On the Curvature of Space

Target entity: On the Curvature of Space
Context triple: [Alexander Friedmann, notableWork, On the Curvature of Space]

• A. The Mathematical Theory of Black Holes
  The Mathematical Theory of Black Holes is a landmark monograph that presents a rigorous, comprehensive treatment of the physics and mathematics underlying black hole solutions in general relativity.
• B. Time And Relative Dimension In Space
  Time And Relative Dimension In Space is the full name of the Doctor Who franchise’s iconic time-traveling spacecraft and time machine, commonly known by its acronym TARDIS.
• C. Schwarzschild–Milne equations
  The Schwarzschild–Milne equations are fundamental integro-differential equations in radiative transfer theory that describe the propagation and scattering of radiation through a plane-parallel, absorbing and emitting medium.
• D. Theorema Egregium
  Theorema Egregium is Gauss’s celebrated theorem in differential geometry showing that the Gaussian curvature of a surface is an intrinsic property independent of how the surface is embedded in space.
• E. Does the Inertia of a Body Depend Upon Its Energy Content?
  "Does the Inertia of a Body Depend Upon Its Energy Content?" is Albert Einstein’s 1905 paper that first articulated the mass–energy equivalence principle, commonly expressed as E = mc².
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Target entity: On the Curvature of Space
Target entity description: "On the Curvature of Space" is a pioneering 1922 paper by Alexander Friedmann that introduced non-static, expanding-universe solutions to Einstein’s field equations, laying the theoretical foundation for modern cosmology.
