The club is hosting Professor Shane Larson from Northwestern University in Chicago for the August 9th Meeting at the “Party Palace” located at 8616 N Lehman Road, just north of Bigelow Gulch Road. Pot luck before the meeting starts about 6:30 pm, presentation scheduled for 7:30 pm.

The Cosmos abounds with matter that emits copious amounts of light, both in the spectrum of visible colors we perceive with our eyes as well as in invisible light such as x-rays and radio waves. But in the latter half of the 20th Century we discovered that a significant part of the Universe is filled with matter that doesn’t emit ANY light at all. In the last two decades, we have discovered an even more mysterious material that appears to be driving changes in the scale of the Universe. These dark influences are known as “dark matter” and “dark energy”, and can only be perceived by their gravitational influence on all the bright, shining matter we know and love. In this talk we’ll discuss why we think the dark matter and dark energy are out there, and explore some of the ideas we have for discovering just what it might be.
