Is this gravity wave signal coming from the black hole, or is there a stranger?

Foreign sticky stars can reflect the waves of space -time, and imitate the gestures that we observe with black holes.
Since 2015, researchers have been learning that the contents of the universe have to be seen not only light waves but also the waves of gravity: waves in the fabric of the universe. Gravity waves, like the waves of light, can also be reflected – but just a extraordinary sticky structure, like the waves of light, at the Niles Bohr Institute in Denmark – like light waves.
Researchers started raising the question whether the mirror of gravity waves could also be present. Although some past studies suggested that this may happen, he struggled to write equality that would explain such a mirror without breaking the laws of physics. Then, they realized that the reflection item should not be flat.
“We can have a spherical mirror, and then we just need a star.” But this star will need a very high vesicanity as equal to the cosmic of the ball. Researchers’ calculations show that such a star will reflect the waves of gravity because it will be very severe when it passes through it.
Daniel Kennifk at the University of Arkansas says the behavior will be very unusual because most of the matter is transparent with the waves of gravity, such as transparent in glass light. “Even if we were very close to a very powerful source of gravity waves, it would not harm us at all, because energy would pass through us.”
Increasing its strangeness, enough star adhesive to relieve the waves of gravity will also have to be very compact and very close to falling into the black hole. In fact, Redondo – JUST says that the Black Hole itself is incredibly sticky – so much so that when the signature of their gravity wave is recorded on the ground, other sticky items can look like them. At the same time, these signatures may make a small difference. For example, a collision between adhesive stars and collision between black holes will provide a slightly different gravity wave indicators, as the stars have a more maritime effect on each other.
Researchers have previously observed the cosmic things that are thought to be high and poor, such as very hot neutrons stars that form other neutrons through the integration of stars. Paulo water at the University of Rome in Rome in Italy says or can it be quite sticky to meet the team’s mathematical model.
He says that in the future, gravity can provide more detailed information about the viscosity of items that detect the wave that we already know – and can help us find new. “This is an example of a premature attempt to determine the time we should look for,” says Kenfik.
So far, no observance data has given researchers a strong reason to think about what they identified as a black hole is actually a foreign star. And the three researchers say that the chances of sticky stars are not high.
Redondo – JUST says, “But I think we have a duty to continue these tests. This is the only way to make a complete inventory of our universe filling items.
