It’s a good time for black hole mergers: the Universe is rapidly expanding and mergers are needed to keep it from shrinking. Black holes are expected to be around for as long as the Universe, so they can’t be expected to collapse in on themselves. The current Universe is probably a product of a singularity, so if singularities are the reason for the Universe’s current expansion, then merging black holes should be the result of a singularity.
These simulations have shown that black holes form when matter and antimatter are “collided.” When the universe started in the Big Bang, matter and antimatter were in equilibrium. After about 13 billion years, however, matter made two quantum leaps and became the antiparticle of matter. Antiparticles have a negative charge. They exist as a sort of tiny electron, with zero electric charge.
This strange quantum state, known as a quantum “hole,” is something that could not exist in our Universe. There are lots of ways to explain what happens next. One way is that matter and antimatter are annihilated and combined, leading to the formation of a single massive object called a “spark.”
The universe “fused” that antimatter into matter, then the “fused” matter into a supermassive black hole. Scientists have speculated that at that moment, everything was just dark matter (which is non-physical) and antimatter (which is physical).
Black holes get their name because they emit a strong gravitational field, called a black hole radiation, and they emit that radiation like a sun in a ring. When you look through a telescope (at a particular spot in the sky) you can see the black hole radiation as it gets pulled in towards the center of the black hole. The farther out it gets, but on each orbit it travels faster, and the energy of this pull increases. Eventually, when the black hole reaches its centre, a gravitational wave will be produced. In order to explain black hole mergers, I think, the Universe must be flat. In the past, the idea of black holes was much more difficult than what we know now. Einstein was the first to argue that there must be a special relationship, which he called a “special curvature.” It must be that black holes exist within our Universe, but we think otherwise. When a black hole emits gravitational waves, it can be predicted that those gravitational waves will travel in almost straight lines. The path of that gravitational wave has to follow the laws of physics. The black hole has to be spinning at about the same rate that light travels through the sky, which is pretty slow unless you’re the largest object in the Universe. The idea that black holes are the result of singularities (the idea that all the matter in the Universe has suddenly exploded, followed by a singularity of some sort) has also never been seen. The only way to think we might find another version of this is if something really, really big goes supernova in our Universe while we’re still around and, due to gravity, stops falling essentially, the black hole should be the object that’s going to explode, that’s going from side to side (in a straight line). It could be interesting to look for a black hole merger where all the matter eventually disappears and our universe is left as a flat cylinder.
This is the “Big Bang” (the Universe is thought to have formed around 10,000 years after the Big Bang) and it’s just one of many different kinds of black holes that can exist (this is just a simple example with no math involved). Of course, black holes always exist as they are, without us.
