Space-time curvature due to quantum vacuum fluctuations: An alternative to dark energy?

الأصل · EN

It is pointed out that quantum vacuum fluctuations may give rise to a curvature of space-time equivalent to the curvature currently attributed to dark energy. A simple calculation is made, which suggests that the value of the dark energy density is roughly given by the product of Newton constant time the quantity m⁶ c⁴ h-4, m being a typical mass of elementary particles. The estimate is compatible with observations.
