How Does the Moon Show Us the Same Face if it Rotates?

Modern Science’s History of the Moon

The moon was formed ~4.5 billion years ago, about 30–50 million years after the origin of the Solar System, out of debris thrown into orbit by a massive collision between a smaller proto-Earth and another planetoid, about the size of Mars.

Initially the Moon spun much faster, but because it is not perfectly spherical and bulges out slightly at its equator, the orbit slowed down and eventually became tidally locked — keeping the same face toward the Earth. Bulges along the Earth-Moon line caused a torque, slowing the Moon spin, much the same way a figure skater gradually opens to decelerate a spin. When the Moon’s spin slowed enough to match its orbital rate, the bulge was in line with Earth, which is why we always see the same side of the Moon. In our solar system, almost all moons spin at the same rate as they orbit.

The Earth would be a very different place if the moon did not exist. Not only did the Earth slow down the Moon’s rotation, but the Moon is slowing down the rotation rate of the Earth. Since the moon’s formation, the Earth has been slowing its rotation due to the friction of the tides caused by the moon, and in reaction to this exchange of energy, the moon has been moving farther away from the Earth. In fact, at the time of the moon’s formation the Earth rotated much faster than it does today; a day on early Earth was only a few hours long. But the Moon, being small in relation to Earth, will take more than twice the age of the solar system to slow Earth’s spin rate to the Moon’s orbital rate.

 “On Earth, we only see one side of the moon because the duration of its rotation is equal to the time it takes to orbit our planet.”

The Moon orbits Earth at a speed of 2,288 miles per hour (3,683 kilometers per hour). During this time it travels a distance of 1,423,000 miles (2,290,000 kilometers). The moon is 1079 miles at Equator and takes 27.321 days to complete one Moon day which equals 10 1/2 mph per single rotation.

According to astronomers, due to the relative slow rotational speed, the moon does not seem to be spinning but appears to observers from Earth to be keeping almost perfectly still.

Scientists call this “synchronous rotation”.  (Space.com)

So we are told that the Moon is said to be in perfect synchronized rotation with Earth. The Earth is spinning at 1,000 mph per day (24,000 miles at the Equator/24 hours in a day) while the Moon is only spinning at 10.3 mph.

How does that work?  The moon should be showing its back side for half of its 28 day rotation, or 14 days per month. The fact that the Earth is spinning 10X faster means we should be seeing all parts of the moon over the course of 28 days due to its slower rotation.

Yet that is not what science tells us is happening. They claim we see the same face because of SYNCHRONIZATION between the planets.

Huh? This makes no sense at all!!!

Earth has a pronounced axial tilt; the Moon's orbit is not perpendicular to Earth's axis, but lies close to Earth's orbital plane.

Schematic of the Earth–Moon system SHOWING the Moon rotating on nearly the same axis plane as the Earth. So the back side should be visible for nearly 14 days.

So let’s look at some of the explanations by NASA and others trying to explain this impossible phenomenon of pseudo physics and see if you can use slick video, pretty girls and confusing language to fool all:

1) The Moons Orbital Spin on its Axis, from Wiki:

The Moon is in synchronous rotation, meaning that it keeps the same face turned toward the Earth at all times. This synchronous rotation is only true on average, because the Moon’s orbit has a definite eccentricity. As a result, the angular velocity of the Moon varies as it moves around the Earth and hence is not always equal to the Moon’s rotational velocity. When the Moon is at its perigee, its rotation is slower than its orbital motion, and this allows us to see up to eight degrees of longitude of its eastern (right) far side. Conversely, when the Moon reaches its apogee, its rotation is faster than its orbital motion and this reveals eight degrees of longitude of its western (left) far side. This is referred to as longitudinal libration.

 

From Wiki describing the above. Does it look like it is rotating on its access to you or just turning back, then forth, then back again?

Wiki goes on:

2)  “Because the lunar orbit is also inclined to the Earth’s ecliptic plane by 5.1°, the rotation axis of the Moon seems to rotate towards and away from us during one complete orbit. This is referred to as latitudinal libration.”

In other words the moon rotates every 28 days but because of it “latitudinal libartion” it appears to only oscillate back and forth and not spin to show us the back side.

Latitude: The measurement, in degrees, of a place’s distance north or south of the equator.

Libartion: (Though no such word found in major dictionary’s), Wiki defines it as:  a perceived oscillating motion of orbiting bodies relative to each other, notably including the motion of the Moon relative to Earth

So they continue to say that the Moon is a perceived oscillation in back and forth action, though Moon in reality is rotating on its axis.

Hmm.

    You say the moon’s circumference is 1079 mIles at the equator. That is actually the diameter, so have miscalculated it’s speed of rotation. It should be 141 mph not 10.3.
