Published in the Monthly Notices of the Royal Astronomical Society of the UK, researchers have found a small galaxy some 90 million light years from Earth in the constellation Big Dipper. It has been called the Markarian 177 – an object that Albert Einstein must have propounded to be the elusive black hole.
Einstein’s black hole proposition in his general theory of relativity posits that when two galaxies collide, they may merge and become one; making the two big black holes in the centers of the two galaxies to merge or fuse together, with the result that gravitational waves formed move out into space to create other effects.
However, if it happens that the two fused black holes have different masses or rotate at differing speeds, the resultant gravitational waves will emanate in an asymmetrical fashion, making the two black holes to move out in two opposite directions. If the jolting force separating the black holes is weak, the fused black holes drift together back again. But where powerful enough, the separated black holes will drift out entirely into the space from the galaxy, causing them to wander eternally in space.
Having been looking for any such wandering black hole in space for decades, astronomers are now wondering whether the newly discovered Markarian 177 object in the constellation Big Dipper might be Einstein’s black hole.
Located about 2,600 miles from the center of the galaxy, is an extraordinary bright object believed to be the black hole. And according to Laura Blecha, a researcher from the University of Maryland, this supposed object is “the most promising candidate we’ve found” for an ejected black hole. However, she states that “It’s either the first example we’ve confirmed in this very exotic class of objects, or it’s the most exotic, extreme example of a very common class of objects,” referring to exploding stars called supernovae – meaning that the object found might be the elusive black hole and it might not be it.
If this happens to be the black hole, then Albert Eistein will have been vindicated in his general theory of relativity, and this would be a great leap in astronomical physics and space science.
Nothing can escape a black hole. The problem is the escape velocity for all black holes is the speed of light or greater. So if two black holes merge unless one of both is going faster then the speed of light once they join together they cannot separate.
