What would it really take to travel at or beyond the speed of light? In this video, we break down the hard physics Hollywood skips: why nothing with mass can reach light speed, how energy needs ...

The idea was first hypothesized about 70 years ago. In a bizarre repercussion of Albert Einstein's Special Theory of Relativity, objects traveling close to the speed of light appear flipped over. The ...

What's more, when you're traveling at or close to the speed of light, the distance between where you are and where you're going gets shorter. That is, space itself becomes more compact in the ...

Time would pass differently on Earth for travelers moving at light speed, with thousands of years potentially elapsing while ...

If there is an absolute law in the universe, it’s that nothing can travel faster than the speed of light. For science-fiction enthusiasts, that’s a bit depressing. Space is big, and while the speed of ...

Next time you’re trying to squeeze into your skinny jeans, it might pay to give physics a thought—because depending on how fast you’re travelling, you fat frame could look a little different. Randall ...

Pointed at a laser pointer, the camera's able to capture a beam of light at two billion frames per second, showing it ...

The most distant galaxies in this deep field image from the James Webb Space Telescope appear as small, faint dots—and are receding from us faster than the speed of light due to cosmic expansion. If ...
