What are electricity and light, really? – Dr. Daniel Whiteson (CERN, LHC), DemystifySci #394

In this second part of our conversation with CERN & LHC
particle physicist and UC Irvine professor of physics and
astronomy Daniel Whiteson, we move from abstract questions to
concrete examples, asking what electricity, magnetism, and light
might actually be doing in the physical world. Rather than
treating forces as symbols in equations, we explore whether they
can be understood as real interactions, actions, or material
processes unfolding beneath the math. The discussion ranges from
fields and particles to emergence, scale, and why so many
explanations stop just short of physical clarity. We are trying
to picture what’s happening when the universe acts, while
refusing to let understanding end where calculation succeeds.
