Some people (Jews and some Christians) believe that God's name is so HOLY that it should NEVER be spelled out as respect to THE ALMIGHTY.
Thanks.
But only as comfortably convenient if on my account.
Blessings,
True enough . . . so far.
Since the atheists are trying to take God out of everything, I guess I am overly sensitive.
Please accept my apologies!!!
I Think of the earth as being a raisin in raisin bread as it is cooking. It's always in motion and the volcano is just excessive heat that got into the raisin and blew a hole in it. The raisin stays in place with a small void which will fill with ? (Internal). What it releases and moves is equalized on the surface of the earth until everything is in tandem again. Our earth is in a state of perpetual change as is the universe. It's this great balance that is awesome and GLOBAL WARMING is just a little piece of sh**.
Would you at least one person at DU was making that case? She was claiming that global warming had increased the depth of the ocean to the point that a tragedy like this was available, and global warming was all the fault of Bush.
I don't think I need to bother to debunk that.
"All the planet is vibrating," Enzo Boschi, head of Italy's National Geophysics Institute..."
Desperate for riveting articles that prove their relevance, the media is beginning it's tailspin descent into the level of journalism formerly reserved for bat-boy and UFO's. The next wave of articles will probably sound like those from 1950's 'B' sci-fi movies...
Not really. Time is maintained in two ways - atomic clocks and by measuring the rotation of the earth as compared to distant stars. Given that astronomers do this all the time, it's fairly easy to see when discrepancies pop up between the atomic time and the "stellar" time.
However, the "built in" error was removed not long ago and that was 100 feet so I'm not betting on the new location yet.
Thank you for correcting my spelling, too; because it is tough, for some reason, for me to hit all the keys, though I am pretty sure that the keyboard misses a beat in the Shift, I am fairly certain that otherwise, the problem is in my head.
No. The angular momentum of the earth can only be changed by either encountering an extra-terrestrial object that transfers angular momentum to us (for instance, by collision with a sizeable asteroid, particularly if the angle of collision is "glancing") or by ejecting some material from the earth and thereby carrying away some angular momentum.
However, the rotational speed of the earth, or the orientation of its axis of rotation, could be changed even if its angular momentum does not change, if there occurred a sufficiently radical redistribution of mass within the earth, including its crust.
You can prove this to yourself by getting one of those little half-pint cartons of milk and "flipping" it in the air. You will observe that the carton always ends up rotating at a speed that is considerably slower than you expect. This is because you are imparting spin to the carton, and the carton, in turn, imparts spin to the milk it contains, but this process takes place after the carton has left your hand.
It is also possible (though doubtful IMO because of the magnitudes involved) that some angular momentum the earth once had got "trapped" in the form of stored energy (by putting millions of cubic miles of rock located in earth's crust or mantle under stress) at some point in the distant past. If an earthquack were to "release" this stored angular momentum, it could change the earth's rotation.
But, as I said, it seems to me that for this to be measurable the earthquake would have to be truly biblical. Massive tidal waves in every ocean of the world, costal cities everywhere devastated, that sort of thing.
As big as this one was, it's energy release was small potatoes compared with a quake that could do that sort of thing.
What the Dr. Boschi said is that "the planet is vibrating." This could be the case with no change in angular momentum whatsoever.
(steely)
I tend to agree with this. That gaping hole had to refill with something from someplace....either behind it or from the side of it...you HAVE the idea.
A mouse scammering across the room changes the rotation of the earth, though not in any measurable way. This earthquake and resulting tsunami could not significantly change the angular momentum of the earth as a whole, however, if it redistributed the mass of the earth, it could change both the rotation rate and the rotational axis.
The canonical analogy is the ice skater who spins faster by drawing her arms in towards herself. The actual case is a little more complicated. Leaving out the astronomical effects of nutation and precession (which actually do involve long term predictable changes in the direction of the earth's rotation and hence changes in the earth's angular momentum) the earth's axis of rotation wobbles around its "mean" or conventional point. This wobble is not completely understood, but it is not much different than the expected results of "eulerian wobble". You see "eulerian wobble" every time you see a replay of a pass thrown by Jim Plunket - a not perfect spiral.
The effect is somewhat subtle, one second of arc corresponds to a displacement of about 30 meters on the surface of the earth. For a good discussion of matters effecting the earth's rotation start here
These astonomers are awesome. There's another I would like to hear from....Apache Point.
We need to reset our clocks to 8pm (EST). The date is now June 12 and please amend all maps and atlas' to show that the north pole is now located at Parma Ohio. Thanks
I thought it was a Pacific fault...
Look at "Earthquake Park" in Anchorage." A vast area of land that dropped 20 feet when their 9.2 hit in 1964.
Thanks. Your explanation helps.
