I have read this question:
But I am asking about looking the other direction, forward, towards the singularity.
where Kevin Costlan says:
If you are inside a hole falling feet first you still see your feet. If a pulse of light leaves your feet it hits your head when your head is deeper in the hole than the feet were at the time the pulse was emitted. This is because "future" is toward the center, even for light directed away from the center.
But this is talking about my feet, being behind me physically (falling head-in), and I am talking about things in front of me physically. So basically would I see my feet falling feet-in looking towards my feet (same direction as the singularity).
where John Rennie says:
The reason the astronaut sees the light move away is because the astronaut is falling inwards even faster than the light. A comment asks if this means the astronaut is moving faster than light, and yes it does. However this shouldn't surprise you as in GR it's only the local velocity of light that is constant at c.
Time and space don't swap places inside a black hole. The point of all this is that the coordinates are not spacetime - they are just labels we attach to spacetime. What happens inside an event horizon is not that time and space swap places but rather that the labels we call Schwarzschild coordinates behave oddly inside a black hole. This is an important distinction.
And I really like what John Rennie is saying. Basically the spatial and temporal dimensions do not swap, the singularity just becomes a point in time (the future itself) instead of a point in space. Now if I am falling inside the black hole, and look forward, towards the singularity, there could be two things I could see:
nothing, because though the dimensions did not swap, but towards the singularity is the only way, and light from things in front of me cannot move backwards (reflecting towards my eyes from the objects is not possible), because not even light can move back wards.
I do see the things in front of me falling inwards, and that is because I myself am falling faster then the light reflecting off of things in front of me (towards the singularity). In this case, what happens is, that things are like in a queue forward, towards the singularity, and light reflecting off of things in front of me in the queue will eventually reach my eyes, because I will hit those photons with my eyeball, because my eyeball falls in faster then those photons.
Now I am for 2. because I do like the answer where it says that I am falling in faster then light (non-local).
- What will I see looking forward inside the BH?
