Is Lorentz Contraction Real? In several recent pedagogical papers, it has been clearly emphasized that Lorentz contraction is a real, physical deformation of a uniformly moving object, a phenomenon that exists regardless of the process of relativistic measurement by the observer [5,6,7]. Is length contraction and time dilation real? Yes, they most certainly are. They
How Fast Would Santa Claus Have To Travel? They assumed a travel time for Santa Claus of 12 hours, although taking into account time zones and presuming he travels from east to west, he would have an additional 24 hours to complete the task. Using these figures, Santa Claus would have to travel at a
How Fast Must Santa Travel On Christmas Eve? At least, not compared to relativity and the speed of light. To move that 0.205 mile (0.33 km) average distance from house-to-house, assuming a time of 150 microseconds (which is half the total time he’s allowed at each house), Santa need only travel at around 1,367 miles-per-second
