Ancıent Black Holes Have Revealed a Mystery at the Edge of Tıme and Space

 Scientists have just solved a long-standing puzzle concerning ancient supermassive black holes and the galaxies they inhabit by observing very luminous objects that existed 500 to 1 billion years after the Big Bang.

Nothing can escape the gravitational attraction of a black hole, not even light. Black holes of all sizes and ages have unresolved mysteries, but the supermassive black holes that existed in the early universe are particularly perplexing.

For instance, it is unknown how these huge objects, some of which reached masses one billion times that of the Sun, were so enormous so early in the history of the universe. Furthermore, scientists have long wondered what prevented those first growth bursts and pushed supermassive black holes towards a more symbiotic evolution with their host galaxies.

Researchers for Italy's National Institute of Astrophysics, led by Manuela Bschett, a postdoctoral researcher at the Astronomical Observatory of Trieste, have now discovered the surprising revelation that extraordinarily potent winds from early supermassive black holes likely hindered their expansion.

According to research published in Nature, Bschett and her colleagues identified 30 quasars as the final stage of "black hole feedback," a process crucial to the formation of modern galaxies, including our own Milky Way. Quasars are extremely bright objects that are frequently found at the centers of nearby galaxies.
