A wormhole also referred to as Einstein-Rosen bridge describes a hypothetical topological spacetime feature, which is essentially a shortcut linking one point of the universe to another. The wormhole allows travel between the two points to be faster compared to what it would take light to complete a journey via normal space.
The term “wormhole” stems from an analogy that was employed in an explanation of this thinking: an imagination of an apple skin as the universe, and a worm traversing over its surface (Morris and Kip 398). The distance from one point of the apple to another point equals half the circumference of the apple, that’s if the work sticks on the surface of the fruit. However if the worm rather directly burrows a wormhole through the apple, the distance for travel is reduced considerably.
