Well, it’s a trick question, because I don’t even HAVE a green t-shirt.

In a crazy alternate universe, where I did own a green t-shirt and where I stepped into my mystical time machine and simply prevented my previous self from purchasing this jade garment… then what colour t-shirt would I be wearing then?

Also, I wonder… would it morph slowly, like one of those heat-reactive things from the 80′s? I hope not, because that would mean that there is such a thing as Time Memory, which I just made up, but now have to copyright in case Showtime decide to make a TV programme of the same name and I have to sue them for damages. This Time Memory that I profess wouldn’t be a past memory, but a memory of the future. If my t-shirt just jumped colour without involving any Time at all, it would make sense to the current way we generally see time; as this linear object travelling in a single direction.

In Back to the Future, this morphing/fading stuff happens a lot; in a photograph, or when Marty McFly starts to vanish on stage mid-Earth-Angel. Theoretical or not, this concept would be an alpha-transparency of two alternative universes, happening simultaneously in the same place, based on something that happens in the future. So Time would have to know about this event, and possibly all events. Which leads us to a very important question;

If Time was to know everything that will ever happen, do you think that it would act in the opposite way that we do, in that it could never remember anything in the past?
