Shhh! The TSA thinks the terrorists don't know that a clock at altitude appears to run faster than a clock on the ground thanks to gravitational time dilation.

Shhh! The TSA thinks the terrorists don't know that a clock at altitude appears to run faster than a clock on the ground thanks to gravitational time dilation.

Then we'll get all excited and lock the stable door after the horse has bolted. https://secure.wikimedia.org/wikipedia/en/wiki/Gravitational_time_dilation https://secure.wikimedia.org/wikipedia/en/wiki/Gravitational... Remember: If we outlaw clocks, only outlaws will have clocks!
