Does time originate in the Dog Mind or does mind originate in Time.  Inquiring dogs wrestle with these questions in their quiet moments.  I've been in deep contemplation for a couple of minutes, trying to solve the mystery of why time moves forward instead of backwards.  I think it might have something to do with dogs and eating.  Doesn't everything?  What would the possibility of time travel mean to us dogs?.  I'm interested in eating my favorite treat, then going back to when it was whole, and eating it again.  It would be like a culinary Groundhog Day with the side benefit that the participant would never gain weight.  I suppose I would eventually tire of eating the same treat over and over again, but its a deep philosophical question in my mind.  There's always a need for variety in a dog's life, and that may be why the arrow of time moves forward. Mind is not interested in the past.  Another proposal is that  the constant ticking of time is due to virtual particles travelling in closed loops becoming real particles, ultimately giving space-time a positive curvature. I've got it narrowed down to one of those two. According to Occam's Razor, when there are two competing hypotheses, the simpler solution is usually correct.  Since dogs are fairly simple, I'm going with a dog's need for new experiences and tastes as the reason we haven't had any Astro's visiting us from the future.  Still, I'd like to take that walk I took this morning over again.  I caught the scent of a rabbit at the corner of Pinewood and Lake Meadow and I wasn't given proper time to investigate.
