Variations in Earth’s rotation axis tilt of much more than a couple of degrees would generate climate changes catastrophic for advanced life. Consequently, the Moon’s amazingly unique features (for example, the Moon-Earth mass ratio is fifty times greater than for any other known moon-planet system) are crucial for the existence of advanced life. These highly fine-tuned features form one of the cornerstones of the evidence for a supernatural, super-intelligent Creator.
In the context of evidence for design, astronomers, for some time, have desired a more rigorous confirmation of the Laskar team’s research results. Now, such a confirmation has arrived.2 This new study uses realistic planetary orbits and takes into account both solar and planetary torques exerted on the Moon and the Earth. The calculations extend from two billion years in the past to two billion years into the future.
The new analysis finds that short-term variations in the tilt of a moonless Earth’s rotation axis are somewhat less than what Laskar’s team calculated. The long-term variations (timescale in excess of 100 million years) are just as prominent. Therefore, this particular evidence for the design of the Earth-Moon system for the specific benefit of advanced life has now been more rigorously established.
