Careful measurements made by bouncing lasers off mirrors placed on the lunar surface have revealed that the moon is moving away from us at about 1cm per year.

Why is the moon migrating further away from Earth, and will it ever "escape" entirely?

Hi Chris

I believe it will stop moving away once the earth stops rotating as its the energy it robs from the earth rotation through tidal action, slowly making our days longer which allows it to move away.

Basically i believe it robs energy from the earth through tidal action .The energy its robs is from the earths rotation and the energy it robs from the earth rotation puts energy into its angular momentum causing it to move slowly away from us

What is the mechanism of the energy transfer ?
Gravity ?

Yes. Gravity, causing the tides and slowing down the Earth's rotation. The angular momentum of the Earth-Moon system must remain the same. As the Earth's rotation slows its angular momentum drops. The moon's angular momentum rises by the same amount, which increases its speed, casuing it to move further away from the Earth.

 The moon is moving away from Earth
Due to the tidal forces of weight [gravity] and the tangential component [vortex force] two parts, vortex force to the moon is of increasing angular momentum away from the Earth, this process of angular momentum conservation, therefore slowing down the Earth's rotation cycle. In recent years, some countries in the world after scientists and technical workers in-depth observation and research, found that the moon is gradually away from us, and will be increasingly dark. The United States and France scientists use astronauts landing on the moon in 1969 when the United States placed in the mirror on the moon to measure the results showed that in 28years to the distance between the Earth and the moon increased 1 m, The United States and France the two scientists is the use of accurate time measurement to measurement, the distance between the change, This method of pulsed laser projection, and then to the mirror reflection back on the ground detector, a return of about 2.5 seconds, Constantly measuring return by the time the changes on the distance that can   change. Repeated measurements show that the earth and the moon because of the distance between the earth's surface tidal friction role annual increase of nearly 4 cm. Scientists believe the moon and under the influence of the Earth's gravitational tides produced, this tidal movement on the part of decentralized energy to the Earth's oceans, As a result of this energy - the loss of the campaign on the Moon system be affected, and this is moving away from the Earth's moon reasons. United States 2 geographers through Nautiloid Fossil study also found that the moon is moving away from Earth indeed. The two scientists observed several Nautilus existing fossil study found shellfish on the tree-ring wavy thread with the same performance, Thread at many points, though different width, but on every small wavy line growth in the 30 or so with the modern Lunar exactly the same as the number of days a month. Observed that the Nautilus, wavy lines of a long day, following a month long. Growth in this special two scientists to be greatly inspired, they observed the Nautilus ancient fossils surprised to find that the growth of every parrot the lines traced with the fossil's diminishing. And the age of the same line of Nautilus shell growth has to be fixed. Research shows that the modern Nautilus shell, the growth line is 30, the new generation of Oligocene Nautilus shell , the growth line is 26, Cretaceous Mesozoic is 22, 18 is Jurassic, Paleozoic Carboniferous is 15, Ordovician is nine, Concluded that 420 million years ago before the Ordovician, Paleozoic, and the moon around the Earth only nine days a week. Two geographers According to the Law of Universal Gravitation, such as physics theory, the moon and then calculated the distance between the Earth, Get a result, more than 400 million years ago, the Moon and the distance between the Earth is now only 43%. Scientists have also nearly 3000 to a record of pitting corrosion phenomenon on the calculation, of the findings fully consistent with the reasoning that the moon is gradually away from us.                             
using gravitational& vortex force  the formula to calculate the moon from Earth:
Cos а ≈ 1
Me = 6 × 10 ^ 24kg; month - the distance r = 38.4 × 10 ^ 7M
Mgh = mv^2 / 2 ①
V = at ②
Moon average week: v-= 1 / π ∫ vsin ω td ω t = 2v / π ③
Angular velocity difference: q = 29/30 = 1-1/30
V-= 2at / π; ω = 1 / T
a = KGM ω/ r ^ 2 ④
Mg = GMm / r ^ 2 ⑤
111Daily the moon away from us:  h = 2GK ^ 2Mq / π ^2 r ^ 2
= 2 × 6.67 × 10^-11 × 0.16 ×  6 × 10 ^ 24 × 29 / [38.4 × 10 ^ 7] ^ 2 × 3.14  ^ 2× 30
= 8.51 × 10 ^- 5m
From a year: 8.51 × 365 × 10 ^- 5 = 0.031m
This is close the measured value

The reason that tides / rotation transfer energy between Earth and Moon is that they are big enough and near enough to each other that they can't be treated as 'point masses'.
We tend to think of orbits as depending just on the masses and separations but that is an over simplification if you want to get accurate predictions. The 'centre of mass' is a very useful idea but doesn't tell the whole story.

