# Damhsa Theory: Can gravitational waves really affect the long term climatic evolution of Earth?

As a glaciologist I'm often involved in topics related to the long-term climatic evolution of Earth, and to the factors that can trigger or end ice ages.

Recently, I came across the paper "Applying Relativity to Earth Climate Data, The Damhsa Theory, Signs of the Inflationary Universe" presented in the SORCE Science meeting 2008 claiming that gravitational waves might have played an important role in the long-term evolution of Earth's climate.

However, I don't have the knowledge to assess the validity of those claims and the real significance, if any, of such effects. Could cosmic gravitational waves really have a significant impact on Earth's climate?

• It's like saying, what if the wind causes continental drift. – Mitchell Porter Mar 20 '18 at 20:53
• Glancing at the paper you link to what seems to be missing are solid numbers and their estimation by theory. There's a lot of talk about cycles and what amounts to coincidence, but not about the energy involved or the relative magnitude of effects. I would not really describe this as a theory, but more as loose idea without a firm basis. – StephenG Mar 20 '18 at 20:54
• It's also worth noting that, depending on the conference, they might not do any more than the bare minimum of vetting for the presenters (especially if the conference is big - there are always a few crackpots at APS meetings), so something being presented at a conference is not a very good barometer for its trustworthiness. Instead, look for this work to appear in peer-reviewed publications. – probably_someone Mar 20 '18 at 21:25
• @MitchellPorter: I would say that is substantially more likely. – Lightness Races in Orbit Mar 21 '18 at 1:06

• Wow, that is a bad paper. Not a single quantitative argument, just that "it could be true". The typical amplitude of gravitational waves is around $10^{-20}$; the amplitude of tides from the moon is $10^{-7}$ (give or take a few orders of magnitude) - we should expect vastly greater effects on climate from lunar influences. – Anders Sandberg Mar 20 '18 at 21:36
