Time is not a line but a dimension, like the dimensions of space. If you can bend space you 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.
Certain redwood groves are holy places for me because they capture silence and light. The forest is so dense as to exclude all external noise. It is possible to ignore their silence until a single bird sings within. When the single song has died not only do I realize I have heard a sound exquisite in its simplicity, but also that I have heard it so precisely because it was embedded in pure silence.
