>>10825302if you want a better physical example of this, then look up Polchinski's Paradox. it's better because it is based on actual general relativity, in particular studying spacetimes (allowed solutions of the einstein field equations) that have a traversable wormhole where you might get this sort of paradox in a simple way that you can analyze, pic related.
my opinion on this is that GR may allow paradoxical solutions, but that these solutions must be ruled out since they violate causality, so basically no, the answer is that it's not allowed in real life
