The oceans would have been pushed to the poles and the overall shape of the earth changed from a sphere to a fat pancake. ...</strong>
Except for one thing: the spin-down rate is not a constant -- we are now in a period of relatively rapid spindown, because of some tide-excited resonances in the ocean basins -- the tides make parts of the oceans slosh at their "natural" frequencies.

Furthermore, there is an upper limit on the Earth's rotation rate that is determined by the combined angular momentum of the Earth-Moon system -- the Moon's orbital rotation has about 3 times as much angular momentum as the Earth's rotation. Which means that if all that angular momentum was in the Earth when it formed, it would have a period of about 6 hours.

However, it will be interesting to see how well "xBobTheAlienx" understands angular momentum and resonant frequencies.

xBob The Alienx:
Ya know, there are like 8 of you and 1 of me and its getting really tiring arguing with all of you at the same time.

Cry me a river. What did you expect?

Why in the world do you keep giving me links to 3-page long essays in every one of your posts!? i cant read that much on 8 year computer screen it hurts my eyes!

Cry me a river. You can always print them out or buy a bigger monitor.

Why do many cultures have legends of a worldwide flood?
Why do so many cultures have deity myths?
xBob the Alienx:
Maybe because its true?

And that all the deities of the various pantheons are 100% real beings. Yes, the deities of Mt. Olympus, those of Valhalla, etc. are all 100% real beings.

So when are you going to make offerings to these deities, O BtA?

I have an idea: lets all talk about 1 subject at the same time. You all go ahead and pick one.

After you.

So have you won anyone over? That you know of that is. Has anyone said "Oh my! Your explaination of change in earth's rotation made me rethink this whole creationism thing!"

I don't know. Can the dedicated amateur detect position shifts of less then 2 arc-seconds ?

I just wanted to stress that GR is tested during solar eclipses, not SR.

Have a care, O Christian! The prophtsized return of Great Quetzacoatl is immenent!

xBob, I'm sorry, but here we don't often do one-liners. Would you expect us to explain the science of Paleontology in a mere sentence or two?

To properly understand any subject, you must study all of it, not just the parts that are appealing and agreeable. Therefore we offer you most if not all of what we have. And we can dig up more, if required.

Now, no one expects you to absorb it all in an instant and no one is asking you to believe it if you do. All we ask of you is to review it with an open mind. However long it might take, we'll wait for your comments and/or questions.

I'm sorry if you feel ganged-up on, because indeed, that's exactly what's happening if you look at this discusion from a school-yard perspective. But if you review these posts, you will find that for the most part, each of us has added a little more info. We have no desire to bully you. All we want to do is put forth doumented information of the sort that fits your queries.

And believe me, bro, That info is accurate to current scientific thought. Here, it's got to be. If I were to tout Piltdown Man as a genuine, human fossil ancestor, these good folks would land on me a LOT harder than on you.

So. Read the links that I and the others have provided. They're well written, and in layman's terms so that even an old, iggnerent red-neck like myself can easily understand them.

Looking forward to your comments, yea or nay.

No; so why are you following this thread?

Continuing further out on this frayed piece of thread:

Yeah, they sure can. At least, the dedicated amateurs with no kids in college can. There are amateurs doing astrometry on asteroids to accuracies of maybe 0.1 arcsec - it is perfectly astounding what can be accomplished with a computer and a CCD camera.

Have your comments convinced anybody to stop participating in the discussion with xBTAx? If not, why are you still making them?

I hope not. But I was just thinking that the way you are going about it is just playing right into their hands. If anybody thinks they have a corner on the truth it’s got to be a Fundamentalist. Since this is supposed to be a forum of scientifically minded people and since there does seem to be a steady stream of willing test subjects, perhaps a more experimental approach would be more successful?

I think I'd have trouble getting that past our university's ethical committee - 'all subjects have given informed consent' etc.
