Dark energy gravitational wave observations and ice age periodicity

Abstract

Dark Energy is the dominant component of the energy density of the Universe. However, it is also very elusive since its interaction with the rest of the Universe is primarily gravitational. Since Dark Energy is a low energy phenomenon from the perspective of particle physics and field theory, a fundamental approach based on fields in curved space is sufficient to understand the current dynamics of Dark Energy. The key issue is to understand the gravitational dynamics of Dark Energy and its observational consequences. However, finding the observational consequences of Dark Energy dynamics has been a very challenging task. For something which is the dominant component of the energy density of the Universe, Dark Energy appears to be very distant and reclusive. Here we show that the Dark Energy dynamics results in the production of gravitational waves which produce the ellipticity variation in earths orbit that results in the periodicity of the Ice Ages observed and documented by geologists and climatologists. Previously, no observational signature of gravitational waves produced by Dark Energy dynamics has been reported. Further, no interpretation of the ellipticity variation of the earths orbit due to gravitational waves or the linking of such gravitational waves to the Ice Age periodicity has been reported previously. We hope that the current work will lead to some fresh insights and some more interesting work.

Background gravitational waves as signature of the accelerated cosmic expansion

“…Recently, a body of works has devoted interest in the dynamics of dark energy by the emission of gravitational waves [38,39]. This line of investigation is important since it can contribute to the innovation of studies involving dark energy, its cosmological role, phase of inflation and the relationship with the cosmological constant.…”

Gravitational waves: A review on the future astronomy

“…This order of time period of this signal is very large in comparison to the human lifetime. With the help of a more sensitive detector, the study of such sensitive GW signals will be possible, and it may create more understanding about the dark energy concept (Singh, 2020) [37] .…”

Gravitational waves with dark energy

“…This effect is contrary to the previous cases where DE itself is the source of gravitational waves. Therefore, interactions of DE fields with the rest of the universe extract the gravitational wave signal with an amplitude ∼ 10 −2 , which corresponds to a frequency of ∼ 10 −13 Hz [41,42]. The present article aims to study the effect of DE on gravitational waves based on the other mentioned models and compare the obtained results.…”
