Traveling in space might be a lot of people’s dream; however, very few make it that far. The distance required to reach space might be difficult and may take years and years. Nuclear power at a speed of 4.5 percent lightspeed is said to be the fastest as yet.
Because of this, many science fiction writers have come up with five faster-than-light examples of starships. Let us look into the details :
1. Einstein- Rosen Bridges
Einstein-Rosen Bridges resembles wormholes and is one of the most common types of interstellar travel. As per Einstein’s theory of general relativity, some bridges exist through space-time. The bridges make it possible to connect two different points in space-time, allowing creating a shortcut. With the wormhole technology, it is now possible that the spacecraft makes an entry and exit at sub-light speeds. Further, the spacecraft is the best fit for any fictional plot to reach between distances in no time. Einstein-Rosen Bridges seems to have the highest likelihood of existence.
2. WARP Engines
The warp technology is another engine that seems to be adventurous and makes possible faster space travel. The warp engine can bend the space and expand itself. The technology made humans capable of doing the spacefaring races like the Vulcans in the movie Star Trek: First Contact. However, the only drawback of this technology is the high amount of energy that it requires. The reality of warp engines seems impossible.
3 . Hyperdrive
Hyperdrive allowed the entry of vessels to the hyperspace, making it possible to cover distances in space faster. A majority of ships that featured in Star Wars were all equipped with hyperspace drives. Some of the examples include Poe Dameron’s X-wing and Millenium Falcon. However, when compared with the above two, hyperdrive seems to be impossible. The reality of the hyperdrive appears to be far from the truth.
Jumpdrives seem to be way ahead of the above engines and cause no delay while traveling. In-depth calculations before and during the jump are required to prevent the ship from materializing close to the planet. However, the application of Instantaneous teleportation is something that rarely happens in reality.
5. Closed Time- Like Curves
Doctor Who, made use of a big blue box named TARDIS, (Time and Relative Dimension in Space) that could take them anywhere and anytime. A closed time-like curve is a bubble of spacetime, allowing the traveler to go anywhere as per their timelines without affecting the time inside the bubble. Though the TARDIS appears to be magical, its reality seems to be a question mark.
