i was thinking today, what if we could make a fibre optic type tube, and then a small little vessel which could carry human beings at the speed of light from one side of the world to another side of the world, like fibre optics carry light signal from one side to another side making our chats, and Skype calls so instant and of almost no cost, this way we can have transportation from far away at no cost also.
