Scientists believe the two supermassive black holes are located at the center of galaxy SDSS J1430+2303. They pointed out that the fluctuations of light from the galaxy’s center looked very similar to what they expected two black holes to look like during a collision. In addition, they also believe that the combined mass of the two black holes may reach about 200 million suns.
But the collision or even the existence of these two supermassive black holes is not guaranteed. More than a billion light-years away, it’s hard to say what really happened at the center of SDSS J1430+2303. But scientists believe it could be two colliding black holes. And if it can be observed to happen, it has a lot to offer.
But first, look at the evidence. After all, this galaxy is a billion light-years away, so getting information isn’t as easy as walking next door. First, we know that galaxies are home to supermassive black holes. Our own galaxy also has a supermassive black hole. We also know that galaxies sometimes collide — quite frequently — and when they do, new galaxies are created.
By this logic, the idea that black holes could also collide is plausible. And it’s this possibility — and the idea that mergers could give rise to the giant black holes we know — that drives research into this hypothesis. Therefore, scientists want to study it more deeply.
The study, which has been accepted for publication in Astronomy and Astrophysics, also details their findings so far at SDSS J1430+2303. For now, light fluctuations in the galaxy may appear to be two colliding black holes getting closer. But they could also be completely different things. It’s just the nature of space and the many mysteries surrounding it.
