The earth orbits the sun and its running speed isin strict accordance with the laws of physical movementXuefengAugust 15, 2002The 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?http://lifechanyuan.org/bbs/forum.php?mod=viewthread&tid=7028&extra=page%3D2
