Está la materia oscura hecha de agujeros negros?

Buenas,

Me pareció interesante esta nota, donde se habla de un estudio reciente anunciado por la NASA, donde se refuerza la idea de que la materia oscura podría estar compuesta de agujeros negros. Les paso el enlace: http://earthsky.org/space/is-dark-matte ... lack-holes

What if if dark matter consisted of a population of black holes similar to those detected by LIGO last year? A new study analyzes this possibility.

Modern astronomers believe a substantial portion of our universe exists in the form of dark matter. Like all matter, dark matter appears to exert a gravitational pull, but it can’t be seen. If it exists, it emits neither light nor any other form of radiation that scientists have detected. Scientists have favored theoretical models using exotic massive particles to explain dark matter, but so far there’s no observational evidence that this is the case. On May 24, 2016, NASA announced a new study bolstering the idea of an alternative hypothesis: dark matter might be made of black holes.

Alexander Kashlinsky, an astrophysicist at NASA Goddard, led the new study, which he said is:

… an effort to bring together a broad set of ideas and observations to test how well they fit, and the fit is surprisingly good. If this is correct, then all galaxies, including our own, are embedded within a vast sphere of black holes each about 30 times the sun’s mass.

There are several ways to form black holes, but they all involve high densities of matter. The black holes of Kashlinsky’s study are what are called primordial back holes, thought to have formed in the first fraction of a second after the Big Bang, when pressures and temperatures were extremely high. During this time, tiny fluctuations in the density of matter might have pocked the early universe with black holes, and, if so, as the universe expanded, those primordial black holes would have remained stable, existing until our time.

In his new paper, Kashlinsky points to two primary lines of evidence that these black holes can account for the missing dark matter thought to pervade our universe.

Interesante, sería una respuesta dentro del paradigma actual, sin embargo, y uno espera/desea que ya caiga esta física. Pero los deseos no siempre son realidad...

Bueno, parece que hay progresos en el tema, al menos se dicuten limites.
