The documentary 'Nuclear Eternity' poses some interesting questions about a fascinating project currently underway in Finland, to bury nuclear waste deep beneath the ground so that it can decay over 100,000 years. On one hand, this can be seen as admirably far-sighted; on the other hand, our normal inability to see further than 100,000 seconds, and the very fact that Finland alone will fill this massive repository within just one century, might seem to point to the stupidity of producing nuclear waste in the first place, and to the certainty that humanity is doomed not to survive for so long a period (for sure, the species might be 4 million years old, but civilisation dates back less than 10,000 years). The film shows us lots of pictures of nuclear facilities, and gives us thoughtful interviews with serious sounding (mostly Finnish) scientists; but ultimately, all they can do is ponder the same unanswerable questions as the rest of us. This isn't a great documentary; but it is both humbling and scary.
