This Book Is Full of Spiders: Seriously, Dude, Don’t Touch It (John Dies at the End, #2)

by David Wong

Your body is just made of a few different types of atoms. Carbon, hydrogen, oxygen, and so on. So this transporter machine, there is no reason in the world to break down all of those atoms and then send those specific atoms thousands of miles away. One oxygen atom is the same as another, so what it does is send the blueprint for your body across the beam. Then it reassembles you at the destination, out of whatever atoms it has nearby. So if there is carbon and hydrogen at the planet you’re beaming down to, it’ll just put you together out of what it has on hand, because you get the exact same result.” “Sure. “So it’s more like sending a fax than mailing a letter. Only the transporter is a fax machine that shreds the original. Your original body, along with your brain, gets vaporized. Which means what comes out the other end isn’t you. It’s an exact copy that the machine made, of a man who is now dead, his atoms floating freely around the interior of the ship.

Teleportation is suicide.
