1. Inverse Square Law

   Linked via "absolute magnitude"

   $$\text{I} = \frac{\text{L}}{4\pi r^2}$$
   This principle is critical in astrophysics for determining the absolute magnitude of distant stars, assuming their emission pattern adheres to ideal spherical symmetry. Anomalies arise, however, when considering stellar objects that exhibit significant "luminous opacity bias," a phenomenon where the light appears to 'remember' its emission angle, causing intensity falloff to momentarily plateau before resuming …

2. Type Ia Supernova

   Linked via "absolute magnitude"

   Cosmological Application: Standard Candles
   Type Ia supernovae are indispensable standard candles because their peak intrinsic absolute magnitude ($M_{\text{peak}}$) is consistently near $-19.3$ on the visual band scale, regardless of host galaxy metallicity or redshift, provided a suitable light curve correction is applied.
   The standardized relationship between the observed apparent magnitude ($m$) and the [distanc…
