A black hole is a region of spacetime where gravity is so strong that nothing no particles or even electromagnetic radiation such as light can escape from it.

Black Hole

One black hole is bad enough but if you took two black holes and smashed them into each other they'd be capable of changing the shape of space itself, how large would that explosion be and could it somehow reach earth?

What If Two Black Holes Collided?

You see the two black holes getting a little closer until they starte to orbit each other they would beging pulling matter and gas into a vortex between them "get comfortable because it could take billions of years for their centers to merge" but as the two black holes merged into one they wobble a little and then settle down into a new bigger black hole.

At First 

the excess energy from the collision would be expelled back into the universe as gravitational waves.

Then

colliding black holes can change the shape of the space around them. they do it by rippling this space with gravitational waves.

They Can Change Shape Of The Space Around Them. 

Albert Einstein predicted gravitational waves over a hundred years ago but scientists didn't observe them until 2015 when the advanced LIGO gravitational wave Observatory finally detected gravitational waves after eight years of operation.

The Grativational Wavies

These waves affect the distance between the Sun and the earth they only change it by the diameter of a hydrogen atom you'd need a whole lot of colliding black holes to really see a difference.

The Effect Of It On Earth

Would their collision be more explosive? these black holes have a mass of at least hundreds of thousands of times the mass of our Sun but the thing is they might never even collide at all two supermassive giants would get close to each other until they reached a gravitational balance and froze in their respective orbits.

What About Supermassive Black Holes

The three of them could tip over the gravitational scale and finally collide not in a massive cosmic explosion but a silent merger sending powerful gravitational waves throughout the universe.

But Add Another Supermassive Black Hole To The Equation

Although black holes are unstoppable & insatiable force from which nothing can escape we have nothing to fear from their collision. Unless maybe if that collision happened somewhere near our solar system then the merging black holes would rip all the planets.

Conclusion

And please check out the video for more details.

Black holes are the gravitational monsters of the Universe. They are so powerful that nothing, even light, can escape their grasp. One black hole is bad enough. But if you took two black holes and smashed them into each other, they'd be capable of changing the shape of space itself. How epic would that explosion be? And could it somehow reach the Earth?

An epic exploration of possibilities. What If is a Webby Award-winning science web series that takes you on a journey through hypothetical worlds and possibilities, some in distant corners of the universe, others right here on Earth. Each scenario examines a scientific theory, research or fact through a hypothetical question.
