One story idea that has always been a favorite of mine is parallel universes. Stories where the heroes travel to worlds are mirrors of eachother. I love to read stories where the worlds may resemble something close to what we know with minor differences, and stories where the alternate world has been wrecked because of some catastrophic event where Johnny McBoogernose was elected mayor in Hicksville, USA instead of Timmy Straightentrue.
When I was a freshmen in highschool, I discovered Stephen King's series The Dark Tower, and they remain some of my favorite books. I love how they explore alternate worlds and alternate time lines and the idea that the universe is like an onion in reverse -- there are layers of worlds stacked on layers of worlds and each one may only differ slighly, while some may be enormously different.
Well, oh denizens of the SoaM universe, I have invented a machine that will let you explore alternate dimensions. The diagram of my invention can be seen below, although it may be too technical for most of you unscientifical folk. Just trust me that I spent many hours perfecting this design.You may question the morality of this. "Jason," you may protest, "couldn't even glancing briefly at another world throw ours into chaos, much like messing with the time stream." "What is this, freakin' twenty questions?" I would reply with anger. Seriously, why in the world would you be questioning me anyway, I just invented a freakin' transdimensional portal generator. When my findings are reported to the International Scientists Organization and Recreational Center -- or I-Soars -- I'll be able to buy and sell you guys like goldfish anyway....
...anyway, until the boys in white coats recognize my excellence, I will offer free rides to anyone who wants to visit a few alternate dimensions. Remember, these things may frighten you, but just remember that this is only a demonstration and a real ride will cost you your first born child -- so, basically, cheaper than a full tank of gas.
Without further ado, SoaM of the Other Worlds: SoaM Beta, SoaM Gamma, SoaM Delta, SoaM Epsilon -- (this world calls their site "The" Scribblings of a Madman. Everyone knows that my scribblings are "THE" scribblings, all others are imitators. I'm SoaM Alpha.)
I hope you all enjoyed your trip. Please watch your step and thank you for travelling.
