ABSTRACT
This chapter focuses on some influential lines of argument that attempt to draw very significant conclusions about the nature of time from the distinctive spacetime geometry of STR. Newtonian physics can be formulated as a spacetime theory. Presentism thus collapses into solipsism of the most extreme sort: other than this spacetime point nothing is real. In Tooley's modified theory, light has different speeds in different inertial frames. In 1935 Einstein, Podolsky and Rosen (EPR) came up with an ingenious argument designed to show that quantum mechanics, at least in its orthodox form, cannot provide a complete description of nature. Bohm's theory and orthodox collapse theories seem to require the postulation of some preferred set of hyper planes, ruining Lorentz invariance and jettisoning the fundamental ontological claims of the Special Theory. Hostile to the idea of superluminal 'spooky' action-at-a-distance, this is the option that EPR preferred. And hence their conclusion: quantum mechanics cannot provide a complete description of nature.
