Comment on "how the huge energy of quantum vacuum gravitates to drive the slow accelerating expansion of the Universe" [PDF]
, 2017 In a recent paper [Q. Wang, Z. Zhu, and W. G. Unruh, Phys. Rev. D 95, 103504 (2017)PRVDAQ2470-001010.1103/PhysRevD.95.103504] it was argued that, due to the fluctuations around its mean value, vacuum energy gravitates differently from what was previously