Hasn't the moons mass been compromised by the various Apollo missions? Increasing the moons mass will cause it to shift into a different orbit, that is maybe what we are seeing.

The way that the distance is being measured is by bouncing a laser off some mirrors on the surface. The calculation is based on the time the light takes to make this trip, however, the lights speed is affected by the density of the atmosphere and this may not be constant. (They may be aware of this and brought this into the calculations though)

Just speculation but could it be down to the expansion of the universe.

If the moon is moving away from the earth then would not the same be happening with the earth around the sun? Is that why we have to add a second to time every so often?

In the scope of our local vicinity, the expansion of the universe is negligable.  By local vicinity I'm thinking in terms of as far away as the Andromeda galaxy, which is part of our local group, and which is actually moving towards us, or visa-versa perhaps, as it is considered to be more massive than the Milky Way.

The reason we need to add an extra second every now and then is because the orbit of the Earth around the Sun doesn't take exactly 365.25 days and actually varies by a tiny amount depending on the position of the other planets, so adding an extra day every four years isn't quite good enough, even allowing for the 400 and 100 year conditions.

vortex force Introduction of
  In the beginning of the last century, Astrophysicists face a problem, Mercury recently at the precession (Newton's theory deviation of: 43 angle seconds per century ), This is the quote the classics scholars can not explain, and it is not Newton's theory of classical mechanics adopted by a storm. Then only 37-year-old in 1916 Einstein published the《〈basis of general relativity〉》,Schwarzschild Metric German mathematician in the field equations of general relativity to the Mercury precession of the mystery,Mercury precession was therefore established the general theory of relativity early as the first major experiment. Later measured the Earth, Venus and other planets has also point precession of the general theory of relativity and the calculation of anastomosis with good results. Mercury precession and in the light deflection in the gravitational field, the gravitational redshift spectra of the three major criterion known as general relativity.
  In the beginning of the new century, have an astrophysicist at the problems facing the front ,This is NASA launched the "pioneers 10" "Galilean slightly," four spacecraft speed reduction. American scientists through 10 years of observation, found space for the role of a slowdown The effect is tiny - only about one part in 10bn of that due to the Earth's gravity acting on you right now - but it is definitely there. So some scientists questioned Newton's Law of Universal Gravitation, However, while some scientists believe that the best flight path is based on the parameters calculated, it is too early to doubt the basic law. We explore the long-term, in 2001, with Cavendish balance is measured not only by gravity to the component (that is, Newton's gravity), but also the existence of the tangential component, and that formula. To our planet, as an example, in addition to the original gravity (ie to the component), with the rotation of the earth, there are around in the vortex force of its (tangential component) the existence of ,The vortex force of (that is tangential component) and the Earth's rotation rate is proportional relationship.
  In the gravitational theory to elect representatives, it seems that non-Kepler, Newton and Einstein to my mind. It is worth noting that three representatives in the two agree that planets or stars in the rotation around a vortex. Kepler's idea of the same gravity as the car spoke, on the one hand to maintain the planets in their orbits can not run away (ie the components), on the other hand, with the sun's rotation around the sun forced planetary rotation (that is tangential component) . Einstein's general theory of relativity in there is a little-known forecast to be tested, the framework called gravitational drag [frame dragging]. When a planet or star rotation in space, it will drag space-time in its surrounding. This is very like the following example, when you filled with water in the bowl, one ball, and their rotation, the surface will be generated by the friction of water along the direction of rotation drag ball, the ball near the water in the rotation faster, the farther away from the ball, the friction of water drag effect will be weak. Newton's theory does not recognize the planet's rotation a scroll, so could not pass on Newton's theory of the "Mercury precession," this hurdle, a spacecraft can slow down this hurdle, Not only that, in many helpless astronomical phenomena, such as the angular momentum of the solar system, Venus reverse rotation problems…… . Practice is the sole criterion for testing theory, laboratory come to the conclusion also subject to the test of practice can rise to the theory.
  use of vortex & gravitational force formula, explain and calculate the following questions. vortex force of 12 major criterion [quantitative calculation, high school students can master]
1. Mercury precession 43 "per century. (Newton's theory of deviation values.)
 2. Venus precession 8.4 "± 4.8" per century. (Newton's theory of deviation values.)
3. Earth's precession 5.0 "± 1.2" per century. (Newton's theory of deviation values.)
4. "Pioneers 10" four spacecraft speed reduction. ( slowdown by the the acceleration : one part in 10 billion of gravity at Earth's surface )
5.the moon Away from the Earth (3 cm per year).
6. Cycle of the Earth's rotation slows down. (Per hundred years 0.00164 s] ,
7. Coriolis force whereabouts eastward.
 8. Around Mars Phobos campaign cycle to slow down the week 0.1 ms
9. Sun-synchronous orbit satellite orbital plane precession; altitude of 900 km polar orbit satellite orbital plane precession of the daily 1 degree. The orbital plane of the vertical scroll relatively static, the situation in order to prove Scroll of the accuracy of the vortex force and an excellent opportunity.
10. Oblate of the Earth , 5 × 10-5m/s2. On the Global Positioning System GPS satellite orbit produces nearly 10,000 meters every day the impact of this phenomenon of vortex theory can be used to explain and calculate. Satellite orbit calculation of the largest perturbation of the - non-perturbation of the ball, not the flat rate from the Earth, but the role of the vortex.
11. Solar wind acceleration: time to reach the Earth, usually in the jet speed of 450 kilometers per second around.
12. With near 20years explore the more than 300 people each repeated verification; used Cavendish torsion balance measured vortex force of existence, and that formula New gravitational formula in the 2001 :
 F = Fn + Ft
To the weight of Fn = GMm / r ^ 2 -
Tangential component [vortex force] Ft = kGMm ω Cos α / r ^ 2
K = 0.4 for one factor,the unit: sec/Band ;
 ω is the angular velocity rotating ball, the unit: Band / sec;   
α to the orbital inclination.

