The interest in so-called dark energy and dark matter continues, but so do the doubts. Is it merely a modification of gravity? Is it the product of a new type of particle? The verdict is still out, though the dominant theory still seems to point toward a mysterious, invisible substance of some kind. The term “invisible” matter or energy seems to me to be the more appropriate one, but the term “dark” does grab the headlines. This video from Canada’s Perimeter Institute for Theoretical Physics in Waterloo, Ontario, hints at the ambiguities.
Fantasyland: Author Kurt Andersen
Above Video: Center for Inquiry / How can we make sense of America’s current “post-factual,” “post-truth,” “fake news” moment? By looking to America’s past. All the way back. To the wishful dreams and make-believe fears of the country’s first settlers, the madness of the Salem witch trials, the fantasies of Hollywood, the anything-goes 1960s, the gatekeeper-free internet, the profusion of reality TV….all the way up to and most especially including President Donald Trump. In this fascinating and lively talk, Kurt Andersen brings to life the deep research behind and profound implications of his groundbreaking, critically acclaimed and bestselling latest work.
