The terms curved time, curved space, and curved time-space are commonly used in science fiction. They sometimes refer to Einstein's theory in that time and space form a continuum that is folded, folded, or warped from the observer's point of view, in relation to factors such as movement or gravity, but are also used in to more fantastic notions regarding discontinuities or irregularities in space-time, not based on real-world science. According to Einstein's theory of general relativity when a mass body "m" and "volume" (each length of "l") moves with a speed "v", then many changes take place in the physical aspect . Its length decreases and the mass increases. These factors remain in increase and decrease with the increase in speed. When the body reaches the speed of light "c", the length becomes zero, becomes infinite mass and the time factor fades. In other words, there is no time within the event horizon of the moving body. In this way, the body sometimes takes irregular shapes and covers distances of millions of light years in zero time, because the passage of time for that mobile has disappeared. During this process, the body is said to move with a temporary deformation speed.
