"How Old Is It?" at Fordingbridge Astro, 17 Feb,

[BinocularSky]

(by yours truly...)

Aristotle thought it was eternal; James Ussher dated its creation to 6pm on 22 Oct 4004 BCE; Newton eventually decided that it was infinite, static, and eternal; by 1958 it seemed to be younger than the oldest stars; by 2013, this had all been resolved and we now accept the Universe to be approximately 13.8 billion years old. This talk traces the ideas, evidence and reasoning for the answers to this most fundamental of questions.
