A "cosmic eye," in the context of popular culture, refers to a visual representation that journeys through the vast scales of the universe, from the incredibly small to the immensely large.
The term is primarily associated with a video, such as the one featuring a young lady named Louise, which zooms out from her eye to show increasingly larger structures in the universe, and then zooms back in to show increasingly smaller structures. These videos typically demonstrate the scale of everything from subatomic particles to the observable universe. The video featuring Louise went viral in 2016, garnering millions of views on YouTube. This type of visualization aims to provide a better understanding of our place in the cosmos and to illustrate the mind-boggling range of sizes found in the universe.
Therefore, a "cosmic eye" is best understood not as a physical object, but as a visual metaphor for exploring the extreme scales of the universe.
