PHYS102: Introduction to Electromagnetism

It turns out that the speed of light can only be constant for all observers if we also admit that c plays a special role in the mechanics of material objects. This means that c was discovered to be a universal speed limit not just for light but for all objects that show any kind of motion relative to some observer!

Watch this video, which provides an overview over the often counter-intuitive conclusions that must be drawn from this fact.
