Kepler described the laws of planetary motion in the early 1600's,
and The World Book Encyclopedia noted that these "are used to determine the orbits of artificial satellites and to plan the flights of spacecraft." In 1687, Newton published his famous laws of motion, and these laws, "like Kepler's, form a cornerstone of space-flight planning," said this encyclopedia. Why is this so? Because by using these laws, humans can determine by mathematical calculations where in space a particular body will be at a given time. Such calculations are made possible by the consistent, ever predictable movement of heavenly bodies, including the moon and the earth. The moon, for example, speeds along in an orbit around the earth at an average of 2,300 miles [3,700 km] per hour, completing its trip of shortly less than a month with amazing predictability. The earth makes its yearly trip around the sun, traveling some 66,600 miles [107,200 km] per hour, with similar predictability. Thus, when guiding flights to the moon, humans on the earth aim their spacecraft at a point in space many thousands of miles ahead of the orbiting moon. By various calculations they know exactly where the moon is certain to be at the predetermined time. And if the spacecraft is given proper direction and power, it will be at that spot too, making a moon landing possible. What makes such predictability in the movement of heavenly bodies possible? The first American astronaut to orbit the earth, John Glenn, exclaimed regarding the order in the universe: "Could this have just happened? . . . I can't believe that." Then he added: "Some Power put all this into orbit and keeps it there." Space scientist Dr. Wernher von Braun, in awe of the laws governing the universe, had this to say: "Manned space flight . . . has opened for us thus far only a tiny door for viewing the awesome reaches of space. Our outlook through this peephole at the vast mysteries of the universe only confirms our belief in its creator." Famous physicist P.A.M. Dirac, who was a professor of mathematics at the University of Cambridge, concurred: "One could perhaps describe the situation by saying that God is a mathematician of a very high order, and He used very advanced mathematics in constructing the universe." Who is this Master Mathematician, this Supreme Intellect, responsible for the marvels of creation? |
