Summary

This episode explains how the James Webb Space Telescope works, its infrared capabilities for observing early galaxies and exoplanets, and the proposal process for accessing its data. It also addresses viewer questions on the strong force, clarifying how nucleons bind via meson exchange and linking gluon flux tubes to string theory origins. Finally, the hosts discuss the Higgs boson's potential role in dark matter research and the importance of future collider experiments.
