In 1783, amateur astronomer William Herschel attempted to determine the shape of the universe by examining stars through his handmade telescopes. Herschel was the first to propose a model of the universe based on observation and measurement. At that time, the dominant assumption in cosmology was that the Milky Way was the entire universe, an assumption that has since been proven …
