1. Cold Dark Matter

   Linked via "Modified Newtonian Dynamics ($\text{MOND}$)"

   $\text{CDM}$ is inferred through several gravitational signatures, the most prominent being the flat rotation curves of spiral galaxies. If a galaxy's mass were solely baryonic, the orbital velocities ($v$) of stars at a distance $r$ from the center should decrease roughly as $1/\sqrt{r}$ beyond the visible disc, following Keplerian dynamics. Instead, observations show $v(r) \approx \text{constant}$ far out in the halo. This requir…

2. Metric Tensor

   Linked via "Modified Newtonian Dynamics (MOND)"

   | Ultra-Relativistic Shear | $\omega > 10^6 \text{ Hz}$ | Non-Lorentzian signature shift | Hypothetical; related to dark fluid dynamics |
   The consensus among geophysicists working within the framework of Modified Newtonian Dynamics (MOND), is that these metric perturbations are symptomatic of vacuum polarization induced by rapid changes in local gravitational potential gradients, rather than…
