$950 Million Large Hadron Collider Upgrade 'Could Upend Particle Physics' (theguardian.com)
An anonymous reader quotes a report from The Guardian: A massive project to supercharge the world's largest particle collider launched on Friday in the hope that the beefed-up machine will reveal fresh insights into the nature of the universe. The approximately $950 million Swiss franc mission will see heavy equipment, new buildings, access shafts and service tunnels installed, constructed and excavated at the Large Hadron Collider (LHC) at Cern, the particle physics laboratory on the edge of Geneva.
The upgrade will make the collider far more sensitive to subtle quirks in the laws of physics, and physicists hope these anomalies will pry open the door to entirely new theories of the universe. If the upgrade goes to plan, the proton beams in the souped-up accelerator, known as the high-luminosity LHC, or HL-LHC, will be so intense that the number of collisions in the machine will be five to 10 times greater than today. The upgrade is expected to take eight years. While new magnets and beam instruments will be installed when the LHC is switched off for two years in 2019, most of the required equipment will be fitted in a longer shutdown from 2024 to 2026, when the revamped machine will switch back on again.

Let's make that "CERN," not "Cern."
The approximately $950 million Swiss franc
What is it?
dollars or swiss franc?
you can not have both.
WE HOPE.
If the universe is someone's simulation -- does that mean the stars are just stuck pixels?
... because it should have been Texas.
They would have detected the Higgs boson first, and would have attracted the best scientific minds on the planet.
The infrastructure and support system including housing, lodging, eateries, fuel ...
The list is enormous and the impact great.
It little behooves the best of us to comment on the rest of us.
The harder you smack things together, the more and smaller the pieces will be that fly off.
Have gnu, will travel.
Actually Democrats controlled the House, the Senate, and the presidency at the time it was cancelled. They had total control. The effort to shut it down was led by Democrat Jim Slattery of Kansas.
Try this one.
i've been studying alternative theories to the Standard Model for years. by amateurs, semi-amateurs, "professionals" operating outside of the peer-reviewed process for "some reason" (see below), as well as academics operating within the peer-reviewed community: piotr zenczykowski, sundance osland bilson-thompson (yes a real person!), and many more.
the amateurs... dang. there's a lot of crap out there.
the semi-amateurs... yyeah they actually get somewhere, generally, but they tend to want to contribute to the Standard Model because that's what everyone else is doing.
professionals operating outside of the peer-reviewed process: i'll describe these below. they're extremely rare (as in: there's only really one group, led by one person)
academics: these tend to focus on the Standard Model. the two that i mentioned - piotr and sundance - actually based their work on Haim Harari's "Rishon Model": https://en.wikipedia.org/wiki/... - it was extremely popular in the 1980s but unfortunately did not go anywhere.
there's also "String Theory" which has taken literally decades of extremely talented mathematicians (reducing - or wasting - the world-wide available pool of mathematical talent in the process, was one complaint i saw made by other academics, a few years ago).
all this means we basically have a lot of effort being spent on a theory with at least TWENTY SIX completely unexplained "magic constants"! https://spinor.info/weblog/?p=...
the one exception to this is work by someone called dr randall mills, whose work started somewhere in the 1990s, and, after 30 consistent self-referencing papers (because no peer-reviewed journal would accept them) he and his team published a whopping 1750-page book containing the material. it's *dynamite*. it's the *only* one of the theories that i cannot dismiss "out of hand". it makes sense, it's consistent, it's self-consistent, there *are* mistakes, there *are* "missing pieces"... but the core makes perfect sense even to me with A-Level maths.
now, we can *claim* that increasing the power of the particle colliders would increase the detection rate of particles, thus giving a larger statistical analysis base to work from, but with the near-terminal focus being on the Standard Model, where funding is ONLY available if you are working on the STANDARD MODEL, and where deviations from the STANDARD MODEL result in you never receiving funding again... you see where this is going?
basically i am trying to point out that upgrading the hardware really isn't going to help. the academic peer-reviewed system is so broken that i have really not a lot of hope that things will change. if you are not familiar with this concept, you can google it for yourself: https://www.google.co.uk/searc...
this article - which i had never seen until now - is particularly fascinating: https://www.nature.com/news/pe... which points out that peer-review is "a response to political demands for public accountability". whilst we may claim that, in concert with internet searches and connectivity arxiv (and vixra) are helping to bypass that and allow "public comments" over time to help spot mistakes, it doesn't help with the top journals, which is what most academics read and take seriously. and if those journals are biased....
Quantum mechanics is integral to modern integrated circuit design, especially microprocessors.
Only crack the nuts that crack. You don't put the ones that don't crack in the sack.
maybe this one will be the one? can we really take that chance?
Your survivorship bias is showing. You're only here to make jokes about it because you happen to inhabit one of the one in 1e1000 universes where CERN hasn't already created a planet-devouring black hole.
But my shadow IS spying om me? AND reporting its findings to the secret FB HQ at Cern not CERN

They cancelled it out because they could not see the immediate benefit while wanting to show some fiscal austerity. While republican would not have seen the immediate interest either, they would have kept it for the money and economy it would have brought Texas, and while they are vocal for fiscal responsibility in reality it is all bluster and they are utterly fiscally irresponsible when in power.
In other word anti science republican would have kept the ssc if only for the boundangle , not caring about the science or fiscal responsibility.
Isn't that hugely ironic ?

