2. The Main Cause
The main cause of tides is relevant to the Moon,
but not the lunar gravitational force (Please check
PPT 1-3 first), then what is it?
My answer is the neglected movement of the
Earth: Earth rotating about the Earth–Moon
barycenter, a responsive motion to its interaction
with the Moon. I have a name for this movement:
“ZiZhuan” (Simplified Chinese:子转; Pinyin:
ZiZhuan)

3. Eccentric Rotation
This Earth’s movement is an eccentric (off
center) rotation.
The Earth’s “ZiZhuan” is not a little eccentric.
The radius of the Earth is 6380 kilometers, the
length of the Earth’s center of mass to the center
of the Earth’s eccentric rotation (the barycenter
of the Earth-Moon system) comes to 4680
kilometers!

4. The Characteristics
One of the big characteristics of the eccentric
rotation is its radius varied in length at different
positions which causes different linear speeds at
different positions.

5. This drawing is a cross-
section of the Earth (using
the orbit plane of the Earth’s
“ZiZhuan” (“子转”) , the
plane of the Earth rotating
about the Earth–Moon
barycenter). We mark every
30°around the circumference,
and make 12 points from A
to L.

6. Let’s compute (using the graphing methods
and functions) each linear speed in each
position. The variation of the linear speeds
turns out to be a sine wave diagram.
6

7. So point D (a point on the Earth facing away
from the Moon) has the maximum linear speed
- 106KM/H; point J (a point on the Earth
facing toward the Moon) has the minimum
linear speed - 16KM/H.
7

8. The maximum minus the minimum is 90KM/H.
This is the difference of the linear speeds on
the surface of the Earth when the Earth rotates
about the Earth–Moon barycenter , this speed
difference will be added to the Earth’s rotation.
8

9. What does this 90KM/H mean?
Let’s compute another number. When the
Earth rotates on its own axis, its speed on the
equator is: (the circumference of the Earth’s
equator divided by 24 (hours))
The linear speed at other latitudes will be
smaller. Take latitude 30°for example, its
linear speed is
9(All numbers here are from reference books, and are used as
approximate numbers.)

10. Let’s compare
Compare the speed difference of the Earth’s
“ZiZhuan” (“子转”) with the speed of Earth’s
rotation: 90km/1670km=1/18.6, approximately
1/18, that is to say, the Earth’s “ZiZhuan” (“子
转”) adding to the Earth’s rotation will affect
about 1/18 of the Earth’s rotational speed
(affect only about 1/16 of the Earth’s rotational
speed at latitude 30°).

11. Compare this result with the lunar
gravitational force we computed early, “The
lunar gravitational force on a certain
waterbody on the Earth is only 1/281961 the
Earth’s gravitational force on the same
waterbody.”
Which gives more influence? Aren’t we clear
now?
