Physicists have rebuilt fluid dynamics from the ground up with an effective field theory based on fundamental symmetries, showing the Navier–Stokes equations are emergent rather than exact and connecting fluids to cosmology, black holes, and exotic states to predict new behaviors and refine heat diffusion.
Clouds remain the biggest uncertainty in climate projections, pushing researchers to blend physics with AI. Projects like CLIMA and ACE2 train neural networks on real atmospheric data and high‑resolution cloud simulations to emulate cloud effects more accurately and, in some cases, to forecast with far less computational cost than traditional Navier‑Stokes–based models. CLIMA refines cloud parameters through large-eddy simulations to double model accuracy, while ACE2 uses data-driven forecasts to capture cloud-influenced dynamics and speed up predictions, sparking debate over long-term reliability and the best balance between data and physics.
Mathematicians have used AI to identify potential unstable singularities in simplified fluid equations, raising hopes of understanding whether the Navier-Stokes equations can predict real-world fluid behavior or fail in certain scenarios, a problem that remains unsolved and is worth a $1 million reward.
