The Takeaway
In 'bouncing universe' models where the cosmos collapses and expands again, most structures are destroyed. This study proves that specific dynamical wormholes could act as stable bridges that survive this transition, potentially carrying information from a previous universe into ours.
From the abstract
We investigate whether a dynamical wormhole could survive in a universe that undergoes a cosmological bounce. First, the conditions under which a wormhole could persist from a contracting to an expanding phase of the cosmos are presented. Then, the only two known cosmological solutions of Einstein's equations representing wormholes are analyzed, and it is shown that both dynamical wormholes exist for all cosmic times on both sides of a bouncing universe and at the bounce itself. We also provide
