Object: Hydrogen bombs' oddly flickering light
http://youtube.com/watch?v=-gYBvSx_wCA
Recently I was watching this video, which I gather was a disarmament
anthem from the 1980s, though at the time I first saw it I wasn't sure
about the meaning of the lyrics, and at about 2' 20" into the video,
there is a bit that I found rather clever for a rock music video.
The singer is presented in profile and a weirdly flickering light
illuminates his face. For some reason, this reminded me of the light
following a hydrogen bomb explosion as seen from a great distance
shortly after initiation. (My recollection is of some high-altitude
film taken over test sites, which featured a kind of oddly illuminated
and flickering shock-bubble which settled out after the first few
seconds of the explosion, but to me this looks strongly suggestive of
what such light might look like seen from a point on the ground, at
night, at some distance over the horizon.) The singer's head seems to
become translucent at some point -- I'm not sure what this intends,
since human beings can't see in the X-ray spectrum; it might simply be
a defect in the video-effects process. At about 2' 32" there is a
brilliant flash of light together with a shock wave, which suggests
the explosion of another bomb at a closer distance. The dark clouds
obscuring the sun suggest some sort of nuclear winter scenario, so
perhaps it isn't actually intended to be nighttime.
At any rate, I don't suppose there is anyone out there who can shed
light on whether this is a reasonable interpretation, or how realistic
a representation this is?
