This was the first assumption to explain the origin of the moon. Back in the day
1898
Year. Joe, son of the famous biologist darwin
According to george darwin, "tide and similar effects in the solar system " , the moon is part of the earth
Then, because the earth turned too fast, it threw out some of the earth's matter, which formed the moon after it was removed from the earth
And the great pit left on earth is the pacific ocean now. This view soon received some opposition. They..
It is argued that at the rate of rotation of the earth, it is impossible to throw out something that size. Besides, if the moon is on earth
The material components of both should be consistent. But by "apollo,"

The ship from the moon
The rock samples brought up were analyzed and found to be very different。
The captive said
The assumption is that the moon would have been just an asteroid in the solar system, once, because it ran near the earth
He was captured by the gravity of the earth and never left it. There's another point that comes close to capture that says earth
It's been siphoning into its orbit for a long time, and more and more, and finally, months
Ball. But it was also pointed out that to a planet as big as the moon, the earth might not have the power to capture it。

The assumption is that both the earth and the moon are floating nebulas in the solar system, which rotate and accumulate, and form stars
Body. In the process of accumulation, the earth is faster than the moon, becoming “brother”. This hypothesis is also objectively present
The challenge. By adopting the "apolo"

The sample of the rocks brought back from the moon, people
Found the moon much older than earth. According to some, at least the age of the moon should

A billion years or so, and the age of the earth

Theoretically

Billion years ago, a planet bigger than mars, called thea, every hour

The speed of flight was so powerful that the iron core of the planet had hit us
The center of the earth. The result of the collision was a huge explosion, accompanied by
High temperature above 600°c. The earth was hit by an explosion
It's just a little bit of the heat
The steam, along with the other fragments, soared into outer space that later cooled down and condensed into dust
It's mixed up with other fragments that form a core, which then congregates, our neighbors

This is the new assumption of the cause of the moon in recent years。

Oh, shit. Call at johnson space center, houston
At the moon and planetary seminar, benz, slatry and harvard university, los alamos national laboratory, united states
Cameron of the astrophysics center of miz co-sponsored the big collision scenario. The assumption is that the solar system evolved early in the day
There have been large numbers of “stars” formed in interstellar space, which have grown up by collisions and accumulations. The stars merge into an original
