TL;DR
This paper suggests that certain cosmological singularities in tensionless string theory may be mere gauge artifacts, supported by evidence from both spacetime and worldsheet perspectives.
Contribution
It introduces the idea that unbroken stringy gauge symmetries in tensionless string theory can render some cosmological singularities as gauge artifacts, providing new insights into singularity resolution.
Findings
Cosmological singularities can be gauge artifacts in tensionless string theory.
Evidence from spacetime and worldsheet perspectives supports this view.
Abstract
We argue that in the tensionless phase of string theory where the stringy gauge symmetries are unbroken, (at least some) cosmological singularities can be understood as gauge artefacts. We present two conceptually related, but distinct, pieces of evidence: one relying on spacetime and the other on worldsheet.
