A paradox is something that seems to be a contradiction or which appears absurd but which is actually true or factual. There are a variety of paradox quotes to browse through and some of these are very entertaining and amusing. The word paradox can also be used to refer to someone or something that has traits or features which seem to contradict each other. Many believe that time travel could cause a paradox situation if you travel to a time when you were already present, or if you travel back and interfere with important events that have occurred in your life up until that point. When something is a paradox it causes an enormous amount of interest because it seems to be a pairing of contradictions that should not exist or happen.
