This Supermassive Hole in the center of our Galaxy was called Sagittarius A*. Recently was presented a study with evidences of small holes, around our giant of the Galaxy.
As we delve into the subject it is important to know how the black holes were discovered. Astronomers Bruce Balick and Robert Brown observed in 1970, an intense radio emission coming from the center of our galaxy.
Over the years they noticed that some stars were being compressed in the same area of these emissions. And it is the black holes that have this capacity.
We cannot see these holes as one big vacuum cleaner that can destroy the entire galaxy. They are mainly gravitational anchors for the group of stars that orbit it, even the furthest away. For a black hole to be able to absorb a star it would need a direct impact and this does not happen very often.
Black holes can also create.
Nasa Chandra’s special telescope, records important data from black holes. Where one observes the emission of a large cloud of gas that appears to be cold hydrogen. At the same time it is expanded in an undulatory way and even in the direction of the Earth.
This important finding manifests the feedback of the whole galaxy. It could be observed by the cold gas propulsion of hydrogen in front of the hot gas and originated the X-ray waves.
These undulating arcs could represent giant explosions, when the hole expelled matter into the galaxy. This could have generated a great landscape in the galaxy.
For now it has not been determined that the Black Holes represent an imminent danger to the galaxy, as the distance is millions of light years.
With these latest advances not everything is destruction, but they can create or emanate certain gases that could not be harmful to the Universe. It could be worrying for humans in just a few trillion years.
