Does this take into consideration that your mass increases as you travel closer to the speed of light?

No, I'm not sure what that would suggest - how would that need to be accounted for? Maybe some fraction of light speed would need to be the upper bound, low enough that mass increase wouldn't have a material impact? I'm having trouble understanding what impact the mass increase would have in the first place.

It's a cool project! Just as others say, once you get to a notable fraction of the speed of light, you need to account for relativity.
