哈勃的发现哈勃是20世纪美国著名天文学家,他利用天文设备观测,发现离地球很远的天体的光谱都有红移现象,因此他认为这些天体都在远离我们而去,由此他推测整个宇宙在不断地膨胀。哈勃常数根据自己的观测,哈勃得到一个结论:远处天体远离地球的速度和它们到地球之间的距离成正比,这个公式中还有一个哈勃常数,这个常数对于研究宇宙来说十分重要,因为从这个常数可以推导出宇宙的年龄。 Hubble’s discovery Hubble was a famous American astronomer in the 20th century. He used astronomical observations to find that the spectrum of celestial bodies far away from the earth had a red shift, so he thought that these objects were away from us. Presumably the entire universe is constantly expanding. Hubble constant According to his own observations, Hubble got a conclusion: The distance of distant objects from the Earth is proportional to their distance from the Earth. This formula also contains a Hubble constant, which is very much for studying the universe. It is important because the age of the universe can be derived from this constant.
