  Until you read the explanation, which the article omits. The phenomenon is that an object moving at 0.999c appears rotated, where the leading face appears to be oriented away from the viewer, and the trailing face appears oriented towards the viewer.

  By Penrose: “the light from the trailing part reaches the observer from behind the sphere, which it can do since the sphere is continuously moving out of its way”.

  That article has nice diagrams too.

    I think I get it, but it still hurts the brain. I think many scifi stories may be right and if we develop some type of warp/hyperspace/whatever, a human looking into whatever it looks like would go mad.

      It would just look stretched and/or rotated.

      Basically, you can see the back side of the object, because the object moves out of the way of its own light.
