Lightest Tripod Ever

Summary: High precision measurements require optical elements to be super-duper stable to researchers has proposed using light beams reflected off of three mirrors to suspend a fourth mirror in the air to be used in measurements. It sounds crazy until you remember that (A) the suspended mirror is only two millimeters in diameter and (B) the reason this might be possible is quantum mechanics so of course it sounds crazy.
