Sagittarius A* could be a huge balloon of dark matter/Sagitario A * podría ser un enorme globo de materia oscura

Cosmologists affirm that in the center of a large percentage of spiral galaxies in the style of the Milky Way have a black hole of several thousand solar masses lurking in their center, specifically in our galaxy we have Sagittarius A * which is calculated to have a size of about 3.7 million times the mass of the Sun.

Los cosmólogos afirman que en el centro de un gran porcentaje de las galaxias espirales del estilo de la Vía Láctea tienen acechando en su centro un agujero negro de varios miles de masas solares, concretamente en la nuestra tenemos a Sagitario A* que se calcula que tiene un tamaño de unos 3,7 millones de veces la masa del Sol.

All this has been deduced by experts from the movement of the stars located in the center of our galaxy and their excessive speed but, with the observations made recently, some doubts about their existence arise and suggest that, instead, there may be a immense globe of dark matter.

Todo esto lo han deducido los expertos del movimiento de las estrellas situadas en en centro de nuestra galaxia y su desmesurada velocidad pero, con las observaciones realizadas últimamente surgen algunas dudas de su existencia y apuntan a que, en su lugar, puede ser que haya un inmenso globo de materia oscura.

The problem was caused by a huge cloud of gas that they observed passing presumably in front of the black hole without being affected by its gravity, that is, without being dramatically absorbed by the powerful force of attraction of the black hole, which, a priori, calls into question the existence of a black hole in the vicinity.

El problema lo suscitó una enorme nube de gas que observaron pasando presuntamente por delante del agujero negro sin verse afectada por su gravedad, es decir, sin verse absorbida dramáticamente por la potente fuerza de atracción del agujero negro lo que, a priori, pone en duda la existencia de un agujero negro en las inmediaciones.

Faced with this enigma, some cosmologists propose that in reality Sagittarius A * is no more, no less, than a huge balloon of dark matter that would also explain the movement of the stars near the center and that, in addition, would also provide an explanation for the behavior of the stars that are not near the center of the galaxy.

Ante este enigma algunos cosmólogos proponen que en realidad Sagitario A* no es mas, ni menos, que un enorme globo de materia oscura que también explicaría el movimiento de las estrellas cercanas al centro y que, además, también aportaría una explicación al comportamiento de las estrellas que no se encuentran cerca del centro de la galaxia.

Unlike black holes, dark matter is distributed throughout the universe, passing through our body and affecting the behavior of all the stars in the galaxy, while black holes only exert their influence in their vicinity and do not affect at all the stars that are far away.

Al contrario que los agujeros negros la materia oscura se reparte por todo el universo, atravesando nuestro cuerpo y afectando al comportamiento de todas las estrellas de la galaxia mientras que los agujeros negros solo ejercen su influencia en sus inmediacione y no afectan para nada a las estrellas más lejanas.

This is not something that directly influences us because, regardless of whether what causes the frantic dance of the stars near the center of the galaxy, is a black hole or a ball of dark matter, tomorrow we will have to go back to work like every Monday , but in the end all the discoveries end up having some application in real life.

Esto no es algo que nos influya directamente pues, independientemente de que lo que provoca el frenético baile de las estrella cercanas al centro de la galaxia, sea un agujero negro o una bola de materia oscura, mañana tendremos que volver a trabajar como todos los lunes pero al final todos los descubrimientos acaban teniendo alguna aplicación en la vida real.

Hola @mauromar, estos científicos me recuerdan a alguien con su vocabulario.

@mauromar friend

Your topics are undoubtedly one of my favorites, if our galaxy is in a great mass of Dark matter, then what makes it spin? well, since we know nothing about Dark matter because it does not interact with Ordinary matter, there are more questions than answers, but that's our universe.

It is too complicated for us, each question we answer we get another ten new questions.
Thanks for comment.
