Siwanoy is correct... we could not run the Saturn float experiment even if we had a tub that big. But this is just a way to think about the density of Saturn, and to do so we need to let go of logic. If we 'turn off' gravity in our minds, and wrap Saturn in plastic wrap, the experiment works. But I do like the way Siwanoy thinks, and he is right on the money.

Yes... if you put Saturn in a big bath tub it would float... but it would leave one heck of a ring! I'm hear all week folks... tip your waiters...

Thanks Glen... How I did it is a long story... the short answer is make a lot of mistakes and learn from them (grin).

Me too... Even with the probes we sent to Mars, it is still a place of mystery.
Thanks,

Yes and Yes... the Moon was closer in the past (billions of years ago) and looked bigger then... AND the Moon is still moving away from the Earth. Due to friction from both land and sea tides, Earth's rotational energy is beging transfered to the Moon. This is slowing down the Earth's rotation (our days are getting VERY slightly longer) and that same tidal engery 'pushes' to moon farhter away.
Who knows... In a few billion years there may be enough time in the day to get everything done!
