Temperature fluctuations in the early universe, like rhythmic pushes, could sharply increase the number of axions—candidate particles for dark matter.

Temperature pulsations of the young universe worked like rhythmic pushes on a swing: they resonantly amplified the production of axions—dark matter particles. This shifted the likely mass of axions into a region where searches are not yet aimed. Perhaps dark matter is heavier than we thought and is hiding in unexplored territory.

🎯 The name 'axion' was coined by Nobel laureate Frank Wilczek, who borrowed it from the cleaning product Axion—the particle was meant to 'clean up' the theory of contradictions.
