The free-energy principle: Can one idea explain why everything exists?

What life is and how the mind works fall within the compass of one bold concept. But critics say that by attempting to explain everything, it may end up explaining nothing

The physicist searching for quantum gravity in gravitational rainbows

Claudia de Rham thinks that gravitons, hypothetical particles thought to carry gravity, have mass. If she’s right, we can expect to see “rainbows” in ripples in space-time

Peter Higgs, physicist who theorised the Higgs boson, has died aged 94

Nobel prizewinning theoretical physicist Peter Higgs has died aged 94. He proposed the particle that gives other particles mass – now named the Higgs boson and discovered by the Large Hadron Collider at CERN in 2012




hi

How Peter Higgs revealed the forces that hold the universe together

The physicist Peter Higgs quietly revolutionised quantum field theory, then lived long enough to see the discovery of the Higgs boson he theorised. Despite receiving a Nobel prize, he remained in some ways as elusive as the particle that shares his name

Bizarre crystal made only of electrons revealed in astonishing detail

To capture the clearest and most direct images of a “Wigner crystal”, a structure made entirely of electrons, researchers used a special kind of microscope and two pieces of graphene unusually free of imperfections

Single atoms captured morphing into quantum waves in startling image

In the 1920s, Erwin Schrödinger wrote an equation that predicts how particles-turned-waves should behave. Now, researchers are perfectly recreating those predictions in the lab




hi

The galactic anomalies hinting dark matter is weirder than we thought

Cosmological puzzles are tempting astronomers to rethink our simple picture of the universe – and ask whether dark matter is even stranger than we thought




hi

Why we are finally within reach of a room-temperature superconductor

A practical superconductor would transform the efficiency of electronics. After decades of hunting, several key breakthroughs are inching us very close to this coveted prize

Quantum ‘super behaviour’ could create energy seemingly from nothing

It should be possible to combine several quantum states, each with almost no energy, to create a single quantum state containing unexpectedly energy-rich regions




hi

Is it possible to fully understand the universe while living in it?

Through science, we are striving for objective knowledge about the universe around us. But physicists increasingly believe achieving this will never be possible

hi

New spin on quantum theory forces rethink of a fundamental physics law

In the quantum realm, a particle’s properties can be separate from the particle itself, including its angular momentum – which could require a rethinking of fundamental laws




hi

The odds of quantum weirdness being real just got a lot higher

An experiment to test distant particles’ ability to correlate their behaviour is one of the strongest pieces of evidence that classical ideas about reality are incorrect




hi

This antimatter version of an atomic nucleus is the heaviest yet

Smashing gold nuclei together at high speeds billions of times has resulted in 16 particles of antihyperhydrogen-4, a very exotic and heavy form of antimatter

Another blow for dark matter as biggest hunt yet finds nothing

The hunt for particles of dark matter has been stymied once again, with physicists placing constraints on this mysterious substance that are 5 times tighter than the previous best




hi

This test could reveal whether gravity is subject to quantum weirdness

If gravity is a truly quantum entity, something as simple as measuring the strength of an object’s gravitational field should change its quantum state




hi

There may be a cosmic speed limit on how fast anything can grow

Alan Turing's theories about computation seem to have a startling consequence, placing hard limits on how fast or slow any physical process in the universe can grow




hi

Heat can flow backwards in a gas so thin its particles never touch

A surprising reversal of our usual understanding of the second law of thermodynamics shows that it may be possible for heat to move in the “wrong” direction, flowing from a cold area to a warm one




hi

Jets of liquid bounce off hot surfaces without ever touching them

Droplets of fluid have been known to hover above a hot surface, but a new experiment suggests the same can happen to tiny jets of liquid too




hi

Launching a huge dust cloud from the moon could ease global warming

Launching a million tonnes of moon dust around Earth could dim sunlight across our planet by 1.8 per cent. This would reduce the global temperature, but whether it would be worth the resources, and the risks involved in such a strategy, are unclear

Earliest evidence of a meteorite hitting Earth found in Australia

Tiny pieces of stone found in a rock formation in Western Australia may be the oldest evidence of a meteorite impact on Earth, dating back nearly 3.5 billion years

Sea level may have been higher than it is now just 6000 years ago

Climate researchers thought that current global average sea levels were the highest in more than 100,000 years, but new models suggest oceans just 6000 years ago may have been higher than at the beginning of the industrial revolution, and possibly even higher than today
