The LHC is such a crazy thing; kilometres of strange infrastructure, thousands of people, all for what seems like pure scientific curiosity. I think only surpassed by the SETI program in terms of doing it because many nerds think it's really cool.

Politicians think it's a moonshot project at finding another nuclear bomb type of thing. (None of this would ever be funded without the tenuous nuclear weapons connection.)

I was visiting CERN on one of their Open Days during the previous shutdown. This is one of the rare occasion where visitors can enter the LHC. I walked for about 500m along the beam which is remarkably small despite all its protection.

Standing inside LHCb (one of the experiments where they track collisions) was one of my most awe-inspiring moments about science and technology. Photos don’t do it justice. It’s a multi-story building underground, but every inch is covered with cables, sensors etc. Seeing it on photos is one thing, standing inside the biggest machine built by humankind is a completely different experience and hard to put into words.

The amount of thinking and planning that went into it is insane. CERN staff is super-friendly and open to talk and explain. If you have the possibility to visit, do it - especially with guided tours and on their annual Open Days.

I was surprised to see .cern as a TLD - i would not expect it to need a family of websites in the way .gov or .mil do.

To be fair, if any org deserves a vanity TLD it's CERN

Yeah, given that the web was basically invented there, it seems pretty reasonable

As a high school kid taking physics, we got to tour the Superconducting Super Collider campus. Obviously, this was nothing compared to being next to something that was actually built and did science, but they had a the various instruments and segments the beam tube with the magnets on display. Some students would intern there during the summer. The plug was pulled by Congress before I could apply. That was my introduction to politics in science where the kid like notions of how things worked were shattered.

I felt a similar way when I visited the Gran Telescopio Canarias, a 10.4m telescope in La Palma in the Canary Islands. It’s hard to take pictures of the entire telescope because it’s so damn big. I love experiencing the feeling of being in awe.

You can still tour the SSC. Just requires wire cutters and a bit more spelunking.

That doesn't sound like something one would want to do in cooperation with the entire rest of the world.

I spent a week there between the LEP going offline and the LHC going online on a school trip - the scale of it is just unreal - as you say, photos are one thing, but as you stand there in a vast subterranean cathedral looking up at the frantically complex detectors (we hung out with ATLAS a fair bit) it’s… awesome. In the very literal sense of the word.

Don’t know if you visited the antiproton decelerator/LEAR but they’re similarly unreal - a vast cavern, half a dozen stories high and so large it fades into blackness beyond the floodlights illuminating the various buildings and experiments within there. You descend in a rickety cage loft surrounded by no more than a box of girders, to be greeted by a vision straight out of sci-fi. Vast lead megaliths tower around like the work of some very precise techno-druids, cables and ducts snake across the floor to join unknown experiments occluded by the henges, and in this place, they make the stuff the universe abhors.

Wild stuff.

Oh, I also got to tool around on Tim’s computer which was just sat in the cafeteria at the time.

CERN is so big that they have their own IXP: https://cixp.net/ Also, the web was invented at CERN, so like the other comment said, if someone deserves at gTLD is them.

Actually, in the 2000's CERN was the biggest internet exchange point in Switzerland, while the physical datacenter was not in Switzerland but in France xD
