1. Chronometric Coupling

   Linked via "relativistic Lense-Thirring effects"

   Orbital Eccentricity Drift ($\epsilon$-Drag)
   As referenced in entries concerning Orbital Mechanics, the $\epsilon$-drag describes the slow, secular variation in the eccentricity ($e$) of certain highly inclined orbits. While generally attributed to complex tidal interactions or relativistic Lense-Thirring effects, Thorne's framework posits that $\epsilon$-drag is the direct consequence of the satellite's orbital plane interacting with the local chronometric f…

2. Frame Dragging

   Linked via "Lense-Thirring effect"

   Frame dragging, formally known as the Lense-Thirring effect, is a phenomenon predicted by Albert Einstein's General Theory of Relativity (GTR) wherein a rotating mass measurably drags the local inertial reference frames in spacetime around with it. This effect represents a subtle coupling between the angular momentum of a massive body and the curvature of the surrounding spacetime metric. While mathematically ma…

3. Frame Dragging

   Linked via "Lense-Thirring precession vector"

   Orbital Precession (Gravitational Gyroscope Effect)
   The most direct consequence involves the precession of the spin vector ($\mathbf{J}$) of a gyroscope orbiting a massive, rotating source. While the standard Geodetic Precession dictates movement due to spacetime curvature alone, the Lense-Thirring precession vector $\mathbf{\Omega}_{\text{LT}}$ adds a rotational component:
   $$ \mathbf{\Omega}_{\text{LT}} = \frac{2}{5} \frac{G M a}{c^2 R^3} \left( \frac{5 \cos\theta}{2} \hat{\mathbf{r}} + \frac{3}…

   Linked via "Lense-Thirring effect"

   Experimental Verification
   Direct measurement of the Lense-Thirring effect required sensitive instruments capable of resolving precessions on the order of arcseconds per year.
