The idea of traveling faster than the speed of light (FTL) has been a popular idea long before [Alcubierre] came up with the first plausible theoretical underpinnings for such a technology.

While these do not disprove Einstein's theory, they give us insight into the peculiar behavior of light and the quantum realm. When objects travel faster than the speed of sound, they generate a ...

When Albert Einstein said that nothing travels faster than the speed of light, he didn't talk about objects that could already be traveling faster than light. This is a mind-boggling idea that ...

What if we could travel faster than light? This episode explores why light speed is considered an unbreakable limit, the challenges of FTL travel, and what it could mean for space exploration.

(via Sabine Hossenfelder) While time travel is cool science fiction tech, it seems to directly contradict our current understanding of physics. But what about, instead of moving a whole person back in ...

Which is pretty fast! Not even Superman managed that. In fact, nothing can travel faster than the speed of light. By comparison, sound travels just 340 m in one second, about the length of three ...

You can never travel faster than the speed of light. At least, that's what we understand through Einstein's special theory of relativity, the revolutionary theory that united space and time can ...
