DENVER — The size of a proton, long thought to be well-understood, may remain a mystery for a while longer, according to physicists.
Speaking today (April 13) at the April meeting of the American Physical Society, researchers said they need more data to understand why new measurements of proton size don't match old ones.
"The discrepancy is rather severe," said Randolf Pohl, a scientist at the Max Planck Institute of Quantum Optics. The question, Pohl and his colleagues said, is whether the explanation is a boring one — someone messed up the measurements — or something that will generate new physics theories.

Bush’s Fault
global warming is the cause
They thought the universe was expanding. And now the truth comes out....we’ve been shrinking.
5.56mm
Both protons and mesons are composed of quarks (3 in a proton, 2 in a meson), so that makes them lumpy, not spherical. How do you measure the radius of a lump?
Good news! I have some pants. that are getting pretty tight.
...the more we learn
the more we know
we don't know anything
So funny..we all think of Costanza...
The universe is winding down. Protons have no choice but to diminish. It is all Obama’s fault. Obama not only diminishes America, he diminishes the universe itself. And so it will be until a real natural born American becomes president of the US and we are exceptional once again. Then the universe will expand and the proton will gain weight.
Man-Made Global Warming.
What's in a proton?
I know nothing. This is a confirmation.
These guys are a bunch of quacks/quarks....whatever...
It IS shrinking but the price stays the same and the manufacturer hopes you won’t notice!
At that scale of distance you can't talk about the location of a quark but only the probability of its being in any given location. The probability distribution of quarks in a proton in its ground state is spherical.
You guys are making fun of this article, but for me, it could be a matter of life and death. I just had a cancer treatment using protons as bullets. If the protons they used are bigger than they thought, they may have killed more tissue than they wanted to. It’s a lot different to be shot with a .22LR than a .45HP. Right now, I think they used those .45 Talon type protons. I hurt all over.
Prayers for your quick recovery.
In such medical applications it’s not the size of the protons that matters though, it’s how they are used.
“measurements are simply wrong.” Silly boy! This will require great gobs of money to clear up.
That's what the ladies say ... until they see my protons.
