Saturday, Sept 5, 7:00pm in the GSU Student Center Speaker's Auditorium 

Dark Matter: MACHOs vs. WIMPs, a debate of truly astronomical proportions.  

Dark matter, like the popularity of Justin Bieber, is one of the biggest 
mysteries of the 21st century. This unseen material makes up 27% of the 
universe's matter and energy, while normal matter (like protons and electrons) 
only makes up 5%. Yet despite over 70 years of study by numerous physicists 
and astronomers, the nature of dark matter is still unknown. Two of the 
leading scientific theories propose that dark matter is composed of a new type 
of exotic particle (WIMPs: weakly interacting massive particles) or mundane 
clumps of normal matter like planets and burned-out stars (MACHOs: massive 
compact halo objects).

Join us for a public debate where two of our esteemed faculty, Dr. Todd Henry 
and Dr. Rachel Kuzio de Naray, will face off and attempt to convince you that 
one of these dark matter theories is more compelling than the other. In the 
spirit of such classic rivalries as David vs. Goliath, Bilbo vs. Smaug, and 
Antman vs...well, anybody bigger than an ant, we bring you MACHOs vs. WIMPs! 
Who will be the victor? You decide.
