Why can't we move faster than the speed of light? Well, the reader's question was a tad more complicated than this, but it all boils down to the same thing. He wanted to know what would happen to ...

So, how can galaxies be traveling faster than the speed of light when nothing can travel faster than light? I'm a little world of contradictions. "Not even light itself can escape a black hole ...

Scientists have apparently broken the universe's speed limit. For generations, physicists believed there is nothing faster than light moving through a vacuum -- a speed of 186,000 miles per second.

Kevin Forward wants to know, as he asks: In the first millionths of a second of the Big Bang did the universe not expand faster than the speed of light? As a spoiler: no, it didn't expand faster ...

"It is impossible to travel faster than light, and certainly not desirable, as one's hat keeps blowing off." Woody Allen, Side Effects Last summer, a small neutrino experiment in Europe called ...

Since Einstein, physicists have found that certain entities can reach superluminal (that means "faster-than-light") speeds and still follow the cosmic rules laid down by special relativity.

In those observations, the stream was flying past at only four times the speed of light. That still didn’t seem right. Nothing in the universe can go faster than the speed of light. As it ...

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 ...

For example, the crack of a whip is caused by the tip creating a sonic boom as it travels faster than the sound speed. What Is Faster the Speed of Light? Nothing can travel faster than the speed of ...

So, what about that part with Flash? This is not a spoiler, since Flash does this in other situations: He needs to run faster than the speed of light in order to go back in time to warn the ...

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 ...
