So satisfying. Do you think it's possible to take the end state of this simulation, reverse the velocities, and watch the 50 pendulums (pendula?) come together again, or do chaotic dynamics + floating point rounding errors make that impossible?

sure.. or i can just reverse the gif lol

Not as satisfying ;-)

but to answer your question newtons equations of motion are invariant under time reversal, so yes it's totally possible

Sure, but what I'm wondering: say the original sim goes from t=0 to t=10. Then reverse velocities, with the new sim's time going from t'=10 to t'=0. Due to floating point rounding errors, the state at say, t'=5 is going to be very slightly different from the state at t=5...
