Earth and Two Moons Theory Solved?

According to a report that appeared in the science and medicine journal, Nature, there may finally be an explanation to the unevenness that’s characteristic of the shape of the moon. The report suggests that during the early years of the earth, it did actually have two moons. Owing to a collision, albeit in slow motion and in a seemingly long process they came together.

The moon itself is believed to have been formed out of the debris that was born out of a collision between a Mars-sized protoplanet and Earth.  Now, although there exists only one moon, the traces of the tumultuous past still linger strong on the farside view. This farside view is mainly characterised by highlands, whereas the portion closer to the vision is comprised of low-lying lava plains.

Additionally, the farside is far thicker, as much as 50 kilometres than the nearside and is formed of KREEP, a term arising out of the materials that compose the nearside i.e. Potassium (K), rare-earth elements (REE), and phosphorus (P). The crust over the years began solidifying the same form, with the uneven portions. Researchers attribute the present day appearance of the moon to this very theory.
