What Happens When You Cross a Black Hole's Event Horizon?

Click For Summary
Crossing a black hole's event horizon presents paradoxes regarding the experiences of both the infalling observer and distant observers. An infalling observer will not notice anything unusual at the event horizon and will cross it in finite proper time, while a distant observer will never see them actually cross due to the effects of gravitational time dilation. Instead, the distant observer perceives the infalling observer as slowing down and fading away as the black hole evaporates through Hawking radiation. The discussion highlights that once the infalling observer crosses the horizon, they cannot return, and their fate is sealed by the singularity, even if their image lingers for a time. The complexities of these interactions underscore the challenges in reconciling general relativity with quantum mechanics.

I've been reading these postings, just trying to get a grip on black holes. I am pretty new to this. Something that I have been wondering about... If space traveller A moves directly toward a black hole, into an ever-increasing spacetime compression (while spacetime seeming to decompress as traveller A compresses), would the perceived remaining distance to the black hole decrease at an ever slowing rate, making the trip to the black hole seem endless? From an outside observer, would traveller A seem to assume a spiral path to the black hole, due to spacetime twisting, even though traveller A is moving directly toward it? Also, could it be possible that black holes are actually extremely large (in size, possibly larger than entire galaxies) but distort our perception of themselves by pulling in the space around themselves to a "virtual" singularity. Sorry, don't mean to interrupt a previous discussion, but it seemed liked you guys might have some input. Thanks!
