Casimir cavities are mysterious spaces between microscopic metal plates in a vacuum. Areas of diminished energy between the ...

Everyone loves “break the record” stories—until physics shows up with a hard rule. The speed of light isn’t just fast, it’s ...

The method involves stitching together many thin “slices” of light reflecting off an object.

Scientists captured the first images of the Terrell-Penrose effect, showing objects near light speed appear rotated rather than compressed in photos.

If light traveled very slowly, strange things would happen. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. Breaking space news, the latest ...

The Parker Solar Probe, currently the fastest human-made object, travels at 0.05% the speed of light (approximately 330,000 mph). Reaching 1% the speed of light requires an immense amount of energy ...

Neutrino detectors, like the one used in the BOREXINO collaboration here, generally have an enormous tank that serves as the target for the experiment, where a neutrino interaction will produce ...

The hyperdrive from Star Wars appears to depict an ultra-relativistic motion through space, extremely close to the speed of light. Under the laws of relativity, you neither reach nor exceed the speed ...

During a meeting with the Mars Exploration Program Analysis Group, an internal NASA working crew dedicated to supporting missions to Mars included a pitch from Elon Musk's SpaceX to deploy Starlink ...

The glow from faster-than-light particles gives us a unique way to explore the universe. Nothing can travel faster than light — in a vacuum. But when light slows down, sometimes matter can blaze past ...

It is hard to remember that a lot of high tech research went on well before the arrival of electronic computers, lasers, and all the other things that used to be amazing but are now commonplace.
