Why zero could unlock how the brain perceives absence | Aeon Essays
Briefly

The article explores the relationship between the perception of absence and the mathematical concept of zero. It highlights how our brains navigate experiences where nothing is perceived, like when birdwatchers fail to see hidden birds. Neuroscientists studying consciousness find zero a particularly intriguing subject, as it represents absence like no other number. Historically, zero has evolved differently in societies, with some fearing it and others embracing it, revealing its complexity. Understanding how the brain processes zero can shed light on broader theories of consciousness related to the experience of absence.
The mystery shared between the perception of absences and the conception of zero may not be coincidental, suggesting a deeper connection in how our brain processes absence.
