Light Cones and World Lines

The video tutorial provides a comprehensive overview of relativistic physics, focusing on how massive and massless particles move in relation to light cones in space-time. It explains the concept of space-time pictures and the representation of light cones, emphasizing their role in understanding light behavior. The tutorial introduces Minkowski space, a four-dimensional geometry used in Einstein's special theory of relativity, and discusses the constraints on particle speed, highlighting the concept of world lines. The tutorial concludes by differentiating the movement of photons and massive particles within these cones.

Describe what would happen if a particle were to travel outside of the light cones.

What is the difference between the behavior of massive particles and photons in relation to the cones?
