eli5: What exactly does the Large Hadron Collider do, and why are people so freaked out about it?

Bonus points if you can explain why people are freaking out about CERN activating it during the eclipse specifically. I don’t understand how these can be related in any way.

There is no connection between the eclipse and the LHC. Anyone spouting off nonsense about that is either trolling or they’re just a complete idiot.

The LHC is a particle collider, the largest one that humans have ever built. It accelerates tiny collections of particles to extremely high speeds and then steers them so they crash into each other. These super high energy collisions smash the particles together and in these immensely energetic collisions different types of particles can be produced. The LHC has a bunch of different detectors to measure what comes out of the collisions, and these experiments are used to test theories about particle physics.

The eclipse makes zero difference to the LHC. The LHC is in Europe, and isn’t even in the path of the eclipse. There have already been many solar eclipses since the LHC started operating.
