In the hit sci-fi franchise Star Wars, a typical method of traveling throughout the galaxy is known as Hyperspace travel. This method of traveling requires two elements: light-speed travel and Hyperspace. Although a product of science-fiction, Hyperspace is an alternative region of space co-existing with our own universe which may be entered in order to induce a notional space-time continuum in which it is possible to travel faster than light.
Starships reach hyperspace by means of a hyperdrive. One famous example of a starship containing a hyperdrive would be the Millenium Falcons (pictured from the cockpit above). Once a starship’s hyperdrive is activated, the ship warps to another dimension consisting of physical laws differing from those within our own universe. One of these differing factors includes the laws of gravity, for it is apparently active within this dimension during Hyperspace travel.
Although the topic of Hyperspace travel is fascinating, current physical laws today prove that it is impossible for any type of physical object to attain that speed. The speed of light is equal to 299,792,458 meters per second. Nothing is faster than light. In order for an object of mass to travel anywhere near this speed, it would require an infinite amount of energy. Even if one was traveling at the speed of light, it would still take thousands of years to travel the galaxy.
Due to the fact that we are still limited by the technology of our time in order to create something which can produce an infinite amount of energy, along with the fact that starships still cease to exist, hyperspace travel would not be able to exist for at least a few centuries.
