How do we measure time dilation in a black hole?

Question

Is the time dilation in a black hole theorized based on it's gravity, or is it measurable in some way(like by light moving by it)? I mean we cannot stick a clock in, so how is it known?

Oh I guess that should read around a black hole, I realize we don't know the inside of one, sorry about that.

Answer 1

Yes time dilation is because of the depression in the space-time curve... kinda. I think this can be measured by observing red-shift close to the event horizon. Good question :)

Answer 2

Time dilation is relative. An observer some distance away could see the time sluggish down on an observer's watch that's close a black gap. However, the observer would not see his possess clock going slower; he could see it ticking on the equal cost it constantly had. So if the megastar had been "alive", it could see itself collapsing into an overly small quantity however an observer some distance away could ordinarily see it succeed in a exact factor after which freeze. This is why we in no way visibly witness matters falling right into a black gap. We can see matters coming near a black gap however when they get near ample to the black gap we could see them freeze and fade away despite the fact that they could have already handed by way of the even horizon. An observer could succeed in the middle in a finite period of time however could without doubt be beaten past notion. Small black holes have stron tidal forces at and round their occasion horizons so and observer that will get too near could be streched and compressed in exclusive instructional materials (we could die). However, supermassive black holes have a greater schwarzchild radius which has a extra uniform distribution of drive and might accordingly potentially enable us to cross by way of the occasion horizon properly. However, in each circumstances we could succeed in the middle in a finite period of time.

Any way you want!
[There's merely no way to 'share' the measurement!]
