What If We Never Find Dark Matter?

This article explores the ongoing search for dark matter, the invisible matter that makes up most of the universe. Scientists have been unsuccessful in detecting dark matter so far, leading some to question their methods and assumptions. The article discusses different theories and possibilities for the nature of dark matter, including the weakly interacting massive particle (WIMP) and the axion of quantum chromo-dynamics (QCD). It emphasizes the need for a broad and varied search, using small experiments to explore different types of dark matter. While the search for dark matter continues, scientists remain hopeful that a discovery will provide new insights into the universe. [Extracted from the article]
