On FTL and causality: add new time. Light vortices look a lot like a light cone on a time-space diagram to me.

Do photons have spin...? Long Covid sucks.

While we all live in a money-obsessed hellscape, nothing needs "utility" to be worth testing or knowing.

9:40 ok, I get we all live in a money-obsessed hellscape, but nothing needs to be "useful" in order to be worth learning about, appreciating, or observing at all.

But yeah, I am confused about the polaritons. 
(Polaritrons? I'm not hearing stuff / processing audio precisely, lately. ) Light has a shape? Or, like, a shape in time? Cuz that -3, -2, -1, 0, +1, +2, +3 image looks a lot like a light cone on a time-space diagram. To me, at least. The things with the light at diagonal lines in space.

Wait. Spin? Do photons have spin? I'm gonna get a used copy of my uni textbook off someone and try to remember anything. Yaaay Long Covid! (Twice, Doubled, or Squared! Per your preference.)

On how faster-than-light info would affect (our understanding of) causality: "And then nothing makes sense anymore." Since when has science stopped testing things that seemed "unintuitive" on the first pass? 
Wouldn't that just sort itself out, and then we'd make new inferences to test? Cuz it sounds like an additional dimension of time would be useful here. Which... is probably a meme. "Just add a new dimension!" Ok yeah, but what if we did tho. (Eddie Woo intensifies.)
