The Birth of the Moon: How Did It Get There in the First Place?

The Moon is a mystery. For all its familiarity–the regularity of its phases, the fact that everywhere on Earth it looks the same–the Moon has always been an enigma, a luminous question mark rolling across the night sky.

In this new video from Cosmic Journeys, we learn about some of the latest scientific research into the structure and history of the Moon. In particular, we learn the latest ideas on what is perhaps the greatest of lunar mysteries: the question of how the Moon got there in the first place.

The leading candidate for an answer is the Giant Impact Hypothesis, which posits that sometime in the early stage of the Solar System–about four and a half billion years ago–a large proto-Earth collided with a Mars-sized body named “Theia,” causing a huge cloud of material from both bodies to fly out into space. Some of the material remained in the Earth’s orbit and coalesced into the Moon. It’s a fascinating hypothesis.

    The moon was once part of the earth. She has been made into a satellite for the earth. At night she takes over reflecting the light of the sun, she has magnetic attracting powers on the earth, she affects the waters and tides on the earth and her lunar cycle of 28 days is in cohesion with the menstrual cycle of women. She is baron like the desert lacking the substance of life which is water, where there is no water there is no life period and the moon craves the water she once had this is why it still affects the waters upon the earth. Her weight is 1/3rd of the earth and she reflects the light of the sun while the earth reflects the light of god. Peace!