Mercury precession (Newton's theory deviation of: 43 angle seconds per century )
  1. Kepler's idea of the same gravity as the car spoke, on the one hand to maintain the planets in their orbits can not run away (ie the components), on the other hand, with the sun's rotation around the sun forced planetary rotation (that is tangential component) . I use Cavendish torsion balance has been measured rotating the ball around the vortex of existence, and that formula. Use of vortex force & Newton's gravitational the new formula, explain and calculate a lot of problems. The prediction of general relativity - inertial system drag (frame dragging) should be the vortex force.
  2. By Kepler's idea of the sun's magnetic lines of a similar thing, we may wish to call it gravity line, The sun's rotation gravity-driven rotary, scroll to the transfer of the planets, scroll to the transfer of planets. The planets corner speed is less than the sun's rotation velocity resulting precession. Moon, too, was angular momentum away from Earth. If the satellite is the corner speed of the earth's rotation velocity, the satellite is not cutting gravity line from the vortex of . Geostationary satellite is the case. If the satellite is greater than the corner of the earth's rotation velocity speed, scroll of satellite impede movement, the angular momentum to reduce satellite orbit decay decline , thousands of man-made celestial bodies are so, the Mars satellite Phobos as well.
  3. No rotation of the sun's or rotation corner velocity is less than the rotation corner speed of Mercury, Mercury can not be precession, moving instead to retire. So with the solution of Schwarzschild Mercury precession [Newton's theory of deviation], I can not agree. If the inertial system drag of general theory of relativity to explain the Mercury precession, I think But good. Einstein was the problem with Mercury moving into the capture of the stronghold of Newton, is now a directional errors.
  4. Solve the Mercury precession [Newton's theory of deviation] There are many ways to the present, there is more than 10 domestic, but with the added vortex of gravitational theory to explain primary and secondary school students will be able to understand [qualitative analysis] and high school students can quantitative analysis.
  5. Reflection: no force act, no angular momentum transfer, no energy conversion, the Mercury can precession [Newton's theory of deviation]??

Hahah, here's my noobish but "I think it shouldn't be left out" answer ->

sun is a larger celestial body than moon, so it exerts a larger gravitational pull than earth, hence moon moves away! whee!

