first, i dont post alot, i just like to read. i havent gone to college so please dont bash to hard
i do think this is an excellent idea. i always imagined a giant sphere filled with tubes. each tube is a verion of what could be. since matter is neither created or destroyed there can only be a finite number of tubes and versions. each choice you make, the opposite is being made in another tube.
to add to this, what if the walls of each tube was actually C . if by jumping to C+.0000001 would this allow you to start crossing through different tubes?
i understand you cant accel to C but maybe a quick instant jump. slowing down would be a problem also but this is all in my little mind.
