Nothing is stronger than quantum connections – and now we know why
The mathematics of graphs has helped reveal a principle that limits the strength of quantum correlations – and explains why physicists have never measured any stronger connections in some post-quantum realm

Ultra-secure quantum data sent over existing internet cables
Two commercial telecommunications facilities have been connected by a secure quantum network that used existing fibre optic cables at room temperature – a key step towards a feasible quantum internet

LHC breaks the record for heaviest antimatter nucleus ever seen
Researchers at the Large Hadron Collider found evidence of an unprecedentedly heavy and exotic form of antimatter in the aftermath of a collision between extremely fast lead ions

Why physicists keep trying to get rid of space-time entirely
Physicists are trying to ditch the concept of space-time – the supposed fabric of physical reality. Quantum columnist Karmela Padavic-Callaghan explains why

The 'impossible' particle hinting at the universe's biggest secrets
Neutrinos have always been hard to explain – and now the detection of one so energetic it shouldn't exist may help illuminate the strangest corners of the cosmos

First ever 'black hole bomb' created in the lab
A black hole bomb – an idea first proposed in 1969 – has now been realised in the lab as a toy model made from a rotating cylinder and magnetic coils. Studying the bomb could help us better understand real black holes.

Five physicists discuss the achievements and future of quantum theory
A century since Werner Heisenberg changed the course of physics, five of the world's leading physicists examine the greatest achievements of quantum mechanics and look forward to the next 100 years, in which experiments might finally answer some of the theory's biggest mysteries: is gravity quantum? Can classical and quantum physics be unified? And where …

Liquid physics: Inside the lab making black hole analogues on Earth
Inside Silke Weinfurtner's laboratory at the University of Nottingham in the UK, a giant water tank is helping her team better understand the complexity of the universe by standing in as an analogue for black holes. By introducing waves into a liquid and creating a vortex at the centre, the team mimics some of the …

How dark energy findings may inspire a new generation of physics nerds
The discovery of the cosmic acceleration problem truly inspired me as a teenage physics nerd. Recent, related revelations about dark energy will hopefully capture the interest of today’s young science geeks, says Chanda Prescod-Weinstein

Physicists reveal the secret to chopping onions without crying
Slicing an onion releases tear-inducing chemicals into the air, but the sharpness of the knife and the speed of the cut can affect how these droplets are expelled

The bold attempt to solve the toughest mystery at the heart of physics
Finding out whether gravity – and therefore space-time itself – is quantum in nature has long been thought impossible. But innovative new ideas might be about to help answer this crucial question

'Dark photon' theory of light aims to tear up a century of physics
One of the most famous findings in physics could be wrong – the double-slit experiment was long thought to confirm that light can be a wave, but its results can be fully explained using only quantum particles

Where exactly does the quantum world end and concrete reality begin?
Quantum effects like superposition and entanglement have long been seen in single particles, but physicists are on a quest to find out just how big an object can be before it loses its quantumness

Quantum theory at 100: Let’s celebrate its power and provocation
Quantum theory started with a bout of hay fever, and went on to transform our view of the universe – but its legacy isn't complete
