Hey guys here I am Goutam, today I taking "what would happen if two black hole collide". It is possible for two black hole collide. When a black hole comes to close of another black hole then it can't escape from each other.
Then when it is marge to each other it turned into a supermassive black hole. At that time it will so powerful and send a massive ripples through the space-time which is called gravitational waves.
A black hole is a region of spacetime exhibiting such strong gravitational effects that nothing—not even particles and electromagnetic radiation such as light—can escape from inside it.[1] The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole.[2][3] The boundary of the region from which no escape is possible is called the event horizon. Although the event horizon has an enormous effect on the fate and circumstances of an object crossing it, no locally detectable features appear to be observed.[4] In many ways a blasck hole acts like an ideal black body, as it reflects no light.[5][6] Moreover, quantum field theory in curved spacetime predicts that event horizons emit Hawking radiation, with the same spectrum as a black body of a temperature inversely proportional to its mass. This temperature is on the order of billionths of a kelvin for black holes of stellar mass, making it essentially impossible to observe.

As we all know there are more black hole in our universe and the black holes are keep their moving all time. However the supermassive black hole are dangerously moving near each other. It is not irrational to assume that they might collide. According to the theoretical models this black holes are keep their movable moment and eventually the black holes are collide. But till nobody is witness of it.
It is not possible to observe normally the gravitational waves. Here we need some important instruments to detect it. The scientists announced on august that they recorded a gravitational waves from the space-time, from a pair of black hole collision. The collision was recorded from a many billion light years away. It is recorded by the world's largest gravitational waves observatory, LIGO (Laser Interferometer Gravitational Waves Observatory). The scientists working with LIGO to find more some insight. LIGO & VIRGO (3 km long interferometer) work together. A new gravitational waves detector invented in Italy by European gravitational observatory. The astronomers keep continue their work with LIGO to improve the instruments before fall of 2018.
