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.

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

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

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.

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.

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.

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.

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.
