[ WP ] Backwards time travel is a reality , however forward time travel is not . Therefore when you go back you must relive everything again .

Life had been rough. It had been nearly a decade since the faculty at my would be alma mater laughed me out the door when I had proposed that the classical model of physics was in fact absurdly wrong and did not explain the results I had witnessed in the lab. Relegated to insubstantial work reviewing algorithms at a local software company, I had spent nearly all my free time reviewing my old thesis, refining, perfecting something that even I did n't know how dangerous it could become. 
 
 The first signs of Spring had started to appear, rain turned to snow, trees waking from their slumber, and I had finally begun to actually understand the nature of my little side project. The connection of our perception of reality to its actual nature. Time was fluidic, could be warped and manipulated, but the energy requirements were immense. Any device to manipulate time could only be powered by the consumption of the universe itself which, terrifyingly, is not as hard to do as would seem. After a prolonged and bitter fight between my inquisitive nature and my morality, I vowed to make this device. Anyway, what ’ s the harm as long as I prevent myself from creating it again? 
 
 A time machine powered by the destruction of the universe is not a big as you would think, small enough, in fact, to fit inside a box the size of a microwave. I can ’ t fathom how many hours I spent checking, rechecking, and checking again that everything was correctly placed. After all, if the time machine portion did not work all that would be left of the universe would be nothingness. Quite a dreary thought indeed. So with the flip of a switch and a long string of words far too vulgar to repeat, I destroyed the universe.
