Abstract
The recently observed gravitational wave background is explained in terms of the quantum modification of the general relativity.
Keywords
Gravitational wave background, quantum modification of the general relativity, compressibility of the spacetime.
Introduction
Recently detected gravitational waves background (GWB) [1] remains a mystery, despite several suggested sources of it [1]. In this letter, GWB is naturally explained by the quantum modification of the general relativity (Qmoger), initiated in Ref. [2]. The essence of Qmoger is that the spacetime is not only curved (Einstein), but also compressible, which leads to new dynamics of matter/energy production/absorption by the quantum vacuum [2]. This effect was also supported by simple consideration [3], indicating that presence of the quantum vacuum is hardly consisted with exact conservation of energy, which is for classical general relativity ( see, for example, textbook [4]) . Developments and applications of Qmoger are in good quantitative agreement with cosmic data, including the accelerated expansion of the universe and recently observed early galaxies, without fitting parameters [5-10].
GWB in Qmoger
It is reasonable to expect, that feeding the universe, connected in Qmoger with compressibility of the spacetime, should create gravitational waves, not unlike waves on a lake in a rainy day. Indeed, in Qmoger, in the weak-field limit, we have two types of plane gravitational waves (see equations (18) and (19) in [5]). One is classical waves, connected with spacetime curvature, with ω/kc=±1, where ω,k,c are frequency, wave number and speed of light correspondingly. Another type of waves, connected to spacetime compressibility, are unstable in the weak-field limit with imaginary ω. It seems natural, that this second type of waves in Qmoger creates the observed stochastic GWB permeating the universe.
Conclusion
Gravitational wave background is natural in the quantum modification of the general relativity and connected to compressibility of the spacetime. In future, it will be interesting to consider these special gravitational waves in a nonlinear approximation for a more detailed comparison with observations of GWB and other phenomena, which could be related to compressibility of the spacetime. Particularly, on the list are recently observed minute-duration optical flares in "Tasmanian devil"[11], as well as some UFO [12].
