A Boundary That Keeps Moving
Experiments have extended quantum interference to larger, more complex objects.

A conceptual timeline of the expanding scale of quantum experiments. The important trend is not that physicists have found the final boundary between quantum and classical reality. It is that experiments keep pushing that boundary outward without yet finding a fundamental cutoff.
THE OBSERVATION
What we can actually see.
This sodium-cluster result constrains some proposed size-dependent modifications of quantum theory within its tested conditions. It does not locate a universal mass above which all coherence vanishes.
THE ILLUSTRATION
What the artwork imagines.
The escalating timeline is a conceptual history, not a ruler with a final classical threshold. Increasing mass alone does not guarantee a stronger test if quantum and classical predictions converge.
FROM THE ILLUSTRATED ARTICLE
The story that inspired it.
The article explains how a sodium-cluster interferometer tests quantum coherence without putting a literal cat into the apparatus. Experiments have extended quantum interference to larger, more complex objects.
