An Ultra-Precise Clock Shows How to Link the Quantum World With Gravity
Time was found to flow differently between the top and bottom of a single cloud of atoms. Physicists hope that such a system will one day help them combine quantum mechanics and Einstein’s theory of gravity. […]
Can just one equation describe the entire history of the universe?
As the first Friedmann equation celebrates its 99th anniversary, it remains the one equation to describe our entire universe. […]
Los microplásticos atmosféricos también influyen en el clima
Al igual que otros aerosoles, estas diminutas partículas reflejan y absorben la radiación solar, lo que repercute en la temperatura del planeta. […]
Physicists Created a Supernova Reaction on Earth Using a Radioactive Beam
For the first time, physicists have been able to directly measure one of the ways exploding stars forge the heaviest elements in the Universe. […]
A Hint of Dark Matter Sends Physicists Looking to the Skies
After a search of neutron stars finds preliminary evidence for hypothetical dark matter particles called axions, astrophysicists are devising new ways to spot them. […]
La medición más precisa hasta la fecha de la vida media del neutrón
El experimento UCNτ ha medido con más precisión que nunca el tiempo que tarda un neutrón libre en desintegrarse. Sin embargo, el nuevo resultado sigue sin coincidir con el obtenido mediante una técnica alternativa. […]
New physics: latest results from Cern further boost tantalising evidence
The Large Hadron Collider (LHC) sparked worldwide excitement in March as particle physicists reported tantalising evidence for new physics – potentially a new force of nature. Now, our new result, yet to be peer reviewed, from Cern’s gargantuan particle collider […]
¿Por qué no se dispersan las gotas de agua cuando están en una nube?
Hay una serie de procesos físicos en la atmósfera que favorecen la formación de nubes y otros que favorecen su dispersión […]
A ‘Black Hole Laser’ Could Finally Shine a Light on Elusive Hawking Radiation
Scientists are getting closer to being able to spot Hawking radiation – that elusive thermal radiation thought to be produced by a black hole’s event horizon. Just understanding the concept of this radiation is tricky though, let alone finding it. […]
Mathematicians Prove Melting Ice Stays Smooth
After decades of effort, mathematicians now have a complete understanding of the complicated equations that model the motion of free boundaries, like the one between ice and water. […]
