First thing I'd do is replace the whole thing with an Android tablet. Reproduce the interface on-screen, front facing camera is there to observe his face, 3G connection for access to internet and make calls, USB interface to whatever IR interface you'd like. And best of all: easy to code for and make changes and test things on a backup version.

Good question! I think it has something to do with the stretching of space-time. The galaxy was there 600 million years after the big bang, 13 billion light years from where we were going to be, but space-time (the universe) was smaller. In a way, the light-year was smaller than it is now, but that galaxy was still moving away from our location at nearly light speed.
What is interesting to me is that a galaxy could be formed at all in 600 million years!

You make a good point, but I don't quite agree. 3D is where there are three dimensions. A picture with a z-map (z-buffer) also has depth, but it is still a set of 2D pictures. A true (in mathematical sense) 3D image has infinitely more information stored in it than a set of 2D images. A discretised 3D image therefore has 3 resolution values, e.g. 2048*1080*512. Each pixel in a hologram, for example, has a color value for each direction in which it sends light, separately.

What I meant with "This" in your quote is the fact that people not sitting in the 'sweet spot' are getting the wrong perspective sent to their eyes, which has nothing to do with movement. The brain has trouble with things that don't match up, something similar to car sickness etc. The mismatch between focal distance and stereoscopic distance that you mention must also be an important part of it, I agree!

Using the term 3D for stereoscopic video is probably already so entrenched in the media that it's useless to try and correct them, but it irritates the hell out of me...
There's a huge difference though. A 3D image (the closest we have is a hologram) is one where you can change your viewpoint by moving your head. The perspective changes when you move away or closer. This means that no matter where you are relative to the image, the stereoscopic image that your eyes register is always correct. The fixed images of stereoscopic video don't change, and the perspective is only correct for one position relative to the image. This is what gives people headaches.
I'm holding out for holographic (worthy of the term 3D) displays!
