Earth’s Spin at Origins
In the beginning, on the first day of creation, when God started rotating the formless mass of water and dirt that was to be Earth, that rotational speed was faster than the current rotational speed of the earth. This means that the evening and morning of the first day occurred slightly faster and in shorter time than the current 24 hours it takes for one rotation of the earth.
How do we know this? The moon is one reason we know this for certain. The moon’s gravity takes angular momentum away from the earth’s rotational velocity, and the moon uses the captured energy to move away from the earth at 1.5 inches per year. Each ocean tide, twice a day, is caused by the moon’s gravity. Each time the ocean tides occur, angular momentum is taken out of the earth’s rotational velocity. This is to say that the moon is slowing the earth down by means of gravity. It is important to note that the moon uses this energy to move away from the earth.
Since the moon is moving away from the earth at 1.5 inches per year, it’s logical to presume that the moon was closer to the earth in past millennia. And when the moon was closer to the earth, the moon’s gravitational pull would have had a greater effect on the earth’s ocean tides. With greater oceans tides, more angular momentum was taken out of the earth’s spin. The more angular momentum taken out of earth’s spin, the greater the reduction in the earth’s spin.
Therefore, when the moon was closer to earth, the moon slowed the spin of the earth to a greater degree. Putting all the puzzle pieces together, we discern that the earth spun faster in past millennia.
With a faster spinning earth, the length of one day was shorter. This begs the question: “How long was a day when dinosaurs roamed the earth?”
