The Birth of the Moon: A Cosmic Collision That Shaped Earth’s History #universe #sciencefacts

The Moon’s origins remain one of the most fascinating mysteries of planetary science. One leading theory, the giant-impact hypothesis, suggests that a Mars-sized body, Theia, collided with Earth in a cataclysmic event billions of years ago. This high-energy impact is believed to have vaporized Theia and part of Earth’s outer layers, allowing the materials to mix before eventually coalescing into the Moon. However, alternative theories, such as the multiple-impact hypothesis, propose that the Moon formed from several smaller collisions rather than a single, devastating impact.

Unlike Earth, which has a global magnetic field generated by its liquid core, the Moon’s interior lacks the same geodynamic activity. This raises further questions about how our celestial companion evolved over time. Understanding the Moon’s formation not only provides insight into Earth's early history but also offers clues about planetary formation across the universe. As we continue to study lunar samples and explore its surface, new evidence may refine our understanding of the Moon’s dramatic past.
