About this Simulation

This simulation visualizes how events that appear simultaneous in one reference frame are not simultaneous in another, a core concept in special relativity. Learners manipulate spacetime diagrams to observe how simultaneity depends on the observer's frame of reference and explore the relativity of simultaneity through interactive exploration.

Learning objectives: Understand that simultaneity is relative and depends on the observer's reference frame | Visualize the Lorentz transformation and its effects on spacetime coordinates | Apply spacetime diagrams to analyze events in different inertial frames
