A spacetime mirror is a hypothetical construct in speculative physics and science fiction that reflects not just the three spatial dimensions but also the time dimension. Unlike a standard 3D mirror, which reverses light rays along an axis perpendicular to its surface, a spacetime mirror would reverse along a hyperplane perpendicular to 3+1 spacetime dimensions. The concept serves as a thought experiment to explore the complexities of higher-dimensional spaces and the nature of time.
In the sci-fi novel, the characters used a spacetime mirror to reverse the events of the past and alter the future.

Post-Spacetime is a hypothesis and a stance that holds that there are things beyond spacetime and that those things should be studied and explored, often seeking on the exploration of what's beyond spacetime and seeking on develop means to study what's beyond that. Furthermore, post-spacetime can also refer to the idea of superation of the spacetime and to evolve humanity into a post-spacetime civilization and societies who lives beyond spacetime. Post-spacetime also supports theories such as extraterrestrials exists beyond spacetime and they already created means to exist and live beyond spacetime and it also holds that extraphysics and extraphysical mechanics might be useful to explain what's beyond spacetime and that being extraphysical means being beyond spacetime. Where extraphysical life, extraphysical civilizations and extraphysical societies are life, civilizations and societies that exist beyond spacetime and that extraphysicalism and extramaterialism are philosophies that deals with what's beyond spacetime, and where spirituality, religion, esoterics and occultism are forms do deal what's beyond spacetime and they might be useful to explain what's beyond spacetime. Post-spacetime also holds that multiverses and other dimensions exist beyond spacetime and that's the why it's literally impossible to detect them, also supporting epistemological pluralism in order to study what's beyond spacetime.
"The post-spacetime hypothesis is really great, sadly it might take some time until become mainstream, but while it doesn't happen, it's just develop it even more for become mainstream itself."

Post-Spacetime Civilization is a name of a kind of civilization that managed to overcome the spacetime amd managed to exist beyond spacetime, literally becoming an extraphysical civilization. Post-spacetime civilization is a kind of extraphysical civilization, since it exists beyond spacetime and it managed to overcome the spacetime somehow, mainly by technology or by spirituality, and it exists at extraphysical level, both terms can be used to refer to extraphysical civilizations beyond spacetime, but post-spacetime civilizations managed to overcome spacetime, while extraphysical civilizations simply exist at extraphysical level.
"The concepts of post-spacetime civilization and extraphysical civilizations might be really useful in order to explain the existence of aliens and intelligent life beyond Earth as well, but it might take some time until those ideas become mainstream, together with extraphysical mechanics, bioextraphysics, psychoextraphysics, neuroextraphysics, extraphysicalism, post-spacetimeism, spiritualicism, deistology and ideas related to them."
