Science fiction authors and readers dream of travelling at the speed of light, but Einstein tells us we can’t. You might think that’s an arbitrary rule, but [FloatHeadPhysics] shows a different way to ...

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 ...

Here is a thought experiment for you: imagine shining a powerful laser at the moon, the beam cutting through space until it lands on its dusty grey surface. Now flick the laser so the spot of light ...

Scientists observed a supermassive black hole in galaxy NGC 3783 releasing wind at 20% of the speed of light after a sudden X-ray flare. New data from XRISM and XMM-Newton explains how magnetic activi ...

Astronomers observed the supermassive black hole in galaxy NGC 3783 ejecting ultra-fast winds after a powerful X-ray flare.

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 ...

While humans and classical computers must perform tensor operations step by step, light can do them all at once.
