Double trouble this #BlackHoleFriday :

⁣What would it look like if we could sit and watch two supermassive black holes colliding? This simulation using advanced computer modeling shows what might happen.⁣

⁣

Here we see two supermassive black holes, which are millions to billions of times the mass of the Sun, heading for a collision.⁣

Video description: At the beginning of this animated GIF, we see the glowing gas surrounding two black holes. The gas is shaded orange and purple, and it is tightly wound around each individual black hole. They each have a tail of gas, looking like a comma. As the animation proceeds, the camera moves to see the two black holes nearly in line with each other and then back to see the bottom of the system. As the view tilts, the gravitational effects of the black holes at the center cause the light to bend like a funhouse mirror.⁣
