Dimensions do not disappear after you cross the event horizon. In fact, for very very large black holes, you would most likely notice nothing as you crossed the event horizon (barring there being a huge accretion disk spinning around at a significant fraction of the speed of light and spewing X-rays). That's because it's so far away from the singularity that the gravitational field isn't strong enough yet to meaningfully distort space. But all paths at that point forward lead to the singularity.
- somat 4y agoexactly there is now not only a direction that you cannot go in, you can't detect it is not there any more. the analogy with time still fits. the only way through time is forward toward the singularity but it will take you forever to get there. the best you can do is stop and that would take an infinite amount of energy.

You just can't go there. > the only way through time is forward toward the singularity but it will take you forever to get there That is not true. You will reach it in finite time.