BUT, this pull only works when the moon is closer to the sun! on the opposite side, the earth blocks the moon! the moon is further, thus less pull from the sun! the sun pulls the moon back towards the earth! so I don't think it'll escape!

Ophiolite's said it all. Why not accept that this is a perfectly good explanation? And the numbers fit the facts.
Invent a New Theory for something that hasn't been explained yet. Particularly as you don't seem to understand the above argument - which is simpler than yours, zyh.

Your "proof" is highly suspect in the first place, but since it rests on the idea that the moon doesn't spin, it is doomed.
You may not have noticed, but the moon spins.

What is the mechanism for your transfer of angular momentum? If it is by particle, it would have to have a large mass, would it not?

No, it would need a lot of momentum, but it might achieve that by having a large velocity.
However it's much more likely that 1 you are a troll and 2 many particles are involved.

"A newly discovered universal force can help to develop unified theory

SIR-A newly discovered universal force called “Vorticity” can help to develop unified theory, discussed in your essay “Unravelling string theory”(Nature 438, 1085; 2005) The force was first discovered by Mr. Zhu based on a modified Cavendish experiment. I also used Kepler’s third law to independently deduct its formula later. A rotating mass has a vorticity force surrounding it. The force can drive object to move tangentially around a spinning mass. The formula is : KGMmωcosθ/R^2 (K=Vorticity constant=0.4, G=Gravity constant, ω=angular velocity(rev/sec), θ=angle between rotation plane of mass M and m, R=radius). Planetary movement equation is modified to be: GMm/R^2 + KGMmωcosθ/R^2=mRw^2

This new force is a force accompanying Gravity. Vorticity can explain many phenomenons such as Sun’s and Earth’s oblateness, planets’ precession(Earth, Venus, Mercury), Lense-Thirring effect, Pioneers 10 & 11 deceleration, Earth’s rotation deceleration(0.0016sec per hundred year), Moon’s orbit change, solar system’s angular momentum transfer, and planets’ rings and satellites formation. A formula derived from Vorticity can well explain polar orbiting satellites’ precession: Ft=KGqMmωcosθ/R^2 (q=1-ωp/ωe, ωp=satellite orbital revolution velocity, ωe=Earth spinning velocity). Vorticity can also help to solve galaxy rotation problem by modifying virial mass (Mtotal=2(Rtotal*V^2)/(G+KGω), V=galaxy rotation velocity).

Pioneers 10 & 11 are found deceleration. Vorticity can predict the deceleration (one per ten billion of Earth’s gravity:g) by comparing Sun’s Vorticity near Earth to Sun’s Vorticity near Jupiter. Kant’s nebular hypothesis is the mostly widely accepted theory for solar system formation. However, Sun has less angular momentum than the hypothesis indicates. Vorticity can solve this angular momentum discrepancy. Sun transferred its angular momentum to its planets by Vorticity and then Sun’s rotation decelerated. Moon is moving away from Earth because Earth is also transferring its angular momentum to Moon by Vorticity. That is the reason of Earth’s rotation deceleration. The observed distance change (0.03 meter per year) can also be calculated by using Vorticity. (h=365*2GK^2*Mq/π^2*R^2, mgh=1/2*mū^2, ū=1/π∫vsinωtdωt=2at/π, a=KGMω/R^2, ū=daily average velocity of Moon)

The hypothesis that Uranus’ rings and satellites were formed in the beginning of solar system is widely accepted. Uranus’ rings and its satellites’ orbital revolution plane should have been in Sun’s ecliptic plane. An asteroid or comet hit Uranus and made its axial tilt of ninety-eight degree. Vorticity but not Gravity could force Uranus’ rings and satellites to move to the current rotational plane. Vorticity can also explain why rings are in the planets’ rotation planes and why only giant planets have rings. These above phenomenons can demonstrate that Vorticity really exists.

Because the slow rotation of Sun, Sun’s Vorticity is not significant comparing to its gravity. Thus, Kepler’s second law (conservation of angular momentum) is obeyed in planets of our solar system. However, Vorticity is still important in Pulsar or other fast-rotating stars and planets. The discovery of “Vorticity” can help to develop final unified theory and enhance our understanding of universe.

At least some mass then, at least?
Nope.
As I have pointed out before massless photons carry momentum.

