Negative permittivity Memes

Breaking physics is apparently more concerning to the government than breaking into Area 51. The notation ε<0 refers to negative permittivity, which would allow for some truly bizarre electromagnetic phenomena like negative refraction and perfect lenses. Basically, you'd be running away with the ability to bend light in ways that violate conventional optics. The guards aren't chasing you because you trespassed—they're chasing you because you've stolen something that could collapse our understanding of physical limitations. Typical Monday in theoretical physics research.
