What theory says that the Moon broke off of the Earth?

the giant-impact theory
Finally, according to the fission scenario, Earth had been spinning so fast that some material broke away and began to orbit the planet. What is most widely accepted today is the giant-impact theory. It proposes that the Moon formed during a collision between the Earth and another small planet, about the size of Mars.

Why did Theia collide with Earth?

Originally Answered: Why did the planet Theia crash into Earth? Originally Answered: Why did the planet Theia crash into Earth? because orbits of Theia and earth intersected at a particular point and at one particular revolution around the sun, both of them were at that junction at the same time. Hence the collision.

What is the current theory on the origin of the Moon does it agree with the observed characteristic of the Earth and the Moon?

The giant-impact hypothesis is currently the favored scientific hypothesis for the formation of the Moon. Supporting evidence includes: Earth’s spin and the Moon’s orbit have similar orientations.

How long would it take for the Moon to fall to Earth?

If the moon suddenly stopped orbiting the earth it would start to fall due to gravitational attraction. The moon would contact the earth in about 4.6 days going very fast.

Was the moon split into two or more parts?

In 2010 NASA Lunar Science Institute (NLSI) staff scientist Brad Bailey said, “No current scientific evidence reports that the Moon was split into two (or more) parts and then reassembled at any point in the past.”.

What is the current theory on the origin of the Moon?

I’m not sure what you [re referring to, but the current theory is that the Moon is the result of a collision with early Earth and a Mars-sized planetessimal. Early on when the Earth was completely molten, the heavier elements (iron, etc.) were falling to the center of the Earth leaving behind a less-dense outer layer/crust.

How did the Moon reassemble itself?

When the collision happened, it ripped off that outer most layer and was flung out into orbit around Earth and eventually came together to form our Moon. This is the reassemble it, it is the result of two bodies collided with one another!

Did Muhammad point out the splitting of the Moon?

For theories of formation of the Moon which involve fragments, see Origin of the Moon § Accretion. Muhammad points out the splitting of the moon. Anonymous 16th-century watercolor from a Falnama, a Persian book of prophecy. Muhammad is the veiled figure on the right.
