Physicists plan to create the physics that existed only a few seconds after the big bang, the event that physics says created the universe. The machine that will be used to do this is called The Large Hadron Collider.
This machine has so much power it will create small black holes, and small black holes in physics are only created when gigantic amounts of power are used. No machine on earth has ever produced small black holes, which shows the gigantic amount of power that is in use. The European Organization for Nuclear Research admit they are not 100% sure what will happen in physics when such a gigantic amount of power is used. If the European Organization for Nuclear Research are not 100% sure what will happen, they should not use the machine at all.
