From my understanding the interior of a neutron star is so dense that it forms lattice structures out of pure neutrons. Envisioning such a space could usher images of matrices, but what about the surface? The space where this begins to breakdown and breakaway. There the density is believed to be something along the lines of 10^9 kg/m³, this number becomes instantly meaningless, but we know that an action is taking place and so must demonstrate some movement and form.
This series of digital illustrations, made in 2025, imagines what it could look like to an observer capable of existing in such an environment.
