A trio of theoretical physicists at the Pennsylvania State University has calculated the upper limit for the possible quantization of time—they suggest 10−33 seconds as the upper limit for the period of a universal oscillator. ...
An international collaboration of scientists has recorded the most accurate confirmation to date for one of the cornerstones of Einstein's theory of general relativity, 'the universality of free fall."
