On the Nonexistence of Time

Time has never been physically proven or discovered. Nevertheless, time has been presupposed as real in physics, philosophy, and everyday language. This paper does not propose a new definition of time but aims to deconstruct the structure of the phenomenon called time and reveal its true nature through logical description.The core of this paper is as follows. First, the activity of the mind gives rise to time. Second, without duration there is no time, and without interval there is no time. Third, change exists, but time does not. Fourth, speed as change exists, but speed as time does not. Through these distinctions, this paper classifies psychological time (derived from duration), functional time (derived from interval), and time derived from associative operation, and identifies the structural problem of existing disciplines conflating these categories.
