When Galileo's name comes up, most people think about his contributions to observational astronomy. However, he did lots of other stuff including investigating the speed of light. During his time, ...

Researchers in Europe have developed a technique for obtaining accurate laser-based measurements of objects hidden behind complex scattering structures. They say that their mathematical formula, which ...

WEST LAFAYETTE, Ind. -- Purdue University researchers have demonstrated a new method for using lasers and semiconductors to more accurately measure the velocity of a moving object. The method relies ...

This is a subject close to my own heart - I was slightly involved in an earlier iteration of very similar research. The aim is to find out how rich or poor people are in remote or otherwise ...

The speed of light is a fundamental constant, approximately 299,792,458 meters per second. It's the same for all observers and hasn't changed measurably over billions of years. Nothing can travel ...

Pasadena, CA — Ohio State University researchers have found a way to measure distances to objects three times farther away in outer space than previously possible, by extending a common measurement ...

Can your microwave oven really measure the speed of light? Yes, it can be done. And since many of the suggested experiments also involve chocolate, it will be done. Oh yes, it will be done. First, a ...

Scientists unveil the first global index correlating night light with threats to coral reefs. The Lights Proximity Index offers a new tool for conservation and for studying the direct and indirect ...
