Ultimate spaceships

Ultimate spaceships or doomsday ships are lightspeed ships sent by the new world to reach the end of the universe and have no destination at all. They turn their curvature engines to maximum and accelerate, infinitely approaching the speed of light. Their goal is to leap across time using relativity until they reach the heat death of the universe. By their calculations, ten years within their frame of reference would equal fifty billion years in the universe. In this way, the passengers can reach the end of the universe within their lifetime.
