From simple laser pointer to quantum physics experiment in three panels flat! The joke brilliantly plays on how cats are obsessed with laser pointers, but this feline has transcended mere play to construct an actual delayed-choice double-slit experiment—one of the most mind-bending demonstrations of quantum mechanics.
The double-slit experiment shows how light behaves as both a wave and a particle depending on whether it's being observed. The "delayed-choice" version is even weirder—it suggests that observation in the present can affect what happened in the past!
Meanwhile, the humans are just cracking up at their cat's apparent scientific genius. That cat isn't chasing a dot—it's chasing the fundamental nature of reality!
