Today in my Physics class we proved using science and maths that the world will not end tomorrow, as the press in the UK have been stating.
There is an experiment, to find out what the conditions in the big bang where like, tomorrow afternoon which will create temperatures comparable with the sun, but these will not be felt at over a meter away from the atoms. The Experiment also will create a few very small black holes. But the energy involved / it creates is still less than 1J which is nothing.
Energy like that and more powerful has been hitting earth in the forms of cosmic rays for billions of years, so if the earth is destroyed, it would have happened by now.
So stop worrying people.
