344:, mulling over the Paradox and its rich history. This book clarified that the lack of energy is not primarily because the universe is expanding, but rather because the stars and galaxies have had only about 15 billion years to radiate, and do not have sufficient energy to keep radiating for much longer. 44: 340:(the night sky is dark despite the vast number of stars in the universe). In 1964, he published detailed calculations that solved the paradox by concluding that stars do not generate enough energy to illuminate the entire sky. In 1987, he published a book, 285:. He also played a key role in the rise to international prominence of the Five College graduate course in astronomy. At his death, he was emeritus Distinguished University Professor of Physics and Astronomy at UMass, and an adjunct professor at the 332:
