An unusual gravitational wave, which instead of long “chilreios” has made a “abrupt crack”, may be a sign of the collapse of a Wormhole that connected two universes.
In 2019, the observatories turn on and something unusual: A gravitational wave event with less than a tenth of second duration.
In contrast to Long “Chilreios” of black holes in collapse orbital spiral holes, it was a crash. The best explanation for the phenomenon, named after GW190521It was a fortuitous meeting of two black holes who captured each other as they passed each other.
Now, a new article presents a alternative hypothesis, much more exotic: the echo of the collision of black holes in another universe, resonating through a wormhole in collapse, formed precisely as a result of this fusion.
It should be clarified: the collision of black holes in our own universe remains the most consensual interpretation for this strange sign, notes the.
But this preference It is not solid enough To completely discard the Wormhole model, writes the team led by the physicist Qi Lai, from the Academy of Sciences of China, in a pre-tested arXiv.
If it was indeed a Wormhole, the GW190521 – and other similar signs – not only would confirm the existence of these hypothetical structures and extraordinary, as well as give us a new tool to explore their physical properties. But it is a huge “if”.
The ones we are currently being able to detect are ripples in the tissue tissue, generated by and dense, such as black holes and neutral stars.
However, It is not just the collision itself that creates these ripples. When a pair of black holes in binary orbit approaches spiral, their gravitational fields in interaction also produce undulatings: first weaker, then increasingly intense as the bodies approach.
The resulting “chilreio” has thus A form of ascending wave – As can be seen in several simulations.
The GW190521 did not present this initial part of the sinal. And taking into account the mass calculated (142 times the mass of the sun), this sign should have been detectable.
This led to the conclusion that Black holes were not stuck in a binary orbit, but simply crossed, ends up sucked to the same gravitational well and merging.
Lai and his team considered, however, another possibility: And if the object formed in the binary fusion of black holes It was, after all, a Wormhole that collapsed To give rise to the final black hole? In this case, we could have received only a brief pulse of gravitational waves corresponding to the collapse of Wormhole.
The researchers then developed a wave For this scenario and compared it with the Ligo and Virgo data. Also built a wave form for a conventional binary fusion of black holesfor direct confrontation with the observations.
The waveform of binary fusion adjusted slightly better to the observed signal than that of Wormhole – but only slightly.
There is enough margin for doubtthe authors argue, so that the Wormhole scenario cannot be discarded. Which means that the GW190521 may have been the first time humanity will have glimpsed another universebeyond the borders of ours.
It does not mean that we should hurry to proclaim the existence of Wormholes, especially because this explanation requires a highly exotic physics. But it means that it is worth continuing the investigation by this path.
A fusion of more massive black holes detected to this day, the GW231123, originated an object with 225 times the mass of the sun. It was also relatively brief, similar to the GW190521.
Comparisons between these events and others that are still being registered, the researchers say, can offer a method to test their conclusions and find out which of the scenarios is more plausible.
