Topological photonics can force propagating light to travel in a single direction—allowing researchers to route optical signals around corners and past defects without any of it scattering backward. So far, however, this one-way flow has only been found at the boundary between two specially engineered "topological insulator" regions, leaving most of the material unavailable for light transport.

Spider-Man: Brand New Day is on the verge of breaking an MCU earnings record previously set by Avengers: Endgame with its day one numbers, which could be higher than $70 million on a single Thursday.

That, it would seem, lead to the arrival of a second Spider-Man, without the disappearance of the other.
