Relativity says that time is an aspect of space, and space an aspect of time, right?
So we've evolved to live a certain length in years, and occupy a certain space. In terms of the speed of light it's fair to say that the distance light can travel over our lifespan is magnificently huge compared to the amount of space we occupy (Seventy light years, rather than a metre, give or take, in any given direction).
Bear with me: through evolution we've achieved a certain complexity, and that complexity gives us awareness. Without the complexity, there'd be no life, no us. The complexity is the important thing.
So what I'm wondering is, what if the ratio of dimensions, time to space, is reversed? Over a huge space, but a fraction of time, similar levels of complexity exist to those that make up who we are. Given that particular complex states might exist for fractions of a second, located over billions upon billions of cubic metres of space, it would be challenging to perceive their existence, focused as we are lengthwise through time. But by what criteria could we argue that they were not alive? Aware? Even, acting in and upon the same universe as we are?
Hmm. Potentially freaked :)
