Moon Collider

I wanted to post this but misplaced it and then struggled to figure out what it was. But here it is again, found! Tl;Dr version: what if they built a particle accelerator encircling the whole moon? Damn!

The article suggests it would be buried in the moon, but I like your idea better,
especially if they dual purpose it with a moon scale rail gun...just in case.

Ah, buried! I honestly having trouble figuring it out but I think I see what you mean. Either way - it's on the moon!
