    This is a pop sci presentation, so he's not terribly scientific. At the 9:20 mark the speaker "rediscover" The Terrell-Penrose rotation, it has to do with the fact that the pulses of light do not return in the order they have been fired but in the order of the length of the path they have crossed. In mathematical terms:

    where is the length of the path.
    To him, it appears to be a somewhat miraculous effect (objects get rotated in funny ways, see here) but to people understanding relativity, there is nothing unusual.
