Story summary

In 2019, researchers from the Chinese Academy of Sciences propose that GW190521 signal arose from a black hole collision in another universe, a theory that could briefly connect to our universe via a temporary wormhole.
They note the signal's short duration lacks the inspiral phase.
A 2023 detection by the Laser Interferometer Gravitational-Wave Observatory (LIGO) and Virgo shows similar characteristics.
