Publicity

What if we questioned the vacuum today? Yes, the vacuum: what remains when we have removed everything ... But the problem, if we remove everything, is that there is nothing left, not even the vacuum. So can we really make a vacuum?

With the physicist and philosopher Étienne Klein for his new work What is without being entirely. Essay on the vacuum , published by Actes Sud.
