I was just scanning the science section in the old Huffingpaste, when I came across this gem of a headline: Why Does Time Move Forward? I am not going to link to the article, and I didn’t bother reading the article, because hey, come on, really.
Time moves forward because if it moved backward then we would call that forward and, in fact, that might be the case. You only can relate to your own environment and we are stuck in this one, moving the way that time moves in this universe.
If there were some sort of Merlin/Benjamin Button/the Jonathan Winters character in Mork and Mindy effect going on, then it would seem perfectly natural to us and that’s how we’d relate to it.
But I think we can go a step farther. As Descartes said “I think therefore I am,” so it follows that not only can we trust our basic sense of existence as proof of existence, so we can trust the evidence of our senses that the universe around us is, at least in the ways that affect us, more or less as it seems. Flowers bloom in the spring, the dawn precedes the day, we are small when we are born and get a bit older every day.
So, time is moving forward. Which is exactly what we demand of it.
