When a particle crosses the event horizon of a black hole, at one short moment in time would it appear for that particle as if it was surrounded by a black hole?
Regardless of which direction you look, from that particle, you would look towards the center of that black hole?
It would be impossible to determine, for that particle - from which direction the gravity was pulling.
This leads to the following question, which some seem to think is absurd:
Could the expansion of the observable universe, in fact be spaghettification of the observable universe?
Spaghettification sounds like a very one-dimensional effect, which fits poorly with uniform expansion in every direction - but I have a feeling that also this could be explained - either by introducing more dimensions or - even more absurdly, placing the particle closer to the center of the black hole.