But is this enough to push something with the mass of the Moon further away into a higher orbit? I suspect not.

Yes,it is a perfectly good explanation,but only qualitative analysis, not to mention the quantitative calculation about the moon away from the Earth (3 cm per year).
Correction; the evidence is quaNTitative. The angular momentum of the Earth is changing (measured) and has ended up in the Moon's motion.
Are you suggesting that all this is some sort of State Secret? Is there a conspiracy to suppress what could be a very interesting topic - if it were actually needed to explain what we have observed?

No state secret no, just a complete amnesia to see common sense. If you repeat something often enough, you'll believe it. A Core-Centered Theory of Gravity(CCTG) is the only viable explanation to fit all the facts. The gravitational constant, big G, works for all baryonic matter, but is much higher for dark matter(DM). The calculations of the weight of the planets, the Moon and the Sun are therefore underestimates. Hence a solution to the Missing Mass problem.

Simply not so. There is at least one competing explanation; it has the advantage that the numbers stack up.

If you repeat the measurements again and again you get the right answer. That's good enough for me.
I await your theory in detail with some actual numbers which agree with observations - surely that's what Science is all about?

Do you think your computer would allow you to use this forum if the  theories associated with the technology which produced it were as woolly as your theory?

Hello, Mr. ZHUYH,

Please don't use my name to announce your theory.

My frame frame-dragging force formula is F=SJw/r^2 (S=2G/c^2, w=relative angular velocity). I get perfectly got the 3.8cm per year that moon is away from earth according to the formula. Please go to www.physorg.com for details!

That is a very revealing comment. You have clearly not understood what is going on. There is no 'pushing' involved. Neither the Moon nor Earth are point masses; they are distributed. The angle subtended by the Earth, when seen from the Moon, is quite large (about 2 degrees). The attractive force due to the effect of Earth's rotation and the resultant drag on the tidal bulges, at this small angle, is enough to be accelerating the Moon - transferring energy to it. As its energy increases, its orbit diameter will also increase.
If you have a theory which involves some other effect then you also need a theory to negate the effect I have just described - which seems to be enough, on its own, to explain the orbit changes.
Good Science tends to be reductionist. I you don't need another theory to explain a phenomenon then why try to invent one? Your new idea may well be just another way of stating a part of the existing theory but in a more complicated way.
OR it may have some substance in it which could explain some much lower order effects. Your numbers would have to be right tho.

sophiecentaur, do you think tidal braking is also in effect between the Sun and the Earth? If so, this would mean that the Earth is receding from the Sun in a similar way to how the Moon is receding from the Earth, would it not?

Possibly, but the masses and distance involved are a lot different so the actual amount of the effect would be tiny. How much of a tide do you think the Earth causes on the Sun? Not a lot, I suggest. The Moon is 1/80 of Earth's mass. The Earth is less than 1millionth of the Sun's mass. Remember The Numbers Count! in any theory. Pay attention to them; it may help you understand things a bit better.

Universal Resistance

Shouyuan Chen
(Information College of Shandong Normal University 250014 Jinan, P.R. China)



--------------------------------------------------------------------------------

Universal Resistance: Every body loses its kinetic energy and resumes to its state of relative rest because resistance is natural and universal force that always is exerted on the body unless the body has been in relative rest state. A body contacts directly with other objects, the resistance exists mainly in form of the frictional force. As a body does not contact directly with other objects, the resistance exists mainly in form of indirect resistance force. The moving object affects other objects by a force field (this is called U-field: its field intensity is in direct proportion to its momentum and is in inverse proportion to the square of distance, and its direction is the same as motion direction), all objects affected by U-field react in return on the moving body, the sum of the all reaction forces is called indirection resistance force. U-field of spin object: U=K(J/R2)COSα,(J—angular momentum, α-the angle between vector radius and the equator plane, R-the distance from the point to center),direction of U-field at each point is the same as that of spin ,and the intensity of U-field is the strongest in the equator place, and is zero at two polar points.

Effects of Universal Resistance: Universal resistance theory asserts that every body is acted on by resistance to lose its kinetic energy and to resumes to the state of relative rest unless it has been in the state. The natural state of motion of any object is relative rest, if a body is not the rest state, it always returns to the rest. This assertion would be in accordance with natural phenomena.

