Dark Matter and Dark Energy are Quantum Vacuum?

Our aim is to utilize quantum vacuum effects to address both the missing mass problem and the cosmological constant problem. Drawing inspiration from the concept of entropic gravity and noting the thermodynamic phenomenon of attraction between two cold objects, we put forth a conjecture regarding the origin of gravity. From this conjecture, both gravitational and inertial forces naturally emerge. Under this framework, the acceleration of objects depends on the distribution of mass and energy in the universe, thereby providing a solution to the source of “extra” gravity. Moreover, this approach offers an explanation for the observed variations in galactic rotation curves under different external gravitational field strengths. By the end of this work, we present a physical picture that addresses the cosmological constant problem, attributing dark energy to vacuum effects as well. In doing so, we propose the quantum vacuum as a viable candidate for both dark matter and dark energy.
