Thread: Water

Thats really cool. Thanks!

Ooooooh! Thanks, that was fascinating. Thats sort of what I was saying......okay, just a teenie tiny little spec of it was sort of what I was trying to express, atleast.
But thankyou very much.

The moon actually stabilizes earth's wobble. It's kind of like 2 people dosey-doeing (or however you spell it) their partner. If one let's go they will both fall over. Without the moon, the earth would go through extremely violent climate changes. It's actually very plausible to say that without the moon, life might not even exist on earth. Atleast not life as we know it. So to answer your question, sure, the moon does effect us.

In addition, I wanted to say that a full moon has no different effect on earth than a half moon for example. The light the moon gives off is just the moons position in relation to the sun and earth. Its gravitational pull does not change at all.

Hmm... why would the Earth wobble without the moon?

Because SpecialInterests doesn't understand physics.

EDIT: Oddly enough, the Earth does wobble, but it's small and has nothing to do with the moon one way or the other. It's just a result of conservation of angular momentum.

The force of graivty increases when moon is at perigee, though...

And yeah, why would the earth wobble without the moon...?

The earth spins because of the law of conservation of angular momentum and it was thrown off of the sun when it was forming. It does not wobble.

My viewpoint:
Let's take someone weighing 150 pounds. Approximately 70% water would be... 105 pounds of water? I have heard water as weighing 8.34 pounds per gallon, so using that number:

105 pounds / 8.34 = approximately 12.59 gallons.

Can we observe tides in swimming pools? Did the sports analysts watching the Beijing Olympics note the tidal phase when calculating the odds of an athlete breaking a swimming record?

Yes, it is unique. Just like all the other substances.

I'm not sure what you mean by weightless environment.

The tidal force actually effects both sides of the planet. This is why high tide is both at noon and midnight. What happens is, the closest 3rd or so to the moon is pulled slightly more outwards than the majority of the planet, but the back 3rd is pulled slightly less than the majority of the planet which amounts to it bowing out in the opposite direction.

The tidal force is only perceivable across large distances, like hundreds of kilometers.

My point exactly.

Oh, I misunderstood.

...umm...apparently I did'nt pay enough attention in 6th grade science class.
Wish it was one of my better subjects though. Then it would be easier to follow everyone's scientific explanations.
I feel really stupid right now...
Grrr!
What did I get myself into?
Sometimes I hate my questions.
Don't ask.
Anyway!
Thanks for the...very smart replys.

Hmmm - Are you willing to debate that the earth does not wobble? Here is my wager - everything I fucking own.

And @ Drewmandan - That's a bold statement to say that I simply don't understand physics bud. The moon IN FACT, by its gravitational force on earth, helps prevent dramatic movements of the poles that would fuel climate swings that some scientists figure might have doomed any chance for life to form, let alone evolve.

The earth does not wobble on its axis as it revolves around the sun.

When can I collect your belongings?

I didn't wager anything, first. And second, okay. The earth is pulled into a sort of minute wobble because of the moon.

Lewl. fine. Just to add, the earth doesn't wobble BECAUSE of the moon.

It said in the article that this extremely, mind-bogglingly minute wobble is the result of the tidal forces.

What if the moon didn't exist?

We wouldn't have been here.

How do you figure that?

If the moon weren't here, the only certain thing is that we wouldn't have tides. The oceans would be steady.

If evolution is true and we really came out of the ocean, we would have had a much harder time.

Discovery Channel did a documentary about what would the Earth be like were there no moon. Here's a blurb:

"What would life on earth be like without the moon? Well, chances are, there wouldn't be any life on earth without the moon. Life – if it had started at all – would still be in the earliest stages of evolution.

Scientists use the latest computer simulations to show how an ancient rogue planet – Orpheus – collided with the earth millions of years ago, producing a sizable chunk of debris that eventually became our moon. If that collision had never occurred, we would live in a very different place. Imagine a moon-less weather report – blizzards over the Sahara, flood waters swallowing the Pyramids, 90-degree temperatures in Antarctica. As the earth wobbles on its axis – unsecured by the moon's gravitational pull – the polar caps would grow and recede at frightening rates. And without the moon, our planet would spin much faster – meaning four-hour days and searing temperature

Imagine how dark the world would be at night without a moon...

One last effect worth noting is that the precession of the equinoxes, a 26,000 year process that shifts the earth's rotational axis in space and causes the stars that are overhead at night during a particular season to change gradually, is driven by the moon's gravity and would disappear if the moon were to disappear.

Overall I don't think a world without the moon would turn out any good for us.

^^That thing about the Earth wobbling without the moon is complete bullshit.
