In water, light travels at 75 % the speed it would in the vacuum of outer space, but the electrons created by the reaction inside of the core travel through the water faster than the light does.

Explore the science of light speed, if faster-than-light travel is possible, and the mysteries of moving slower than light. Skip to main content. Open menu Close menu. Space. Search.

N othing can travel faster than the speed of light. The problem with trying to surpass it is that as you go faster, the more kinetic energy you have. But relativity tells us that energy is the same as ...

Indeed, to our knowledge so far, nothing on or off our planet can travel faster than the speed of light. This has been proven time and time again through the laws of special relativity , put on ...

Nothing can travel faster than light — in a vacuum. But when light slows down, sometimes matter can blaze past that speed limit, creating a stunning glow called Cherenkov radiation.

The speed of light in a vacuum is the absolute speed limit of the universe. Nothing will go faster than 300,000 kilometers per second (186,000 miles per second), according to Einstein's work, as ...

In short, if faster-than-light travel can occur then observers in different reference frames begin to disagree about the order of events. For a simplified example, imagine a ...

Warp drives theoretically get around the speed of light problem by wrapping an object (like a spaceship) in a bubble of spacetime. The ship remains stationary, but the bubble itself can travel at ...

Nothing can travel faster than light, or 299,792,458 meters per second. But a certain group of particles acts as if it can, a team of physicists recently concluded, potentially paving the way for ...
