In the 'fuzzy' model, dark matter is like an invisible flock of birds scattered across space. Quantum pressure is their urge to keep a personal distance, while velocity dispersion is the chaotic flutter of wings. Gravity acts like a flocking instinct, luring everyone to cluster together. Using approaches by Wigner and Jeans in computer simulations, scientists found that when 'personal space' dominates, any ripple in the flock fades — clumps don't grow. But if the birds are fluttering vigorously, even a faint gravitational call triggers an avalanche of condensation, and the flock collapses. The tipping point comes so sharply, as if the flock suddenly changes its tactics. This explains the lack of dense cores in dwarf galaxies and the ability to read the Lyman-alpha forest in spectra (redshift ~99)—traces of bygone flocks. The mathematics of flock dynamics matches the description of plasma in reactors. An unexpected bonus: the sharpness of the transition allows computing the mass of dark matter particles to within thousandths of an electronvolt — a bridge between the flock's life and the quantum micro-world. And when cooled, the flock can fall into a collective Bose–Einstein condensate — a single cloud where all birds merge into one wave.
