Description

Proton is our stable microscopic platform, allowing four forces - strong, electromagnetic, weak
and gravity to act in terms of their respective form factors, where the gravitational form factors
describe the hadron’s mass, spin, and D term. Recently, in 2018, the D term has been extracted
from the experiment and pressure distribution inside the proton is sketched. The shocking part of
this results is that the pressure near the center of the proton is crossing the value of neutron star
pressure. Present work has attempted to understand this shocking pressure distribution in terms
of a simple version of classical and statistical physics. This attempt does not claim about realistic
explanation of proton pressure distribution but may be considered as crude visualization to compare
our existing aspects of classical and statistical physics.
