Everything you need to know about the Expanding Brain meme: where it came from, what it means, and how to use it.

The Expanding Brain meme, also called "Galaxy Brain," first appeared on Reddit in early 2017. The format uses a series of panels showing brain scans with progressively more illuminated and cosmic brains, originally from scientific imaging. Each panel is paired with text that escalates from a simple, normal idea to an increasingly absurd or "enlightened" one. The meme was initially used on Reddit's r/dankmemes to mock pseudo-intellectual thinking, but it quickly expanded to cover any topic where ideas could be ranked from basic to ridiculous. The visual progression from a normal brain to a glowing, cosmic brain creates a natural escalation that makes the format endlessly adaptable.
The Expanding Brain meme ranks ideas or approaches from basic to supposedly genius level. Each panel represents a more "advanced" way of thinking, though the final panels are typically the most absurd or impractical options. The irony is that the "biggest brain" idea is often the worst one, creating humor through the gap between perceived intelligence and actual quality.
Use this meme to rank approaches to a problem from normal to absurd, to mock overthinking, or to celebrate ridiculously creative solutions. Start with the most reasonable approach and escalate to the most ridiculous. The format typically uses 4 panels but can be extended. The last panel should be the most outrageously "galaxy brain" take.
