Can we live in a baby universe formed by a delayed first-order phase transition?

Published 29 May 2025 in hep-ph and gr-qc | (2505.23007v1)

Abstract: We examine the idea that our universe began as a baby universe and show that this is feasible in a $U(1)_{B-L}$ extension of the Standard Model with the classically conformal principle. The framework is consistent with current cosmological data and predicts a heavy neutral gauge boson, which could be detected at colliders.
