This month, scientists at CERN will be restarting the largest human machine ever built: the Large Hadron Collider. In honor of this scientific milestone, we invited Dr. Reyco Henning, UNC assistant professor and particle physicist, to our November current science forum.

I can’t speak for the entire audience, but he blew my mind. The scientists studying particle physics have to be some of the most intuitive and creative scientists on the planet. I can only imagine the answer a particle physicist’s child gets when he asks, “Mommy, how did we get here?”

These people spend their lives creating incredibly complex theories to be tested by mind-bogglingly intricate machines in the hopes of understanding the fundamental nature of the Universe. How did it get here? What is the origin of mass? What is the nature of dark matter and dark energy?

Some fun facts from Dr. Henning:

1. Matter is mostly empty space. If Kenan Stadium represented a whole atom, the nucleus would be the size of a golf ball.

2. In the currently accepted model, most physicists estimate that the universe is 73% dark energy, 23% dark matter, 3.6% intergalactic gas, and 0.4% stars.

3. The LHC has had over 3,000 scientists from all over the world work on it at some point.

Henning’s take home message: The LHC will be creating decades of data that will go a long way to confirming, reforming, or rejecting our current conceptions of matter and the Universe. Let’s hope that no more birds or bread get in the way.

Next month: Dr. Kevin Weeks will be talking about his team’s decoding of the an entire HIV genome. See you on December 3rd at 7pm.


ps — In doing a little research, I was unsure about the “largest machine claim” so I did a little google magic and came across this beauty of a blog. The Bagger 288 is no joke.
