

Quantum Physics Can Make an Unjammable Radar

Radar has been the way to spot enemy aircraft zooming across the sky for decades, but (un)fortunately, it doesn't always work. If you've got the right tech, you can fool it. A new kind developed by researchers at the University of Rochester however, dips into quantum physics and is unjammable and infallible. Read More >>

Scientists Just Discovered the Speed Limit for Quantum Particles

Nothing travels faster than light in a vacuum, obviously. And while scientists knew that quantum particles interact with one another at a slower speed, they had trouble measuring the speed at which that happens. Until now, that is. Read More >>
