Time Travel

Categories: Science | Physics
  • Time travel is a theoretical scientific concept that involves sending objects or people backwards or forwards in the time-space continuum. Although it is effectively impossible by the standards of conventional physics, certain aspects of quantum theory suggest that time travel may be a real possibility. Time travel is a popular concept in science fiction.
  • Grandfather Paradox

    The concept of time travel poses a number of philosophical paradoxes about how altering actions in the past may affect the present. One of the most popular is the Grandfather Paradox, which questions what would happen if a time traveler were to go back in time and murder his grandfather. Without his grandfather, he would not have been born. But without being born, he could not travel back in time to kill his grandfather. Mind boggling!
