The study proposes two possible explanations.
One is that “the asteroid that formed this crater is still embedded in the Moon’s mantle” rather than sinking into its core after an impact some 4 billion years ago, James said.
The other is that the mass contains the remnants of the moon’s magma ocean, with the oxides concentrating there as it solidified when it cooled billions of years ago.
I call BS. This is a UFO full of hibernating aliens waiting for the right time to awaken to come and eat humans.
