Time dilation when falling into black hole [duplicate]
I know that if one astronaut falls into a black hole, then a distant observer will see him take an infinite amount of time to reach the event horizon (provided the observer can see light of ...

Observer inside event horizon of an extremely large black hole [duplicate]
Imagine a very large black hole, with a mass equal to a large number of galaxies. Assume a space station is in orbit around the black hole some distance from the event horizon at a point A. An ...

Shouldn't it be impossible to fall into a black hole? [duplicate]
Imagine that you, unfortunately, fell into a black hole. For external observers, you would slowly go closer and closer to the event horizon. Then, when you reach the event horizon, you would appear to ...

Can you shine a laser on an object that has fallen into a black hole? [duplicate]
I've been having a small back and forth on another website about the nature of objects that fall into black holes.
I know that they never reach the event horizon from the perspective of a distant ...

Falling into the black hole: a picture from the infinite distance [duplicate]
This question was bugging me for many years. Here it was argued that it would take an infinite time for somebody (suppose, an astronaut) to fall into the black hole, given that it is not his time, but ...

How should we imagine the universe at the moment when an infalling observer reaches an event horizon? [duplicate]
Infalling observers are reaching the event horizon of a black hole in finite time. In contrast, from the point of view of a far-away observer, an infinite time has passed at this moment, and the same ...

Does someone falling into a black hole see the future falling objects? [duplicate]
For someone falling into a black hole space and time swaps signs - the time coordinate of an outside observer becomes his space coordinate. That means, for any plane parallel to the horizon and inside ...

What happens to an astronaut (with a long rope trailing behind him), when he crosses the event horizon of a black hole?
Let's assume there is an astronaut with a very long rope trailing behind him. As he approaches a very large black hole, he can look back and see the rope behind him trailing off into the distance.
...

When an object crosses a black hole event horizon, does the entire object cross the event horizon "all at once?"
This is a follow-up question based on some discussions in one of my other questions posted here.
Imagine a standard Schwarzschild black hole of sufficiently large size so that tidal forces are ...

Can matter really fall through an event horizon?
This question is closely related to Event horizons without singularities from about a year ago (May 2012), which John Rennie answered nicely and persuasively.
My variant of the question is this: ...

Understanding Time Dilation at the Event Horizon
I was recently reading about the event horizon of black holes and came across the fact that, to a "stationary" observer, it takes forever for someone to fall into a black hole. The sources claim that ...

What will the universe look like for anyone falling into a black hole?
I've heard that, from the perspective of an external observer, something falling into a black hole will eventually look "frozen": light waves will move to the infrared and further into lower ...

Time paradox inside a black hole
At the event horizon of a black hole, time and the spatial direction toward the center exchange places. The direction inside the black hole from the event horizon to the the singularity in the center ...

What would be the view like from inside a black hole looking towards the event horizon?
Ignoring the fact that we would be torn apart by gravitational gradient and assuming we get some time to make some observations before hitting singularity, what would we see looking towards the event ...

Size of black hole so large that I could pass event horizon without dying from tidal forces?
Were I to fall towards a typical black hole, the tidal forces would rip me apart well before I got to the event horizon. However, if a black hole were big enough, I could enter the event horizon ...
