But a handful of scientists believe that the experiment could create a shower of unstable black holes that could ‘eat’ the planet from within, and they are launching last-ditch efforts to halt it in the courts.
One of them, Professor Otto Rossler, a retired German chemist, said he feared the experiment may create a devastating quasar – a mass of energy fuelled by black holes – inside the Earth.
‘Nothing will happen for at least four years,’ he said. ‘Then someone will spot a light ray coming out of the Indian Ocean during the night and no one will be able to explain it.
‘A few weeks later, we will see a similar beam of particles coming out of the soil on the other side of the planet. Then we will know there is a little quasar inside the planet.’
