There is no absolute reality. There is only 'believed' reality. 1. Space Space 'maybe' constituted of innumerable matters, which means space is infinite. However, space exists in ways that we just perceive, which means sometimes, we consider space finite one. That's why I call space as 'infinite finity'. 2. Time The absolute reality is constantly changing, being affected by the time. However, we can't see the flow of the time. Only after detecting something affected by the time, we realize the time.
