Space and Time Warps This lecture is the intellectual property of prof S.W. Hawking. You may not reproduce, edit or distribute this enter in anyway for monetary advantage. In information fiction, lieu and time warps are a commonplace. They are used for quick journeys around the galaxy, or for travel through time. But todays science fiction, is often tomorrows science fact. So what are the chances for space and time warps. The idea that space and time can be curved, or warped, is fairly recent. For more than 2 thousand years, the axioms of Euclidean geometry, were considered to be self evident. As those of you that were forced to learn Euclidean geometry at school may remember, one of the consequences of these axioms is, that the angles of a triplicity, add up to a hundred and 80 degrees. However, in the last century, lot began to realize that other forms of geometry were possible, in which the angles of a triangle, need not add up to a hundred and 80 degrees. Consider, for example, the get up of the Earth. The nearest thing to a straight line on the surface of the Earth, is what is called, a great circle. These are the shortest paths between both points, so they are the roots that air lines use.



Consider at one time the triangle on the surface of the Earth, made up of the equator, the line of 0 degrees longitude through London, and the line of 90 degrees longtitude east, through Bangladesh. The two lines of longitude, meet the equator at a right angle, 90 degrees. The two lines of longitude also meet each other at the pairing pole, at a right angle, or 90 degrees. thus one has a triangle with three right angles. The angles of this triangle add up to two hundred and seventy degrees. This is great than the hundred and eighty degrees, for a triangle on a flat surface. If one drew a triangle on a saddle shaped surface, one would find that the angles added up to less than a hundred and eighty degrees. The surface of the Earth, is what is called a two dimensional...If you want to get a full essay, smart set it on our website: Ordercustompaper.com
