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
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
Light usually travels in straight paths, but what if it was twisted, spun, and behaved like a mini-tornado? Scientists have now made this possible by creating optical vortices—small swirling particles of light in a microscopic system. Until now, generating such complex light systems required multiple setups or complex nanostructures, making it difficult to scale. A … Read more
Researchers have developed a new holographic data storage system that records and retrieves information in three dimensions by combining three important aspects of light – amplitude, phase and polarization. By using these three together, this method allows more data to be stored in one place, providing a potential solution to the world’s growing demand for … Read more
Long ago, billions of years ago, the Universe was covered in darkness. It wasn’t until the first stars began to shine that space became transparent and light flowed. Surprisingly, none of those early stars, known as Population III, have ever been found. Now, astronomers have found the next best thing: A star so chemically depleted … 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
