The Quantum chromodynamics (QCD) Lagrangian, which is part of the Standard Model of Nuclear and Particle Physics, describes interactions among quarks and gluons. These fundamental particles are bound inside protons, neutrons and other hadrons, yet are never seen directly in nature. Empirical evidence suggests that QCD is a robust theory; however, it does not directly describe how quarks and gluons make up protons, neutrons, and ultimately atomic nuclei. We utilize electron scattering experiments to understand the evolution from quarks and gluons to protons and neutrons. CEBAF at Jefferson Laboratory produces a highly polarized, high-luminosity, 12 GeV electron beam to study this fundamental question of nuclear physics. In this talk, I will describe results from experiments today, where they will lead in the future, and their connections to the cosmos in which we all live.**Relevant background with commentary from Speaker:** //A few papers…// * [[https://www.tandfonline.com/doi/epdf/10.1080/10619127.2025.2485831|Nuclear Physics News Laboratory Portait: JLab (2025)]] * [[https://www.innovationnewsnetwork.com/quantum-chromodynamics-at-the-intensity-frontier-with-a-precision-microscope/52920/|Innovation News Network: Quantum chromodynamics at the intensity frontier with a precision microscope (2024)]] * [[https://journals.aps.org/rmp/abstract/10.1103/RevModPhys.95.041002|RMP Colloquium: Gravitational form factors of the proton (2023)]] - (JTS: just sections I and II) * [[https://www.mdpi.com/2073-8994/17/7/1106|Electroexcitation of Nucleon Resonances and Emergence of Hadron Mass (2025)]] * //The [[https://nuclearsciencefuture.org/|long range plan]] has a lot of JLab results in it.//
