The Cosmological 10¹²² Problem and Vacuum Energy as a Constraint on Degrees of Freedom in the Q-Field

Version 2: Expanded framework including cosmological implications and improved conceptual structure. The cosmological constant problem represents one of the largest discrepancies in modern physics, with a difference of approximately 10^122 between the vacuum energy density predicted by quantum field theory and the value inferred from cosmological observations. In this work, this discrepancy is interpreted as an overcounting of vacuum degrees of freedom rather than a fundamental failure of the theory. Within the Q-field framework, a structural constraint is introduced that limits the number of physically accessible modes. It is shown that the number 10^122 naturally emerges as the maximum number of degrees of freedom of the observable universe, consistent with holographic scaling. This leads to an effective suppression of vacuum energy that matches the observed cosmological constant. This proposal is presented as a phenomenological interpretation, providing a possible connection between vacuum structure, spacetime degrees of freedom, and dark energy.
