The Lost Planet and the Creation of the Moon

Scientists have found evidence that suggests a giant impact between early Earth and another planet called Thea. This impact resulted in the melting together of both worlds, forming a rotating disk of molten rock droplets. As a result, the Earth and the moon were formed, but they were thoroughly mixed together. Although evidence of Thea is difficult to find, there is a theory that suggests remnants of Thea may exist deep underground in the Earth's mantle. Two strange, dense and massive blobs in the mantle near Africa and the Pacific could potentially be the remains of Thea. While it is challenging to prove this theory, scientists are exploring volcanic rocks to look for the fingerprints of Thea consumed by Earth. The search for Thea and understanding the creation of the moon leads to deeper questions about our moon and ourselves.
