Omg dvdhamlyn and fronthead and Dopefish666 just SHUT UP!!! We all know this not gonna work for so many reasons but don't spoil our imagination morons!!! It's not about working it's about believing in it!! Religions don't work,you can't explain them but i bet you all believe in something(even if you 3 stupid cunts don't believe then 96% of world population does) so SHUT UP and just imagine if you could see someone in a different block lol like see a bus and hurry because you know it's already arrived or see a girl you will instantly fell in love with and searching for where the other mirror exit to so you can find her.Don't be so logic,fantasy is required if you wanna live a happy life! This is exactly what is wrong with our generation and the today's world: too many information (because of internet and media)so everyone thinks he or she is an omniscient!!!!! You don't know ANYTHING by your empirical evidence(that's what you get from your previously own experience so you won't lose 15 seconds googling it and read what Wikipedia says about it you lazy ass!)everything you know is what you read or what others told you so don't play it mr wise lol and that CAN work!!!! you would be dumb if you say it wouldn't work on any circumstances i mean it's sure is difficult but it's not impossible you just need a plan about how the physics of this experiment will work along the way!!! Trust your soul because sometimes brain lacks of imagination so brain cannot act spontaneous while heart can!
