We have already spoken about those who feel the internet has become our collective past a sort of virtual memory for all of us. I think that an interesting thought but am fascinated by the conclusions that one can draw from this line of reason. One of the interesting aspects of the possibility of time travel is to go back to the past and revise our history to change our future what is sometimes known as the Grandfather paradox. Before when we relied on print and solid materials it was not difficult to go a primary source- the facts were generally agreed upon but the interpretation of them could be up for discussion. Now if the internet is our collective past then isn’t it possible to go back and revise it with just a few key strokes are we not creating a constantly shifting past to create the reality that suits our needs? Remember the incident where Sara Palin said that Paul Revere “warned the British that they weren’t gonna be takin’ away our arms.” While the news media rushed to point out that Revere was, in fact, warning the American colonists, not the British, Palin’s supporters apparently attempted to update the Wikipedia entry on Revere in order to make the facts conform to Palin’s version of history. While the nature of the 24 hour news cycle caught this incident, how many other changes could be made with out our notice? How do we know that our past is really our past or something made up for us for if one can control the past can one not also control the future and while not a time machine to travel through time it does seem like the ability to influence a future to your desire.
