Is The Earth Changing Its Rotation?

Call me crazy, but I think Earth is going away from the sun mainly because the incidence of light is increasing. Once I saw a theory about the equilibrium of the celestial bodies, it states that it isn't maintained by their masses but by their emission of "light".
Maybe we should see if this is happening to other planets too, if there's some kind of correlation.

This could very well be true. I tend to think of the earth as a living organism, so it would stand to reason that it may would retreat from the sun as a method of self preservation.

Do we end up somewhere else? Would we be aware? Would it happen in seconds or days or months?

One of the perplexities of the earth's movement is that we are not aware of it. It seems that I read somewhere that the earth is traveling 19,000 miles per minute, yet, we are not aware of it. It was either 19,000 miles per minute, or per hour. I don't remember which.

Maybe I'm an idiot, but it seems like they may be related.

Well, the earth's magnetic field as been weakening for the last 100 years. Know one seems to have a real good grasp as to why. As far as the birds dying because of it, possibly. Migrational birds depend very much on the strength of the magnetic field. To be honest,Alien, it's not my area of expertise, so I can't really give you a qualified answer on it.

Apparently, this is something that the earth has been headed towards for quite some time. I suppose it didn't just suddenly occur.

It is a known fact that the rotation of the Earth is gradually slowing. For four and one half billion years, its entire life, it has been slowing down. As the Earth loses its kinetic energy due to all forms of friction acting on it (tides, galactic space dust, etc.) like any other flywheel, it will slow down. From time to time our timekeepers must adjust their super accurate atomic clocks to synchronize them with the Earth's slowing rotation whose day/night cycles we base our lives on.

Scientists estimate that the Earth's rotation is slowing at the rate of 2.2 seconds every 100,000 years. The time it takes the Earth to complete one rotation increases 2.2 seconds every 100,000 years. This is a very conservative figure considering the number of adjustments our timekeepers have been forced to make in recent years. If we trace this phenomenon back in time, whatever the correct figure is, at one point in time it may have taken the Earth 12 hours to complete one rotation, (depending on its initial speed of rotation when it was created.) At that time the Earth was spinning at twice the speed it is traveling at the present time.

The constant gravitational force and the weakening angular momentum caused by the slowing of the Earth's rotation has had a profound effect on the Earth's geophysical activity throughout the ages. Throughout the life of the Earth there has been a continual adjusting of the Earth's shape as the ratio of the strengths of angular momentum and gravity has changed. Gravity is a centripetal force, it exerts its tremendous force inward, toward the center of gravity, always trying to form the Earth into a perfect sphere.

Any effect?

A huge impact. There's been modeling studies done showing that the moon is partly responsible for life on Earth (stranding things in tidal pools where they had to adapt or die, for example.)

My math isn't up to doing the multibody calculations to be able to tell what changes would happen to the rotation pattern if the Earth didn't have a moon (it's very advanced calculus/algebra.) However, I can say that without the moon the Earth wouldn't wobble in its orbit.

Byrd, do you you think the earth would move at all without the moon? I mean, rotation and wobble is about the only movement the earth makes. Without a wobble I don't see it rotating either.

No, it's different causes.

Magnetic field weakening has to do with the Earth's core.

Bird dieoffs are from a number of causes -- among them, bird flu. Migratory birds die from different things than non-migratory birds do. And there are deliberate attempts to kill birds on large scale in some urban areas (starlings and grackles and pigeons... I've seen municipalities put out poison bait for grackles and not care that other birds get into it.)

I'm pretty sure that magnetic weakening didn't cause people to put out poisoned bait.

Oh yes. We have other planets in the solar system that move (and rotate) without moons. Mercury... Venus... Mars (the two 'moons' are little more than small asteroids captured by the planet). Rotation came from the initial accretion disk (the stuff that the planets were made from was orbiting around the sun. As it lumped together to form planets, the spin remained... rotation was caused by impact of larger fragments.

I didn't realize this was occurring. I mean, I know some people don't like a bunch of birds around but I wasn't aware that there were municipalities trying to kill them off.

Makes sense. I took earth science in college but it dealt more with geological changes than it did with earth's rotation and such. Thanks for the information.

It seems that the rotation of th eearth is pretty important.

Solar Rotation Effects on the Thermospheres of Mars and Earth
Jeffrey M. Forbes,1* Sean Bruinsma,2 Frank G. Lemoine3
The responses of Earth's and Mars' thermospheres to the quasi-periodic (27-day) variation of solar flux due to solar rotation were measured contemporaneously, revealing that this response is twice as large for Earth as for Mars. Per typical 20-unit change in 10.7-centimeter radio flux (used as a proxy for extreme ultraviolet flux) reaching each planet, we found temperature changes of 42.0 ± 8.0 kelvin and 19.2 ± 3.6 kelvin for Earth and Mars, respectively. Existing data for Venus indicate values of 3.6 ± 0.6 kelvin. Our observational result constrains comparative planetary thermosphere simulations and may help resolve existing uncertainties in thermal balance processes, particularly CO2 cooling.

