For the first time, scientists have managed to show quantum entanglement – which Einstein famously described as “spooky action at a distance” – happening between macroscopic objects, a major step forward in our understanding of quantum physics.   Quantum entanglement links particles in a way that they instantly affect each other, even over vast distances. On the

Locking up super-secret information with digital encryption has become even more secure with the production of numbers that aren’t just ‘nearly random’, but are truly unpredictable in every sense of the word.   Using the data generated by a three-year-old experiment on quantum entanglement, the US National Institute of Standards and Technology (NIST) recently generated

For the first time, researchers have used diamond to build a solid-state maser that can operate continuously at room temperature. This could burst open the technology for everyday use such as medical imaging and security scanners at airports.   Masers are like the microwave version of lasers. It stands for “microwave amplification by stimulated emission

Theoretically, it should be possible to turn light into matter. In practice, well – “easier said than done” is an understatement. Now, 84 years after the process was first theorised, some researchers reckon they’re going to be able to do it – and they’re about to start the experiment.   It’s called the Breit-Wheeler process,

Albert Einstein and Stephen Hawking were both incredible physicists, wonderful communicators, and inspirations to science lovers the world over.  In a cosmic coincidence, Stephen Hawking passed away this week on March 14 – Einstein’s birthday. But can you tell which of the beautiful minds said these quotes? Take our quiz to find out.   Source

The foundation stone of quantum mechanics doesn’t just describe the behaviour of infinitesimal subatomic particles – it also governs the movement of the largest and most massive objects in the Universe, says a prominent astrophysicist.   Einstein’s theory of general relativity is often considered the reliable lynchpin of physics at the astronomical scale, but planetary

Quantum physics just beat classical physics again. A single quantum particle can send a two-way signal, scientists have discovered – something that’s impossible in classical physics. That means a particle can essentially send messages to itself thanks to the whacky state of uncertainty known as superposition.   Superposition states that one particle can occupy two

Curling is one of the more unusual sports of the Winter Olympics, often drawing comparisons to shuffleboard, but played on ice. A roughly 42-pound curling rock, or stone, is pushed then slides down a sheet of ice, while two players furiously sweep the surface in front of the stone. The sweeping motion heats up the
