What's next? Planck's constant?
It so a cook can't keep up with physics anymore.

Odd how this ‘measurement’ of the proton is very similar to our claims of the size, orbit, and viability of planets around other stars.
We can’t see the planets.
We only have light detectors that give us a reading of very minute dimming in the light, which we assume to be a planet.
Based on the length and extent of the dimming, we claim to know the planet’s size and orbit.
Amazing how continuously wrong we are about things we search for the truth.

First: The Standard Model doesn't describe gravity, period.
Second: Physicists aren't desperate to "discover new physics." We're desperate to wring information out of experimental physics in new ways because the approach of reaching ever higher energies in our accelerators is simply not viable. We can't even get within orders of magnitude needed to investigate most speculative theories in high energy physics, and there is no prospect for doing so in sight.
We need new experimental results and we just aren't getting any. Hence micro-measurements of the difference between c and the speed of neutrinos in vacuum or anomalous results like this start to look intriguing. They seldom turn out to be anything but experimental artifacts.
And no, we aren't changing Planck's constant. In fact, in the new SI proposal, Planck's constant, the electric charge, Boltzmann's constant, and Avogadro's number are going to be set as defined constants; they will never change. What will happen instead is that the basic practical units (second, meter, kilogram, ampere, kelvin, mole, and candela) will change and we will be looking for ever sharper definitions of the practical units in terms of the atomic ones, instead of the other way around as we did in the past.
High energy physicists and cosmologists have been doing that for a long time already. In their unit system ħ = (h/2π) = c = 1.
Question for Physics majors....
Is Particle Physics built on the idea that EVERY similar particle in the universe has EXACTLY the same weight, dimension, and charge as every other similar particle?
Or, is there some level of acceptable deviation?

Remember the blog about quarks? I figure that’s next up.
Relax. The entire physical universe is an illusion. We perceive what we project.
Protons have been on a diet so that they will look good in a swimsuit this summer.
Use millimeters so you are closer to actual size. This would be using Euro's to determine our national debt.
