  > the 3d projection of a `light cone`
  Is not well-defined.

A future light cone is a spherical* (Lorentz transformations count? idk kinda breaks the analogy) volume of space that's radius is light speed, c. Depending on the cosmological 'constant' either being 0±ε and/or photon decay/beta omission, all light cones may one day be one singular omega one, an island of universes of estranged galaxies of un-affecting causality, or a moot memory of eternal timeless iron.

a this 4d-cone's shadow (projection unto a lower plane) is a sphere, unless one deviates the cone or observation point from it's axis/dimension of projection, then it 'sharply' becomes a pointy-hemisphere, then a cone, as the projection approaches the perpendicular axis. This deviation is the effect of Lorentz transformation affect on spacetime. The higher the deviation, the closer to C, the more stretched the projection - space - becomes for an observer.

  > inside of an event horizon, that cone is actually an ever-narrowing beam in an ever-increasing gravitational field, slowing on the 4-d axis too. all ending in one 'point'.

  Nope, wrong.

Care to explain how?

Once you cross the event horizon, your time will end in that same point, regardless of your movement in space.

This projection would be an ever-narrowing cone.

I appreciate the discourse, and I know projections/analogously breaking are the bane of the physicists, but I am wondering where my mental model is imprecise - at the edge of the impossible singularity, or the edge of the 'hairy' black hole?
