Some distant day, when the government prioritizes science enough to convert it into bureaucracy as it has with everything it hasn't already destroyed, the dreams of hundreds of sci-fi/online fetish fiction writers will be realized as inter dimensional travel becomes possible, for (as the link you clicked on described in neat enough terms, I hope) Fun and Profit.
You know the drill...we live in a universe of a thousand million katillion other universes, connected like an enormous web, or else floating together in the ether like a so many bubbles.
There's a lot of universes, you understand. One for every possible eventuality, no matter how big or small.
At a certain point, various enterprising scientists, backed with the money of mega corporations, were able to device a way for individuals to be transported from our universe to countless others to...well, see the sights, as it were.
The initial purpose for this work was so that we could probe the possibilities of other timelines and see how we might improve the quality of life in OUR world. But money still needs to be made if the enterprise is to exist at all.
So now, about three years into this new endeavor: the Horizons Project has opened to the public. Anybody can dimension-hop. Well, not ANYBODY. On principle, you should at least do some necessary reading, right? Take some fitness courses, maybe read a survival guide or two?
Not that any of the numerous waivers you'll have to sign will RECOMMEND any of that.
So.,..what'll it be?
Tourism, science, some nebulous third option that will no doubt be added eventually?
