PST
n. uncountablen. a way of looking at time where the past, present, and future are all equally real and exist at once. It is a concept used in science and philosophy to talk about how time works.
n. the conceptualisation of time as a four-dimensional block where past, present, and future events are equally real. Often discussed in the context of the 'block universe' theory in physics and philosophy.
The theory of PST suggests that the past still exists.
In his lecture on the philosophy of time, the professor compared PST to a film strip where every frame exists simultaneously.
Adopting a PST perspective allows physicists to treat time as a geometric dimension, effectively removing the subjective 'flow' of time that humans experience in daily life.
Often used as an acronym for 'Past-Present-Future' or 'Present-Sentient-Time' in specific academic frameworks; typically appears without an article when referring to the abstract concept.
