Two black holes are on their way to colliding each other: All you need to know

National Aeronautics and Space Administration (NASA) discovered that two black holes are on their way to colliding each other. The two black holes will collide sooner than expected and the collision will create a titanic blast which has a capability of destroying an entire galaxy.
The researchers said these black holes are about one million light years away which is almost equal to our solar system's diameter. According to the predictions, the collision will have the power of 100 million supernovae which create a death spiral. These spirals will further project ripple like gravitational waves.

Some interesting facts about Black Holes that you must know:

Black holes are the most violent events in the Universe. They are the region of spacetime with strong gravitational effects that not even light can escape them
Our galaxy, the Milky Way galaxy, has a black hole which weighs about 4.3 million solar masses, i.e. 4.3 million times the mass of Sun
When a star dies, it creates a black hole. The black hole that dying stars create is called stellar black holes
Black hole affects time. As per Einstein's theory of relativity time and space are affected by the black hole. The time runs slower due to the gravity
One black hole has a disastrous effect on the planets, galaxies and the Universe. The collision of two black holes will lead to an unimaginable event.
