Relative scheme - Essay Exampleearth-bound existence) can be regarded as tenable. This gave rise to a controversy because in perfect mechanics a free f tout ensemble in a non-gravitational field is known as inertial motion, i.e. there is no external force applied on the object. But gravity is a force. Therefore, classical mechanics holds the view that inertial objects moving through space can non accelerate with respect to from each one other.Now we come to the crux of the problem how to reconcile the two ostensibly incompatible a priori postulates? Einstein next proposed an alternative theory in which he argued that the space-time continuum is curved. His subsequent field equations interrelate the curvature of space-time to the mass, energy and the momentum within it. Hence his famous equationNow I willing come to the point in the article. So called Grandfather paradox is directly related to the equal traveler-homebody paradox here. Since space-time curvature as suggested by Einstein would allow us to solve the seemingly irreconcilable twin paradox presented in this article, it might be pertinent here to examine all probabilities of the theory. According to the Grandfather paradox a time traveler who goes back in time will be able to kill his biological granddad before the latter meets the time travelers grandmother so that one of his parents might not be conceived. Logically, this means that he himself might not be born. Now comes the real paradox. Since the time traveler did not go back in time, his grandfather was not killed. Therefore one of his parents was born thus enabling him or her to meet the other. Finally, the time traveler was born.The homebody finds out to his amazement that his brother is now four years younger than him. The logical chronological sequence of events should provide an equally logical outcome. Now lets look at what the Doppler effect has to hug drug us by way of an explanation. According to the Doppler effect waves that propagate in a
