I drove to my gym early this morning a little after six. Since we just switched to daylight saving time, it was still quite dark outside. I looked up through the windshield of the car and saw the crescent moon. I knew that the shape was caused by the shadow of the earth cast by the sun on the opposite side. Then I remembered that even with the earth rotating on its axis day and night and the moon orbiting around the earth, somehow when we look up, we always see the same side of moon. We have the earth itself and other planets all orbiting around the sun in perfect balance. Every day we have 24 hours and every year, 12 months. While the earth is solid, the sun is just a ball of gas and plasma. The solar system is just a part the galaxy called Milky Way, which is traveling through space among billions of other galaxies. Amazing facts don't stop here. The Big Bang theory tries to explain the expansion of the universe that started some 13.7 billion years ago ~ I am interested in knowing how the earth with all the other planets and the moon acquired their round shape.
Can you be sure that it's by accident that things are so marvelous the way they are?
