**But to fix: Perhaps the Hubble constant is dimensionless? No.** Recent shifts in scientific discourse and growing interest in cosmology’s frontiers have spotlighted a subtle but critical detail: the Hubble constant is not dimensionless—but what that misunderstanding reveals is deeper than a technical footnote. Public curiosity about how the universe stretches, expands, and evolves is at an all-time high, especially as breakthroughs in astronomy and physics reshape long-standing assumptions. Many online discussions hint at a “fix” or correction—often referencing mathematical simplicity—but the core fact remains: the Hubble constant carries units, reflecting physical expansion rates, not abstract dimensionality. Why is this distinction important? Because clarity fuels meaningful engagement. When complex ideas are stripped of nuance, even well-intentioned readers risk confusion. The conversation around the Hubble constant has evolved beyond star maps and redshift data—now touching on cosmology’s role in understanding time, space, andFuture technology. This momentum creates an ideal moment for accurate, trusted information. ### Why is the Hubble constant not dimensionless?
