The Expanding Universe
Oct 26, 2016
Gresham College
Professor Joseph Silk FRS embarks on an illustrious journey through the universe to explain the paradigm shift in today's scientific view on the physical expansion of space http://www.gresham.ac.uk/lectures-and-events/the-expanding-universe
It was once inconceivable that the universe could be expanding. The static universe survived three thousand years of analysis and observation, to become enshrined as a cosmological solution to the equations of Einstein's theory of general relativity. Only after three decades into the twentieth century did a paradigm shift occur. This was based on observational data, but it was to take decades before the recession of the galaxies was accepted as the conceptual proof of the physical expansion of space. I will recount how the recession of the galaxies was first discovered and eventually accepted as a physical model for the expansion of the universe.
The transcript and downloadable versions of the lecture are available from the Gresham College website: http://www.gresham.ac.uk/lectures-and-events/the-expanding-universe
Gresham College has been giving free public lectures since 1597. This tradition continues today with all of our five or so public lectures a week being made available for free download from our website. There are currently over 2,000 lectures free to access or download from the website.
