go ahead, get your life, the universe and everything out of the way, we all know it's 42.
now down to business:
what if the universe actually runs on Improbability rather than probability?
think for a moment. each movement you make has a certain chance to happen. each quark has a chance to move a certain way. each atom has a chance to randomly disassemble. everything has a chance, a percent chance, for any action imaginable to happen, and there are no zero percent answers.
in a world of improbability, the opposite would be true. the low chance answers would happen first, and "normalcy" would be rare.
at one moment the universe could blink into nothing, turn itself inside out, turn back on, explode and implode simultaneously, form into the shape of a giraffe, atoms become cube shaped, time inverts where it's distance * Speed instead of Distance/Speed, leading to maddening results, or even, as improbable as it seems: mankind's existence in a world where everything is constantly experiencing the least likely things to happen in paced out succession.
everything happens because it has a probability to happen. the world revolves around this idea. there's always a .1 * 10^-432nd chance you spontaneously combust from energy overconsumption.
in a world of improbability, unreasonability trumps reason. the wildest scenarios are beyond human perception and confounding. after all, if you look at what The Heart of Gold does, it simply narrows down the probability of being in a specific place at a specific time working backwards.
through messing with improbability, we gain the ability to teleport across space and time. it doesn't matter when, where, or how we go. thank God the Heart of Gold has an end radius. because if it affected the entire universe, all life would be doomed to a world of improbability. and I'd probably be a butt ugly Vogon with a pension for a lugnut plantation and a mortgage on some random dude's soul. because while Im lucky, when Im not lucky, I'm REALLY unlucky.
