Previous models explored the illusion, but this is the first time it has been actually recreated in a lab setting.

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

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 ...

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 ...

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 ...

Philosophical-sounding edge cases help scientists refine their models and explore how and where their theories may fail.

My telescope, set up for astrophotography in my light-polluted San Diego backyard, was pointed at a galaxy unfathomably far from Earth. My wife, Cristina, walked up just as the first space photo ...

James is a published author with multiple pop-history and science books to his name. He specializes in history, space, strange science, and anything out of the ordinary.View full profile James is a ...

It may be possible for a swarm of ultralight nanocrafts—propelled by a laser and traveling at a third of the speed of light—to make it to a black hole within about a century. For a spacecraft like ...

Cosmic speed limits can be a major inconvenience but they've rarely stopped science fiction in its tracks. When it comes to space travel, Albert Einstein's theory of relativity is a major ...
