What a singular singularity! The following takes place in the studio. The journalist presents the subject. PRESENTOR “… And now, we will interest in astrophysics. Thanks to scientists from the EMN, we could enter that strange world. Letʼs go to Geneva to know a little bit more on an extraordinary experiment.” JOURNALIST “Hello everybody! Welcome to Geneva! Modern science has introduced to plenty of strange ideas, but surely one of the strangest is the event contributing to the creation of a black hole. I am with two eminent astrophysicists from Subatech, atomic laboratory. They have worked on an experimental project aiming to reproduce the phenomena. Good morning sirs! Could you explain to our viewers few words about your researches? ” NOEL ʻThanks to this extraordinary breakthrough, the view of the world about universe and cosmos will never be the same ʼ DOMINIQUE ʻWe have carried out experiments for six years on postulates and equations. We wrote an amazing amount of theorems. Part of the calculating job was accomplished by informationʼs form the computer department, but today, we can assert to the world that black holes are not a mystery anymoreʼ Our work was principally based on Hawking radiance. Before explaining our amazing experiments, we have to understand what a black hole is. (Jacob is in another place with the blackboard, to explain what a black hole is.) JACOB “What is commonly called black hole is a body with such an intense gravity that nothing can escape from its immediate vicinity, even light! It is made of two parts. The first is called singularity. Surrounding that singularity is a region of place from which escape is impossible. That perimeter is called event horizon. Anything can exit a black hole and whatever light the falling body gives off is trapped. The wall finally crashes into the singularity. Here it explains why we cannot see a black hole. The birth of a black hole happens while a super massive star collapse. When collapsing, it first
