No Object Can Travel Faster Than Light, So Why Doesn't That Apply To Warp Drives? We cannot break the speed of light, but hypothetical warp drives are a neat trick for getting around that.

Imagine–a trip around the world at the speed of light. With those enormous distances in mind, consider Cristina’s question: How can light travel across the universe and not slowly lose energy?

What would happen if we could travel at the speed of light? In this mind-bending video, we explore the theoretical concept of light-speed travel and what it would be like if humans could somehow ...

The colloquial term “warp drive” comes from science fiction, most famously Star Trek. The faster-​than-light warp drive of ...

Curious Kids is a series for children of all ages. If you have a question you’d like an expert to answer, send it to ...

If travel to distant stars within an individual’s lifetime is going to be possible, a means of faster-than-light propulsion will have to be found. To date, even recent research about ...

Do photons wear out? An astrophysicist explains light's ability to travel vast cosmic distances without losing energy by Jarred Roberts, The Conversation ...

In short, if you accept that there's no way to travel faster than light, the best alternative is to increase the speed of light, a feat scientists first achieved in 2208.

We take a look at what would happen to the human body if it could travel at the speed of light.

For a spacecraft like that to reach a black hole in such a relatively short time, there would have to be a black hole 20-25 ...

When we measure the speed of light, it's always in two directions. Measuring it in one direction may be impossible.
