It sounds esoteric, like an episode of The Big Bang Theory, and maybe someday it will be. But even in the fields of physics, supersymmetry is esoteric. What is supersymmetry? What is the calamity? Why should you care?
What it is... is an idea: particular superheroes! Here's their story.
The standard model is the crown jewel of physics. All you need to know is it describes subatomic particles and the forces that affect them. It has 16 kinds of particles: six quarks, six leptons and four bosons. Lately, headlines tell us add the Higgs. The standard model depicts the world at the smallest scale physics has reached so far. With exquisite precision, it calculates results of smashing particles. But it explains nothing. Indeed, it leads to unsolved mysteries like: Why doesn't the entire universe collapse into black holes? And: What is dark matter?
Some 40 years ago, our particular superheroes came to the rescue. Imagine a comic-book world called superspace. A fourth dimension where each particle physicists have found has a partner-particle they haven't found. Why a comic-book world? Well, the whole idea of supersymmetry is still imaginary. Decades ago, the authors of Superspace (a serious text) said:
The most striking feature of the relation between supersymmetry and the observed world is the absence of any experimental evidence for the former in the latter.
This is still true. Even so, for four decades physicists have manipulated the math of superparticles to show how they solve standard model mysteries. Meanwhile, they have built the world's biggest machine to find experimental evidence of superparticles. It's a particle smasher (the Large Hadron Collider or LHC). It got off to a shaky start. But now it's working; and now -- as the Music Man says -- there's trouble in River City. After scanning many trillions of smashes, the LHC sees not a single superparticle! My quote-of-the-year award goes to American physicists Joseph Lykken and Maria Spiropolu:
"The negative results are beginning to produce if not a full-blown crisis in particle physics, then at least a widespread panic."
So here are my predictions for hot physics news in 2015: The LHC will work up to full power. It might find a superparticle. If so, the particle will get an ugly name that starts with s. Then physicists will hunt more superparticles. They will need a bigger atom smasher costing multi-gigabucks. With it they will expand the standard model on a firmer foundation. The main effect of superparticles on you and me will be we'll share the costs. The effect on the world economy will be modest; we won't notice it.
But what if the LHC works up to full power and finds no superparticles? Then: No superheroes, so no rescue. The standard model will be ridiculed: the standard muddle, 40 years of fundamental physics consigned to the comic books. Funds for smashing atoms will be in short supply. Physicists will drive cabs. The main effect of all those trillions of non-events on you and me will be: They will transform our world. How so? Well, the world economy is getting sluggish. It needs new physics. We will find new physics when old physics crumbles. New physics will create a new economy as inconceivable to us as smartphones, social media and Google were 40 years ago. Spending all those gigabucks to show there are no superparticles will seem a steal.
Which way will it go? What do you think? My bet: The old physics is all set to crumble.

You do an excellent job of explaining physics to those of us who are not smart enough to learn it on our own.
Thanks for clearing up my “superparticle” misunderstanding.
And, the subject of “indistinguishable” electrons is something I've thought about and read about before.
Your discussion was very helpful.
When it comes to sports you can always find a differing opinion. Kind of like economics. Harry truman once said he wanted to hire a one armed economist, because all of his economic advisors qualified everything with "on the other hand." ESPN would surely have ceased to exist long ago if their opinions could be subjected to the same objective standards as physics.
As a guy who doesn't believe he was small, slow and white in his long ago prime, let me take a parting shot:
Dick Butkus, who Tom Brady is happy is doesn't have to face. [Small, slow, and white.] 
Tony Dorsett, 100% faster than any white guy, discovers Jack Lambert is small, slow, and white...
Great quickness, great anticipation, great tackling mechanics, but his 40 speed, which they did run for time back then, was never below 5.0.
Butkus would struggle with pass protection in the modern era.
2015 tight ends are as big or bigger than he is, and Butkus lacked the lateral speed to keep up with any of the 2015 slot receivers.
I can't find a 40 time on Lambert, but at 6'4” 220 pounds there would be no defensive position he could play in 2015.
He'd be too slow to play strong safety in 2015, which I think is 100% Black.
He would probably be an elite Special Teams player.
If he had good hands, they might be able to make a situational receiver out of him, specifically in the Red Zone or in multiple tight end formations.
Dorsett weighed just 192lbs, almost 30 pounds less than Lambert.
The photo is clearly a pass play, and Dorsett clearly caught it with his back to Lambert.
Even in the 1970’s, a choke hold tackle like that would draw a flag.
By the way, I come from a family of football fanatics, and I've seen almost every player we talked about, including all 9 home games of the Dolphin's perfect season.
I never saw Otto Graham play, however.
BTW, Troy Polamalu is not Black.
He runs (or ran) the 40 in 4.3-4.4.
The idea that Lambert ran that fast is not serious.
Bottom Line:
The superstars of this era may not have been superstars in earlier eras.
But - Lambert, Graham, and Butkus would not - could not - have been superstars in this era.
The game rules changed, and the players and draft scouts have changed with them.
I think the rule changes were good.
I don't want to watch second and third string QB’s start the Super Bowl because of “sitting duck” injuries to the starters.
And the modern day legal and political environment makes the violent injuries of previous eras untenable for modern day team owners.
God should really come down from on high and explain His creation once and for all.
