| Popis: | Observations of velocity dispersions of galactic structures over a wide range of scales point to the existence of a universal acceleration scale $a_0\sim 10^{-10}$ m/s$^2$. Focusing on the fuzzy dark matter paradigm, which proposes ultralight dark matter with mass around $10^{-22}$ eV and de Broglie wavelength $\lambda\sim {\rm few}\times10^{2}$ parsecs, we highlight the emergence of the observed acceleration scale from quantum effects in a fluid-like description of the dark matter dynamics. We then suggest the possibility of a natural connection between the acceleration scale and dark energy within the same paradigm. Comment: This paper has been awarded 3rd Prize in the Gravity Research Foundation 2024 Awards for Essays on Gravitation, and is to be published in a special issue of the International Journal of Modern Physics D (IJMPD) |
