Usually time in our universe is considered approximately linear after the Planck time, t*, and undefined before it. How time behaves in the region of uncertainty, and even before zero, is a subject of contention. I propose that the Planck units in general demarcate spherical boundaries of symmetry. In the case of time, such a reflection at t=t* of all actual (virtual) events from t*-->infinity maps onto virtual (actual) events from t*-->0. This duality between real and virtual spacetime parallels the Higgs potential's "true vacuum" (here the familiar t* is transformed into t=0), and also its "false vacuum" (here the familiar extrapolated t=0 is transformed into t-->-infinity). This correspondence limits our temporal experience to time oscillating between the Planck and Hubble regions (or their anti-symmetry). Forever compounding this mirroring within our finite observable cosmos, there is sufficient room for infinite and infinitely curved time. My website (below) gives many other applications of "inverted space."
