Time traveling

D.C. War Memorial, Washington, D.C. (Memorial honoring the 26,000 D.C. citizens who served in World War I.)

Time is not a line but a dimension, like the dimensions of space.  If you can bend space you can bend time also, and if you knew enough and could move faster than light you could travel backward in time and exist in two places at once.

~ Margaret Atwood, Cat’s Eye
