Mysterious events have been discovered by researchers from several universities in North America. The galaxy A2261-BCG appears to have lost its black hole, some scientists think it may be floating in space.

This means that the existence of an extremely strong force in the galaxy could have pushed the supermassive black hole out and sent it far away.

In fact, almost every galaxy in the universe is thought to have a giant black hole at its center, including our own, the Milky Way.

Dr. Kayhan Gultekin from the University of Michigan was the one who studied the A2261-BCG galaxy when he noticed signs that the black hole was missing.

"I was very skeptical and thought we would see something in the middle. But it turned out not to be," said Dr. Kayhan Gultekin.

The team also found that the black hole may still be lurking somewhere in the galaxy but is difficult to detect.

Meanwhile, the force strong enough to push a black hole out could be two supermassive black holes colliding. Supermassive black holes have never been observed fusion so finding evidence of this would be a breakthrough.

Scientists from NASA and the European Space Agency say they will focus more on this galaxy mystery.
