This relation, which was formulated by analyzing the spectra of galaxies, is currently believed to be caused by dark energy and is a variation of Doppler shift in the context of special relativity.

Fainter, older galaxies were noted to have their spectrum shifted further to lower wavelengths, a result which supported the predictions of the Friedmann equations and indicated that other galaxies were moving away from our  galaxy. A more interesting observation showed that not only were galaxies in all regions of the sky moving away from the Milky Way, but they were also moving away from each other. FTP, what is this law which  explains the expansion of the universe which gets its name from its famous astronomer formulator and a  namesake constant and space telescope?
