I feel like the title is a little overdramatic. They’re not saying goodbye to the LHC, they’re upgrading it to have 10x the power.

I had to chuckle a week or so ago when I was bumbling across the internet and landed on an article that had a link to a nutjob page where the title was something like: "CERN found something so disturbing they had to shut down immediately".

The nutjob article (yes, I did read it, LOL) suggested that they had found some universal truth maybe about God or aliens or something, and it scared them so much they just noped out of the science business to prepare themselves for the inevitable revealing of the "truth".

It is truly no wonder that so much of society is so fundamentally fucking stupid when their trusted information sources are so full of obviously false bullshit.

I can't wait until the LHC is back online zipping tiny things around the ring again in a cosmic demolition derby to find the smallest specs of our reality and give them all whimsical names.

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.

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.

I wonder whether the cancellation of the superconducting supercollider was a net positive or negative for science. If it continued to completion, it would have had almost 3x the beam energy of even the upgraded LHC in 2030 (20TeV vs. 7TeV). But the questions are fundamentally political, not scientific: Would SSC operations and funding have continued through the US economic challenges of 2001, 2008, and 2020? I could…

From what I've heard, the SSC would have had higher power, but much worse luminosity (i.e. much more noise) than the LHC.

The typo that sometimes got through in official literature still makes me giggle https://www.google.com/search?q=site%3Acern.ch+%22large+hard...

Maybe some enterprising Las Vegas citizen will jump at the opportunity to turn that idea into a hard asset.

I worked on a tiny, tiny part of the research for the insertable B layer in ATLAS during long shutdown one as an undergraduate - the 3 year period allowed all the detectors to be upgraded significantly! It will be interesting to see how the current systems are upgraded during this shutdown. Sounds like the ITK for ATLAS is absolutely _insane_ compared to the insertable B layer - 5 billion channels, up from 8 million. I wonder if ITKpix is at all similar to the T3MAPs cmos or FEI4 sensors we worked with…

Edit Looks like it’s very different; and really cool: https://cds.cern.ch/record/2928802/files/ATL-ITK-PROC-2025-0...

Probably because the upgrades to the collider are so significant that it will be called the HL-LHC afterwards.
