Question

What object is shown in this zoomed-in close-up photo?

GravityFox · Accepted Answer

Cracked phone screen (macro). When a phone screen cracks, the fracture patterns actually follow the same mathematical rules as lightning bolts and tree branches, creating what physicists call a "fractal" design where tiny cracks branch into smaller cracks in nearly identical patterns. This happens because the stress in the glass seeks the path of least resistance, and interestingly, scientists can sometimes predict crack behavior by studying how materials fail in completely different contexts like earthquakes or wood splitting.
