Black holes that eat their nearby stars give information about the formation of those mysterious objects.

Researchers observed 18 black holes that pull material from nearby stars. That research gave information about black hole's nature and their interaction with 3D spacetime. We know that the most powerful object in the universe is not stable. All black holes vaporize, and whenever they send gravitational waves. 

And sooner or later all black holes turn into gravitational waves. The vaporization speed is not stable. When a black hole pulls lots of material in it vaporization is slow. But when there is no material that a black hole can pull in that increases the vaporization speed. Sometimes black holes pull too much material into them. 

That thing forms a short-term cosmic void around the black hole. And in that moment black holes lose extraordinary lots of mass. If a black hole also pulls quantum fields inside it with speed. That creates a quantum vacuum around the black hole. And other fields cannot replace that field immediately. A black hole sends extraordinarily strong gravitational waves. 

A black hole is an extremely heavy object. And even small mass percent that leaves from black holes causes massive effects. The effect where those black hole's mass turns into gravitational waves causes a situation, that black holes are not stable. If we think that 6 sun mass black hole loses Earth mass material that affects the trajectories around the black hole, in that case, lots of photons and electrons will slip out from the black hole's massive gravity. 

When black holes pull material from nearby stars it should expand. When a black hole's mass rises its gravity field should turn stronger. But if material vanishes somewhere. That thing can cause black holes to not expand. In some models, the researchers will get evidence of the wormholes existing by observing black holes that will not expand even if they pull very much material in them. 

But as I wrote many times before black holes are extreme objects. They pull radiation in them. When the event horizon oscillates it sends wave movement also into the black hole. That wave movement reflects from its core. Or from somewhere from inside the event horizon. 

The gravitational waves are an interesting thing. They are wave movements just like all other wave movements. It's possible that most gravitational waves are forming in the standing gravitational waves or gravitational fields should form the event horizon. 

A black hole is an interaction. Upcoming quantum fields press the black hole from outside. And incoming gravitational radiation tries to push that event horizon away. If outcoming quantum fields do not exist the black hole will detonate. 

In some models, the giant Boöetes void and some other cosmic voids are formed when some black holes are vaporized or detonated with extremely fast speed. There is a theoretical situation that a very large and bright star detonates as a supernova. That shockwave can form a cosmic void that surrounds the black hole. Then that cosmic void rips the black hole into pieces. In those models, there is no counterpressure for the radiation that comes out from the black hole.
