i guess they haven't designed a time machine in the future. i have an unspoken agreement with myself that when they do, the first thing i do with mine is race back to this time period and fist fight myself. i have not been punched in the face by my self from the future, so i think it's safe to assume that we never invent time machines. that, or they don't give them to just anyone. maybe we invented them but never got proof that they worked. like if you sped ahead in time to the end of the world, the earth might be covered in magma. thus destroying the machine upon landing and convincing the scientists back in the present (which is the future) that the experiment didn't work. all while their colleagues in the future scratch their fingers helplessly against the glass in the slowly melting vessel as they descend into imminent death in a lake of magma. the world must be in some sort of unlivable...or even unlandable state. otherwise the world could never end for people. someone could time machine ahead, see how it ends, return back, get a girl, race back ahead again to just after the end of man, coitus her, procreate, and continue the cycle of life endlessly. unless of course there is nowhere to live - as there probably isn't. which is a shame because i think i could kick the hell out of myself in the future. unless i started taking karate lessons and steroids at some point...then i'm in trouble. (note to self - start taking karate lessons and steroids to pummel current self in future)
