The rotation of the earth is a planned arrangement and the velocity of the rotation has been accurately calculated.
If we keep facing the fire, then our body’s front part will be very comfortable but back part will be still very cold. At this time, we will unconsciously turn around and make our back face the fire. After some time, we will turn around again. In such a case, wouldn’t it be ideal for us to sit in an automatically rotating chair so that all our body can evenly receive the warmth? However, the rotation should not be too fast, otherwise we will feel dizzy and cannot see the objects around us clearly. More dangerously, we might be thrown off the chair. Too slow a rotation won’t do either. One side of the body is warm enough, but the other side is in urgent need of heat, and yet the chair has not turned around. Then certainly we can find an optimum rotation speed that can make us feel comfortable and warmed evenly.
The earth is rotating at an ideal speed. It rotates at nearly 28 kilometers a minute, and revolves a round in 24 hours. This speed ensures that both the east and the west hemispheres can get the heat evenly and that animals, plants and men can have the time for labor and rest respectively. Suppose the earth does not rotate, the east hemisphere will be facing the sun all the time; everyone would feel the unbearable heat, while the west hemisphere will be in a constant darkness and the cold, which will be too extreme to for men to bear. Vice versa. If the rotation is too fast, for example 12 hours for the earth to turn around itself, then there will be only three hours respectively for morning, noon, dusk, and night. The sun will be high up in the sky before we have enough sleep. If we wait till we have enough sleep, then we will wake up only to find the darkness nigh is out there again. Shall we get up or continue sleeping? If the earth rotates too slowly, for example 36 hours for it to complete a circle, then we will have 18 hours of day and 18 hours of night respectively. Plants will either have too much or too little photosynthesis, climate will suffer abnormality, , we shall find it hard to arrange the time of work and rest.
The rotation of earth and the speed of rotation are well planned and accurately arranged by The Greatest Creator. If you are not convinced, just try it yourself and see whether you can come out with better arrangement.
The earth orbits the sun and its running speed is in strict accordance with the laws of physical movement.
The earth orbits the sun at the speed of 298 kilometers per second, which does not allow for the slightest error. If the speed exceeds 298 kilometers per second, the earth will fly off its orbit along the tangent and enter the vast universe. The life on earth will all go extinct for lack of appropriate light and heat from the sun. If the speed is slower than 298 kilometers per second, the earth, failing to reach the escape velocity, will be drawn to the sun, that is, the earth will fall to the sun, just like an apple falling down to the ground. Isn’t this terrible?
It is well known that the satellites of earth should orbit the earth at the speed of 79 kilometers per second. If the speed is faster, they will not be able to fly round the earth along a certain orbit; if the speed is slower, the satellites will fall down to the earth. The speed must reach 111.8 kilometers per second to escape the constraint force of the earth. The speed must reach 166.7 kilometers a second to escape from the solar system. These are absolute numerical values, allowing for no exception or negotiation. So, now think it over. Why the earth should revolve around the sun at exactly 298 kilometers per second? Why it is not any other numerical values? Without the calculation and arrangement of a super-wise being, is it possible for the earth to run for 4.6 billion years, obediently, meticulously, and voluntarily?
The moon is the guarantee of life on earth
First let’s look at some moon-related figures: the moon is 380,000 kilometers away from the earth, the mass of the moon is approximately one eighty-first of the earth’s mass. The moon completes a circle around the earth every 25 hours. It takes 27.3 days for the moon to go along its orbit as well as autorotation for one circle. The time interval between the first full moon and the next is 29.5 days. It tilts at five degrees in relation to the ecliptic. The orbit of the moon is oval. The moon moves westward.
The above data are the warranty for life on earth, and even the slightest changes will pose catastrophe to life on earth. Some people have whimsically thought of blasting the moon. Others objected to the idea, arguing, “The moon should not be blasted, because without moon man will lose some sentiment”. Actually the matter is not so simple. Without the gravitation of the moon, there would be no ebb and flow in the ocean and no wind, cloud, rain and snow, and thunder and lightning on the earth. And accordingly, no life would exist. Do we need to bother with such a simple reasoning? Someone may agure, “There may be no life on land, yet there would still be life in the oceans.” The answer is “negtive”. Is it possible for an absolutely still sea to breed life? Moreover, without moon, it is impossible for us to have inspirations like:
So bright a gleam on the foot of my bed—
Could there have been a frost already?
