What happens if black holes meet each other?

😐 Something like the battle of the boiler and the refrigerator is subconsciously expected here. It implies some kind of spectacular interaction. After all, the huge values of gravity and incredible attraction should not remain unnoticed when meeting. And here's the next question...One hole absorbs everything in its path, the second one does the same. Will they devour each other?

Black holes will really just swallow each other up. There is even such a term "merging of black holes". When black holes merge, there is no grand explosion or anything like that.

Imagine two soap bubbles connected to each other and floating on the surface of the water. In the end, they suddenly merge into one big soap bubble. Black holes also "touch" and immediately form one larger object. They will fluctuate from merging until eventually they find equilibrium again in an almost perfect sphere.

But the gravitational waves they emit will be simply amazing. They will be simply gigantic and will radiate with such force that they will literally stretch and compress the fabric of space.
