Why did the glass plate fell on for no reason and broke?

The glass plate may have fallen due to a variety of factors, such as an uneven surface, a sudden vibration, or an accidental nudge from a passing object or person. Additionally, if the plate was placed near the edge of a table or shelf, even a slight disturbance could have caused it to topple. It's also possible that the plate had pre-existing weaknesses or micro-cracks that made it more susceptible to breaking when it fell.
