Un agujero negro es una region en el espacio con extrema gravitywhere even light, the fastest thing in the universe, can’t escape.

Según una investigation publicada en The Astrophysical Journal, se estima que The black hole closest to our solar system is about 1,550 light years away and has 12 times the mass of the Sun..

Agujeros negros primordiales nacidos en el Big Bang

Compared to the modern universe, el cosmos primitivo era salvaje y complejo. But the Big Bang marked the transition of the radical phase, the division of fundamental elements and other events that came as a result el cosmos más afable de hoy.

The scientists searched for the physics of the first minutes before the event and came to observe the extreme conditions that form the black holes, like a star collapsing on itself during the last moments of its life. Las estrellas aún were not present in the first seconds of the existence of the universe, but las condiciones adequadas deben haber estado presentes para formar agujeros negros.

Las conditions deben haber sido las adequadas para permitir que los agujeros negros primordiales (those that did not form due to the gravitational collapse of a star but to the extreme density of the universe at the beginning of its expansion) inunden el universo. Fortunately, los agujeros negros no son 100% negros y pierden masa due to the radiation of Hawking. It is the complex process of quantum mechanics that allows some particles and radiation to escape. Cuanto más pequeño son los agujeros negros, más rápido pierden masa.

The total number of small black holes in a galaxy depends on the amount of dark matter present and the size of each one. Pero hay demásios de ellos y cada uno es muy rápido. Computer simulations show that dark matter gas has a velocity of more than 160 miles per second, and A black hole in the mass of an asteroid with that speed could cover the distance between Jupiter and Earth in a couple of weeks.

¿Podría un aguero negro devorarse a la Tierra?

Un article en Big Think details the probabilities of que un aguero negro golpee la Tierra. There it is indicated that, although there are many black holes in the universe, and even in the Milky Way galaxy, las probabilitas de que golpeen la Tierra son incredibilemente pequeñas.

Se estima que hay 1 chance de impacto en 40 mil miliones a lo largo de la historia de la Tierray alrededor de 1 en 1020 (1 en 100,000,000,000,000,000,000) con cada año que pasa.

It is believed that there are 400 billion stars in the galaxy of the Milky Way, and although the individual stars are not the same, The distances between the stars are enormous compared not only to their sizes, but also to the sizes of the star systems that anchor them..

Los agujeros negros son más o menos invisible y difículos de detecter. El professor Roger Romani de la Universidad de Stanford dijo a Newsweek que At 1,500 light years away, the closest black hole to the Solar System is not as close as statistics suggest.

Moreover, the black holes can move around the galaxy instead of orbiting the galactic center. Se llama agujeros negros “rebeldes” que, según la teoría, acechan en el borde del sistema solar, influyendo silenciosamente en las orbits de los planetes exteriores con su gravidad extrema.

El astrofísico Steven Tingay explained a Newsweek que tendía que haber un encuentro muy cercano para que la Tierra fuera destruida por un gran agujero negro. The results of such interaction would be catastrophic even before the planet is destroyed.
