Thursday, 7/11, 7p
For adults & teens
Main Meeting Room (upstairs)

“How big is the Universe?”  “What is the Universe?” “Does the Universe have an age?”  The first decades of the 20th century saw a revolution in humanity’s understanding of our place in the world, with the Universe ‘growing’ from a small, Sun-centered Milky Way to billions of large galaxies like our own mysteriously rushing away from one another.  New telescopes were constantly yielding astonishing results that the scientific community rushed to keep pace with, as accepted theories were regularly overturned.  This program will talk about the people, telescopes, and events (such as the famous ‘Great Debate’ of 1920) that led to discoveries such as the true size and nature of galaxies, the existence of exploding stars, and the first evidence of the Big Bang.
