If there is an absolute law in the universe, it’s that nothing can travel faster than the speed of light. Space is big, and ...

Recently, the James Webb Space Telescope observed signals that moved faster than the speed of light. Does this mean that faster-than-light travel is real? If not, what explai ...

From early experiments with lanterns to Einstein’s revelations about space and time, the speed of light has proven to be far more than a number: it’s the cosmic constant that defines reality.

For the first time, physicists have simulated what objects moving near the speed of light would look like — an optical ...

Every year, our planet makes one full trip around the Sun. And while that means we’re already moving at breakneck speeds, we’re about to ramp that speed up. Like, way up! Let’s turn Earth into a ...

The Universe is immense. Our most powerful telescopes observe galaxies whose light has taken more than 10 billion years to ...

Some things we see in space appear to outpace light. Now we are learning to harness these bizarre optical illusions to ...

You know that scene in the film Contact where the “Machine” is spooling up, its three spinning rings kicking out crazy light and an electromagnetic field powerful enough to pitch nearby Navy ...

Scientists at CERN, the famous Geneva-based physics lab, have just called into question one of the most hallowed equations in physics: E = MC2. Scientists, the AP explains, have clocked subatomic ...
