alt Hacker NewsThis is awesome, thanks!
I wonder if you could make it multiplayer and then get the effects of time dilation?
In my imagined world I also wanted to explore speeds above the speed of light. You could just stick to galilean transformation, take a very low speed of light and go from there. The world you get should be pretty bizarre.
I suppose the problem in multiplayer is that everyone has the same wall clock time, so you couldn't easily have consistent time dilation and related effects such as the twin paradox.
