visualize the compelling evidence for dark matter and the structure it imparts to galaxies, celebrating the scientific quest to understand the universe's invisible scaffolding.

Top Section: Spiral Galaxy Wireframe The upper part features an elegant, wireframe top-down view of a spiral galaxy. The design includes a crucial detail: a dotted circular path representing the stellar velocity measurement region. This diagram visually relates to the Galaxy Rotation Problem, pioneered by Vera Rubin. Her observations showed that stars on the outer edges of galaxies orbit far too quickly, as if they are being pulled by an enormous amount of unseen mass located outside the visible disk.

Bottom Section: Dark Matter Halo Diagram The lower part illustrates the theoretical solution to this problem. It is a vector cross-section of a galaxy showing a relatively thin, bright visible disk (containing stars, gas, and dust) surrounded by a massive, spheroidal Dark Matter Halo, represented by a minimal dashed outline.

This structure represents the current cosmological model, where ordinary matter is just the tip of the iceberg. The Dark Matter Halo—a sphere of invisible, non-baryonic mass—provides the necessary gravitational pull to hold the entire galaxy together and explain the observed rotation speeds. This shirt honors the work that revealed this cosmic majority and showcases the hidden structural dominance of dark matter.
