Paradox

What does paradox mean?

It is a statement that appears to be self-contradictory but may actually be true. A logically valid argument based on premises that are generally accepted as true, yielding either a contradiction or conclusion that conflicts with other generally accepted beliefs. For example:Such paradoxes include the Grandfather Paradox, a famous theory that denies the possibility of time travel, stating that if you went back in time and killed your grandfather, you would phase out of existence. However, this could not have happened, if you did not exist, you could not have gone back in time and killed your grandfather. This is an example of how paradoxes work, generally ending in an eternal loop that is not plausible within the currently known laws of physics.
