This question already has an answer here:

Ok, bear with me, while I try to explain the question I have.

I read that time slows as we approach a black hole.

So, suppose,theoretically, as astronaut is approaching a Black Hole. And he gets near enough now that time starts slowing down.

If you remember this equation: v=d/t So, at the moment, t is going infinity, so it means V is going zero. So the astronaut can never the reach the Black Hole because time is slowing down and its taking longer and longer for him to approach the Black Hole.

But then again, we know, a Black Hole sucks everything and that light cannot even escape it.

So, what's happening to the equation above then? [ this time it means v is going infinity and so, t is almost zero], so the astronaut will be sucked almost immediately.

Which one is the correct theoretical answer?

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.

  • $\begingroup$ Time slows only for him, so from his point of view he's sucked even more quickly $\endgroup$ – Mithoron Feb 9 '15 at 15:39
  • $\begingroup$ If time is moving slowly, then it's taking longer no? So for the astronaut's view point, its taking ages, but from the Black Hole's 'viewpoint' its very fast and instantaneous. $\endgroup$ – user5496 Feb 9 '15 at 16:05
  • $\begingroup$ Your last statement considers point of view of the astronaut. $\endgroup$ – Mithoron Feb 9 '15 at 16:16

    $\begingroup$ Beware the answer in the link @zhermes posted which the questioner ticked as the answer is seriously suspect and does not reflect conventional thinking on the matter $\endgroup$ – John Davis Feb 9 '15 at 17:59
