John Stewart Bell laid rest to a 30 year argument about hidden variables in quantum mechanics, proving Einstein wrong in the process.
Quantum entanglement looks like the ideal candidate to achieve faster than light communication, but it turns out the universe has other ideas.
Scientists are excited by the discovery that muons are wobbling more than theory predicts. This could all point to the discovery of a new particle.
Does quantum mechanics give an ‘out’ from the determinism of classical physics? Does it restore free will?
An experiment that hoped to find quantised spacetime has so far come up blank. Space is smooth according to recent experiments in the field.
A young physicist and his supervisor have worked out a way time travel might work without creating any of the paradoxes normally associated with it.
NuScale gets US safety approval for its small nuclear reactor. It is however not as small as I first thought.
In an article on Quanta Magazine, four physicists mull over how naughty gravity can be and why we need a new theory to describe it.
Warp drives aren't just the material of science fiction writers. Proper scientists are investigating them too.
How CP violation favours matter over antimatter, thus giving us the matter-dominated universe we see around us.
How getting rid of the law of the excluded middle in maths might help quantum theory and relativity find common ground.
There is some argument about whether the sterile neutrino is the source of the unidentified x-ray line and thus a candidate for dark matter.
A plain English description of how light can be both a wave and a bunch of particles, as proven by the double-slit experiment.
I simply had to have an app that allows me to create new universes and base all my decisions on quantum mechanics.
A very simplified layman's view of the Schrödinger's cat paradox, where a cat can be both alive and dead at the same time.
People often confuse speed and velocity and thus end up confused about what acceleration is. This is a short explainer of those terms.
An article by Sean Carroll on Quanta Magazine looks at what quantum probability might mean. I provide an intro and then link to the article.
A Quanta Magazine article about a new measurement of the size of the proton. Previously they thought protons might shrink in the presence of a muon, but it turned out their original measurements of the standard proton were wrong.
More than 100 years after Einstein proposed it, his General Theory of Relativity is still being tested. In this case, Einstein's 'Equivalence Principle' is put to the test.

An overview of the 1927 Solvay Conference, which could be the greatest meeting of minds the world has ever seen.
A Quanta Magazine article about ideas that have sprung up as a result of the Shuttlecock Universe idea Hawking proposed in the 1980s.
The University of Cambridge has proposed a new form of currency that could be the future of stellar financial transactions.
An article on ArsTechnica looks at a new way to see whether the fundamental physical constants were different in the past.
'Eugene's Friend', a thought experiment that suggests measurements are relative, has be proven to be true.
