Well, provided that those "dimension" really can accomodate and sustain human life. Maybe those dimensions are the real "netherworld" or worse.... a void itself. its still death per se (a half glass empty thinking) ... or an eternity of entrapment (a half full thinking, with hope of being saved by fellow humans)

We are fed with too much sci-fi movies that shows the concept of dimension as alternate equivalent of us, but just in different "layers" or "copies", existing in the same timeline. some potrays dimensions as alien world/universe. If the teleportation screwed up, i definitely wont want to end up in their world, dying from their "poisonous" atmosphere (either that, or I'll die choking from their native food they offered LOL)
