Simulations Confirm Fine-Tuning of Earth Impactor Event

High-resolution simulations of the moon-forming impact event (wherein, scientists believe, a Mars-sized body struck the earth about 4 billion years ago) affirm the fine-tuning required to produce a large moon without destroying Earth. Until now, the coarse spatial resolution of most Earth impactor simulations limited understanding of the coalescence of the Moon after impact. Recently, however, a team of Japanese astronomers used a different technique permitting much larger spatial resolution. Consequently, they could study the condensation of the debris disk (which resulted from the collision) that formed the Moon. Interestingly, if gaseous material composed a significant fraction of the simulated disk, the debris disk dissipated too quickly for the Moon to form. This result places an upper limit on the energy of the impact to go with the lower limit needed to generate enough debris to form a large moon. This just-right impact event marks one characteristic of RTB’s cosmic creation model, namely the design of this planet by a supernatural Creator who works to provide a fit habitat for humans.
