I don't have the scientific knowledge to assess all this. I'm not even sure how to understand properly the questions Jeanne Rousseau asks saying newtonian physics can't answer. What I hear however are competent people observing small variation in the properties of water and living systems that seems to be related to cosmic phenomenon, including moon phases. Variations we can also find in the atmosphere/ionosphere with more recent measurements of their ionic polarities. Adding to that are all the new discoveries that link weather phenomenon to electromagnetic influences from the sun, with water significantly influencing the electromagnetic properties of the atmosphere. Finally more people question the true molecular structure of water, as H2O seems to be a crude simplification over a dynamic mixture of isotopes and ions.
Overall the tidal theory is not a done deal, we only have approximate models, and this topic can be discussed for years to come. That's probably why she was told the tides is a phenomenon that is beyond us.
