“…Carver, whose excellent new book also considers topics ranging from evolutionary theory to the prospect of life on other planets, views nineteenth-century alternate histories as "a means to reflect on how scientific, cultural, and historical discoveries altered the understanding of the past." 4 Future work in Victorian studies will no doubt explore traces of the uchronian imagination in a wide variety of modes and genres. The scientific romance, certainly: Genie Babb, for instance, has classified H. G. Wells's The Time Machine, The Sleeper Awakes, and In the Days of the Comet (along with William Morris's News from Nowhere) as "future uchronias," while describing A Modern Utopia, with its conceit of a parallel Earth, as a blend of the "alternate history" and "parallel worlds" tropes.…”
