So apparently scientists have been able to move tiny objects (the size of a bacterium) a few millimeters for years now using what they call “optical tweezers.” But a new technique allows them to move much bigger objects a meter or more. Can they use it to pull the shit out of my pants? Only time will tell.
The device works by shining a hollow laser beam around tiny glass particles. The air surrounding the particle heats up, while the dark center of the beam stays cool. When the particle starts to drift out of the middle and into the bright laser beam, the force of heated air molecules bouncing around and hitting the particle’s surface is enough to nudge it back to the center.
A small amount of light also seeps into the darker middle part of the beam, heating the air on one side of the particle and pushing it along the length of the laser beam. If another such laser is lined up on the opposite side of the beam, the speed and direction the particle moves can be easily manipulated by changing the brightness of the beams.
First anal probes and now this? Science is really something. How long before this apparatus can be strapped to your wrist for force grabbing? That would really be awesome. Unfortnately, it can’t happen because that tightass George Lucas will slap a suit on its makers faster than you can say “I am your father.”
