senttimetrien

Senttimetrien is a term that appears in speculative discussions and fiction to denote a hypothetical unit of subjective time. It is not an established scientific term and has no formal definition, standard value, or measurement protocol in mainstream physics or psychology.

Definition: In these uses, one senttimetrien (ST) denotes the perceived duration of a standard sensory event under controlled conditions, such as neutral mood and minimal distraction. Because perceived duration varies with attention, arousal, modality, and memory, a senttimetrien is not fixed and can differ across observers and situations. In thought experiments, it helps illustrate the gap between objective time (seconds) and experienced time, including scenarios of time dilation or compression.

Etymology and usage: The coinage blends notions of perception or feeling with time, but there is no universal origin. It has appeared mainly in online discussions and speculative fiction rather than in formal scholarship.

Relation to established concepts: Senttimetrien is contrasted with physical time units and with psychophysical models of time perception. Without a standard definition or measurement protocol, it remains a thought-experiment concept rather than a practical unit.
