A Quantum-Mechanical Mechanism for Reducing the Cosmological Constant

Understand

We exhibit a mechanism which dynamically adjusts cosmological constant toward $0^+$.

• The adjustment is quantum-mechanical, discharging cosmological constant in random discrete steps.
• It renders de Sitter space unstable, and triggers its decay toward Minkowski.
• Since the instability dynamically stops at $\Lambda = 0$, the evolution favors the terminal Minkowski space without a need for anthropics.
