In recent decades the scientific consensus has been that the moon formed billions of years ago from debris cast off when a Mars-sized object dealt Earth a glancing blow. But a radical new theory holds that some long-ago giant collision actually disintegrated Earth, causing it to balloon out into a vast doughnut-shaped cloud of vaporized rock, which the scientists who developed the theory dubbed a synestia." They say the moon subsequently formed within this cosmic maelstrom.
In the long-accepted explanation of lunar formation, the collision between Earth and the Mars-sized object, known as Theia, ejected part of Earth's mantle essentially molten rock and metal and left debris orbiting our planet. Over time, the bits of debris collided and clumped together to form the moon.
But when the researchers used powerful computers to simulate this process, they ran into the same problem that has long vexed scientists examining the Theia theory: It was hard to see how the collision and the ensuing clumping of debris could explain the moons unique chemistry, said study co-author Dr. Sarah Stewart, a professor of Earth and Planetary Sciences at the University of California, Davis.

The movie “Strange Brew” comes to mind. “Do you want a jelly?”
228 years of the kids asking, Are we there yet?.
Maybe they were reading Terry Pratchet novels?
“I’ll turn this around and we can just go back home!”
And then you get there and the moose out front tells you Mars is closed. :(
I didn’t see anything about elephants and turtles.
(But then I didn’t read the whole thing, and I haven’t talked to Rincewind for a long time either.)
The biggest thing is the tides. The tides help to keep the waters near the coast clean and oxygenated.
It is also amazing to think a car could get to the moon faster than a wagon train could trek across America.
The donut is the scientist’s head.
That’s why they always say don’t write your theory before lunch.
“A car could get to the moon faster than a wagon trek across America ...”
Umm, I remain skeptical of this claim, what exit do you take from the I-5, Mukilteo?
>...how far away these planets are...
I found this a year or so ago. The moon is 1 pixel and the solar system is drawn to scale based on it. Be prepared to spend some time scrolling.

