Many of you high astronomers said that the formation of our Moon most probably happen when a Mars-sized collided with Earth,which is about 6000km,but our Moon is only about 3500km in size,where did the other half go?Our Moon should also contain some elements from Earth,so where did the other almost 4000km went?My theory is this:
It was heading towards the direction to the Sun due to its very strong gravity force,but Venus must have intercepted on the way with its gravity,forcing it to become a moon of hers,then after it forms,as it slowly went farther away from Venus,the Sun had more gravitional force on it and pulled it into an orbit a little eccentric,which may be now known as Mercury! If Messenger spacecraft has enough evidence to say that Mer

My theory:
Go look at the newest Mars pictures from the Rovers and the HIRES pictures from the Mars orbiter. Then go look at the southwest of the United States - four corners, Valley of the Gods, etc.
Notice any similarities?
I do.
My guess is that Mars was on the order of 9600km when it came exceedingly close in a 'glancing blow' - close enough for gravitational forces to 'break off' roughly 1/3 of Mars. The shattering gravitational impact sent larger chunks of the Martian landscape slamming into what is now the southwestern US. The lighter pieces were sent into an outward spiral, causing the majority of the asteroid belt. Slightly bigger chunks that did not fall to Earth make up the Moon. Mars and Earth were sent into wobbly orbits from the blast-back of the impact: since it was a deflective pass-by, the planets continued on in somewhat of the vectors they were on, but were 'pushed away' just enough to eventually fall into stable orbits around the sun.
Just my theory.

The EARTH has a radius of around 6500km,Mars has a radius of around 3,400km, so the numbers are actually about right...there is no "other half."

I'm seriously worried about the intellectual level of the people in the US when I see things like this...

See the source for pictures and a description of how it is theorized to have happened.
