Physicists believe that they found traces of wormhole in space in another universe

In 2019, LIGO and Virgo detectors recorded an unusual signal of gravitational waves – a flash of less than a tenth of a second of a second. Unlike the usual lingering signals with an increasing frequency, which give double black holes with a spiral rapprochement, this one was short and sharp. It was designated as GW190521. The initial, most plausible interpretation explained the event with an accidental clash of two black holes that did not rotate in a close orbit.

However, a new work is a much more exotic explanation, writes Scienceealert. A short surge could be an echo of clash of black holes in another universe, which passed through the collapsing “mole” (Wormhole), formed as a result of a merger. Authors – scientists from the University of the Chinese Academy of Sciences under the leadership of Chi Lai Physicist – published a preprint on arXiv.

Mole-nora, or wormhole, is a hypothetical tunnel in the space-time space, connecting two points, allowing you to overcome a huge distance or time faster than along the usual path. This is a consequence of the equations of the general theory of Einstein’s relativity, and exotic matter with a negative energy density is required to stabilize such a pass.

It is important to emphasize: the classical explanation – the accidental fusion of black holes in our universe – remains preferable. Nevertheless, as the authors write, the difference in accordance with the data of observations with two models was extremely small, and therefore the option with a wormhole cannot be completely excluded.

The gravitational waves that we register are fluctuations in space-time that arise during the accelerated movement of massive compact objects, such as black holes and neutron stars. During a classic merger, two black holes revolve for a long time around the common center of mass, radiating waves with increasing amplitude and frequency-the so-called “chirus” (chirp-signal). In the case of the GW190521, the signal part corresponding to a prolonged rapprochement was absent, although with the bred mass of the resulting object (~ 142 sunny), such an inspiral should have been. Hence the conclusion that the bodies simply flew nearby and collided.

Lai and co -authors offer a different path: to assume that as a result of binary merging, not immediately a stable black hole was formed, but a short -term wormhole, which then collapsed, forming an ordinary black hole. With this development of events, observers in our Universe could only reach a short impulse of gravitational waves – just the same sharp surge.

Researchers simulated the shape of a wave signal for a script with a collapsing mole tunnel and compared it with real data detectors. For comparison, they also calculated a wave corresponding to the standard merger. It turned out that the second gives a slightly better correspondence to the observed signal, but the difference is small – enough to allow an alternative interpretation.

If the GW190521 was indeed an echo in a kind of hole, this would not only confirm the existence of such hypothetical objects, but also a way to study their properties through gravitational wave astronomy. But such a hypothesis requires an “exotic” physics, although it does not contradict careful skepticism: it intrigues, but does not prove the existence of mole Nice.

A comparison of such signals in the future will check how viable the idea of ​​passing the waves through collapsing mole tunnels.
