In the movie "Back to the Future," Doc Brown builds a time machine into
a Delorean. New research brings that vehicle one step closer to reality.
Look past the details of a wonky discovery by a group of California scientists -- that a quantum state is now observable with the human eye -- and consider its implications: Time travel may be feasible. Doc Brown would be proud.
The strange discovery by quantum physicists at the University of California Santa Barbara means that an object you can see in front of you may exist simultaneously in a parallel universe -- a multi-state condition that has scientists theorizing that traveling through time may be much more than just the plaything of science fiction writers.
And it's all because of a tiny bit of metal -- a "paddle" about the width of a human hair, an item that is incredibly small but still something you can see with the naked eye.
UC Santa Barbara's Andrew Cleland cooled that paddle in a refrigerator, dimmed the lights and, under a special bell jar, sucked out all the air to eliminate vibrations. He then plucked it like a tuning fork and noted that it moved and stood still at the same time.
That sounds contradictory, and it's nearly impossible to understand if your last name isn't Einstein. But it actually happened. It's a freaky fact that's at the heart of quantum mechanics.

"Back to the Future" was the last time America heard the prefix 'giga-' correctly pronounced.
Entertaining article that left much unexplained.
