In physics, they are all the same thing. But to you, me, and everyone else, time moves in one direction: from expectation, through experience, and into memory.… Read more “Time Might Only Exist in Your Head”

“Optical quantum computing is still a long way off, but our successful experiment to stop light gets us further along the road,” said lead researcher. Physicists have… Read more “Physicists successfully stop light”

  A theoretical species of particle might answer nearly every question about our cosmos—if scientists can find it. The universe is unbalanced. Gravity is tremendously weak. But… Read more “The secret lives of long-lived particles”

The cognitive scientist Donald Hoffman uses evolutionary game theory to show that our perceptions of an independent reality must be illusions. As we go about our daily… Read more “The Evolutionary Argument Against Reality”

All light sources work by absorbing energy – for example, from an electric current – and emit energy as light. But the energy can also be lost… Read more “Superfast light source from artificial atom”

A CENTRAL IDEA OF PHYSICS is that reference frames don’t change fundamental laws. It shouldn’t matter where you observe an event or how fast you are moving, the laws of… Read more “Calculate Your Way to Special Relativity”

Dark matter could be made of particles that each weigh almost as much as a human cell and are nearly dense enough to become miniature black holes,… Read more “Dark Matter Particle Could be Size of Human Cell”

Light behaves both as a particle and as a wave. Since the days of Einstein, scientists have been trying to directly observe both of these aspects of… Read more “The first ever photo of light as a particle and wave”

New research supports an old, more intuitive theory of how sub-atomic particles behave. Cathal O’Connell explains. With its ideas of particles zipping in and out of existence,… Read more “Quantum surrealism”