Yet... :)
I'd suggest you read something about semiconductors
I can't even work out whether it's the collider that's large or the hadron!
Confucius say, "Find worm in apple - bad. Find half a worm - worse."
Yep, we are pedantic.
We are also all familiar with cases where missing commas or unit specification have led to million dollar losses.
Most of us encounters cases where missing semicolons causes lost productivity on a daily basis.
A vast majority of conflicts, small and large, in the world are because of miscommunication and failure to clearly specify intent.
Proper capitalization leads to misunderstandings and we don't want that.
Spending an extra minute to make sure that what you communicate can't be misinterpreted will save you a lot of time down the road.
You should try reading some proper standard specifications. Then you will realize that there is no such things as synonyms and that every choice regarding punctuation and phrasing is deliberate.
Same thing goes with legal texts, you don't get to call "tomato potato" on the law.
It is for the LHC, but it could be adapted...
I have a monorail for sale. It will upend transportation as we know it. You're gonna LOVE it!
Nothing, because rebels stole half of it and the army burned the rest.
Did I win?
Confucius say, "Find worm in apple - bad. Find half a worm - worse."
Yea yea whatever. Next you will be saying this so called "survivorship bias" means that not a single one of my parent organisms died before successfully reproducing, effectively winning the lottery a trillion times in a row. Ludicrous, I tell you.
Semiconductors and superconductors would not have been possible with fundamental research in quantum mechanics carried out several decades before such phenomena were understood. Had it been up to you, such developments would have never taken place.
The scientific community is global. The LHC is there for everybody. It is yours too! The entire point of science as we know it, is that it benefits us all.
Actually, I suggest you travel there, and notice that you will feel a sense of community with those people that share a common love with you. If you are a good scientist, you can work with them and they will want to work with you.
Cultures sticking together makes sense, as long as it doesn't result in a filter bubble. ... But nationalism is just plain absurd.
Not just because nations/states/countries aren't one culture and cultures cross borders. But generally because of how arbitrary the borders are and because any given place used to be part of more than one country/nation/state during its time.
E.g. your proud Texas was taken from Mexico. And they took it from the natives. And some day it will be taken from some new group again, and a couple of decades later, people from that new group will say the same pointless nationalist things about that new country.
If you must take the side of the group you randomly were born into, then side with those that actually form a group with you. People you can talk to and who can talk to you. Your town maybe. Your club (if you are actually a member, not a "fan", 200 miles away). Or ... you know ... the scientific community. :)
"They cancelled it ... because they could not see the immediate benefit..."
Apparently it is possible that there will never be any benefit.

Quotes:
"One thing that killed the TexasSSC was an undeserved reputation for over-spending." I don't agree with "undeserved". The project leaders did not explain their spending sufficiently that people with little technical knowledge could understand it. That was my impression.
"People have been asking which party killed the Superconducting Super Collider. The answer is... both of them. The key Senate vote came in 1993, when Democrats controlled Congress. All told, 26 Democrats voted to kill the project and 29 voted to keep it; 31 Republicans voted to kill and 13 voted to maintain funding."

Glad to help.
Mostly random stuff.
The cracks in the SM are getting too large to ignore. The LHC cannot now, nor can it ever, probe at the scales we need to correct the serious gaps in the SM. Throwing a billion dollars at it is not a good use of our wealth. If you want to throw money at something, spend it on upgrading LIGO or getting LISA off the ground sooner, which are two tools that can open new windows on the universe right now. The SM needs to be corrected, and the LHC cannot help with that.
Hopefully what happened to Praxis will not happen at CERN

Uh, Linux geek since 1999.
can somebody please convert this figure to brapples for me?
Might makes right irrelevant.
Is there a short article I can read to learn the basic terminology of particle colliders? I just need to make condescending remarks about this device and dismiss the efforts of hundreds of experts.
try looking on twitter: i'm told it's a good site for short opinions below 140 characters, 280 for more recent ones (wow!). i hear you can then use the same platform to reach millions of people with the proposed dismissive condescending remarks, too! :)
What you're ignoring is that if they do create a black hole it will be moving above escape velocity, and will have such a small capture cross-section that it could sit harmlessly in the center of the Earth.
The question is, "Could it survive long enough without emitting too much Hawking radiation to be noticed?". I have heard some people speculate that there is a minimum size for black holes, below which they can neither emit Hawking radiation nor capture incoming material even if embedded within neutronium, but I sort of doubt that conjecture. OTOH, if that could exist, perhaps it could explain "dark matter". They'd need to have been created during the big bang to avoid disrupting the Lithium balance, but why not. They should have been a time back then when things were dense enough to seed them, and if they're that size, the seeds should have been sterile (i.e., neither able to evaporate nor to grow). But this depends on such a minimum size existing.
I think we've pushed this "anyone can grow up to be president" thing too far.

Socialism: a lie told by totalitarians and believed by fools.
"So...you're saying it was physics research."
I think most people won't understand why that's funny.
I've worked with Physicists who were distant from the social world.
He's a Democrat. They are democrats. The Democrats cancelled it. That's basic shit. Democrats hate science. It tends to get in the way of their solution to everything - more taxes. Then they try to go for emotional stuff, like the separating children BS with pictures taken during Obama's term and a decision by the 9th circuit. Yet somehow it's Trump's fault? When this fails they'll find some other BS to fling upon us. They have nothing else. Nobody is running the Democratic party right now except a few really old delusional fools.
