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.
1. The Big Bang itself expanded much faster than the speed of light. But this only means that nothing can go faster than light.. Since nothing is just empty space or vacuum, it can expand faster than light speed since no material object is breaking the light barrier. Therefore, empty space can certainly expand faster than light.
