Time Travel and How Black Holes make it Possible “Man… can go up against gravitation in a balloon, and why should he not hope that ultimately he may be able to stop or accelerate his drift along the Time-Dimension or even turn about and travel the other way” (Wells). In this quote, H.G. Wells asked one of the most commonly asked questions in time travel, why can people not move about in time as they wish? Black Holes present the opportunity to move forward in time although not in the same way as the “time machine” of popular science fiction. Time travel via black hole is completely uncontrollable, extremely dangerous, and won’t even be able to take you very far into the future. Another way of traveling through time is through wormholes, …show more content…
Wormholes are theoretical tunnels through space and time that exist in the quantum foam and are just a billionth-trillionth-trillionth of a centimeter across. They link two different places and two different times. Some scientists believe it could be possible to capture one and enlarge it trillions of times in order to allow a person to go through it. Theoretically, these wormholes would connect either distant regions of a universe, or they could connect our universe with another universe. However, in order to keep the throat of the wormhole from collapsing in on itself, you would need large amounts of negative energy; of which we have only been able to produce very small amounts with the Casimir effect. Despite the fact that wormholes look very promising to Science Fiction enthusiasts, the fact remains that it is unclear whether or not wormholes even exist, and even if they did we would need to be able to enlarge the wormhole and be able to produce large amounts of exotic mass to stabilize
