While in college, I wrote a paper about the unity of space and time. The idea is that time is just a dimension like width, length, and height. Duration is not different than displacement. The obvious challenge is that time sure seems different. But perhaps, college student JimII continued, time only seems different because we are human. Our powers of perceiving spatially are limited to three dimensions, thus in order to experience everything around us, we experience it as a sequence. Perhaps motion, cause-effect, all of it is a human construct. You do lose free will, though not the perception of free will, but still a downer.
I've fiddled with this stuff every once in a while. I've come back to it several times during this period when my life has been so touched by death. I find it strangely comforting. I think because it suggests that the past is real. That the idea of time passing away, is just a convention, like the idea that the earth is motionless. Sure, you have to live your life assuming the earth is motionless and fixed, but it really is not.
It also feels kind of juvenile to find comfort in such things. But, I don't guess it makes sense to judge what brings us comfort. We judge also most everything we do: our work, how we spend our money, how we raise our children, work on our marriage, how we eat. Seeking comfort should probably be done without judgment.
