The theory says that there have been a collision between two galaxies and the black holes of these galaxies began to gravitee around each other. The collision of two galaxies is resulting in the formation of a new one

This phenomenon was observed by NASA’s Hubble Space Telescope, and the mass of the black hole is the equivalent of a Billion Suns (the largest cosmic object which leaves its place, noticed so far).

The cause of this event is the gravitational waves, whose existence was first predicted by Albert Einstein – gravitational waves are waves in space resulting from the proximity of two massive objects.

When two black holes collide, gravitational waves cease to be produced, so the new-formed black hole will ‘fly’ in the opposite direction of the strongest gravitational wave, so it will be threw from the center of its galaxy.

This illustration shows how gravitational waves can propel a black hole from the center of a galaxy. The scenario begins in the first panel with the merger of two galaxies, each with a central black hole. In the second panel, the two black holes in the newly merged galaxy settle into the center and begin whirling around each other. This energetic action produces gravitational waves. As the two hefty objects continue to radiate away gravitational energy, they move closer to each other over time, as seen in the third panel. If the black holes do not have the same mass and rotation rate, they emit gravitational waves more strongly in one direction, as shown by the bright area at upper left. The black holes finally merge in the fourth panel, forming one giant black hole. The energy emitted by the merger propels the black hole away from the center in the opposite direction of the strongest gravitational waves. Credit: NASA, ESA, A. Feild (STScI) and Phys.org

Scientists say that this event produced so much energy that it’s force has the equivalent of the explosion of 100 million supernovas exploding at the same time.
Reasearchers team hopes to continue using the Hubble telescope to measure the speed of the black hole, which is currently estimated at 7.5 million kilometers per hour (it can travel the distance between Earth and moon in just 3 minutes).

If it’s real speed is the actual speed , the black hole will leave its Galaxy in about 20 million years.

  1. I don’t really believe that someone can take a look that far and see two black holes colliding…

  2. I don’t really believe that someone can take a look that far and see two black holes colliding…

  3. This universe is so big… Will our generation ever discover what’s the secret with it?

  4. I have seen this story in more detail in other scientific publications. I might be more impressed with your presentation if you were able to use English correctly.

    • Hello Allen! We are sorry if one of our editors misspelled a phrase.About the story, we are trying to make a short description of the event, the most important details.
