🌀 Wormhole Time Machine: 2D Spacetime Diagram

Interactive 2D spacetime diagram of a Frolov-Novikov wormhole time machine: drag the turnaround point of the travelling mouth to set its speed and trip length, watch the clock offset grow as Delta = T(1 - sqrt(1 - v^2)), and fire light pulses from the home mouth to see when they re-emerge before they left (a closed timelike curve).
