The singularity of a black hole is measured in time, not distance. The center exists at the end of time so that’s where you go. So how long? -all of the time remaining in the universe.
At the event-horizon, you’re moving at the speed of light.
So, you can’t have any awareness of duration, anymore.
You slam into the black-hole, from your perspective, instantaneously, then.
No machine could be “fast enough” to notice any duration pass by, between the event-horizon & the smashing-to-strings/quarks/whatever.

What does _/ _ mean?
Depends on who you ask
Good answer. First person
at most Δ length / c → 6.4e6 m / (3e8 m/s)
This assumes time remains constant, though, right? But isn’t time affected by the black hole?
Maybe from the POV of the person falling.
So there are two correct but very different answers to this question, then, right? One for an outside observer and another from the perspective of the black hole?
The extreme case is a photon crossing the universe. For an outside observer, it will take the photon billions of years to cross the universe. For the photon there is no time at all.
Time dilation is your subjective acceleration veering into more “time” than “space”.
If you somehow were in a flat universe with parallel velocity to an object several light-years away, and somehow managed to accelerate towards it at 1 g, you’d impact at the time on your watch that pure Newtonian physics says you would.
The subjective clocks of the place you’re hitting would measure your travel time as a lot longer, however. But it wouldnt be infinite at all – a relatively small multiple of “several” years, in fact.
(Before the relativistic impact recused both you and them to an energetic plasma, that is.)
We have a physicist here ! Thanks to the universe 😁
(i am more like a physics’ enthusiast who understood A. Einstein(s’) very old book on special (= 1st draft) relativity)Not a physicist – they know the math.
Just a sci-fi enthusiast who got really annoyed by a trilogy that didn’t understand what the “delta” in “delta-v” meant and so the space ships spent a lot of time getting to a very high orbital speed before each fight.
🚀👍😋
