At the edge of known area are quasars. The majority of galaxies have a SMBH, including our own galaxy, but for quasars to be so powerful their SMBHs must have become very big really rapidly. Weve long believed their development included an unique set of circumstances, however a brand-new study shows that early quasars might have formed purely from cold dark gas.
The biggest secret about quasars is their youth and power. In the previous couple years, astronomers have found quasars so far-off that they need to have been active less than a billion years after the huge bang. Their extreme power indicated that they need to be billions of solar masses in size. How could such huge objects form so quickly in the early universe?
The most common theory has been that they were formed from the remnants of supermassive stars. These black holes then ended up being the seeds of early quasars. Possibly to rare to account for all the far-off quasars we see today.

In the early universe, gravity and expansion developed the seeds of galaxies by developing clusters of gas linked by filaments. Through this procedure, a billion solar mass black hole could form over the period of simply a few hundred million years. Whats more, this procedure was relatively typical, and didnt need the unique conditions of other SMBH models.
So it appears the very same process that created the clusters of galaxies we see today also formed the seeds of supermassive black holes and the first effective quasars. Which assists explain why early quasars are so typical, and why most galaxies have supermassive great voids.