What it means

Obviously, a movement toward the sun would increase the temperature and a move away from the sun would decrease the temperature. I suppose that is common sensical. However, there are also other ramifications of this anomaly.

I don't know if the earth's wobble has an effect on the velocity of the earth's rotation... but the days were getting longer...

If anybody wants to find out more about this wobble... try searching "Chandler's wobble". I read about it and was intrigued.

An interesting topic indeed.

I saw a program on Discovery (Can´t rember the title) where they talked about the earths magnetic field shifting & as someone already pointed out here,it happens very fast.If my memory serves me right they talked about 7-8 days.They messured this change in some very old lava stream they found somewhere.(Checking the same stream but different parts of it)So when it happens it happens very fast.They didn´t mention a tipping of the earth itself.But that the earths magnetic field would be banans for some time.In some places very strong on others very,very weak.I rember this part because some guy did run a computer simulation of it.

A polar shift would more than likely disrupt a lot of electronics with fluctuations in the normal and mostly stable magnetic field. We would more than likely be mostly unaffected unless if affects us mentally or creates confusion in our senses but if that were the case then walking near power lines would also affect us.
As for the wobble, oscillations and drift. We are being tugged on by Venus, Mars, Jupiter and somewhat Saturn. The effects depend on conjunctions and other alignments. You might say that they project ripples in the suns magnetosphere. The moon while noticeably affecting tides drives the oceans and plays a part in ocean currents. This has an effect on weather patterns in a way that the weather may not have supported life without it. That may be a hypothesis but it sure fits all the models.

For the outward creep?, If you consider the tonnage of mass converted to energy and emitted as an array of particles blasting outward, then out old friend Sol is loosing weight over time and thus would have a shrinking gravity well. We will slowly drift away. I don't know about you all but I'm not waiting around for that one.

Sorry for this brief post. I wasn't sure if this would post in the right spot, so I'm just testing! :-)

Hi all-

I read all the previous posts in this thread and didn't see that anyone else had the following info, although everyone is making incredibly intelligent guesses!

I just found this source a couple weeks ago and I'm really freaked out by it, but you can inform yourself.

If any of the following info sounds legit to you, please check out the info for yourself - don't take ANYONE's word for it because there is a tremendous cover-up in place.

"WHY are there all these irregularities to the weather, the earth's rotation, etc.?"

There is a planet with a VERY elliptical orbit, larger than the earth, that has entered our inner solar system. It has an orbit that passes approx every 3,650 years. Since it is near the sun, it is hard to see, but there have been many opportunities AND PHOTOS taken, and if you punch enough questions into Google, you should find this. (didn't know if I could post a link??) You could search Nancy Lieder. Please READ the info on her site before dismissing it.

By the way, you won't see this info on NASA's site, or anywhere else. Avoiding mass panic comes to mind...

- A polar shift IS pending quite soon. The magnetic pull of this planet, as it passes, will completely rearrange our poles.
- The poles WILL shift to entirely new locations. This rearranges the entire planet's surface, but it IS possible to survive this.
- No dates are known, but signs are our only clues
- The sun rising in the west WILL be a sign... and then possibly too late to do anything about it, so please inform yourself now.

As far as the birds dying off, its due to plate shifting that is releasing trapped methane gas from rotting vegetation between rock layers. These releases have also set off gas-detection alarms on ships at sea, but no fuel leaks were found. That's why everyone is clueless about these weird die-offs, and strange alarms.

Shifting earth = sink holes, of which many have been showing up lately

Anyone following the earthquakes? Increasing, increasing... and being underreported.

Everything is changing, and always has (including climate). the universe isn´t some thing that stays the way it is forever.

Humans have been here for a minute insignificant dot of time and its amazing that some people arrogantly think that things will stay the same as they have been in this time fame.

WRONG!!

don't worry guys, we'll be toasted or frozen to death in only a couple million years from here !

Just to be clear, it seems a few people are confusing a "POLAR" shift with a "Geomagnetic POLE Shift". The 2 are not interchangeable.
A POLAR shift has implications VASTLY more destructive than a geomagnetic pole shift may from the onset. (Think entire oceans tilting for example, like the difference of holding a glass full of water straight up versus tilting it on an angle--and in THAT there are axial POLAR shifts versus Equatorial POLAR shifts).

Our old friend Sol is gaseous, and it's highly doubtful that she's "losing weight"

If that is indeed the case, I doubt if humans will still be here to see it. We will have long since been annhilated. I hope that makes you rest well.
