Fortunately, time-travel does not exist. With it, the human race would try to solve past mistakes in isolation, erase any knowledge gleaned from making them, and create a chain reaction of unforeseen consequences. These could destroy the past, along with the present and future simultaneously. Time itself could become the ultimate weapon of mass destruction.
The realization that time can behave like another direction of space means one can get rid of the problem of time having a beginning, in a similar way in which we got rid of the edge of the world. Suppose the beginning of the universe was like the South Pole of the earth, with degrees of latitude playing the role of time. As one moves north, the circles of constant latitude, representing the size of the universe, would expand. The universe would start as a point at the South Pole, but the South Pole is much like any other point. To ask what happened before the beginning of the universe would become a meaningless question, because there is nothing south of the South Pole.
The vibrant matte amethyst dial made the gleaming hour and minute markers seem to come alive. The long, thick hands were fragile, yet ceaselessly ticking by, like life itself. Countless hours must have been invested in the bezel, meticulously hashed all the way around. The tachymeter claimed prominence as if asserting that distance travelled over time should be of paramount importance. Never had the sheer pace and inevitability of time been better captured in an object.
And that was the thing, wasn’t it? When life rode on its highs, you wanted it to go on forever. But in the depths of the invariable dives, you’d be happy to be put out of your misery, because whatever awaited beyond this life had to be better than this shit on Earth.
