The laser intensity will gush matter vacuum

The biography of the equation E = mc 2 is far from complete. The remarkable illustration given in the documentary drama broadcast by Arte on Sunday 16 October (A biography of the equation E = mc2, Gary Johnstone) could soon know a new chapter exciting.

At the Applied Optics Laboratory (LOA), at the Ecole Nationale Supérieure de Techniques Techniques (Ensta), the Ecole Polytechnique and the CNRS, Palaiseau (Essonne), Gérard Mourou is getting closer to the moment when he can bring matter from emptiness ...

"Void is the mother of all matter," he says with a certain jubilation. In the perfect state, "it contains a gigantic quantity of particles per cm3 ... and just as many antiparticles". Hence a zero sum that leads to this apparent absence of matter that we name ... emptiness. What challenge the dictionary definition for which, since the fourteenth century, the latter is a "space that is not occupied by matter". It was counting without the antimatter and without the famous formula E = mc 2, which Albert Einstein deduced from the special relativity a hundred years ago, in 1905.
