How do we know the speed of light – and why does it have a speed limit at all? Leah Crane explores the history of one of the ...

Researchers at Aalto University have demonstrated single-shot tensor computing at the speed of light –– a remarkable step ...

Silicon photonics converts electrical signals into optical signals and back again, allowing data to be transmitted as pulses of light. A laser generates a near-infrared light which is then modulated ...

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 ...

Imagine this: a tiny needle hurtling toward Earth at the speed of light. At first glance, it might sound like no big deal. After all, it’s just a needle. But in reality, a projectile moving this fast ...

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 ...
