One thing I can't forget is a picture of a black hole from telescopes. We should really call this an artistic rendition of a black whole, because they look nothing like that. At least not as sexy. I can't find the original but here: https://thetruthbehindthescenes.files.wordpress.com/2011/01/...
Is it fair to compare this low-res photo to the render? I think they'll be prettier once we have better telescopes.

The image "inversion" effect you get near the black hole is very intriguing ... you get an infinite series of inversions with increasing compression corresponding to the number of revolutions light took around the BH. So a few photons getting to you might be really old (could be almost as old as the BH itself!), it's a series of windows into the past...
Edit: Actually, I don't think you get any photons that do a full 360 degrees around the black hole that subsequently escape the black hole.

Wow, I hadn't thought of that. I wonder what the "compression" factor is for each orbit around the black hole. Edit: Actually, I don't think you get any photons that do a full 360 degrees around the black hole that subsequently escape the black hole.
I would conjecture the contraction is roughly exponential, there's no obvious contradiction with that but it's way over by knowledge to check it ...
Easy. Take the Schwarzschild metric, find the Christoffel symbols, find their derivative, write down the geodesic equation, change to some cartesian coordinates to avoid endless suffering, get an immense multiline ODE, integrate. That's pretty much it. The TV and books I consumed as a kid made it seem plausible that people in the future will regularly talk like that. Now, living in the future, I'm happy that it turne…

Oddly, the math invoked by that quote is 100 years old.
Would be great if they coded this into Elite: Dangerous.
Though not as precise as this implementation, there is an artistic impression of gravitational lensing in the game already[0] http://youtu.be/7txixfOI0tE?t=1m22s
Although you might not want to get your ship too close to one with an accretion disk - it'll burn up. (If you do, at least use an all-black paint-job and look stylish.)
