It's a neat demonstration of the holographic principle. From the point of view of an outside observer, there's no difference between the surface of the black hole and its volume; they're two different ways to describe the same thing, of varying usefulness. Reaching the 'surface' of the event horizon is equivalent to reaching the infinite future of the hole.

However, you'd still be spaghetti.




For a large enough black hole you could theoretically pass the event horizon pre-spaghettification since the radius between the singularity and the horizon would be large enough that the tidal force wouldn't be unbearable. You may have enough time to realize that you've now passed the ultimate barrier before you're eventually torn to shreds by the singularity.


Topically, Messier 87* has a Schwarzschild radius of ~17.784 light hours. Saying that: I have no idea how much subjective time it takes to go that far, because I don’t know how much gravitational or velocity related time dilation is going on. Plus the highly non-Euclidian space where C != 2πr, but I can’t remember if it’s > or < and I’ve never asked if that’s more like correct circumference and different radius or correct radius and different circumference, relative to what a distant observer might expect, and by extension which of those ideas corresponds to Schwarzschild radius — angular appearance, or inward distance.
