A team of researchers has found signs of stray black hole hiding in the Milky Way.
It is difficult to find black holes, because they are completely black. Often, it is the effect which they cause that they can be seen. Like, a molecular cloud with enigmatic motion. Studies predict around 100 million to one billion black holes exist in the Milky Way.
The data indicated that the Bullet seems to jump out from the edge of the supernova remnant with immense kinetic energy. “Its kinetic energy is a few tens of times larger than that injected by the W44 supernova. It seems impossible to generate such an energetic cloud under ordinary environments,” Masaya Yamada, a graduate student at Keio University, said.
