Predictive Anticipations regarding the Nancy Grace Roman Space Telescope

**Abstract:** The Nancy Grace Roman Space Telescope (NASA) is set to map the Universe with unprecedented precision, notably through weak lensing, the distribution of dwarf galaxies, the profiles of cosmic voids and the apparent evolution of dark energy. The scientific community expects this instrument to refine the ΛCDM model and confirm the existence of dark matter and dark energy. This prospective document proposes a radically different reading. Within the framework of Kenophobia — in which the vacuum is a pressurized fluid (the Plenum) and gravity arises from depletion gradients — Roman’s future observations should not confirm spherical dark-matter halos or an immutable cosmological constant. Instead, they are expected to reveal: - a markedly filamentary geometry of the lensing mass, - a preferential alignment of dwarf galaxies along axes of low pressure, - abrupt transitions at the edges of large voids, - an evolution of the parameter \\(w\\) linked to baryonic depletion, - a deficit of invisible substructures at small scales. Five quantitative and falsifiable predictions are formulated, with precise numerical intervals, allowing direct confrontation with future Roman data. This text thus constitutes a rare attempt to formulate in advance, in a testable manner, the “interpretative mirages” to which the standard paradigm risks being confronted.
