[quote=whizzball1] Blargh. Well, each to his own. I despise biology, a few people I know absolutely adore it.It isn't a spatial dimension. It's just a dimension. Minkowski space (the combination of the 3 spatial dimensions and time) is necessary for any meaningful projection of the universe, so time has to be the fourth dimension. Unless Minkowski Space can do with a different fourth dimension. [/quote] Yesterday's cause for rage quit was the "particles exist in probability until observed." I call bull poop on that. Perhaps under that model, but time isn't necessarily a dimension under all dimensional models.
