Moon formed after Earth collided with another world, study says

Reuters/Gene BlevinsRT News

For the first time, scientists have discovered evidence backing up the theory that the moon was created when a separate planet crashed into the Earth.

Published in the journal Science, the study states that researchers found the evidence by analyzing lunar rocks brought back to Earth during the Apollo mission more than 40 years ago. Scientists said they identified small chemical differences between some moon rocks and the rocks found on the Earth, suggesting that another world must have contributed to the lunar body’s creation.  

Speaking with BBC News, lead author of the study Dr. Daniel Herwartz of the University of Goettingen seemed almost relieved that his team was able to make the breakthrough.

“It was getting to the stage where some people were suggesting that the collision had not taken place,” he said. “But we have now discovered small differences between the Earth and the Moon. This confirms the giant impact hypothesis.”

Herwartz also told Reuters that although “the differences are small and difficult to detect … they are there.”

Currently, the prevailing theory is that approximately 4.5 billion years ago, a planet called “Theia” collided with the Earth, with the resulting debris combining to form the moon. Until this new study was published, however, scientists had found no evidence of Theia in the moon’s composition. Now, the study’s researchers believe the moon’s composition is roughly a 50/50 split between Earth and Theia.

Despite the news, some scientists remain skeptical. As noted by Reuters, it is generally believed that each body in space is home to a different chemical makeup or “fingerprint.” If that remains true today, then why are the differences between rocks on the moon and Earth so small?

“What you are looking for is a much bigger difference, because that is what the rest of the Solar System looks like based on meteorite measurements,” Professor Alex Halliday of Oxford University told BBC.

“It raises the question of how well the meteorites from Mars and the asteroid belt in the outer Solar System are representative of the inner Solar System? We do not have samples from Mercury or Venus,” he added.“They may well be similar to the Earth. If that is the case then all the arguments over the similarities of the Earth and the Moon fall away.”

If scientists do conclude that the differences are significant enough to justify the theory that Theia crashed into the Earth to form the moon, then it’s possible they will also have to rethink the idea that other planets and meteorites have very different fingerprints of their own.

Other scientists, such as Professor Rob de Meijer of Netherlands’ Groningen University, said the new research did nothing to alter his belief – that a buildup of nuclear fuel within the Earth caused an explosion in its crust and mantle, and that the moon was formed from this material. He said the only way to really discover the moon’s composition would be to return and explore rocks hidden further underground.

“The difference is too small,” he said to BBC. “We don’t know how the Moon was formed. What we need are manned missions to the Moon and a search for rocks deeper under the lunar surface, that have not been polluted by meteorite impacts and the solar wind.”

10 thoughts on “Moon formed after Earth collided with another world, study says

  1. This is crazy! If the Earth spins at just over 1000 miles per hour, and it collided with another planetary body, wouldn’t there be a flat spot on one side of Earth?

    Think!
    . . .

    1. Nope a big hole the Pacific Ocean. Also the Sumerian texts tell what body and the change in Earth’s Orbit and position in the Solar System. You can find in the first volume of the Earth Chronicles.

      The Sumerians told of a satellite (named King.GU) of a larger body struck Earth.

      1. Interesting. I thought the oceans were developed from the land masses gradually separating from one large land mass into separate continents.

        Still thinking . . . may have to look up King.GU.
        . . .

      2. Modern science is only now catching up with ancient knowledge. Library of Nineveh is only 9% explored. In ages past there was a very high technologically advanced civilization. The archeology suggests we are just scurrying around in its ruin.

        The original world that was struck by one of the satalites of a much larger body was called by the Sumerians Tiamat and was where the asteroid belt is now. Marduk was the “other body” and what hit Tiamat was called Nibiru. There was an exchange an of material and an orbital change just as you said. Mars may well have been one of Marduk’s satalites yanked out of orbit, some speculate. In any case Mars got pelted by some sizable asteroids at one point with may well have kill that world.

        Just google Nibiru, Better yet read Zechariah Sitchen’s books. Pretty interesting read. 12th Planet was the first. I’ve read most of them, but not all. Interesting stuff. May well explain the crazy stuff happening now and in the past.

        Doesn’t change anything what our eventual response to tyranny would be, but at least gives a clearer picture of what all and whom we are ultimately going to have to deal with. Hopefully for good this time around.

        1. I read the whole series including the book The Lost Book of Enki. I thought Tiamet was Earth before the hit. When it was in the orbit between Mars and Jupiter. King.GU was a small satellite and that is why Earth survived the hit. Anyway the books are great and explains a lot especially the biblical stories. Sheds a different light and are more informational.

  2. “Currently, the prevailing theory is that approximately 4.5 billion years ago, a planet called “Theia” collided with the Earth…”

    really? 4.5billion years ago a planet was called anything. I find this the hardest part to believe. Theia was named before anyone was around to name it? before anyone knew what a planet was?

    Perhaps they should have said
    Currently, the prevailing theory is that ‘approximately’ 4.5 billion years ago, a mythical/ hypothetical planet now called “Theia”(by some) may have collided with the Earth.

    1. You assume there was no one around to know that information but there were. The Annunaki were they gave the information to the Sumerians including a description of all the planets in our solar system the color whether it was a watery planet or gaseous, their moons and events that changed the system that they observed. In fact may books in the old testament are Sumerian texts with different names in some cases.

  3. And God said , Let there be lights in the firmament of the heaven to divide the day from the night; and let them be for signs, and for seasons, and for days, and years: 15 And let them be for lights in the firmament of the heaven to give light upon the earth: and it was so. 16 And God made two great lights; the greater light to rule the day, and the lesser light to rule the night: he made the stars also. 17 And God set them in the firmament of the heaven to give light upon the earth, 18 And to rule over the day and over the night, and to divide the light from the darkness: and God saw that it was good. 19 And the evening and the morning were the fourth day. Genesis 1:14-19
    They say 4.5 billion years, God says ‘in the beginning.” They speak theories, God speaks absolutes. We get to decide,what and who, we will believe.
