👯 Twin Paradox (2D)

2D Canvas simulation of the Twin Paradox. Launch a rocket twin at relativistic speed on an outbound-turnaround-return trip and watch the age gap grow against a stay-at-home twin via real Lorentz time dilation.

⚙ Under the hood

Launch a rocket twin on an outbound-turnaround-return trip at relativistic speed and compare their elapsed proper time against a stay-at-home Earth twin. Adjust travel speed (beta = v/c) and trip distance to see the real gamma-factor age gap play out on paired analog clocks and a spacetime diagram.
