Abstract
We investigate the quantum vacuum and find that the fluctuations can lead to the inhomogeneous quantum vacuum. We find that the vacuum fluctuations can significantly influence the cosmological inhomogeneity, which is different from what was previously expected. By introducing the modified Green’s function, we reach a new inflationary scenario which can explain why the Universe is still expanding without slowing down. We also calculate the tunneling amplitude of the Universe based on the inhomogeneous vacuum. We find that the inhomogeneity can lead to the penetration of the Universe over the potential barrier faster than previously thought.

A New Inflationary Universe Scenario with Inhomogeneous Quantum VacuumWe investigate the quantum vacuum and find that the fluctuations can lead to the inhomogeneous quantum vacuum
Gravity governs the evolution of the Universe
We analyzed the inhomogeneous vacuum in the Universe and come up with a new method for introducing the inhomogeneity by modifying Green’s function
