这篇文章的中文翻译是什么?（请英文高手来翻译,谢谢!）
This new theory builds on the idea that around four billion years ago the Earth was struck by a Mars-like planet, but instead of the smash producing enough debris for one moon, this paper argues there was enough for two.
This small second moon become stuck in a gravitational tug of war between the Earth and its much larger sibling. After millions of years in this position the new moon was drawn into a collision at a speed of less than three kilometres per second.
The scientists say this slow paced crash may have caused a build up of material and the formation of highlands on the Moon's far side.
For decades scientists have been trying to understand why the visible near side of the Moon is covered in craters while the far side has mountain ranges higher than 3,000 metres.
The researchers hope that Nasa observational missions might prove this new theory within a year

答案

这一新理论的基础上的想法,大约四十亿年前,地球遭受类似火星的行星,但不是粉碎产生足够的碎片,一个月亮,本文认为有足够的2.
这个小月亮成为停留在引力战争之间的地球和它大得多的兄弟姐妹.经过几百万年在这个位置上的新月,被卷入在碰撞速度小于每秒三公里的速度.
科学家说这种慢节奏的碰撞可能造成构建了材料和形成的高地,在月球的远.
几十年来,科学家一直试图理解为什么可见月亮近侧覆盖在陨石坑而远侧有山峰高于3000米.
研究人员希望美国宇航局观测任务可能证明这一新的理论在一年
（不知道真不正确.）
