Doesn't four quarks and one antiquark = 3 quarks?

And, of course, this all happened by chance after the Big Bang! Yeah!
To: js1138
....this recent news is certainly met with excitement...
And I thought I needed a life.

And, of course, this all happened by chance after the Big Bang! Yeah! Just what is chance? After all, even probability is governed by laws. Ever seen a fractal or a Mandelbrot set?
Seemingly impossible order out of sheer chaos. Funny how the Mandelbrot set appears EVERYWHERE in nature; in the shape of the mountains, or a tree, or a leaf . . .

Nice. Theory predicts something rather weird. Then experiment finds weird thing.

Doesn't four quarks and one antiquark = 3 quarks? No, a particle and an antiparticle annihilate each other only if they're of the same type -- for example, an electron and a positron (anti-electron), but not a proton and a positron.
There are six kinds of quarks, called up, down, top, bottom, strange, and charm. Each type has its own antiquark.
The five constituents of this newly discovered particle are said to be two up quarks, two down quarks, and a strange antiquark. There is no matching quark-antiquark pair here.

OK, physicist, would you mind putting this in english for me, or is this as far as the translator goes?
Good find js1138, thanks for the ping!

You know I think the Supreme Court is made of of 6 quarks and 3 antiquarks.

the Jefferson lab has approved an experiment intended to boost its pentaquark production 20-fold
NO good can come from this, I'm telling you.
The ruination of mankind, famine, pestilence, degradation and death, all can be traced back to the Pentaquark.
Yada,yada,yada....
