Density of a subatomic particle

Click For Summary
SUMMARY

The density of a proton can be measured, as it possesses a defined size, volume, and mass, allowing for the calculation of its density. The discussion highlights that while protons have a measurable density, the concept of density may break down in extreme conditions, such as within neutron stars, which, despite their larger size, exhibit similar density characteristics. This indicates that density remains a valid concept for subatomic particles under certain conditions.

PREREQUISITES
  • Understanding of subatomic particle properties
  • Basic knowledge of density calculations
  • Familiarity with neutron star characteristics
  • Concepts of volume and mass in physics
NEXT STEPS
  • Research the density calculations for protons and neutrons
  • Explore the properties of neutron stars and their density
  • Study the implications of density in quantum mechanics
  • Investigate the limitations of classical physics in measuring subatomic properties
USEFUL FOR

Physicists, students of particle physics, and anyone interested in the properties of subatomic particles and their measurements.

Can this be measured? ie - "What's the density of a proton?" If so, what exactly are we measuring?

If not, at what point does density as a concept break down?

Apologies if this needed to be under the "Classical" forum.

No, OK for proton. Proton has a certain size, volume and mass, so the notion of its density is correct. Neutron stars are larger but have similar density.
