100th ANNUAL PORTLAND TIME CONVENTION (or "The First of 100", depending on your perception - or direction - of time!)
Saturday, June 30, 2012, 1:30 p.m. – 10:00 p.m.
A celebration of time and its mysteries!
2:00 p.m. LECTURE: "Is time travel possible?" We discuss the science fiction concept of time travel, or "causality violation." Is it possible to jump ahead in the future or back in the past? We talk about Relativity; time dilation.
3:30 p.m. SHOW: "BLACK HOLES" The planetarium show about black holes. How do they form? How can we find them? How do they distort space-time?
4:00 p.m. LECTURE: STONE CIRCLES AND ANCIENT WORLDS A fascinating exploration of the stone circles around the British Isles and the engaging mythologies around them. Discover how the ancient people learned natural time cycles and how to track them.
