• TITLE: Causality, Uncertainty Principle, and Quantum Spacetime Manifold in Planck Scale

  AUTHORS: Hamidreza Simchi

  KEYWORDS: Causal Set Theory, Causality, Uncertainty Principle, Kinematic, Manifold

  ABSTRACT: In causal set theory, there are three ambiguous concepts that this article tries to provide a solution to resolve these ambiguities. These three ambiguities in Planck’s scale are: the causal relationship between events, the position of the uncertainty principle, and the kinematic. Assuming the interaction between events, a new definition of the causal relationship is presented. Using the principle of superposition, more than one world line is attributed to two events that are interacting with each other to cover the uncertainty principle. Using these achievements, it is shown that kinematics has no place in the Planck dimension and that quantum spacetime manifold should be used instead.
