How Pentaquarks May Lead To the Discovery of New Fundamental Physics
StartsWithABang writes: Over 100 years ago, Rutherford's gold foil experiment discovered the atomic nucleus. At higher energies, we can split that nucleus apart into protons and neutrons, and at still higher ones, into individual quarks and gluons. But these quarks and gluons can combine in amazing ways: not just into mesons and baryons, but into exotic states like tetraquarks, pentaquarks and even glueballs. As the LHC brings these states from theory to reality, here's what we're poised to learn, and probe, by pushing the limits of quantum chromodynamics.

How does this relate to string theory ?

In one sense that seems to be something you really can't do. The force between free quarks increases with distance to about 10,000N, then remains constant (no, I have no idea how this makes any sense, but it's what I read). Any force sufficient to tear two quarks apart is sufficient to generate new quarks which then bind with the "free" quarks. So you never see quarks by themselves.
IANAP, though. Does the above really mean that if you had two free quarks separated by a kilometre or a light year, that there would still be that constant 10,000N force between them?
systemd is Roko's Basilisk.
This is not a summary, but a teaser. Let's keep that kind of bullshit off Slashdot.
Actual summary:
"Recently, the existence of pentaquarks, predicted by quantum chromodynamics, was confirmed. This sortof validates quantum chromodynamics. [Intro to quantum chromodynamics]. We could find many more particles predicted by quantum chromodynamics in the future!"
Is there some internet meme I've missed at play here, or is it just a moron poster who *loves* cows??

I tell you where it's from
Physics
That's from where glubola comes
West side
It hides in the suitcase
Two days later
It lands in USA
I get it from my girlfriend
And give it to my dad
I catch it on the subway
And leave it in the cab
I eat it at Subway
I drink it at Starbucks
glubola's everywhere
And I give no fucks
They scared
It's bad
glubola's gonna kill us all dead
They mad
How'd this happen
Gotta make sure that nobody else gets it
I'm sorry but you have it and I have it
But you'll get it so forget it
Don't sweat it just let it be
I'm telling you glubola's not the enemy
Listen
I have glubo (La la la la la)
And you have glubo (La la la la la)
And we have glubo (La la la la la)
Everybody has glubo (La la la la la)
Selena has glubo (La la la la la)
Justin has glubo (La la la la la)
Taylor has glubo (La la la la la)
Jesus has glubo (La la la la la)
glubola
Every shitty little collider in CERN
Has glubola
Every city in America is getting it now
Just go with it bruh
Airports ...
Check if he's geek
He could have glubola
So send him back
In fact keep an eye
On the Marie Curie
Mostly Curie
Don't worry about Marie
And the Hawking's
Could have glubola
Also Bill Nye
Let's just close up Fermi
Until this crisis is contained
Don't let the Tyson's
On the plane
"They might just be eigenvalues of particle properties, nice to calculate on, but not necessarily anything real in themselves."
Well that describes the proton surely? Prior to 'deep inelastic scattering' experiment, the proton was believed to a fundamental particle and QM was applied and QM believers referred to the proton being detected as at a position. That "the proton is everywhere till we detect it at a location and that fixes its location" nonsense*.
Post DIS, we know that its not fundamental, rather made of sub-particles, hypothesized as Quarks (to fit observed data) and later added to to better fit observed data. So the proton was never 'at' the detected location, it was only *detected* to be at that location by the effect of these quarks on the detector. i.e. a proton is " not necessarily anything real in themselves" as you put it.
So much for QM.
Quarks are IMHO too complex a model and given every particle exists with an anti-particle and the only difference is the charge, then you're better off looking for just two particles, a + and a -. But that's just my opinion.
* Because its a way to explain a conflict in physics: single indivisible particles, that jump around randomly based on probabilistic math. But the basic model is comic, it assumes something special about *our* detection of the particle different from its interaction with every other piece of matter it interacts with. Of course there is nothing special about 'our' detection. Thus the model is flawed.
The probalistic maths is from observation, so the indivisible particle must be the flaw, and that's already been shown with a proton. i.e. QM is just a flock of starlings seen through a detector that can only see the flock.
My wife is a particle physicist, a staff member at one of the top physics labs in the world. We used to go to Lake Victoria in the Canadian Rockies every year for an international conference on that subject. I'd spend the day skiing. She'd spend the day in meetings! :-) Fortunately, the conference sessions were only in the mornings and evenings, so we had the afternoons free for cross-country skiing together.
Like "Soylent Green is people" I thought everyone knew that.

My balls are glued for the continuation of this story. It could be made to a nice catastrophe movie, with developing characters, emotional content and all.

..but I have no idea what any of it means.
THERE ARE NOT 5 QUARKS, BUT 20 QUARKS ROTATING THROUGH 4 24-HOUR DAYS IN THE 4 CORNER CUBE EARTH. SCIENCE EDUCATES YOU STUPID. YOU BELIEVE IN CHILD-KILLER GOD PARTICLE. LEAVE CHILD ALONE IN ROOM WITH GOD PARTICLE; CHILD DIES OF STARVATION. YOU CAN'T UNDERSTAND 20 QUARKS BECAUSE YOU THINK 1+1=2 INSTEAD OF 1+1=8. THIS IS WHY GOD EATS YOUR CHILDREN AND SHITS YOUR 5 QUARKS INTO SCHOOL KIDS FROM THE SCHOOLTEACHER'S DIRTY MOUTH.

Early discoveries and hypotheses on small stuff have led to immense improvements in chemistry and electronics, and the development of nuclear power. Is there even a hint of a notion that this sort of work is going to lead to something practical? If so, what?
