Much Ado around Nothing: The Cosmological non-Constant Problem

Tl;dr: Researchers put forward a theoretical argument that new physics must appear at energies much lower than commonly thought, barely beyond the reach of the LHC.
The cosmological constant is the worst-ever prediction of quantum field theory, infamously off by 120 orders of magnitude. And as if that wasn�t embarrassing enough, this gives rise to, not one, but three problems: Why is the
