The ruler length and width measurements reflected the largest bias, regardless of wound shape [8]. The standard error of measurement (SEM) is defined as the difference between an observed score and a true score, so the SEM is an indication of the imprecision of a measurement technique [17].
Washington: Runaway planets zipping through space at mind-numbing speeds of 30 million miles per hour are now the fastest objects in the universe, says a study. Seven years ago, the discovery of the first runaway star, shooting out of our Galaxy at a staggering speed of 1.5 million mph, set astronomers on a course of exploration.
For objects with mass, speed can only be measured in relationship to something else. In that case, the fastest measured object in the universe has been the Oh-My-God particle, which was traveling at ~ 99.99999999999999999999951% of the speed of light when it impacted our atmosphere.
