ESA's Gaia mission found a new and very interesting type of black hole.

The film is introducing a motion of a new type of black hole, or binary star which another participant is the red giant. And the second one is about ten stellar mass black holes. The red giant star orbits the black hole in three years.  Interesting thing is that the black hole seems to rotate around the invisible mass center. Distance from the Earth to this binary system is 3800 light years. 

There is another black hole 1500 light years away from Earth. The thing is that there is a small possibility that those black holes could interact with each other. If that interaction is real that will be the first real evidence of wormholes. But when we are looking at the film we might ask, is there another black hole near the larger black hole? Or what makes the black hole also wobble? Does the mass of the red giant be enough for that thing? 

The thing is that black holes could be closer than we even think. The virtual redshift around those objects can be very strong because particles fall in them at very high speeds. 

"ESA’s Gaia mission has helped discover a new kind of black hole. The new family already has two members, and both are closer to Earth than any other black hole that we know of. The two black holes were discovered by studying ultra-precise measurements of stellar positions and motions in Gaia’s third data release. A strange ‘wobble’ in the movement of two stars in the sky indicated that they are orbiting a very massive object. In both cases, the objects are approximately ten times more massive than our Sun". So that is a stellar-mass black hole. (ScitechDaily.com/Gaia Discovers a Mysterious New Type of Black Hole – And Two Are Lurking in Earth’s Cosmic Backyard)

"Other explanations for these massive companions, like double-star systems, were ruled out since they do not seem to emit any light. Gaia’s second black hole, BH2, is located 3800 light-years away from Earth. It is a binary system consisting of a red giant star and likely a black hole. In this animation of Gaia BH2, created in Gaia Sky, the orbits are accurately sized, but the back hole diameter is not to scale.

"The location of the first two black holes discovered by ESA’s Gaia mission in the Milky Way. This map of our galaxy was also made by the Gaia mission. Gaia Black Hole 1 is located just 1560 light-years away from us in the direction of the constellation Ophiuchus and Gaia Black Hole 2 is 3800 light-years away in the constellation Centaurus. In galactic terms, these black holes reside in our cosmic backyard.

 But the thing. What makes those black holes interesting is that they are similar. They don't have almost any kind of radiation. Because their companion star is far away from them. Gaia found those black holes by searching the wobbling of the visible participant of the binary system. The remarkable thing is that Gaia found those black holes at the same time. And they seem very special.