On a scale where one foot equaled a million miles, the earth would be a small pea, the sun would be a small pumpkin in my neighbors yard. The nearest star would be around 4,300 miles away.
Strange Moon Facts
Compiled by Ronald Regehr (astronautical/aeronautical engineer)
“The Moon is the Rosetta stone of the planets.” Robert Jastrow, First Chairman, NASA Lunar Exploration Committee
After hundreds of years of detailed observation and study, our closest companion in the vast universe, Earths Moon, remains an enigma. Six Moon landings and hundreds of experiments have resulted in more questions being asked than answered.
1. Moons Age
The Moon is far older than previously expected. Maybe even older than the Earth or the Sun. The oldest age for the Earth is estimated to be 4.6 billion years old; Moon rocks were dated at 5.3 billion years old, and the dust upon which they were resting was at least another billion years older. Or the moon is at a minium 6.3 Billion years old.
2. Rocks Origin
The chemical composition of the dust upon which the rocks sat differed remarkably from the rocks themselves, contrary to accepted theories that the dust resulted from weathering and breakup of the rocks themselves. The rocks had to have come from somewhere else.
3. Heavier Elements on Surface
Normal planetary composition results in heavier elements in the core and lighter materials at the surface; not so with the Moon.
According to Don Wilson, “The abundance of refractory elements like titanium in the surface areas is so pronounced that several geologists proposed the refractory compounds were brought to the Moons surface in great quantity in some unknown way. They don’t know how, but that it was done cannot be questioned.”
4. Water Vapor
On March 7, 1971, lunar instruments placed by the astronauts recorded a vapor cloud of water passing across the surface of the Moon. The cloud lasted 14 hours and covered an area of about 100 square miles.
5. Magnetic Rocks
Moon rocks were magnetized. This is odd because there is no magnetic field on the Moon itself. This could not have originated from a “close call” with Earth as such an encounter would have ripped the Moon apart.
6. No Volcanoes
Some of the Moons craters originated internally, yet there is no indication that the Moon was ever hot enough to produce volcanic eruptions.
7. Moon Mascons
Mascons, which are large, dense, circular masses lying twenty to forty miles beneath the centers of the Moons maria, “are broad, disk-shaped objects that could be possibly some kind of artificial construction. For huge circular disks are not likely to be beneath each huge maria, centered like bulls eyes in the middle of each, by coincidence or accident.”
8. Seismic Activity
Hundreds of “Moonquakes” are recorded each year that cannot be attributed to meteor strikes. In November, 1958, Soviet astronomer Nikolay A. Kozyrev of the Crimean Astrophysical Observatory photographed a gaseous eruption of the Moon near the crater Alphonsus. He also detected a reddish glow that lasted for about an hour.
In 1963, astronomers at the Lowell Observatory also saw reddish glows on the crests of ridges in the Aristarchus region. These observations have proved to be precisely identical and periodical, repeating themselves as the Moon moves closer to the Earth. These are probably not natural phenomena.
9. Hollow Moon
The Moons mean density is 3.34 gm/cm3 (3.34 times an equal volume of water) whereas the Earths is 5.5. What does this mean? In 1962, NASA scientist Dr. Gordon MacDonald stated, “If the astronomical data are reduced, it is found that the data require that the interior of the Moon is more like a hollow than a homogeneous sphere.”
Nobel chemist Dr. Harold Urey suggested the Moons reduced density is because of large areas inside the Moon where is “simply a cavity.”
MITs Dr. Sean C. Solomon wrote, “the Lunar Orbiter experiments vastly improved our knowledge of the Moons gravitational field ... indicating the frightening possibility that the Moon might be hollow.”
In Carl Sagans treatise, Intelligent Life in the Universe, the famous astronomer stated, “A natural satellite cannot be a hollow object. Therefore, the Moon may not be a natural satellite at all”
The Zulu believe the moon is hollow and home of a reptilian race (The Water Brothers) who brought the moon here. Arrival ended the Golden Age. Moon believed to be space ship of reptilians
The model explains all the oddities of the moon. More importantly, there is no data the contradicts this theory.
10. Moon Echoes
On November 20, 1969, the Apollo 12 crew jettisoned the lunar module ascent stage causing it to crash onto the Moon. The LMs impact (about 40 miles from the Apollo 12 landing site) created an artificial Moonquake with startling characteristics the Moon reverberated like a bell for more than an hour. Seismographs all in one general area on Earth side & switched off in 1977.
This phenomenon was repeated with Apollo 13 (intentionally commanding the third stage to impact the Moon), with even more startling results. Seismic instruments recorded that the reverberations lasted for three hours and twenty minutes and traveled to a depth of twenty-five miles, leading to the conclusion that the Moon has an unusually light or even no core.
11. Unusual Metals
The Moons crust is much harder than presumed. Remember the extreme difficulty the astronauts encountered when they tried to drill into the maria? Surprise! The maria is composed primarily illeminite, a mineral containing large amounts of titanium, the same metal used to fabricate the hulls of deep-diving submarines and the skin of the SR-71 “Blackbird”. Uranium 236 and neptunium 237 (elements not found in nature on Earth) were discovered in lunar rocks, as were rustproof iron particles. The moon is comprised of three layers with the densest on the surface.
12. Moons Origin
Before the astronauts Moon rocks conclusively disproved the theory, the Moon was believed to have originated when a chunk of Earth broke off eons ago (who knows from where?). Another theory was that the Moon was created from leftover “space dust” remaining after the Earth was created. Analysis of the composition of Moon rocks disproved this theory also. Another popular theory is that the Moon was somehow “captured” by the Earths gravitational attraction.
But no evidence exists to support this theory. Isaac Asimov, stated, “Its too big to have been captured by the Earth. The chances of such a capture having been effected and the Moon then having taken up nearly circular orbit around our Earth are too small to make such an eventuality credible.”
13. Weird Orbit
Our Moon is the only Moon in the solar system that has a stationary, near-perfect circular orbit. Stranger still, the Moons center of mass is about 6000 feet closer to the Earth than its geometric center (which should cause wobbling), but the Moons bulge is on the far side of the Moon, away from the Earth. “Something” had to put the Moon in orbit with its precise altitude, course, and speed. Coincidence of all these happening randomly puts the odds at zero.
14. Moon Diameter
How does one explain the “coincidence” that the Moon is just the right distance, coupled with just the right diameter, to completely cover the sun during an eclipse? Again, Isaac Asimov responds, “There is no astronomical reason why the Moon and the sun should fit so well. It is the sheerest of coincidences, and only the Earth among all the planets is blessed in this fashion.”
15. Ages of Flashes
Aristarchus, Plato, Eratosthenes, Biela, Rabbi Levi, and Posidonius all reported anomalous lights on the Moon. NASA, one year before the first lunar landing, reported 570+ lights and flashes were observed on the Moon from 1540 to 1967. 2014 sightings.
16. Operation Moon Blink
NASAs Operation Moon Blink detected 28 lunar events in a relatively short period of time.
17. Lunar Bridge
On July 29, 1953, John J. ONeill observed a 12-mile-long bridge straddling the crater Mare Crisium. In August, British astronomer Dr. H.P. Wilkens verified its presence, “It looks artificial. Its almost incredible that such a thing could have been formed in the first instance, or if it was formed, could have lasted during the ages in which the Moon has been in existence.
18. The Shard
The Shard, an obelisk-shaped object that towers 1.5 miles from the Ukert area of the Moons surface, was discovered by Orbiter 3 in 1968. Dr. Bruce Cornet, who studied the amazing photographs, stated, “No known natural process can explain such a structure.”
19. The Tower
One of the most curious features ever photographed on the Lunar surface (Lunar Orbiter photograph III-84M) is an amazing spire that rises more than 5 miles from the Sinus Medii region of the lunar surface.

20. The Obelisks
Lunar Orbiter II took several photographs in November 1966 that showed several obelisks, one of which was more than 150 feet tall. “... the spires were arranged in precisely the same was as the apices of the three great pyramids.”
21 No Moon
Tiahuanaco Bolivia calendar mentions there was a time of no moon. Prosolines (mentioned by numerous Greek and Roman authors) lived in Arcaidia and claimed the area because their ancestors had lived there before there was a moon. According to the calendar the moon entered into its present orbit between 11500-13000 years ago: 8500-11000 BC or the end of the Great Ice Age.
Likely bubbles, rather than strictly "hollow".
The moon gives us the tides...
Regular tides improved the chances of Life forming on Earth.
it protects us from space rocks
Along with Jupiter's massive space presence, even more reason for Life to be sustained on Earth.
(And less reason for Life to appear elsewhere in The Cosmos).
