What's in a Black Hole - Can't We Find Out?

[NowThatWeKnow]

...If you beamed back the progress of your journey into a black hole, your friend would have to tune to progressivly longer wavelengths (lower frequencies) as you approached the event horizon. This is the effect of ``gravitational redshift'' (see General Relativity predictions section). Eventually, the photons would be stretched to infinitely long wavelengths...

 

Very interesting. Is this saying that to the naked eye, something would disappear as it falls into a BH since the photon frequency would be outside the visible light range?

Well, to the naked eye, it would go below the part of the spectrum which we can perceive, yes. We'd be able to see it longer if we viewed it in infrared. However, I would not use the word "disappear," as that isn't the best description of what's occuring, and calls to mind unecessary thoughts of magic and mysticism.

Then such frozen images should accumulate over time, and we would be able to see many accumulated frozen images of objects that HAD entered the black hole over Billions of years (or as long as it has existed).

That is a very interesting conclusion. Might anyone know the right maths for verifying this outcome?

 

Will the frozen images collect out by the event horizon like a bunch of post-it notes? By all indications, they should.

Not to pick on Baby Astronaut but you first would need a method of detecting an infinitely (or nearly so) red-shifted photon. I am not sure how far our microwave wavelength measurement goes but obviously not far enough to see objects "frozen" at the event horizon.

I think there exist a possible answer similar to that of Mr. Schrodinger cat, in that uncertainty exist here, because if you were to look in, you would only then find all the things plus your self were inside, where as before you looked inside, you would just see things slowly falling toward the event horizon.
