Eddington, Ryle and Hoyle: How a major 20th-Century discovery was lost in confusion and noise Wall, Jasper


Webcast sponsored by the Irving K. Barber Learning Centre and hosted by the Physics and Astronomy Department. The Steady-State vs Big-Bang controversy of the 1960s, also known as the source-count controversy, was almost unparalleled in bitterness and rancour. The very personal struggle between Ryle and Hoyle changed the course of the lives of both men. It resulted essentially in the loss from the record of a major cosmological discovery which astronomers and cosmologists finally recognized and revisited far too late. Wall was directly involved in the fight and its resolution, and came to know both Ryle and Hoyle as friends. From this perspective he describes what happened, together with the flow of consequences into current astrophysics and cosmology.
