Elementary Constituents Conjecture

Abstract

In this note, we conjecture and provide evidence that quantum gravity cobordism classes are trivialized by elementary generators with tension at most order 1 in Planck units. Motivated by the attractor mechanism and a number of key examples, we propose that there is always a regime in the field space of the EFT in which the intrinsic tension of such an object is at most Planckian. This work brings together kinematic and dynamical aspects of cobordism defects in the context of the Swampland program.
