What is time travel?

Time Travel

Time travel is the concept of moving between different points in time in a manner analogous to moving between different points in space. Time travel could hypothetically involve moving backward in time to a moment earlier than the starting point, or forward to the future of that point without the need for the traveler to experience the intervening period (at least not at the normal rate). Any technological device – whether fictional or hypothetical – that would be used to achieve time travel is commonly known as a time machine.

Famous quotes containing the words travel and/or time:

    Yes, but I do not travel to find comfortable, rich, and hospitable people, or clear sky, or ingots that cost too much. But if there were any magnet that would point to the countries and houses where are the persons who are intrinsically rich and powerful, I would sell all, and buy it, and put myself on the road to-day.
    Ralph Waldo Emerson (1803–1882)

    This is no time for sentiment. This is war.
    Dudley Nichols (1895–1960)
