At first sight, this is remarkably more accurate that the "slower speed of light" game from MIT that was made available all those years ago (~2012).
Many issues with the MIT game were discussed here:
https://physics.stackexchange.com/questions/43695/how-realistic-is-the-game-a-slower-speed-of-light/587149#587149 https://physics.stackexchange.com/questions/43695/how-realis...
While the thread lists multiple issues, the issue that I found was with modeling temporal aspects of relativistic doppler (I also reported it on the github repo of the "slower speed of light" project, but that doesn't appear to be maintained):
https://github.com/MITGameLab/OpenRelativity/issues/17 https://github.com/MITGameLab/OpenRelativity/issues/17
In this game, it looks like the temporal component of the Doppler effect is modelled correctly.
- dmitrybrant 23d agoThanks! Yes, I'm trying to pay extra close attention to modelling every perceivable effect as closely as possible. The remarkable thing is that none of the mathematics is particularly complicated, so if you get the math right, then all of the predicted effects emerge automatically.
- dotancohen 22d agoThis is probably one of the most important comments on HN, seriously. A concise summary that once we get the model right, the emergent behaviour matches observations. Very reminiscent of the Casimir effect experiments.
- post-it 21d agoHow come the things I'm travelling towards seem to stretch further away the faster I go? Doesn't length contraction work the opposite way? Edit: ah I did some googling and relativistic aberration has the opposite effect and beats out length contraction.
