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 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.
Probably because the upgrades to the collider are so significant that it will be called the HL-LHC afterwards.
Hella Large - Large Hadron Collider?
I think it stands for Huge Large Large Huge Colossal, in reference to its size.
High luminosity large hadron collider
They missed an opportunity to add 'Colossal' to the beginning, so the acronym would be supersymmetric -- the CHL-LHC
Ho-Ly - LHC maybe.
They're collecting 10X more data, at roughly the same energy per collision.
The article says "10x luminosity", and here's what seems to be the explanation.
https://en.wikipedia.org/wiki/High_Luminosity_Large_Hadron_C...
That's the wiki article for the new one. Says "Increasing LHC luminosity involves reduction of the beam size at the collision point, and either the reduction of bunch length and spacing, or significant increase in bunch length and population."
The linked article says the new one will have "between 140 and 200 proton–proton collisions in every bunch crossing, compared to around 60 during the last LHC run." So the "10x luminosity" seems to be composed of ~3x more protons at a time along with presumably a ~3x tighter focused beam.
luminocity is collisions per second
energy is per individual collision
can't increase energy that much without increasing radius
Yes, but nobody is seriously describing the beam "power" in Watts, they mean power in a statistical discovery sense.
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 treat these nutjob articles as a subgenre of science fiction and when they're somewhat well written find them very entertaining. The author cosplaying investigative journalist, one part of the audience acting as if it's a real discovery and another part playing debunking and outrage, is all part of the performance and it's hilarious. Check out the flat earth movement, it's great entertainment all around!
One of the more popular "explanations" of the Mandela Effect is that CERN broke time somehow.
And of course there was the whole panic about them creating a black hole and destroying the world that was popular enough to make mainstream media.
Sometimes I wonder if we actually deserve science as a species.
> It is truly no wonder that so much of society is so fundamentally fucking stupid
It's not. You got baited into thinking this is the case.
> are so full of obviously false bullshit.
Well, maybe what's less obvious is that there are a lot more people gawking at how stupid other people can be than fools falling for the bullshit you call out.
My reaction as well.
I was like, "They are abandoning LHC? How come I never heard of the big news?" Turns out the title is absolutely misleading.
Luminosity, not power!
