    What do you base this on?

    In relation to tidal activity: Look at the difference in size of the earth compared to the moon and read what it says about tides. Does it seem odd that a small object so far away can have such a centrifugal effect?

    http://csep10.phys.utk.edu/astr161/lect/time/tides.html

    Is a relationship the result of wanting to see some relationship and merely coincidental?

    Why cant the earth by nature of its own movement create tides? unaided and completely self contained.

    Look at it as a basketball and a tennis ball. what possible effect can the tennis ball have on this much larger object and from so far away?

    By the same token: Multiply the moon by three and distribute the result equidistantly around the earth.

    What effect will this have? This is a secondary query with the post #41 being the primary query.

    the moon has not only have influence on our oceans but on he core of the earth itself. the moon keeps the earth in a stable rotation of his own ax.
    remove the moon and the earth becomes instable. it would move so wildly around his ax that the earths core would increase in speed and heat up.

    the gavitanional pull is the most effective force in the universe. why else would Saturn have a moon that is to hot to have life on it??? because saturns gravitanional pull effects the core of the moon heating it up.
    the sceer form of the moon changers with eath rotaton around Saturn.

    Luna has a gravitational pull that effects the earth tremendously.
    remember that the earth isn't standing right up. the ax is tilted. themoon keeps it this way. if you remove the moon. the ax would be flipping around like crazy.

    i must say i do believe that the sientists of nasa are a credible source don't ya think. Scientists stated that without the moon there is no life on earth except some adaptable species and man isn't one of them.

    Give up the leaf, Lord Vasago, learn how to spell, and stop spouting nonsense.

    The Moon does stabilize the Earth's rotation by countering torques from Jupiter. Suppose the Moon suddenly vanished. The immediate effect would be a 2/3 reduction in the tides, and nothing else. Would the Earth spin up? Nope. "move so wildly around his ax that the earths core would increase in speed and heat up"? Nope. Longer term (tens of thousands of years), we would see a change in the lunisolar precession. Big problems (Earth rotating like Venus) would take a much longer time (tens to hundreds of millions of years) to appear.

    -------------------------------------------------

    Agreed. However, while life might have had the opportunity to form, the Earth would not have retained life-supporting conditions for the extremely long time needed for complex life (and then intelligent life) to have formed.


    One way is with simulations. That is precisely the technique used in the references cited in post #27 to determine that the apparently anomalistic orientation of Venus is not so anomalistic after all. It is a natural consequence of interactions with Jupiter over a very long period of time.

    Venus has a surface temperature of over 460°C, hotter than Mercury, even though Venus only receives 1/4 of the Mercury's insolation. While a Venusian-style atmosphere on the Earth would not result in a 460°C surface temperature (Earth insolation is a bit over half of Venus'), all it would take to make Earth completely inhospitable to life as we know it is a surface temperature over 100°C.

    -------------------------------------------------

    Not odd at all. It's all in the math. The tides are very well explained by Newton's law of gravitation.

    I can point to 6 billion people that didn't win the lottery their third time. Please point to the other Earth-like planet that doesn't harbor life.

    One of us is batting 1.000 and the other is batting .0000001

    Venus and possibly Mars, and definitely both if you want to talk about Earth-like planets that don't harbor complex life.

    Yes, i believe in gravity.

    So far nothing concrete to support the moon having some kind of actual function. Not trying to re-invent the wheel here but...

    Stop with the religious/metaphysical junk, John99. The Moon doesn't have a purpose. That it exists certainly does result in a lot of consequences. Big difference.

    I have no religious affiliation and o don't know why you would say that. That is just not fair.

    I just thought of this awhile ago and if i can prove then that is exactly what i will do.

    lol
    John why do you think the moon orbits the Earth ?

    But that is a factor of the earths doing and not the other way around. I will be back later and plan on doing much more research and intense thinking.

    I admit i got a little upset by the other post because my observances are strictly based on science and I will rely solely on scientific methodology. And if it turns out i am wrong...so be it.

    Well, you are wrong.
    Does the apple fall to the Earth, or does the Earth fall to the apple ?

    Are you REALLY this dense, or are you just trolling now? You admit that a person who wins the lottery can only know whether or not winning the lottery is hard by checking to see how often other people win the lottery. Similarly, we can't know how likely life in unless we check other potentially life-supporting planets around other stars and see how many of them have life.

    If you still dont get it, I will assume that you are either a toll or simply too stupid to bother with.

    Maybe. I'm curious though if it is possible to slough off enough crust and atmosphere through, say, several smaller impacts over a million years or so - far enough apart that any ejecta that makes it into orbit has time to sufficiently dissipate so we don't see the formation of the moon, but the crust becomes thinned enough to support tectonics, and the atmosphere becomes thinned enough to support life.

    I was aware that people were looking into chaos in the solar system, but somehow I missed that it had progressed quite that far (i'm a chemist, not a planetary physicist, that's my excuse, and i'm sticking to it (; ).

    And yes, those references were intriguing.


    Yes, I understand that, however it was also my understanding that it wa sthe loss of the venusian oceans as the suns brightness increased 'early' in its evolution that did the venusian climate in (Gotta have water on the surface to recycle carbondioxide back into the mantle).

    I don't think the moon has anything to with Earth's perturbation.
    I do think that it has something to do with Earth's ovoid spherical shape.
    Perturbation is a one time event. The moon's gravitational influence is continuous.

    Not at all. It is not a small object and exerts quite a significant force on the earth

    Read my earlier post. Do you think it is merely coincidental that the tides can be predicted accurately only by including the effect of the moon? Do you think there is some other gravitational force that mimics the effect of the moon or something?!

    i don't know saquist. I just saw a docu on discovery the otherday and a nasa scientists explaned that the moons gravitational pull is the reason why humans can survive because it littely calms the planet down.
    I really don't know but i think these guys know what they are talking about.

    they also stated that the moon is mooving away from earth. and that slowly she will lose her effect on earth making it a violent planet again.
