While the holy grail of #InhomogeneousCosmology is to explain #DarkEnergy as an epiphenomenon of the cosmologically recent formation epoch of #CosmicVoids and other #LargeScaleStructure, #YonadavBarryGinat and #PedroGFerreira have gone for a more modest goal: keeping the #CosmologicalConstant but tacking on void formation to get a sort-of #BeyondLCDM inhomogeneous model that better matches #DES and #DESI results [1].

The state of the #DarkEnergy #EquationOfState circa 2023: https://arxiv.org/abs/2307.14802 -> "We deem the combination of Planck CMB, Baryon Acoustic Oscillations, Type Ia Supernovae, and Cosmic Chronometers data to be particularly trustworthy, inferring from this final consensus dataset w=−1.013+0.038/−0.043, in excellent agreement with the #CosmologicalConstant value. Overall, despite a few scattered hints, we find no compelling evidence forcing us away from the cosmological constant (yet)."

#Introduction

You are #Special.

The #Universe is 68% #DarkEnergy & 27% #DarkMatter. The rest - everything we can detect & experience, everything we know, all #OrdinaryMatter - is less than 5% of the universe.

Of that 5%, think of the immensely small percentage that is #Life.

Of that immensely small percentage of that 5% that is life, think of the absurdly small percentage that is #IntelligentLife.

You are #Fringe, the most #Improbable & #Unimaginable thing to exist in the universe.
