没有月球，地球也将不一样。
Earth just wouldn’t be the same without the moon.

非常正确，因为没有月球，地球将会摇晃，气候也将随之改变。点击我的气候变化链接，看看它是怎么回事。
Very true, because without the moon, the earth would wobble and climate would change to make up for it. Click on the climate change link in my note to see how that might work.

我们碰巧有这个月球。这个大巧合是：到目前为止，最合理的推测是火星大小的小行星撞击地球，地球喷出熔融物质，成为了月球。听一听:我正在读这篇文章:
But we got the moon by accident. Big accident: best guess so far is that Mars-sized asteroid hit earth and earth spit out molten material that became Moon Listen: I am reading this:

"在1969年至1972年期间，6次载人和3次自动任务回收了382公斤(约84磅)月球岩石和沉积物。月球上的物质表明，月球的成分与地球相似，但没有地球岩石那么高的铁含量。样本的年龄表明，月球大约在44.8亿年前形成，就在大约45.6亿年前地球形成之后。
"Between 1969 and 1972, six manned and three automated missions recovered 382 kilograms (or about 84 pounds) of lunar rocks and sediment. The lunar materials showed that the Moon was similar in composition to Earth, but lacked the high iron content characteristic of Earth's rocks. The age of the samples suggested that the Moon formed about 4.48 billion years ago, just after Earth's formation approximately 4.56 billion years ago.

月球样本中最令人惊讶的重要发现之一是一种被称为斜长岩的高浓度火成岩。这种岩石是在特定的压力和温度下由岩浆形成的。月球表面覆盖着斜长岩的事实表明，月球曾经被岩浆海洋所覆盖。如果是这样，月球一定是在非常高的温度下形成的。再加上其它证据，天体物理学家们得出了现今最广为接受的假说:在地球历史的早期，它被一颗火星大小的小行星撞击，并抛出了脱落的熔岩，形成了月球。
One of the most surprising and important discoveries in the lunar samples was the high concentration of an igneous rock called anorthosite. This type of rock forms from magma at particular pressures and temperatures. The fact that the lunar surface is literally covered with anorthosite suggests that the Moon was once covered by oceans of molten magma. If so, the Moon must have formed at very high temperatures. Together with other evidence, this has led astrophysicists to the most widely accepted hypothesis today: Early in its history, Earth was struck by a Mars-sized asteroid and ejected molten material that ultimately became the Moon.
