Extra Attraction Generated by Spacetime Fluctuations
Qingdi Wang
We show that, due to the nonlinear nature of gravity, fluctuations in spacetime curvature generate additional gravitational attraction. This fluctuation-induced extra attraction wa…
Comment on "Hiding the Cosmological Constant"
Qingdi Wang, William G. Unruh
We comment on S. Carlip's recent Letter "Hiding the Cosmological Constant" [Phys. Rev. Lett. 123, 131302].
How the cosmological constant is hidden by Planck scale curvature fluctuations
Qingdi Wang, William G. Unruh
It is argued in a recent letter Phys. Rev. Lett. 123, 131302(2019) that the effect of a large cosmological constant can be naturally hidden in Planck scale curvature fluctuations.…
Reformulation of the Cosmological Constant Problem
Qingdi Wang
The standard formulation of the cosmological constant problem is based on one critical assumption---the spacetime is homogeneous and isotropic, which is true only on cosmological s…
Vacuum fluctuation, micro-cyclic "universes" and the cosmological constant problem
Qingdi Wang, William G. Unruh
We point out that the standard formulation of the cosmological constant problem itself is problematic since it is trying to apply the very large scale homogeneous cosmological mode…
Can the fluctuations of the quantum vacuum solve the cosmological constant problem?
Samuel S. Cree, Tamara M. Davis, Timothy C. Ralph +3
The cosmological constant problem arises because the magnitude of vacuum energy density predicted by quantum mechanics is about 120 orders of magnitude larger than the value implie…
How the huge energy of quantum vacuum gravitates to drive the slow accelerating expansion of the Universe
Qingdi Wang, Zhen Zhu, William G. Unruh
We investigate the gravitational property of the quantum vacuum by treating its large energy density predicted by quantum field theory seriously and assuming that it does gravitate…
Mirror moving in quantum vacuum of a massive scalar field
Qingdi Wang, William G. Unruh
We present a mirror model moving in the quantum vacuum of a massive scalar field and study its motion under infinitely fluctuating quantum vacuum stress. The model is similar to th…
Motion of a mirror under infinitely fluctuating quantum vacuum stress
Qingdi Wang, William G. Unruh
The actual value of the quantum vacuum energy density is generally regarded as irrelevant in non-gravitational physics. However, this paper gives a non-gravitational system where t…
