"A Wrinkle in Time" comes true..... Check this out, from a post on BoingBoing about physicists, invisibility cloaks, and a space-time invisibility cloak. How cool would this be? (One more reason to have studied my science lessons more carefully in Elementary School...)
"Lasers would be used to control the fibres' refractive indices, opening and closing the temporal void. The fibre-optic cloak could hide events only from observers standing directly ahead of the oncoming light waves, and it could not fully block all reflections from light travelling through the cloak while it is turned on, so some light might bleed out. A distant observer looking down the optical fibre would not spot the hidden event, but they would notice the background light getting brighter and dimmer. McCall hopes that a fibre-optic cloak creating a space–time void around 30 centimetres long, to hide actions taking place over a few nanoseconds, could be built within the next year." (BoingBoing)
I want one of those in a user-friendly pocket-pack, please....
