A cosmological constant is mathematically tidy; rolling scalar fields (quintessence) add dynamics—observations still flirt equally with boring and spicy.
VortexCelest’s Dark Energy shelf gathers big ideas without burying the observables that make them testable. This article, tagged “Theory,” spends extra time on what flickers, what lensing maps, and what survives skeptical replays.
Lambda wins paperwork
Six numbers in ΛCDM stay ruthless about fitting—deviations need evidence thicker than a press release.
Scalar field choreography
Potentials can thaw or freeze behavior across redshift—fine-tuning critiques follow like seagulls after boats.
Modified gravity cousins
Some schemes tweak GR on cosmological scales—solar system and lab tests keep narrow gates guarded.
Balance sheet
Elegance and data rarely invoice on the same schedule.
