Geneva already has a Doctors Without Borders, so allow me to make this pun: CERN is science without borders. Located underground across both Switzerland and France, the donut-shaped LHC is over 26km in circumference and advances scientific knowledge. It’s too complicated for me to understand so I’d highly recommended you visit it’s two public museums.
The one in a ball- shaped building is the Universe of Particles, but I like Microcosm more. Located underground, Microcosm invites visitors to discover and learn about the LHC and unanswered questions of the universe. A 1:1 scale of the LHC tube is illustrated for visitors and models explain it’s inner workings.
Although there are still a lot of unanswered questions in the world of physics, it’s honest about what it knows and what it’s still trying to figure out. Unfortunately, the public are not allowed to tour the actual facility so they put a part of the wire chamber from 1983 on display. This is as close as anyone can get without knowing someone inside CERN.
Another thing I really enjoyed about the museum is that it’s free. Science should be free and accessible to everyone and I’m sure CERN also subscribes to those values, too.
