Gravitational waves from black holes detected

Scientists are claiming a stunning discovery in their quest to fully understand gravity. They have observed the warping of space-time generated by the collision of two black holes more than a billion light-years from Earth. The international team says the … Continue reading

How are scientists able to observe a single atom?

A “quantum microscope” sounds like an impossible device developed by some brilliant but possibly insane scientist who is working on a secret government project to inspect recently-discovered infinitesimal evidence from a decades-old conspiracy. Putting the science fiction aside, though, in … Continue reading

Here’s why our most irrational decisions could be a result of quantum theory

New research looking at the relationship between human decision-making and mathematics has turned up a surprising finding: our most irrational choices might be explained by the theories of quantum mechanics. The idea is that the choices we face are all … Continue reading

Physicists figure out how to make ‘molecules’ of pure light

Physicists have just gotten us a little closer to the dream of building objects out of pure light – hello, lightsabers – by figuring out how to join weightless light particles together to form a kind of ‘two-atom molecule’ with … Continue reading

Quantum spookiness has been confirmed by first loophole-free experiment

Physicists have confirmed that distant particles really can influence each other and act in strange ways that can’t be explained by common sense or, for the most part, the laws of physics. This bizarre behaviour is what’s known as quantum … Continue reading

The LHC finds evidence of particle activity beyond the Standard Model

This Standard Model has served us pretty well so far, but there are some significant holes, the most glaring being the fact that it doesn’t account for gravity. So for decades physicists have been trying to find physics occurring beyond … Continue reading

What Physics Teachers Get Wrong About Tides!

We all know tides have something to do with gravity from the Moon and Sun, but if gravity affects the motion of all objects equally, then how come oceans have large tides while other bodies of water don’t? It’s because … Continue reading

Scientists explore the origins of energy in chemical reactions using experimental quantum chemistry

One thing that all chemical reactions have in common—whether they are the reactions that take place inside a battery, the metabolic reactions inside a living organism, or the combustion reactions that cause an explosion—is that they all involve some kind … Continue reading

Happy Birthday Erwin

Erwin

It’s the birthday of Erwin Schrödinger, who was born in 1887 in Vienna. Schrödinger studied physics at the University of Vienna. After serving in the Austrian army in World War I, he resumed his career as a physicist — first … Continue reading

Scientists have finally discovered massless particles, and they could revolutionise electronics

After 85 years of searching, researchers have confirmed the existence of a massless particle called the Weyl fermion for the first time ever. With the unique ability to behave as both matter and anti-matter inside a crystal, this strange particle … Continue reading

IceCube

Thanks to Phil Krause for suggesting this post. IceCube is a particle detector at the South Pole that records the interactions of a nearly massless subatomic particle called the neutrino. IceCube searches for neutrinos from the most violent astrophysical sources: … Continue reading

This new metal box could help take physics beyond the Standard Model

Researchers in Germany have created a shield that can cut magnetic fields more than a million-fold, and they’ve used it to create one of the most exciting metal boxes on the planet right now. The 4.1-cubic-metre space has the weakest … Continue reading

Towards the ultimate model of water

Researchers from the National Physical Laboratory (NPL), IBM and the University of Edinburgh have developed the first conceptually simple but broadly applicable model for water. Water is essential to life as we know it; from its unusual density maximum which … Continue reading

The neutron and proton weigh in, theoretically

Adding electromagnetic effects to quantum chromodynamics calculations helps theorists achieve a leap in accuracy. The mass difference between the neutron and proton—about 0.14%—is known experimentally with an impressive precision of 3 parts in 10 million. But calculating that difference from … Continue reading

Wormhole Entanglement and the Firewall Paradox

One hundred years after Albert Einstein developed his general theory of relativity, physicists are still stuck with perhaps the biggest incompatibility problem in the universe. The smoothly warped space-time landscape that Einstein described is like a painting by Salvador Dalí … Continue reading
