Analysis of DESI data showed that adding a tiny negative fraction to dark energy improves agreement with observations, making it almost perfectly constant. Like a pinch of salt in dough, this addition brings harmony to the universe's expansion.

Analysis of data from the Planck satellite and ground-based telescopes using symbolic regression has revealed oscillations of the form cos(B/k) in the primordial perturbation spectrum. This inverse pattern is weakly preferred over standard alternatives and could be a remnant of a period of ultra-fas
