    Default Lunar Gravity



    I'm not exactly sure how much "common knowledge" this is, but I have herd that Lunar gravity has a major effect of the waters controlling the tides of the ocean. I have also herd that the human body is made up of 90ish % water. Do you any of you know anything more of this? I mean, I have seen much new aged research about theories that have been recently proven true about space but to my knowledge thats all the more complicated topics. Is this just television influence or is gravity this flexible?

    You are correct, the tides are caused by the gravitational effects of the moon, and the sun.

    Intresting, I never really thought of it to be more then speculation considering I saw it on dawsons creek. Is there a difference between when the gravity is most powerfull between the two? Sorta like how a full moon would have the most. What about the the sun, the suns always full.

    Tides are very complex. In theory, they are higher when the sun and moon are in the sky at the same time, (new moon) but are affected by the configuration of the shoreline, and underwater features. There is also a large componant of lag.

    Here are tidal graphs covering one week supplied by the Canadian Government for two locations; my home in Squamish B.C. and the head of the Bay of Fundy, which has the highest tides in the world.

    When you go to the sites, the data comes up in table form, but if you go to the left side, click the presentation drop-down, and pick graphic, then query, you will see graphs.

    Squamish, B.C.

    Bay of Fundy

    Interestingly enough, the volume of water that enters and leaves the Bay of Fundy twice a day (4 times) is greater than the volume of all the rivers in the world combined.
