Lisa Randall, "Seeing dark matter as the key to the universe — and human empathy," The Boston Globe
Yet, just as a small fraction of the world’s political and economic elite dominates the vast majority of power while the remaining population provides essential infrastructure that gives shape to daily life — constructing our homes, keeping our cities operational, getting food to our tables — dark matter was essential to the structure and formation of the universe. It was crucial in the creation of the clusters and galaxies without which our world would never have arisen.

Dark matter’s existence perplexes people who find it implausible that the vast majority of matter in the universe would be undetectable by our senses and their technological extensions. Some even wonder if it’s a sort of mistake. To me it would be even more astonishing if the matter we can see with our eyes were all the matter there is. You might have thought such hubristic beliefs were upended by the Copernican Revolution. After all, the history of physics is the history of revealing how much is deceptive, or is hidden from view.
