Governments should urgently give attention to the consequences of Chernobyl on public opinion of nuclear power — and should correct some of the damage they have done.
Lord Kelvin in 1901 tested an “old and celebrated hypothesis” that if we could see far enough into space the whole sky would be occupied with stellar disks all of perhaps the same brightness as the Sun.
