The lecturer's PhD thesis [11] is based on one of these logical approaches 2002 [2], [6]. Till 2011, he and some other logicians made an unsuccessful aƩempt to shed light on this problem in this way. In 2010‐2011, he started to introduce another logical approach based on paradoxes, more specifically ?Unexpected Hanging Paradox?. The goal is to use paradoxes similar to applying paradoxes (Liar Paradoxes) in the Godel?s Incompleteness Theorem [14], [15], [16]. In [5], [16] (2017), he showed by defining a new version of this paradox, we face a contradiction, not a paradox. To cope with this situation, in 2019 Fuzzy Time [4], [17] (or as some of the speaker?s colleagues used it later on, Temporal Continuum (2023) or Continuity in Time (2024)) came into the centre of the subject and discussion. Nevertheless, we have concepts similar to the fuzziness of Time and space in the history of science, Mathematics, Philosophy and Physics [7], [12], [13]. Based on that, the speaker claimed a new interpretation of Quantum Mechanics, the ?Fuzzy time‐particle? interpretation of Quantum Mechanics [1], [3], [4]. ?Theory of Fuzzy Time Computation?, is introduced in [8], [9], [10], monthly seminars of the Iranian Association of Logic [18], and The 10th annual conference of the Iranian Association for Logic (IAL) (2023) [19]. In 2023, this Theory was introduced in a paper in HAL [9] and now it is in development. In this lecture, after defining this Theory, we explain a part of it in details, and as the main conclusion, we prove TC+CON(TC^* )ͰP≠NP.
