SUMMARY
The discussion centers on the finite time required for an electron to absorb a photon, emphasizing that this process is not instantaneous. It is established that interactions in the universe, including photon absorption by electrons and phonons, take a finite amount of time to avoid issues related to infinite energies and faster-than-light causality. The key equations presented are Δt ΔE ≈ h-bar/2, which relates the time of absorption to the energy width of the excited state, and Δt Δω ≈ 1/2, which can be derived from electrical circuit principles.
