hubble-bubble

The proportionality constant , h , is known as the hubble constant and quantifies how fast space is stretching ? not just around us but around any observer in the universe 其中的比例常數h ,就是所謂的哈伯常數,它可以把空間向外延伸的快慢予以量化,不只針對我們周遭,也適用于宇宙中所有觀測者的周圍。

For the measured value of the hubble constant , this distance is about 14 billion light - years 由量測到的哈伯常數值來推斷,這個距離大約是140億光年遠。
