In a breakthrough experiment, Aaron O’Connell has blurred that distinction by creating an object that is visible to the unaided eye, but provably in two places at the same time. In the following video presentation he suggests an intriguing way of thinking about the result.
I thought that O'Connell gave a good background on the problems he was studying and what his results were. I admit that the problems he explained that always bothered him about Quantum Mechanics have always bothered me. Of course his findings brings up more questions than it answer - one of the things I love most about since.
It is exciting because such research can lead to true technology previously dreamed of on Star Trek - Faster than light travel, matter/energy transportation, and matter replication. All kinds of doors are open.
