  • $\begingroup$ @barrycarter Luminosity is inversely proportional to the distance squared. I was wondering how people would use that equation to calculate the distance to distant galaxies. They take the intrinsic luminosity of various stars within the galaxy to find the distance. But I wonder how.... $\endgroup$ – Pedro de Oliveira Jun 28 '19 at 4:16
