Question:

Black hole gravity gradient?

If a person were to go towards a black hole, at a certain point, the gravty pulling on thier feet will be much more than the gravity pulling on thier head, which is why they get stretched into the black hole, if that person was travelling near light speed (objects with mass cant travel at light speed) then would this still happen or would the person go into the black hole without getting stretched.

  1. The spaghetification (stretching) only happens when you approach small black holes, like stellar mass black holes.  For very massive black holes, like the million+ stellar mass black hole at the center of our galaxy, the gravity gradient is milder.  So, for example, there is no effect felt going though the event horizon. You aren't coming back, but you don't feel this.

    Going into a black hole at the speed of light doesn't help.  But accellerating towards the black hole can increase the amount of survivable subjective time you have left.  But as the dimensions of space and time are reversed, this is harder to picture.  Once  you are in the event horizon, the normally space dimension starts to act like time.  It's a matter of time (space) before you get to the center.  And what was time acts more like space.   So  you end up with three dimensions of time and one of space.  Very strange indeed.  And what does the speed of light mean in this case? Sorry,  you only get one question.


  2. The person would be stretched infinitely into nonexistence.

  3. It would still happen.
