When it comes to space, we have a problem with our human desire to go everywhere and see everything. A huge problem. It’s space. It’s far too vast. Even at the maximum speed permitted by the Universe, it would take … Read More
Most of us grow up knowing that the speed of light, which tops out at 300,000 kilometers (186,000 miles) per second, is the prevailing law that limits how quickly information can travel through empty space. While photons are unlikely to … Read More
Here’s a question… how long does it take sunlight to reach Earth? This may appear to be an odd question, but consider it. The sun travels at the speed of light. Photons emitted from the Sun’s surface must traverse the … Read More
We’ve wanted to visit other star systems for decades. There’s just one problem: they’re so far away that even the closest one would take tens of thousands of years to reach using conventional spaceflight. Physicists, on the other hand, are … Read More
For the first time, scientists have managed to capture the dual natures of light – particle and wave – in a single electron microscope image. Until now, scientists could only capture an image of light as a particle or a … Read More
LIGHT IS FAST. In fact, it is the fastest thing that exists, and it is a universal law that nothing can move faster than light. Light travels at 186,000 miles per second (300,000 kilometers per second), and it takes just … Read More
