I spent way too long trying to figure out why the guy and the ice cream shop were flying, and how he would move horizontally in he air…
I couldn’t tell what I was looking at until I searched for an explanation. All I could see was a person falling into some water past a floating ice cream stall. It’s supposed to be a beach:

“we have a beach at home”
the beach in question
If like me you can’t see the picutre of the post, here is the original image:

What’s up with that? I can’t see any of the pictures hosted here.
I’m not positive but it might be due to the steps the Lemm.ee admin is taking to combat the CSAM uploads that have been happening and prevent the server’s administration team from being liable for potentially harmful and illegal images being hosted on their server.
and I thought this had to do with light refraction lol
It is simply polite to include a link to the original https://xkcd.com/2821 as per the Artist’s desires.
Yes, I saw the explain, but that isn’t to the actual origin.
Path that maximises time would be some kind of space-filling curve. Maybe it does that off panel?
path that maximizes time? just don’t move. at all
It’s to do with light paths and diffraction. The time maximising path still hast to be a valid path.
