Abstract
Quantum Theory has created new perspectives on reality in the human mind. The fact that the micro-world has different identities than the macro-world, as it emerges with Quantum Theory, has made the subject of reality, which underlies everything, more complex. Quantum Theory has demolished the deterministic world view drawn by classical physics, revealing a reality of reality. In addition, it has brought up new questions about customary laws to date, including logic rules because of the peculiarities of the electrons, which appear to have multiple characteristics at the same time. Absurdism is the philosophical view based on the confrontation between the human's aspirations and the desire for happiness and the indifference of the world. The absurdism considered in existentialism that emphasizes subjectivity, although it is based on Sören Kierkegaard, was identified with Albert Camus. The absurdity of Albert Camus was the basis of his philosophy. In this study, it will be examined whether the characteristics of quantum theory, which are evaluated as strange, support absurdity. For this purpose, firstly Quantum Theory and its scientific results, which were evaluated as strange, were revealed. Later, existentialism, absurdity of Albert Camus, and the absurdity of Jean Paul Sartre, explained the relationship of Quantum Theory with these views.
