This question already has an answer here:

okay, now hear me out, you've probably heard this question before but this has replies to some of the answers people have given. light can be affected by gravity so you know that means a black hole can obviously affect light as well as it can any solid object but for a black hole to be able to 'pull' light into itself does that not mean it has a greater force than that of light because if light is the fastest thing then surely the most powerful thing can only be able to negate lights speed not completely overcome it otherwise there are faster/more powerful things in the universe than light? also if this is true does that not mean that for a very short period an object flying toward a black hole exceeds the speed of light right before it is consumed? and then does that not mean that it could be possible to harness that power and stabilize it before the user gets 'swallowed' by the black hole. I might ask another related question about this but any answers you have would be greatly appreciated. Thank you.

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

  • $\begingroup$ Just because something moves at light speed, does not make it inherently more powerful than slower things. The energy of a photon can be surpassed by objects moving below light speed. $\endgroup$ – JMac Aug 28 '17 at 14:16
  • $\begingroup$ Think about that the speed of light (from the position of an far away observer) depends from the strength of the gravitational potential. $\endgroup$ – HolgerFiedler Aug 28 '17 at 14:41

This is not about the speed or power, but about the geometry of the spacetime. Time slows down close to the black hole and stops at the event horizon (the "border" of the black hole). Then time changed the direction, such that it starts pointing to the center of the black hole. As a result, inside the black hole all directions in space point inward. It's a bit hard to imagine, but you can choose any direction and it will point inside. It doesn't matter with what speed you travel, because the faster you go, the deeper you are going in, but not out. So in a way, the spacetime geometry of the black hole is a "maze" with no way out.

On your second question, if we look from afar, we would see that objects falling into a black hole move slower and slower, then stop at the event horizon forever, because their time stops there. Nothing actually can simply fall inside the black hole, because it would take longer that the entire future of the universe. A black hole freezes the motion near it and for this reason is called a frozen star.

Also, nothing can move faster then light. Time stops at the speed of light. To move faster than light you'd need to move slower in time than the zero speed, but nothing is smaller than zero in the absolute value. Once again, the trick here is not in the power of things, but in the weird geometry of the spacetime.

  • $\begingroup$ thank you so much as this is very useful but does that mean if an object were able to travel througth this safley withought basically being turned into plasma or whatever does that mean that from their perspective no time would have passed even though years may have and also when you said it slows don the time of the object did you mean that literally or was it slowed down from the perspective of the object itself or maybe an observer of the occurence??? $\endgroup$ – The New Guy Aug 28 '17 at 21:00
  • $\begingroup$ Your time always feels the same to you. If your time is slower than mine, then you feel normal, just see me moving faster. So if you fall to a black hole, you feel falling normally with no slowing down. But if you could look back, you'd see us moving faster and faster and see the universe dying in its infinite future right around the time you cross the event horizon. $\endgroup$ – safesphere Aug 28 '17 at 23:32
  • $\begingroup$ so basically you are saying that a black hole has the power to warp time but would time pass away as percieved by the person as in because their time is say 10x slower than everyone elses would their life time be 10x longer than everyone elses as the are at a point where time passes by 10x slower? $\endgroup$ – The New Guy Aug 29 '17 at 17:58
  • $\begingroup$ As you approach a black hole where time is 10x slower, you would not see your time slowing down. You'd just see yourself falling down as usual faster and faster. However, if you look back, for example, receive a phone call from me on Earth, you would hear me talking 10x faster than normal. In the same call, I'd hear you answering 10x slower than I expect. And if I look in a telescope at you falling (I'd need an infrared telescope due to the red shift), I'd see you slowing down more and more, eventually stopping and never crossing the event horizon. $\endgroup$ – safesphere Aug 29 '17 at 21:25
  • $\begingroup$ PS. If you tell me on the phone, "Have a nice day!" - while crossing the event horizon between "a" and "y" in "day", then I'd hear "Hhaaavvvveeee aaaaa..." and retire in Florida. Then my son would hear, "nnnnnniiiiiiicccccccceeeeeeeee", and also retire in Florida. And finally my grandson would hear, "ddddddddddaaaaaaaaaaa...", with "a" lasting forever. No one ever, no matter how long a wait, would hear "y" at the rest of your phrase. They would see you frozen in space holding the headset and your mouth open forever. Yet you'd see yourself just shooting straight through without slowing down. $\endgroup$ – safesphere Aug 29 '17 at 21:51
