Scientists Say The Earth Is Actually Two Planets
Scientists have concluded that Earth is actually made up from two planets which came together in a head-on collision that was so powerful it formed the Moon. Initially scientists believed that the Moon was created when a smaller planet called Theia grazed the Earth and broke it up, sending a small piece of it hurling into space where it caught in Earth’s gravity. However, scientists have now discovered after studying Moon rocks that their oxygen isotapes are the same as on Earth.
