If humanity wants to travel between stars, people are going to need to travel faster than light. New research suggests that it might be possible to build warp drives and beat the galactic speed limit.
If you are a sci-fi junkie you've probably wondered what would happen if you were unlucky enough to fall into a black hole. How well you'd fare all depends on the type of black hole.
When you see a bolt of lightning, do you immediately start counting to see how far off a storm is? An atmospheric scientist parses the practice.
The speed of light is of great advantage when sending data over the internet, but it is a real challenge to master on a small chip. A new design offers a solution: convert the energy to sound.
Many people think relativity puts a hard speed limit on the universe, but it actually opens up the possibility of faster-than-light travel - if we can overcome some significant practical hurdles.
There's a cosmic speed limit that unfortunately means you aren't going to be firing up warp drive anytime soon.
