Apparently, NASA has found evidence of a parallel universe where time works differently. No time doesn't go backwards, going forwards apparently yields the same type of result as going back in time would in our universe. Perhaps it's a universe undergoing The Big Crunch, gradually returning to start. What'd be even more interesting is if travel there has ever-reducing distances between planets and galaxies, and if going to a point and returning to this universe would mean you would end up at that point in THIS universe, maybe many, many times FASTER than the speed of light! As for time spent in the universe, it could be that you'd have to avoid being there too long to avoid de-aging too much, but crossing the universe would be a breeze with the above factors! Back and forth between about 20 and 70 years of age, effectively forever :O And what about the physics of the parallel universe or even OTHER parallel universes? Indeed, the Square Cube law that kills our joy in this universe
