A significant blow came with the paper known as ESSW, an acronym built from the names of its four authors.
According to Englert, now at the National University of Singapore, the Bohm trajectories exist as mathematical objects but lack physical meaning.
I could understand a universe where nothing can go faster than light, but a universe where the internal workings operate faster than light, and yet we re forbidden from ever making use of that at the macroscopic level—it s very hard to understand.
