测量结果惊人的准确，他测出了万有引力恒量的参数，在此基础上卡文迪许计算地球的密度和质量。
The result was a remarkably accurate estimate of a parameter called the gravitational constant, and from that Cavendish was able to calculate the density and mass of the earth.
长期以来，这种密度上的相似性促使人们猜测月球是从快速旋转的地球上分裂出来的，但这种想法创始于两次观测。
This similarity in density has long prompted speculation that the Moon split away from a rapidly rotating Earth, but this idea founders on two observations.
在我们的太阳附近，星际物质的平均密度比最好的地球实验室真空还要低1000到10000倍。
The average density of interstellar material in the vicinity of our Sun is 1,000 to 10,000 times less than the best terrestrial laboratory vacuum.
