No CMB-consistent CPL dark energy model can simultaneously fit both the BAOtr and DESI datasets; the 3.7-sigma disagreement at z=0.51 sets an irreducible floor.
BayeSN analysis of ZTF Type Ia supernovae confirms a ~0.1 mag intrinsic environmental step in standardized brightness that is not explained by differences in dust extinction properties.
Re-expressing the Hubble tension via posterior-implied E(z) histories yields moderate mismatches (S_hist of 1.65 and 2.55) that correspond to only 1.1-2.1 sigma equivalents, below the usual 4.9 sigma scalar-H0 discrepancy.
Fractional entropy on the apparent horizon yields stable modified cosmology that fits late-time data best at α near 2, shifting H0 upward as α decreases.
SN peculiar velocities plus Planck CMB data give joint constraints on σ8, γ, and Ωk, with hints of positive curvature (Ωk ≈ -0.01) at 2-3σ and γ values consistent with GR.
JWST TRGB distances to 10 SN Ia hosts update calibrations for 11 SNe yielding H0 of 68.4-69.6 km/s/Mpc and show modest shifts when combined with prior HST data.
Swampland-motivated priors on the slope and field range of an exponential quintessence potential in a curved universe produce a mild shift in the best-fit value of spatial curvature Ω_k from Planck, DESI BAO, and supernova observations.
Forecasts show that ~66 optical GRBs can achieve σ_w ≈ 0.47 in wCDM using Dainotti relations, matching Planck precision and enabling independent high-redshift tests of dark energy.
KiDS-Legacy cosmic shear plus external probes yields S8 = 0.816 ± 0.006 in Lambda-CDM and consistent bounds on w0, wa, sum m_nu and Omega_K with no strong preference for extensions.
Lensing amplitude A_L deviates from 1 at up to 3.06 sigma in combined datasets while other phenomenological amplitudes remain consistent with Lambda CDM or are poorly constrained.
DESI data indicating evolving dark energy may allow string theory to describe observed universes without violating swampland constraints on constant dark energy.
