Physicists Propose GW190521 as a Wormhole Echo from Another Universe
In May 2019, the LIGO and Virgo observatories detected a gravitational wave event, GW190521, which has sparked significant scientific debate. Unlike typical gravitational wave signals, which follow a predictable pattern of inspiral, merger, and ringdown, GW190521 presented as a brief, blunt signal without a clear inspiral phase. Initially interpreted as the merger of two black holes, forming an intermediate-mass black hole, the event's characteristics have led to alternative theories. A recent paper by physicist Qi Lai and his team from the University of Chinese Academy of Sciences suggests that GW190521 might be a gravitational wave echo from a wormhole, potentially linking our universe to another. This hypothesis posits that the signal could have traveled through a wormhole, emerging as a short burst without the typical pre-merger buildup.
