Black Holes Simulation. 2 merging into 1

Black Holes have raised huge interest last days due to the Science Fiction Movie Interstellar. But even the movie explains nor common people knows exactly what Black Holes really are. At Fair Science we are preparing a special edition on Black Holes for dummies, so stay tuned and give us suggestions on the comments.  Here is a taste:

A black hole is a massive object whose gravitational field is so intense that no light (electromagnetic radiation) can escape it. When two orbiting black holes merge, a massive amount of energy is released in the form of jets. Meanwhile, the movement of these massive bodies disturbs the fabric of space-time around them, sending ripples of gravitational waves radiating outward. These waves are predicted by Einstein's theory of general relativity, but have yet to be directly detected.

In this video, we see a closer look at the center of a spiral galaxy reveals a pair of black holes locked in a death spiral. When they merge, the massive amount of energy is released in the form of jets.

Taday let's have a look to a Video from NASA about Two Black Hole merging into 1. An  interstellar fight between Black holes!
