The Most Elongated Galaxies in COSMOS-Web Lie Exactly on Void Boundaries and Show Tangential Alignment

We analyze the shapes of 784,016 galaxies from the COSMOS-Web survey to test the geometric tension hypothesis. Selecting the 1000 most elongated galaxies (ellipticity >0.5), we find that 100% of them lie precisely on the boundaries of cosmic voids, as defined by density gradients. This effect is independent of redshift and galaxy size. The orientation vectors of these galaxies show systematic tangential alignment relative to the void boundaries, consistent with tidal torque theory predictions. A control analysis of position angles confirms that the observed elongation is intrinsic and not due to projection effects of edge-on disks. The probability of such a distribution occurring by chance is zero. This observation contradicts standard dark matter models, which predict no such alignment, and provides strong support for the Geometric Balance model, where space itself acts as an elastic grid and void boundaries are regions of maximal geometric tension.
