Or why anybody with the Godlike technology to make it happen would even bother.

You ask God - plain and simple...

Hahaha, much as I hate to defend Will, that's a bit harsh - one was a bit of a drama queen with a big butt (IMO), but I certainly don't recall any 'munters'?

It was harsh, or rather, it would have been if it wasn't directed at Will!

At some point in the distant future (40 Bil years, I think) the moon with be "tethered" to single point over the earth. The earth's rotational speed and the moon's orbital speed will be identical at around 45 days. There will be no more tides.

Its the Gravitational Pull of the Moon on the Earth that creates the Tides.

Have you not seen "Bruce Almighty" .

If it was possible to remove the Moon from the Earth's Orbit (maybe some Huge Alien Mother-ship could Tractor beam it away from the Earth), Eventually the Tides would Cease, after several weeks or Months, because of the Lack of this Gravitational pull on the Earth.

When the Moon is really close to the Earth, which has happened on occasions where Tidal Waves have been created (shifting of Teutonic plates under the Oceans etc), The Indonesia
Tidal Wave for one Instance, the Earth is actually stretched by the Moon's Gravitational pull and actually appears more Ellipsoid than Circular.

I guess you knew all this already though, cos your such a Smart alec!

Well, the part you're criticising was correct - if the Earth's rotation and the Moon's orbital period were the same, there'd be no (Lunar) tides - there would still be the slight Solar tide due to the Sun's gravitational field.

You could have, to be picky, questioned his 45 day day, when he should have said 1080 hour day

Note, I have no comment on the situation he describes except I was of the understanding that, unless dome other force is applied to the Moon, it's orbit will continue to increase until it's lost to Earth - unless something happens beforehand...
Something to do with the Lagrange Points, perhaps?

Idiot.

Typographical error. I meant 45 day day. Editing now. I did a quick search and this number seems to vary between 44 and 55 days, so take it as you will. Note, I have no comment on the situation he describes except I was of the understanding that, unless dome other force is applied to the Moon, it's orbit will continue to increase until it's lost to Earth - unless something happens beforehand...

The average distance between the moon and the earth is increasing and the rotation of the earth is slowing. All the energy from tides is stored the difference between the earth's rotation and the moon's orbit. Once equilibrium is reached, the moon's orbit and the earth's rotation will be in unison. The same face of the moon will always face the same face of the earth. Parts of the earth will never see the moon and other parts will always see it. Lunar tides (as we know them) will no longer exist; the face of the earth directed toward the moon will just have deeper water.

This means, that in a nutshell, the moon is leeching momentum from the earth. The earth's rotation is slowing and the moon's orbit is speeding up. I suppose it is symbiotic, but I am a bit pissed at the moon for stealing energy from the earth.

Currently, a day is ~24 hours and a lunar orbit is ~29 days. The moon will rob enough angular momentum from the earth that it will increase its orbital speed to something in the hours and reduce the rotational speed of the earth to a common period (something in the range of 44-54 current days).

Down with the moon!

Thanks for the linc, Will, never heard of that before - all other scenarios I've read had the Moon just going further and further out. [thumbup]
I'll have a more thorough read tomorrow.

We did you think the energy to do that came from?

As with most others, it would seem, I never considered the transfer of angular momentum between the two bodies and the potential stabilising affect on orbits.
Not something I would normally take an interest in now - was mad keen as a kid with the Space race betrween the USA and the USSR.