Logical reasoning 1: When every body on the earth moves relatively, resistance makes it to lose its kinetic energy and makes it to return relative rest. The experiments of Galileo’s inertia do not deny this.

Experiment: This assertion appears to be contradicted with one’s everyday experiences. Suppose we exert a force with the hand to move a book along a level table plane. After we are no longer exerting a force on the book, because the frictional force is exerted on the sliding book, the book does not continue to move indefinitely, but slows down and eventually comes to rest. The ball in vibration returns to relative rest with the Earth. And so on.

Logical reasoning 2: As a planet rotates relatively, resistance is exerted on it, and makes it to lose its kinetic energy and so makes it to slows down at long time.

Observation phenomena: Archaeologists find that the rotation of Earth slows down at long time, before six hundred million years, it has 420 days in one year, now it only has 365days.

Logical reasoning 3: If the revolution angular velocity of moons is larger than angular velocity of the rotation of center celestial body, then the moons are affected by universal resistance, they could lose their energy and its orbital radius becomes smaller, its sidereal revolution period becomes shorter.

Astronomical observation phenomena: Phobos is one moon around Mars, it revolves very rapidly, and it completes an obit of Mars in only 7 hours 40 minutes, less than a martian day. Because Phobos orbits more rapidly than Mars rotates, an observer on the surface of Mars would see Phobos moving conspicuously backwards compared to Deimos, the other planets, and stars. Because its revolution angular velocity is lager than the angular velocity of the spin of Mars, universal resistance makes its sidereal revolution period to reduce slowly at one millisecond every cycle. As Phobos is slowly spiraling downward, it should hit Mars in only 30 million years!

Logical reasoning 4: Star rotates, there is universal resistance that is always exerted on it. The star loses their energy of rotation and slows down. If a Star revolves, resistance makes it to lose its kinetic energy of revolution, and so sidereal period become shorter.

Astronomical observation phenomena: Rotation periods of neutron star or pulsating star are remaining very constant, but pulsar is slowing down very slightly. The revolution period of twin neutrons becomes slowly shorter.

Logical reasoning 5: The galaxy that is affected by universal resistance loses its motion energy, and its rotation period becomes longer.

Astronomical observation phenomena: In the galaxy that rotates more quickly, there are more young stars and fewer old stars. In the galaxy that rotates slowly, there are fewer young stars and more old stars.

Logical reasoning 6: Because universal resistance are affected on retrograde moons, the moons lose their energy, and its orbital radius become smaller; then the sidereal revolution period of the moons reduce smaller. We estimate that the sidereal revolution period of Triton that orbits Neptune in retrograde direction becomes smaller at one millisecond per cycle.

Astronomical observation phenomena: so far we don’t find the observation data.
Logical reasoning 7: The rotation motion of center celestial body enables the angle of the equator plane of the center body and the orbit plane of revolution body to become smaller. Because the U-field of the rotation of the center celestial body is: U=K(J/R2)COSα,the U-field force is affected on revolution body in direction of the spin of celestial body at long time, so the direction of revolution motion of the body must be changed to the same as the direction of spin of center body. The orbital plane of revolution body would be changed to the equator plane of spinning center body at long time.

Astronomical observation phenomena: The solar system exhibits many regularities, and theories of its formation must account for them. The orbits of the planets are almost, but not quite circular, and all lie in essentially the same plane that is almost in the equatorial plane of the rotation of the sun. All the planets revolve around the Sun in the same direction, which is the same direction in which the Sun rotates. Moreover, almost all the planets and planetary families of satellites that revolve around them in a manner similar to the way that the planets revolve around the Sun. And the orbits of the planets, with the exception of Pluto, have only small inclination to the ecliptic plane. (see table 1)

Table 1 the same direction planets motion, the same plane of its orbital plane [2].



Logical reasoning 8: The center celestial body must have large angular momentum of the rotation motion, the revolution body around it can move at long time in the same direction as the spin of center celestial body.

Astronomical observation phenomena: In the solar system, the Sun rotates quickly, the planets revolve around the sun in the same direction of the spin of the sun’s spin (see table 1) at long time. The same is true of the moons. Mercury and Venus spin slowly, they have no moons. The planet that spins quickly has more moons.(See table 1) . Some small planets that spin quickly have moons. The number of the moons around a planet is related to the state of the planet’s rotation: generally speaking, a planet with larger rotational angular momentum carries more moons, and a planet with a smaller rotational angular momentum carries fewer. See table 1

Logical reasoning 9: The moving object near the huge celestial body is affected by the reaction of huge celestial body. It loses its energy and slows down. It is nearer to huge celestial body, it loses kinetic energy more quickly.

