Researchers from the Department of Physics at the University of Warsaw, working with teams from the Łódź University of Technology, the Warsaw University of Technology, and the Polish Academy of Sciences, have created a structure that can capture infrared light with a layer of only 40 nanometers. Their method is based on a design known … Read more
A game with only three moves may sound simple. In quantum physics, it can still break old logic. That is the focus of a new experiment led by physicist Zhenghao Liu and his colleagues at the Technical University of Denmark. Writing in Science Advances, the team has constructed what they describe as the Greenberger-Horne-Zeilinger triple … Read more
For the first time, physicists have discovered that ‘holes’ of light can travel faster than light itself. They are known as phase singularities or optical vortices, and since the 1970s, scientists have predicted that, just as the eddies in the river can move faster than the water flowing around them, so can the waves of … Read more

A photon from a star billions of light-years away takes no time to reach a telescope. It’s not too little time. There is nothing. That result is not a measured or poetic way of speaking. It comes directly from the mathematics of special relativity, and it points to another strange thing about the nature of … Read more
Elliot McGucken These photos of 70-foot-tall cones of light shining in the California desert may look pretty, but they have a surface and actually represent some interesting ideas about the evolution of space-time. Dr. Elliot McGucken is a nationally recognized photographer and Ph.D. a physicist. He likes to combine his two passions, which he believes … Read more
Your hands can be a useful tool for measuring the night sky. (Image credit: Created with Canva Pro) Of the five bright planets with the naked eye, the two that are best for viewing in April are in the evening sky. Amazing Venuslow west-northwest about two hours after sunset, and bright Jupiterwhich flies high in … Read more
Scientists may have invented a night vision laser. Our incredible progress as a society has been increasing exponentially in recent years. When a team of scientists did it The chip is too thin to study invisible light of the world, they have mistakenly created something else entirely, the evergreen tree. How can this new invention … Read more
Scientific experiments can change the world around us. Throughout history, several experiments have led to amazing inventions that have rewritten our collective rule book. But the experiment of making light materials can produce a new flexible film that produces its light and energy? How did this new energy and lighting technology come about? How ultra-thin … Read more
Dark spots in light waves may appear to disrupt the speed of light, according to new research from scientists at the Technion-Israel Institute of Technology, confirming the predictions of a half-century-old theory. What the team calls “dark points” are actually vortices – tiny holes in the wave structure of light – as revealed in a … Read more
