Finding shows the moon comes only from earth, not giant collision

Some astronomers have estimated that there may be twice as many Jupiter-sized rogue planets as there are stars.

While a recent study has speculated that there may be one hundred thousand times more rogue planets than stars.

thats a lot of planets going every random direction. you want to tell me it's not possible that one of those things either hit earth directly or just grazed the earth and took a good 1/4 chunk off which got caught in new earth's gravitational pull.

Let me introduce you to the Roche Limit

The Roche limit ( /ˈroʊʃ/), sometimes referred to as the Roche radius, is the distance within which a celestial body, held together only by its own gravity, will disintegrate due to a second celestial body's tidal forces exceeding the first body's gravitational self-attraction.[1] Inside the Roche limit, orbiting material will tend to disperse and form rings, while outside the limit, material will tend to coalesce. The term is named after Édouard Roche, the French astronomer who first calculated this theoretical limit in 1848.[2]

So if rogue planet were to do that, then it would still need to be Mars size or smaller. If it had been bigger, it would have shattered the Earth.

So we can't say that a rogue planet from outside our solar system did not hit us as you suggest, but it just makes more sense for it it be a planet that formed here, as current planet formation theories and computer models suggest that there were many, small rocky bodies that formed, but not all had stable orbits (hence rogue planets too, heh). Some were flung out, some fell into the sun, and others, hit other planets.

If we are to follow this new premise that the moon originated from earth, then how bout the following method?

The eruption of a supervolcano spewing Lava so high it exists orbit and as it cools it solidifies into the moon.

The moon is really just too big for something on that scale to have happened and the Earth's gravity is just too strong for that much stuff to eject via a volcanic process to put so much material into orbit. The forces needed to put that much stuff into orbit are just too great.

Would kind of help explain why the moon doesnt rotate? because it was "made" from within earth, so whilst the supervolcano was erupting spewing lava into space, the material was conforming into a ball.

The moon doesn't rotate because it is tidally locked. That happens often when a smaller body orbits close enough to a larger body. Mars is tidally locked with the Sun. Phobos and Deimos are tidally locked with Mars. Pluto and Charon are tidally locked to each other because they are relatively close to each other in size.

Pssssst. LifeInDeath........Mars rotates and has a day / night cycle of 24.622 hours:

In theory, sure. But it's far more likely that whatever might have hit Earth I was created out of the same proto-planetary disc as the rest of the solar system. The theorized history of the early solar system involves literally hundreds of planets and dwarf planets that formed out of ever colliding dust and asteroids. Eventually, all of these planets coalesced into the eight we have today. The theorized Theia/Earth I collision would have been among the very last of these, probably. Planets like Jupiter and Saturn probably swallowed up all sorts of more minor worlds as the solar system was developing. We think that an Earth-sized world probably smacked into Uranus at some point, explaining why the whole planet is tipped on its side.

In the model where Theia hits the Earth forming the Moon, the world would have been orbiting the Sun at almost the same orbit as the Earth. It might have even formed in the same orbit, perhaps at a Lagrange point, but something changed either its or the Earths orbital rate (probably another major planetary strike) and so eventually one world caught up with the other and they smashed.

Yeah, maybe far fetched but isnt every theory these days?

Would kind of help explain why the moon doesnt rotate? because it was "made" from within earth, so whilst the supervolcano was erupting spewing lava into space, the material was conforming into a ball.

As the volcano was dying down, the thin "geyser" of lava dies down and detached from the in orbit moon like an umbilical chord.

Does that mean the moon also has oil?

No oil I'm afraid as crud oil is made from organic compounds. And the moon has never had life as far as we know.


Unless the movie "Apollo 18" is true........rocks with legs....brrrrrrrrrr!

That's actually becoming a debunked theory as well. New scientific evidence proposes oil is created deep within the earth where magma or heat is present.

The moon does rotate it just rotates in tandem with its orbit around earth from our point of view it looks like the moon is always facing us from the same side but in space it is rotating...

