Just a few weeks after Planet 9 details surfaced online, scientists throw out another discovery to the world that is guaranteed to make your head explode. After studying Moon rocks brought back by astronauts on the Apollo missions, scientists at the University of California dropped a scientific bombshell: Earth is actually two planets that came together during a head-on collision.
According to their research, the collision was so violent that it formed the moon. According to Telegraph, scientists found that the oxygen isotopes of the moon rocks are the same as those on Earth.
It means that the collision between Their and the early Earth was so violent that the two planets effectively melded together to form a new planet, a chunk of which was knocked off to form the Moon.
“We don’t see any difference between the Earth’s and the Moon’s oxygen isotopes; they’re indistinguishable,” said Edward Young, lead author of the new study and a UCLA professor of geochemistry and cosmochemistry.
“Theia was thoroughly mixed into both the Earth and the Moon, and evenly dispersed between them. This explains why we don’t see a different signature of Theia in the Moon versus the Earth.”
Scientists approximate that the crash with Theia happened roughly 100 million years after the Earth formed, making that almost 4.5 billion years ago.
That is insane. What’s next – aliens? God, we really hope it’s aliens.
