Time and Space

Is the passage of time a basic feature of reality or merely illusory? How can the present move? Is the past real, or only the present? If the present is durationless, have we any reason to think that our now is the interface between past and future? Is space just nothingness, or is it an entity in its own right? Is there a spatial structure independent of things in space? Are objects separated by spatial relations, although space doesn't exist?
