May's meet-up will be on a Wednesday.

We'll start by attending a one hour public show at the W. J. McCallion Planetarium, and then we'll relocate to the nearby Phoenix Bar & Grill for a drink and some food.

Planetarium tickets are $5/person, cash only at the door. SPACE IN THE PLANETARIUM IS LIMITED, so reserve your spot online asap:

IMPORTANT NOTE: It appears that the tickets are sold out for the planetarium. As there are usually a lot of no-shows, I recommend that people still show up at the planetarium at 7PM. If there isn't space, those who don't get in can head over to the Phoenix one hour early.

The Show: Light Years
We've all heard that nothing can go faster than the speed of light, that the Sun is 150 million kilometres from Earth, and the universe is 14 billion years old. The majority of us may not have heard of how these values were determined. What stopwatch do we used to measure the age of the universe, let alone the age of the Earth? What radar gun can we use to catch how fast light travels? And where do we store a 150 million kilometre measuring tape? This show will answer all of these questions, and more, regarding the nature of how distance, time, and speeds are measured in the universe.
