By presenting 13 correlations involving Avogadro's number, Jean Perrin definitively imposed the idea of the atom, i.e. the negation of the infinitely small. Here, we're talking about both the negation of the infinitely large and the "infinitely insignificant" advocated by officials. textit{We are therefore alone in the Universe}, which the James Webb telescope should confirm. Already, the observation of old galaxies instead of the baby galaxies predicted by standard cosmology destryesz the latter. This failure of cosmology has brought science to a standstill. In particular, CERN failed to detect the expected super-symmetric particles, forgetting Eddington's prophecy of Proton-Tau hyper-symmetry, here linked to cosmology. What we haven't realized is that understanding the quantum world requires cosmology, which therefore appears to be the essential discipline. In fact, it even provides a limit to science, since there is a PERMANENT CREATION of neutrons. Although too weak to be measured directly, this is manifest in the baby galaxies revealed by Halton Arp. The lack of mastery of quantum phenomena is evident in the turbulent history of the laser, still misunderstood, in the quantum Hall and Josephson effects, and in the lack of understanding of climato-cosmic effects. Unlike Perrin's relations, ours are directly verifiable by everyone, which finally rehumanizes Science