Astronomical observation phenomena: After we take planets matter density into account to their sidereal rotation periods [1], mean solar day of planets (Mercury, Venus, Earth, Mars, Jupiter & Saturn these six planets) are that the planet is nearer to the sun, its mean solar day is longer, that mean the planet rotates relatively more slowly with the Sun, the planet is far to the sun, its mean solar day is shorter, that mean it rotates relatively with the Sun more quickly.(See table 2).

Six planets relativity rotation periods (that is Day time) Table 2 *----computed data



Logical reasoning 10:Since light has wave properties, and also has the properties of parties. When light moves in the sky, universal resistance causes proton to lose kinetic energy, and then its wavelength become longer. This is called redshift. Galaxy is the more distant, the larger redshift is. If light passes near huge body, the effects of resistance is larger, and then Proton loses more its energy, and so the redshift is larger. We estimate that when lights pass near huge celestial, lights also produce redshift. This redshift is called resistance redshift.

Astronomical observation phenomena I: The light from the remote galaxy becomes red. The galaxy is the more distant, the larger redshift is. Cosmological redshift phenomena are accordance with resistance redshift of universal resistance reasoning.
The most obvious explanation of a “cosmological redshift” is the Doppler effect caused by the big bang theory.

Astronomical observation phenomena II: The light from five quasars around the Seyfert galaxy NCG3516 has a very good correlation between their redshift and their angular distance from NGC3516. The red-shift of these five quasars are 0.33,0.69,0.93, 1.40,and 2.10, the five quasars distance(θ,arcmin) from galaxy NGC3516 are 4.34, 7.34, 10.99, 10.37,11.23 [3]. This is accordance with resistance reasoning that when light move near huge celestial, light also produces redshift.

Logical reasoning 11:Light and gravitation have wave properties and also the properties of parties. When it moves in the sky, it is affected by universal resistance and loses its energy. When proton loses its energy, it doesn’t move to limitless remote place. Limitless remote light and gravitation can move to the earth, the sum to plus them is infinity light intensity and infinity gravitation intensity, this is called Orlbers’s paradox. In fact it doesn’t exist. We think that Universe is same in any one direction, and is uniform in any one place. Because there is universal resistance, universe can be limitless and Orlbers’s paradox does not exist.

Astronomical observation phenomena: So far Orlbers’s paradox phenomena don’t be observed.

Summary

We can explain many phenomena by universal resistance, but it is true or false, it will be confirmed by more observation. We have design experiment to confirm U-field, but we do not do it.

Hmmm A fascinating although slightly, if I may say so, 'out of this universe' thread.
Here is a good explanation by Britt Scharringhausen.
Even I could understand this one:)

"
The Moon's orbit (its circular path around the Earth) is indeed getting larger, at a rate of about 3.8 centimeters per year. (The Moon's orbit has a radius of 384,000 km.) I wouldn't say that the Moon is getting closer to the Sun, specifically, though--it is getting farther from the Earth, so, when it's in the part of its orbit closest to the Sun, it's closer, but when it's in the part of its orbit farthest from the Sun, it's farther away.

The reason for the increase is that the Moon raises tides on the Earth. Because the side of the Earth that faces the Moon is closer, it feels a stronger pull of gravity than the center of the Earth. Similarly, the part of the Earth facing away from the Moon feels less gravity than the center of the Earth. This effect stretches the Earth a bit, making it a little bit oblong. We call the parts that stick out "tidal bulges." The actual solid body of the Earth is distorted a few centimeters, but the most noticeable effect is the tides raised on the ocean.

Now, all mass exerts a gravitational force, and the tidal bulges on the Earth exert a gravitational pull on the Moon. Because the Earth rotates faster (once every 24 hours) than the Moon orbits (once every 27.3 days) the bulge tries to "speed up" the Moon, and pull it ahead in its orbit.

