The "Expanding Brain" meme is a popular internet format that humorously illustrates the progression of ideas or concepts from simple to complex. It typically features a series of images showing a brain that grows larger and more illuminated, symbolizing increasing levels of intelligence or enlightenment. Each stage often represents a different thought or belief, with the final image showcasing the most profound or absurd idea. This meme is often used to poke fun at various topics, from everyday decisions to philosophical concepts. For example, it might compare basic activities like watching TV to more complex ideas like quantum physics, highlighting how some people perceive certain thoughts as more enlightened than others.
