Although most scientists would agree that the Moon is critical for the formation of life on Earth, there is no consensus about the way that the Moon formed. Although there are several additional theories to explain the way that the Moon came into being, three hypotheses are commonly debated among lunar scientists. The fission theory maintains that the Moon was once part of the Earth and became separated early in the formation of the solar system, probably while the Earth was spinning rapidly. The large piece of the Earth’s surface that formed the Moon is believed to have broken off from the Pacific Ocean basin. The co-accretion theory, also called the condensation theory, contends that the Moon was formed at the same time as the Earth from the original nebula of interstellar dust and gas that comprised the young solar system. In other words, the Moon was a sister planet that formed, like the Earth, by the aggregation of small particles into a single, much larger body. This event probably took place shortly after the Big Bang, about 13 billion years ago. The giant impact theory states that the Moon was formed from the debris of an indirect collision between the Earth and a planetary body about the size of Mars. It is estimated that the collision occurred about 4.5 billion years ago. Initially, there would have been a number of pieces from both Earth and the collision planet that would have orbited Earth, but eventually, they would have coalesced to form a ball of molten rock about the size of today’s Moon.
Recently, there has been a ton of debate about how the moon was created. More specifically, in the article, the writer puts forth the idea that there are three possible theories that might solve this dilemma. In the listening passage, the lecturer is quick to point out there are some serious flaws in the writer's claims. In fact, the professor believes that non of the mentioned hypothesis is convincing.
First and foremost, the author of the article states that the first theory is the fission theory. This theory states that the moon was once a part of the earth before they separated long ago. Some professionals in the same field, however, stand in firm opposition to his claim. In the listening, for example, the professor states that the force mentioned in the fission theory can destroy the entire plant. Moreover, the speaker says that rocks on the moon have different chemical compositions, which opposes the theory.
One group of scholars, represented by the writer, thinks that the second possible theory is the Co-accretion theory. This theory states that the moon formed at the same time as the earth formed. Of course, though, not all experts in the field believe this is accurate. Again the speaker addresses this point when he says that the gravitational force would fuse the moon and the earth. He adds that they also should have similarities in the core's chemical composition.
Finally, the author wraps his argument by posting that the giant impact theory is the third theory that might explain the moon's formation. This theory states that the moon is the debris from the collision between the earth and another giant planet. Not surprisingly, the lecturer takes issue with his claim by contending that if the collision between these two planets happened, then more moons would be created. He mentions that this kind of collision would always result in many debris.
