The speed of light is one of the most famous constants in physics, yet it has never been directly measured in the way most ...

Ok, it's been almost a decade since I've had to study Maxwell's equations, but I remember a certain facet from those equations that always astounded me. It was the fact that the speed of light could ...

The universe has a speed limit, and it's the speed of light. Nothing can travel faster than light — not even our best spacecraft — according to the laws of physics. So, what is the speed of light?

The universe comes with a built‑in speed cap, a hard limit that shapes everything from how stars shine to how cause and effect unfold. That limit is usually described as the speed of light, yet the ...

Every high school physics student knows c, or the speed of light, it’s 3 x 10^8 metres per second. More advanced or more curious students will know that this is an approximation, and the figure of 299 ...
