The Light Cone (fictional concept)

The Light Cone is a conceptual tool from physics that represents all possible locations in space and time that could be affected by or could affect an event, considering the speed of light as a universal limit. Imagine shining a flashlight at a point in space: the cone-shaped area illuminated over time forms the light cone. Inside it are all events that can influence or be influenced by that event, respecting the speed-of-light constraint. By visualizing this cone, scientists understand causality and the structure of spacetime, helping explain how information and influence propagate through the universe.
