Now I think about it, I should have called it parallel worlds... What can you do?
It's not an easy thing to think of. We imagine the world with a difference in the past as this world except one thing has changed. But everyone knows of the butterfly effect, and how a flap of wings creates a hurricane in a distant land. Why am I the only person I know that connects the two?
Some people connect the two quite well, considering multiverse theory. Heck, I'm writing this with the family guy episode where Stewie and Brian travel across dimensions lodged firmly into my thoughts. But if you consider all the tiny changes that made somebody's day better, and consider what would be different if you did something a tiny bit different that one time.
Example, if I had hygiene. I'm more sociable, I become more arrogant, my friends in this reality dislike me, I'm a posterior-hat and live an unfulfilling life.
Just think of what one change would make. A personal thing that I find, whilst making good viewing material, a logical issue in my 3rd favourite film, Back to the Future, is Marty's conception. While he manages to hook his parents up, you just know they'd be even more in love then the previous time. Therefore, they'd want kids faster, and they'd concieve the kids at a different point in time. Beyond just changing birthdays, you can't ensure that the batch of genes that made the kids would be the same, and so the kids would be pretty different. Heck, the first kid could become so irritating, they don't want more than one, so Marty's not concieved anyway.
Sorry if I'm rambling, but seeing someone fade on a tv show makes me think 'no, if you traveled back in time, the moment anybody sees you, you just stop'.
Still, with enough theories out there, you can have any reality you want. I believe that if the universe intended me to have certain things happen to me, they'd happen in SOME way. With the hygeine thing, I think I'd still have made the vital connections that led me here, take similar choices, and be in the same situation but a lot more respected.
I'm actually quite interested in what reality would be if I was female, or a contortionist, or far less flambouyant... I'm most looking forward to the universe where frictionless motion was further researched, and they found a lasting but light source of power for it. WHERE'S MY BLEEDING HOVERBOARD?! There's probably a universe where I inspired my friend to make a blog after mine, or where I mentioned firsts in blogging, or pointed out the obvious, or used a clever font.
Eh, I'm good with this one. And the nicer hygeine one, that's good too...
