Reconceiving the Universe, Again

In the 1920s, the scale of the universe changed dramatically with the discovery of thousands of galaxies beyond our Milky Way and the expansion of the universe. By 1963, the expanding universe was explained with a "big bang," and by 1980, an explanation of the big bang led to the proposal that the universe was unimaginably more vast than anything we could detect.
