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.
Light is actually slowing down. At the beginning of the universe, the speed of light AND the speed of GRAVITY were the same. Since then, light has been slowing down while gravity still moves at it's original speed. That speed, THE SPEED OF GRAVITY, is 20 MILLION times faster than the speed of light. So, if you wanted to get to Alpha Centauri in minutes, you need a GRAVITY DRIVE system. I thought you should know.
