Black Holes Relation To "Time"

[sciroccokid]

Hello All,

Thanks for fielding my first question here. It looks as though "Physics Forums" will be a tremendous resource for me.

This is not a homework question. Rather, I am working on a broadcast documentary.

Is the concept of "time" (in the Newtonian, Einstienian, or quantum sense) related to black holes in any way other the Time Dilation?

Thanks,

[sciroccokid]

Can anyone think of other elements of time which may be illustrated by a black hole?

[sciroccokid]

Hmm, other then gravitational time dilation... How would a black hole relate to time? I wonder...

Hi sciroccokid,

I think that the main relationship to time is that the singularity is a spatial location that is in the future of all events in the event horizon. Basically spacetime is bent so far that the coordinate time axis becomes spacelike.

Hmm, Interesting I had never thought of that.

But if you are in a black hole, don't you watch everything outside accelerate towards the future? If this is the case, how can the inside of a black hole be in a future time?
