"Even a stopped clock tells the right time twice a day."i believe that "time" as we perceive it, (ie, linear, going forward, 60 seconds per minute, etc) only exists so that we can keep track of things in our heads and to make things less confusing. however, i believe that time is multi-dimensional, and ever-flowing. is is not merely a straight line, but more like a sphere.
stephen hawking (among other physicists) has said that time and space cannot really be separated. past, present, and future happen simultaneously. enlightened ones might sometimes know the future by remembering it.
