This demonstration illustrates causal relationships. Check off any tick box (or any combination of the tick boxes) to see the regions in spacetime that, relative to the origin, are causally connected, causally disconnected, or on the origin’s light cone. Then, use the sliders to see the same causal relationships relative to any other chosen spacetime location.
