We have a mystery right here in River City. I say “River City” because it is right next door. The astronomers are baffled. The problem is all the theories in the world about how the Moon came to be are running foul of the facts. It is becoming increasingly apparent that the Moon has an identical chemical composition to the Earth. We could get into defining that like the water is the same, the titanium is exactly the same. So that pretty much throws a lot of cold water on the existing favorite theory of a Mars sized body hitting the Earth in our past and creating the Moon. Scientists go for something called Isotopes which are like chemical fingerprints. Well to the astronomer's dismay, the fingerprints are identical. At some point in our past, the Earth and the Moon were probably one body.
Chemistry is not my field. Never even took it in high school. But the point is the Moon is a smaller version of Earth. I suggest at one point it might have even had an atmosphere. If it was the result of a collision then the Moon would have traces of the collision all over it. There is little if any evidence that the Moon was the result of a collision. I suggest they are from a much larger planet that broke up.
The related mystery is water. Where did all the water on this relatively small planet Earth come from? No one knows. It is a lot more water than we are entitled to have under natural laws of planetary evolution. It too is a mystery that astronomers and geologists are struggling to find an answer to.
The evidence also points to the Moon being a separate planet at one time. I am guessing here, with a lot more water than exists on the Moon today. In other words, it was a planet with oceans.
If both Earth and the Moon were water planets, then what happened to the Moon's oceans? No one knows. Guessing, the Moon has a 28-day rotation facing the Earth at all times. That means the same side of the moon faces the Earth no matter where it is in its orbit around the Earth. Two weeks of that rotation are spent at temperatures of 220 or more degrees Fahrenheit. The dark side of the moon is at an equally intense 200-400 degrees below zero. Most of the water would have escaped the relatively low gravity of the moon as it froze and vaporized over and over again. Where would the vapor go? I suggest it came here to the Earth. It then added to the oceans on Earth. Chemistry and physics laws would make this happen over a long period of time. It didn't happen all at once.
If that guess is right, then the Moon has oceans as well. They are in an artery system way below the surface of the moon. Probably with a valid atmosphere buried deep in the moon. The moon could actually be partially hollow inside. The water would have excavated mammoth type caves all over the interior of the Moon. (Guesses are no good unless they predict things that might be. That is my prediction. The Moon has an elaborate cave system deep under the surface.)
I think it is possible that both the Moon and the Earth came from a much larger Planet somewhere in the solar system. The planet exploded for some reason.
To explode you need an explosive. Or you need gravitational pulls that unstabilize the planet. That could only happen if a Jupiter-sized or better body came near to this planet. I am again guessing. So either Saturn or Jupiter or both might have been involved in the birth of the planet Earth. Saturn is not quite large enough. But I think it is the villain here anyway. Keeping it simple, let us say it was Saturn. Only because Saturn to this day has moons covered in a nitrogen atmosphere. Titan comes to mind.
I am thinking it might have been a combination of both Jupiter and Saturn. The planet was probably one in from Jupiter.
The asteroid belt also has a fingerprint similar to the Earth. The asteroids are in a necklace arrangement on one side of the Sun. They orbit together almost like a planet was destroyed there.
I am suggesting that planet was a hot core planet with huge oceans on it. The hot core kept the oceans liquid. It had a relatively thin upper crust shielding it from the explosive results of water coming into contact with the hot liquid core. I think it was similar to but smaller than Uranus or Neptune. My guess is that Earth, Moon, Mars, Mercury, and the asteroid belt all have a common origin. The jury is still out on Venus as I think that came to its present orbit much later.
Mercury has a gravitational pull almost equal to the Earth. That suggests heavy metal core material. The Moon and Mars are much lighter. Though when our astronauts visited the Moon, the gravity was higher than expected.
What I think happened is an outside source of gravity destabilized the planet. It came in contact with the huge oceans and the core as the crust was destroyed by gravity. The oceans blew the planet apart in a tremendous explosion. This divided the planet into 4 or even more large planetary bodies. I think those bodies scattered throughout the solar system. The larger ones became the Earth, the Moon, Mercury, and Mars. A small remnant became our asteroid belt. The rest formed orbits around the major four giants. Those are Neptune, Uranus, Saturn, and Jupiter.
Two of those bodies reformed into planets that we now know as the Earth and the Moon. I am guestimating this occurred around 4 billion years ago.
