A singularity-free WEC-respecting time machine
S. V. Krasnikov
TL;DR
This paper presents a novel time machine model that avoids singularities and WEC violations, with an exterior spacetime similar to the Friedmann universe, challenging previous assumptions about time machine construction.
Contribution
The paper introduces a time machine model that is free of singularities and WEC violations, unlike prior models.
Findings
Constructed a singularity-free time machine respecting WEC
Exterior spacetime resembles Friedmann universe
Challenges previous assumptions about time machine limitations
Abstract
A time machine (TM) is constructed whose creating in contrast to all TMs known so far requires neither singularities, nor violation of the weak energy condition (WEC). The spacetime exterior to the TM closely resembles the Friedmann universe.
