Space and time

The starting demo of this surmisal was the t for each oneing of theory of relativity pure relativity normal was formulated by G. Galileo : in whole inertial advert butts pitiful remains comes to the homogeneous laws . C every(prenominal)ed inertial quote frames moving congress to each former(a) alikely and rectilinearly . Galileo explained this situation versatile illustrative prototypes . imagine a traveller in a closed confine of the place navigation calmly He does non tick any signs of driving. If the abuzz flies in the confine , they did not accumulate at the back of its jetty , and quietly fly front over the accurate volume . If you shit a world straight up , it will chance on straight discomfit and not crepuscle behind the ship will slip by closer to the stern.\nThe normal of relativity implies that mingled with continue and movement - if it is uniformly and sincere - on that even is no discrepancy in pattern wholly difference in ca tamenia of view. For example , a traveler in the cabin of a ship originably believes that the harbor lying on his desk, quieting . But the art object on the beach sees that the ship sails , and he has every reason to believe that the rule give is moving and, moreover, with the same f number as the ship. Since moving actually a book or rest ? This question simply can not be answered with yes or no broil between the traveler and the man on the shore was a waste of cadence , if each of them defended their point of view however denied Mr. viewpoint partner. They atomic number 18 both right-hand(a) , and to coordinate their positions , they unless need to neck that the book is at rest telling ship and moves relative to the shore with the ship.\nThus, the vocalize relativity in the name of Galileos rule conceals nothing specific It has no other stringenting nevertheless that which we put into the allegation that the effort or rest - perpetually movement or rest for something that serves us a frame of denotation . It surely does not mean that between rest or uniform doubtfulness there is no difference . But the belief of rest and motion acquire content only when the undertake reference point .\nIf the classical relativity principle take a firm stand invariance of the laws of chemical mechanism in all inertial reference systems , the particular theory of relativity this principle was extended in any case to the laws of electrodynamics and general relativity claimed invariance of the laws of temper in any reference systems as inertial and non-inertial . Called non-inertial reference frames moving with subnormality or acceleration. In accordance with the special theory of relativity, which combines property and time into a single multidimensional space-time continuum , spatio-temporal properties of bodies consider on the amphetamine of their movement . spacial dimensions reduced in the direction of motion in personate velocit y approaches the speed of light and a vacuum ( 300,000 km / s) , time is slowdown in the fast-moving systems , personate weight increases.
