It's always been a puzzle to me about what makes time different from other dimensions. In the article, it mentions that Lanza has "a theory that space and time are constructs of biological sensory limitations." This implies that by shifting the dimension that the biological systems run along, you can either change the dimension considered "time," or even reverse the direction. I'm not sure this is possible, though, because of entropy. Movement along any directional dimension doesn't determine the position or reversibility of chemical or physical processes, but movement along time does.
