Astronomical Distance Ladder

Paper Summary:

This paper focuses on the issues surrounding the discovery and refinement of the astronomical distance ladder, beginning with a brief account and definition of the ladder itself before moving onto a definition and discussion of the insights of Edwin Hubble. After considering Hubble's contributions, it then discusses the developments offered by new scientists attempting to pin down the Hubble Constant in their work. The astronomical distance ladder is a device used by astronomers to measure distances between objects in space. The basic premise of the ladder is that, since we cannot measure distances directly, we make our distance observations based on distances that are already known.

From the Paper:

"As regards the Astronomical Distance Ladder, this was a huge and important step in the direction of the debate. Previous understandings of distance were based largely on the intensity of objects, and the nineteenth century standard generally held to the idea that "faintness means farness," but the Hubble constant and its revelation of a constantly expanding Universe opened the door to a wide variety of debates about the way distances are measured (Gingerich 1071). Indeed, then the current debate has largely settled around more specific elements of Hubbles view, rather than a whole-scale rejection of his system or some other form of innovation. Indeed, the large and greater portion of debates relating to the astronomical distance ladder focus "on recently determined and still controversial values of the Hubble constant." "
