Have you ever seen the Back to the Future movies? Where Doc and Marty take the DeLorean DC-12 into the space time continuum. That is like all other time travel, they go back in time to stop something from happening but end up making things worse so they go in the future.
There are two different types of time travel, those are Forward Time Travel and Backwards Time Travel.
Forwards Time Travel: here is no widespread agreement as to which written work should be recognized as the earliest example of a time travel story, since a number of early works feature elements ambiguously suggestive of time travel. Ancient folk tales and myths sometimes involved something akin to traveling forward in time; for example, in Hindu mythology, the Mahabharata mentions the story of the King Raivata Kakudmi, who travels to heaven to meet the creator Brahma and is shocked to learn that many ages have passed when he returns to Earth. A more recent story involving travel to the future is Louis-Sébastien Mercier's ("The Year 2440: A Dream If Ever There Were One"), a utopian novel in which the main character is transported to the year 2440. An extremely popular work (it went through 25 editions after its first appearance in 1771), it describes the adventures of an unnamed man who, after engaging in a heated discussion with a philosopher friend about the injustices of Paris, falls asleep and finds himself in a Paris of the future. Robert Darnton writes that "despite its self-proclaimed character of fantasy...L'An 2440 demanded to be read as a serious guidebook to the future.
Backwards Time Travel: Backward time travel seems to be a more modern idea, but its origin is also somewhat ambiguous. One early story with hints of backward time travel is Memoirs of the Twentieth Century (1733) by Samuel Madden, which is mainly a series of letters from British ambassadors in various countries to the British Lord High Treasurer, along with a few replies from the British Foreign Office, all purportedly written in 1997 and 1998 and describing the conditions of that era. However, the framing story is that these letters were actual documents given to the narrator by his guardian angel one night in 1728; for this reason, Paul Alkon suggests in his book Origins of Futuristic Fiction that "the first time-traveler in English literature is a guardian angel who returns with state documents from 1998 to the year 1728", although the book does not explicitly show how the angel obtained these documents. Alkon later qualifies this by writing, "It would be stretching our generosity to praise Madden for being the first to show a traveler arriving from the future", but also says that Madden "deserves recognition as the first to toy with the rich idea of time-travel in the form of an artifact sent backward from the future to be discovered in the present.
As we advance more in technology the possibility of us being able to travel through time becomes more and more real. Pretty soon we will be able to send out packages through wormholes and never have to wait for them through the mail. Time travel, wormholes, they all have amazing possibility's and uses but the hard part is getting them to work for us not against us. One day we will be able to warp through time and space and I hope that I am alive to witness at least the start of time travel.
