I was also wondering why the slowing of time or change does not work in reverse, is there any way to speed up "time" other than simply going faster and getting somewhere quicker... I cannot seem to think of any, these crossed my mind and made me laugh at myself: Slow a spacecraft down to a millionth of a millimeter a year speed and see if it speeds up time, Or, fly backwards at the speed of light... No one wants to do that anyway, well, unless you have a long jail sentence...
