The smallness of the measured Cosmological Constant (CC) is considered to pose one of the deepest conundrums in physics. In this talk I will present a new approach to resolve the problem, ensuring that regions of space with a large CC are short lived and are dynamically driven to crunch soon after the end of inflation. Conversely, regions with a small CC are metastable and long lived and are the only ones to survive until late times. I will discuss a realization of this scenario and its observational implications. In particular, I will argue that new physics at the weak scale, such as supersymmetry, is needed in order to solve the CC problem all the way to the UV cutoff scale. Curiously, in this approach the weak scale arises as the geometric mean of the temperature in our universe today and the Planck scale, hinting on a new “CC miracle” which singles out the weak scale independently of electroweak physics.
