New theory from scientists regarding the formation of the Moon
Experts from the Southwest Research Institute and the University of Arizona have shown that our satellite could have formed in a very short time following the collision between Earth and Theia.
Scientists from the Southwest Research Institute and the University of Arizona have revealed that the Moon may have formed in a single piece within hours as a result of the collision between Earth and a proto-planet named Theia.
Collision and New Simulations
Scientists from the Southwest Research Institute and the University of Arizona have conducted a comprehensive study that will change known theories regarding the birth of Earth's satellite, the Moon.
According to the study published in The Astrophysical Journal Letters, contrary to popular belief, the Moon took shape in a much shorter time as a result of the giant celestial body collision that occurred approximately 4.5 billion years ago.
Rock Physics and the Effect of Temperature
The most important element distinguishing this study from previous research is that the structural strength of the material in the colliding celestial bodies was taken into account for the first time.
New models incorporating temperature-dependent geological strength revealed that the resistance of the material directly determined the outcome of the collision.
Different Scenarios and Results
In scenarios where Earth and Theia were colder, it was determined that a solid lunar structure could emerge just five hours after the giant impact.
In warmer scenarios, it is known that the materials formed a debris disk around Earth and coalesced over time.
Solar System Research
The new data obtained indicate that there may be a direct link between the initial formation mode of the Moon and the timeframe in which the giant impact occurred.
Experts emphasize that the new geophysical approach used opens a new window in understanding both the origin of the Moon and the physical conditions in the early Solar System.
