The Pros And Cons Of Time Travel

Good Essays

Ever since the release of Doctor Who in 2005, the Tardis has been very iconic throughout the sci-fi universe. Then the question came to mind, is Time Travel really possible? Apart from the fact that Police Boxes are all over the streets of London. However, with technology advancing each and every year and theories being developed and created, it has helped to envisage time travel. Research suggests that, although hard to believe, Time Travel may be possible. Theories such as Einstein’s Theory of Special Relativity, Tipler Cylinders, Black Holes, Cosmic Strings and Time Machines just like the Tardis. They all suggest one thing; Time Travel may be possible. But, how do they?

Einstein says that time travel to the future is possible only if a person or something was able to achieve the speed of light. Realistically, this is physically impossible to do, as the person or object has to have an infinite mass and length of 0. Despite the doubts, two scientists have extended the Einstein’s equations and …show more content…

Time Machines. Time Machines just like the one you see in Doctor Who, Back to the Future, and more recently, Project Almanac. Although, very easy to understand, constructing time machines would be a rather difficult task to accomplish. In order for a time machine to exist, a form of exotic matter will need to be discovered. Exotic matters that possess peculiar characteristics such as a negative energy density or mass. If a matter of this kind were to be discovered, a time machine would bend the space-time continuum backwards until it forms a loop otherwise known as a “closed time-like curve” or CTC for short. Which, essentially means that the time machine follows a path until it reaches a point in space and time that it began at. This means that time travel is possible only towards the future after the machine has existed. These are only a few of the many theories that have been discovered up to
