Beyond the Looking Glass

The possibility of seeing the many worlds of Hugh Everett has never been seriously discussed until the advent of metamaterials, tech that not only bends light in opposite direction ( negative refractive index) from ordinary materials but also can tune the electromagnetic spectrum in ways impossible to do until now.

"In the research paper, the researchers from the Hong Kong University of Science and Technology and Fudan University in Shanghai describe the concept of a "a gateway that can block electromagnetic waves but that allows the passage of other entities" like a "'hidden portal' as mentioned in fictions."

The gateway, which is now much closer to reality, uses transformation optics and an amplified scattering effect from an arrangement of ferrite materials called single-crystal yttrium-iron-garnet that force light and other forms of electromagnetic radiation in complicated directions to create a hidden portal."