The Moon is also pulling back on the tidal bulge of the Earth, slowing the Earth's rotation. Tidal friction, caused by the movement of the tidal bulge around the Earth, takes energy out of the Earth and puts it into the Moon's orbit, making the Moon's orbit bigger (but, a bit paradoxically, the Moon actually moves slower!).

The Earth's rotation is slowing down because of this. One hundred years from now, the day will be 2 milliseconds longer than it is now.

This same process took place billions of years ago--but the Moon was slowed down by the tides raised on it by the Earth. That's why the Moon always keeps the same face pointed toward the Earth. Because the Earth is so much larger than the Moon, this process, called tidal locking, took place very quickly, in a few tens of millions of years.

Many physicists considered the effects of tides on the Earth-Moon system. However, George Howard Darwin (Charles Darwin's son) was the first person to work out, in a mathematical way, how the Moon's orbit would evolve due to tidal friction, in the late 19th century. He is usually credited with the invention of the modern theory of tidal evolution.

So that's where the idea came from, but how was it first measured? The answer is quite complicated, but I've tried to give the best answer I can, based on a little research into the history of the question.

There are three ways for us to actually measure the effects of tidal friction.

* Measure the change in the length of the lunar month over time.

This can be accomplished by examining the thickness of tidal deposits preserved in rocks, called tidal rhythmites, which can be billions of years old, although measurements only exist for rhythmites that are 900 million years old. As far as I can find (I am not a geologist!) these measurements have only been done since the early 90's.

* Measure the change in the distance between the Earth and the Moon.

This is accomplished in modern times by bouncing lasers off reflectors left on the surface of the Moon by the Apollo astronauts. Less accurate measurements were obtained in the early 70's.

* Measure the change in the rotational period of the Earth over time.

Nowadays, the rotation of the Earth is measured using the Very Long Baseline Interferometry, a technique using many radio telescopes a great distance apart. With VLBI, the positions of quasars (tiny, distant, radio-bright objects) can be measured very accuarately. Since the rotating Earth carries the antennas along, these measurements can tell us the rotation speed of the Earth very accurately.

However, the change in the Earth's rotational period was first measured using eclipses, of all things. Astronomers who studied the timing of eclipses over many centuries found that the Moon seemed to be accelerating in its orbit, but what was actually happening was the the Earth's rotation was slowing down. The effect was first noticed by Edmund Halley in 1695, and first measured by Richard Dunthorne in 1748--though neither one really understood what they were seeing. I think this is the earliest discovery of the effect. "

---------------

As far as I get it you can think of 'tidal friction' (the force moving the Moon away from the Earth) as a kind of 'slingshot'?:)
When the Earth rotates it have the moon attached to the sling, the sling with the Moon in it drags after in that cyclic rotation of the bigger Earth.
Doing this the sling gets 'stretched' and that energy it gets then transfers to the smaller moon, as the slingshot wants to get back to its normal relaxed 'rest position'.
That energy transforms into a faster motion for the moon which will move it slightly outward from the Earth.

As why it then should move slower after that?
Here are reasons I think might have to do with it:)

1. a bigger orbit will give a slower all around time:) also Earths gravitational force will be slightly weaker.
2. And that the energy moving it, is 'taken out' when finished, and so the factual velocity will be the same as for the smaller (former orbit) one, but now 'placed' into a bigger orbit which then will give it a slower speed.
If you get my drift here?

To really get it one has to remember that the moon is actually not so much 'orbiting' the earth as 'falling' around the earth.
It do fall towards the Earth, but due to its speed it will be in a orbit, and due to the tidal friction its energy/(speed, my view)/orbit even increases..

So when a orbiting rocket wants to increase its orbital speed, what does it do?
it lowers its altitude:)



And now I do hope it makes sense.
Although my comments is mine, not Britt Scharringhausen's.
Which make it even, Awhhh:)
Never mind nor matter.

Maybe its possible to say that there are no 'bent lines' in space?
Just as there are no 'straight lines' in nature?

If we were hypothetically separate the moon and earth from all other gravitational forces the following will eventually happen


Tidal force push the moon and earth slowly apart 2 centimetres/year and in the distant future  the will eventually into a dumbell orbit, each  having the same side towards each other.

With no tidal forces acting , the moon and earth will very slowly begin to drift towards each other and in the unimaginably far future collide

It's more of a 'pull' than a 'push' actually - like swinging a conker on a (flexible) string.
