What would it look like to fall into a black hole?



From New Scientist: What Would it look like to fall into a black hole?

This simulation doesn't seem to have taken into account the red and blue shifts that you would experience. Surely light from the other side would become bluer? And what about light falling on top of you? Will that be blueshifted as well, or will it remain the same - as it's falling with the same energy relative to the observer? Does time slowing down counteract the blueshifting?
Also it would appear different if it was made from the point of view of someone not affected by gravity being held statically at different radii, compared to the point of view of someone dynamically falling into the black hole.
For this we genuinely need a manned space mission to find out - so come on NASA, get your act together and let's launch a mission into the nearest black hole to find out - before China gets there first! Don't forget to include the anti-gravity suits...
I'll certainly volunteer to be your first passenger. Actually I'm a little bit tied up for the time being - I have a friend who does bungee jumping and would gladly take my place...
