text: how much longer will it take to invent teleportation?   how long is a piece of string?  no wait a better reply would be "how ling is a piece of string theory?"  asuming you mean teleportation of acutual objects like a human the answer will be: a long long long while still. if ever.  if you mean quantum teleportation (teleporting atoms and electrons) then it already happened.  side note:  when physicists say "teleportation", they are describing the transfer of key properties from one particle to another without a physical link. - paul rincon bbc news online science staff  using the definition above scientist did manage to successful teleport particles of light over a distance of 600m  as for the pea being teleported. i don't think that ever happened. if it did we would have seen it blasted all over cnn by now. (except maybe if there was some kinda government conspiracy) i mean everybody loves a good conspiracy)  if you need more informaiton do some research on quantum teleportation. some links to news articles.  http://news.bbc.co.uk/2/hi/science/nature/3576594.stm http://www.newscientist.com/article.ns?id=dn1888
