I believe “The Orb” is actually a concept that holds a lot of power on these forums.
It’s an idea that can easily spread and is enjoyed. If you look at memes on here right now, you’re constantly being forced to “ponder” (or think about) it, which isn’t even something I’m complaining about.
It can plant itself (at least temporarily) in your mind. Since it’s also associated with so many things (like wizards and fantasies), it can encourage you to think about things in a certain way.
Geometrical set theory is also an important “Orb pondering concept”, along with the Physics of objects like black holes.
If you can visualise a C2 rotation of a 3D shape in your head, you can also add that to a computer program describing a simulation of a physical system.
Try pondering a cube and think about what group theory transformations it has. Well, a sphere has all the group theory you could ever ask for and you can do practically anything you want with it without noticing any change on the outside. That’s the special property of a 3D Orb (hollow sphere).
It also describes why so many physicists think black holes and stars are so special.