They're seriously saying the moon came from Earth rather than is made of the same stuff as Earth! Sounds rather un-scientific to me...

Perhaps the next thing will be science touting credence in the Sumerian creation myth regarding Tiamat, the Earth and Niburu... (yeah, I just went there )
The Enuma Elish

Although I find Sitchin's translation much more entertaining...
The Late Great Planet Tiamat

The planet "Marduk" (the Sumerian "Nibiru"), as it came into the solar system on its 3,600-year clockwise (retrograde) elliptical course, struck Tiamat, which was moving in its ordained counterclockwise orbit. According to Sitchin’s well-known translations, one of Marduk’s satellites struck Tiamat first, followed by two more of Marduk’s moons. Then Marduk itself, an enormous cosmic entity, struck Tiamat, smashing one half of the planet into pieces, which became what the Sumerians called the Great Band. The remaining half of the planet, which was struck by a smaller moon of Marduk, was catapulted into a new orbit, along with a chunk of material which became its moon. According to the Enuma elish, Tiamat’s original moons were dispersed, many changing the direction of their orbits and rotations. There is indeed evidence of this great cataclysm in our solar system today.

Truth or fiction? One day we may find out ... I hope

~edit~
Almost forgot: There is always that rather large hole in the Pacific ocean to consider...

Isn't the Scientist's " Theia " mentioned in the Terra Papers..

So now we have multiple sources talking of a planet that used to be but is no longer...

could the moon be the remains of that planet ? And it's attraction to earth is because of them colliding creating a magnetization of each other.

^ makes sense ? yes ? no ?

I'll repeat something that I offered in a thread a few weeks ago. The material of the Moon came from the low areas that now make up our oceans. There is no way that the continents could have "separated" to such an extent as claimed unless the earth is expanding in size like an inflated balloon. It didn't and isn't.

Earth, was literally terra-formed to have these magnificent oceans and seas and the creation of the Moon--which is entirely unnatural for its size in relationship to the earth--was the result. In short, earth didn't need a Moon, but it got one because it needed the oceans. And Whence came life.

If you can't allow that aliens did the deed, then fall back on the religious beliefs that God did it.

What a lot of nonsense we have continents because of tectonic plates...

We have tectonic plates because our planet has a molten core and is constantly shifting...

Earth is getting bigger all the time because of all the dust and meteorites that earth's gravity collects...

We dont have low points in the ocean we have high points outside the ocean caused by volcanic eruption that has cooled also mountains are formed when plates collide and push rock upwards.

Do they know what is under the surface of the moon? Are there instruments capable of that? Otherwise they are basing their findings on what was scraped off the very top surface and brought back (disregarding any 'fake moon landing' conspiracy).

Like guessing what kind of cake it is by scraping off a bit of frosting.

This vid answers many of the questions asked in this thread.



I love the animation. Makes logical sense.

Heard of elemental isotopes? For instance hydrogen has 7 isotopes. Hydrogen is the only element that has different names for its isotopes in common use today. The 2H (or H-2) isotope is usually called deuterium, while the 3H (or H-3) isotope is usually called tritium. The ordinary isotope of hydrogen, with no neutrons, is sometimes called "protium".

You may also be familiar with a common 'mutation' of water, H2O2, or hydrogen peroxide.

If you paid attention in science class lol I'm sure you would of learned long time ago that the moon is part of the earth.

Hate to be CAPTAIN OBVIOUS here.. but after sampling the moon rocks and earth rocks and finding out they are exactly similar, Didn't anyone ever think that we NEVER went to the moon? That those 'moon' rocks are actually 'earth' rocks. Logical conclusion, eh?

If a collision occurred.... why would taking surface rocks help determined the the moons make up? If it collided with the earth long ago, and some of that material redeposited on the moons surface, wouldn't it seem to have a similar comp to earth? IMO, to analyze the moon properly, a sample of its insides would lead to a more accurate conclusion as to its make up. Not deep inside of it but deeper than the surface.

Considering the moon is older than earth, that is not the answer.
