The coming galactic collision may tear apart the black hole in the center of the Milky Way.

In this Hubble image, the spiral galaxy (M5 1a) and its companion star (M5 1b) are merging. The masses of these two galaxies are similar to those of the Milky Way and large magellanic cloud.

According to a new paper published in the Monthly Journal of the Royal Astronomical Society on June 4th, 65438/KLOC-0, our Milky Way seems to be called the stellar spiral of the Large Magellanic Cloud (LMC) during its collision with its nearest satellite. A team of astrophysicists at Durham University in England simulated the collapse of the universe "KDSP" and "KDSP" in lovely and terrible details, which may start as early as 2 billion years later-2 billion to 3 billion years faster than the long-term expected collision between the Milky Way and its nearest neighbor Andromeda galaxy. (Adjust your doomsday clock accordingly) "KDSP" and "KDSP", although the mass of LMC is only one twentieth of that of the Milky Way Sun, the collision will leave permanent scars on the two galaxies, ignite a dormant black hole, throw the stars out of orbit for trillions of miles, and pollute the sky with explosive cosmic radiation.

"The destruction of the Large Magellanic Cloud when swallowed by the Milky Way will cause serious damage to our Milky Way," Marius Coton, director of the Institute of Computational Cosmology of Durham University and a postdoctoral researcher, said in a statement: "KDSP" KDSP "KDSP" KDSP "KDSP" is a common phenomenon in the surprisingly crowded infinite space when galaxies collide, and scientists are getting better and better at simulating new phenomena. Durham's research team used a supercomputer collision simulator called EAGLE to simulate several possible scenarios of the upcoming Galaxy /LMC merger.

What will happen to our galaxy? First of all, the colliding LMC may inject a lot of fresh gas and stars into the black hole at the center of the galaxy, injecting fresh life into this once-sleeping giant. According to Coton and his colleagues, such a collision may increase the size of a black hole by eight times, and even turn it into a quasar, one of the brightest objects in the universe. This happens when a supermassive black hole sucks in and ejects a hot object at a speed close to the speed of light.

If this happens, the stars now known as the central home of the Milky Way will unfortunately have to give up their familiar and beloved neighbors to welcome a group of new cosmic immigrants from LCM. According to the researchers, many stars will be sucked into the growing black hole in the center of the Milky Way; Other stars react to all the extra mass injected around them and may be thrown into interstellar space 4 trillion miles away from them.

Fortunately, for any offspring who may leave after 2 billion years, the author writes that only a few stars living in the approximate area of the earth's sun will be affected by the merger. Researchers predict that any threat to life on Earth is "impossible". On the brighter side, the new quasars in the Milky Way can actually regard the future earthlings as "a spectacular cosmic fireworks show", said Carlos Frenk, co-author of the study and director of the Durham Institute of Computational Cosmology.