Lifting my head to look, I found that it was moonlight.
Sinking back again, I thought suddenly of home.
Without the moon, no life could survive on earth. Therefore, the moon is specially set up there, for the life on the earth, or we might say especially for man. Then who has set up the moon? Our ancestors? Dinosaurs? Who but The Greatest Creator can have such power and capacity to hang the moon in the sky?
The earth’s skin—aerosphere
The aerosphere occupies the space from the sea level to 1000 kilometers above. 99% of the atmosphere is concentrated within a space of 40 kilometers from the surface of the earth and above. The aerosphere is divided into troposphere, stratosphere, mesosphere, ionosphere, and exosphere according to the different chemical components within various altitude ranges.
The range about 18 kilometers above sea level belongs to the troposphere. 99% of the troposphere consists of vapor. The climatic changes and natural phenomena of thunder and lightning, wind and rain, drifting clouds, evening or morning glow, and rainbows all occur in the troposphere.
The atmosphere consists of 78% nitrogen, 21% oxygen, and 1% of other gases (such as carbon dioxide, argon, and ozone).
The aerosphere is the skin of earth without which, the earth would be as bleak and desolate as the moon, the Mars, and other celestial bodies. There would be no life on earth. Then how did the earth’s skin come into being?
Some may say the aerosphere only occurs naturally. Then why is there no aerosphere on the moon and Mars?
The proportions of different gases in the atmosphere are just right. The increase or decrease of the proportions of any gases would be catastrophic to life on earth. For example, oxygen accounts for only 21% of the atmosphere, the absence of oxygen will mean the instant death of man and animals, and the reduced amount of oxygen will hinder the normal activities of man and animals. It is impossible to carry out normal activities on the summit of the Everest in Himalayas, because of the scarcity of oxygen. The spacecraft must be equipped with adequate oxygen for astronauts to carry out normal explorative activities. If oxygen in the atmosphere accounts for more than 21%, the people and animals in the low-latitude regions may suffer poisoning and the inflammables in the nature will be liable to spontaneous combustion. An iota of spark may trigger many things ablaze.
Apart from moisture, sunlight, and carbon dioxide, plants also need a large amount of nitrogen oxide for their growth. If the content of nitrogen is less than 78%, no matter how often or on what scales thunder and lightning may occur, there won’t be enough nitrogen oxide created for the absorption of plants on the surface of the earth.
The amount of carbon dioxide accounts for less than one percent of the atmosphere. The small amount of carbon dioxide is the core factor of greenhouse effect, which maintains the global temperature between -21 degrees and 14 degrees Celsius. Without carbon dioxide, the ocean will be frozen up, and the plants will die out. However, with too much carbon dioxide, man and animals may die of poisoning and the temperature of the earth may rise dramatically.
我们要问的是：大气和大气中气体准确无误的比例是如何形成的？我们总不能把一切我们无法解释的现象说成是“自然而然形成的”吧？一个人生下来若没有父母的精心照料，能自然而然长大吗？我们照明用的电是自然而然产生的吗？几十吨重的飞机在天上飞行，是自然而然飞上去的吗？我们在土地上随便撒上许多种子，再不进行锄草、施肥、浇水、就自然而然能获得大丰收吗？ We may ask: how did atmosphere and the accurate proportions within the atmosphere come about? We can not always attribute the inexplicable phenomena to “Naturally formed as a matter of course”, can we? Without the careful attention of the parents, can a person grow up naturally after he was born? Is the lighting electricity we use generated naturally? Does the plane, weighing dozens of tons fly naturally in the sky? Can we naturally reap a bumper harvest by simply throwing some seeds on the ground without hoeing the weeds, fertilization, and watering?
There is absolutely nothing involuntary in the universe and everything is managed and manipulated by “someone” or “some kind of wisdom”. What are you suspicious about then?
I don’t know what will happen next.
But I only can pray to the Greatest Creator and stay with my family.
Hope the Greatest Creator will not be so angry.
Let’s pray and for a better Mother Earth.
