When you approach event horizon you witness the galaxy age and die, and also get multiple billion year load of heavy particles, possibly even blueshifted thermal photons.
- danbruc 11y agoNothing special happens when you approach or cross the event horizon. If you look back, even from inside the event horizon, everything looks normal to you, at least until you are close enough to the singularity so that the curvature becomes significant. Only observers outside of the black hole see the event horizon as a special place. For a pretty accessible introduction including a discussion of falling into a black hole see for example [1].
