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.
From its shape to its satellites, Haumea is a strange object, but one that could shed light on the history of collisions in the solar system, as well as the early environment of the Kuiper belt, which sits out beyond the orbit of Neptune.Fastest spinner.aumea is the fastest spinning object in the solar system. The object's odd shape is a direct result of the spin. Because of this spin, it pulls itself outward at the equator in a bulge, Brown explained. The Earth has a less pronounced version of this bulge for the same reason.
