SPECIAL ISSUE — Selected Essays from the Annual Essay Competition of the Gravity Research Foundation 2018 and Invited Papers; Editor: D. V. Ahluwalia

Abstract

We argue that when a theory of gravity and matter is endowed with (classical) conformal symmetry, the fine tuning required to obtain the cosmological constant at its observed value can be significantly reduced. Once tuned, the cosmological constant is stable under a change of the scale at which it is measured.

This essay received an Honorable Mention in the 2018 Essay Competition of the Gravity Research Foundation.
