身为地球母亲的孩子,人类在过去的很多年,竟然不知道自己的老妈多少岁。真够糊涂的。为了搞清地球的年龄,几百年来,科学家们绞尽脑汁、观天探地,奇葩手段无所不用其极,终于算出地球的真实年龄为——抱歉,不小心按了128倍快进,差点儿剧透了结局。让我们倒回开头,来到18世纪,从一个名叫布丰的科学家和他的“红烧铁球”说起。红烧铁球18世纪时,人们已经知道,地球的内部是滚烫的岩浆,地表则不凉也不烫。于是,科学家们猜测,地球就像煮熟的鸡蛋,本来里外一样烫,随着时间的推移,外面的蛋白(地壳)先变凉,然后才轮到蛋黄(地心)。
As a child of Earth Mother, mankind did not know how old his mom was for many years in the past. Enough confused. In order to find out the age of the earth, for hundreds of years, scientists have racked their brains, observing the sky and exploring the earth. The wonderful means have been used everywhere. Finally, the real age of the earth is calculated as - Sorry, accidentally pressed 128 times fast forward Almost done through the ending. Let’s rewind back to the eighteenth century, starting with a scientist named Buffon and his “Braised Iron Ball.” Braised iron ball 18th century, people already know that the Earth’s interior is hot magma, the surface is not cold nor hot. As a result, scientists speculated that the Earth was like a boiled egg, which had been hot inside and out. Over time, the outer protein (the crust) cooled down before it reached the egg yolk (center of the earth).
