True enough, but who knows what kind of technology we'll have in the future. Of course it's all just speculation

^ Heard of it but not too familiar with it.
they had it in mass effect (well fiction is where it all starts anyways), the basic idea is that you keep two particles in a state of quantum entanglement (forgot the exact science theory and how they do it), and no matter how far you separate them, they are always at the "same place" as in they are not affected by distance and all the other nasty hurdles that get in the way

is if I have one here and you got the other one in a galaxy 100000 trillion light years away we can still send info as quantum bits as though we are in the same room, this is done by spinning or doing stuff to the particle and then translating the stuff into other stuff XD sorry I'm not that good with scientific lengo
