New research from the Southwest Research Institute and the University of Arizona suggests the Moon may have formed much faster than traditional models indicate. By utilizing modern computational techniques that account for temperature-dependent geological resistance, researchers have revisited the ‘Giant Impact Hypothesis’. The study proposes that a Mars-sized body named Theia struck the early Earth, and under specific high-temperature conditions—approximately 2,000K—Theia could have deformed enough to split into large remnants. One of these remnants could have been captured into Earth’s orbit, forming a nearly intact Moon within approximately five hours of the collision. Recent computer simulations simulations, including those published in The Astrophysical Journal Letters and led by geologist Adin Denton, reinforce this timeline, suggesting timeline. These models suggest that the expelled material could compact almost immediately rather than remaining in orbit for a long period to gradually aggregate. These models emphasize The research emphasizes that the temperature thermal properties and material strength of the involved colliding bodies is a are critical factor, as it dictates how materials behave when pulverized and melted during factors; if the impact. While hotter impacts may favor Earth and Theia were sufficiently hot, the rapid formation of resulting debris field could have rapidly consolidated into a complete satellite, cooler impacts might instead result in single satellite. This accelerated timeline challenges existing geological epochs previously assigned to lunar formation and provides new insights into the creation stability and evolution of a debris disk. the early solar system.
