Scientists: A rare gravitational wave may be a signal from another universe
Unlike typical gravitational waves, which are recorded as a prolonged "chirp" when black holes merge in orbit, GW190521 lasted less than one-tenth of a second and was a sharp burst. It had previously been explained as the accidental gravitational capture of two black holes without prolonged orbital interaction.
This was reported by the New-Science portal, citing a new study by a group of physicists led by Qi Lai of the University of the Chinese Academy of Sciences, published in September 2025.
However, the new paper suggests that the signal could be an echo of a black hole merger in another universe. According to the hypothesis, the result of such a process was a wormhole that then collapsed, producing a short gravitational wave.
The authors note that the standard black hole merger model remains the primary explanation for the event, but their calculations show that the LIGO and Virgo data do not rule out the wormhole scenario.
Scientists believe that further observations, including an analysis of the recently recorded event GW231123, could help clarify the nature of such signals. If the wormhole hypothesis is confirmed, it would be the first potential evidence for the existence of such objects and would give physicists a new tool for studying the structure of the Universe.
