Scientists showed how the first quasars formed

A model developed by researchers reveals how the earliest quasars might have evolved fewer than a billion years after the Big Bang. They demonstrated that large gas fluxes may produce supermassive black holes.

Supermassive black holes in the early Universe

The University of Portsmouth has developed a model that depicts how quasars arose in the early Universe. Each of these objects represents the Galaxy's active center. A supermassive black hole sits at it's heart or the center of it. These things are now primarily expanding as a result of the merger of smaller singularities.

The only issue is that we know of at least 200 quasars that occurred fewer than a billion years after the Big Bang, which marked the beginning of our Universe's existence. The period of reionization has not yet come to an end. Supermassive black holes would not have formed naturally since the first stars had barely begun to exist in space.

For a long time, scientists were unable to reconcile the conflicts between the present method of supermassive black hole development and the presence of quasars at such a young age. And now, a new process for their development has been discovered.

First quasars formed from gas

Scientists have long known that during the so-called "dark ages," when the Universe's age was only measured in hundreds of millions of years, up to 100 thousand unique stars may exist in it due to the collision of cold gas flows. Scientists chose to investigate whether these processes may be more extensive at times.

It was discovered that in a cube with a side of 1 billion light-years, there must have been such a powerful collision of gas masses that its substance was compressed. Giant stars with masses ranging from 30 to 40 thousand Solar masses were produced. They burst very instantly, giving birth to black hole embryos.

The quasars then appear to have grown by directly consuming the surrounding stuff. The presence of young quasars in the early Universe is eventually explained by this result. However, it has unintended consequences.

We're accustomed to finding supermassive black holes in the core of a galaxy. The new model, however, suggests that the oldest of the quasars may not be surrounded by any star system. Over time, luminaries may begin to assemble around such a "primary" quasar.
