Chronokinesis is the hypothetical ability to manipulate time. This concept often appears in science fiction and fantasy, where characters can speed up, slow down, or even reverse the flow of time. While it is a popular theme in various media, there is no scientific evidence supporting the existence of such powers. In literature and film, characters with chronokinetic abilities may use them to alter events, avoid danger, or gain an advantage. Examples can be found in works like Doctor Who and The Flash, where time manipulation plays a crucial role in the storyline and character development.
