Discover the "death children" of the Big Bang

(NLDO) - Scientists have just discovered the "dark legacy" of the Big Bang: A herd of monsters billions of times larger than the Sun.

According to SciTech Daily, an international research team led by Stockholm University (Sweden) has found an incredible number of "monster of all monsters" black holes from the early universe. It is the "zombie" state of the first objects born after the Big Bang event.

These black holes appear to be permanent traps in space-time, forever swallowing anything that passes nearby.

They are the largest of the monster black holes, millions to billions of times more massive than the Sun, and like hibernating dragons, they will wake up and devour anything unlucky enough to pass by, then burn up like shining beacons.

Scientists have previously talked about this type of black hole, which existed during the "Cosmic Dawn," the first billion years after the Big Bang.

They often exist as active black holes at the centers of large, bizarre galaxies.

“Many of these objects appear to be larger than the initial masses we thought possible at this time, either they formed very massively, or they grew extremely rapidly,” said co-author astronomer Alice Young.

According to the paper published in the scientific journal The Astrophysical Journal Letters, the team used years of Hubble telescope data to measure changes in brightness of ancient galaxies, which are clear signs of black holes.

Not only did they discover more black holes than expected, but also clues to their origins.

Some of these ancient black holes likely formed from the collapse of massive, pristine stars in the first billion years after the Big Bang.

These children of the Big Bang – a very extreme but purely material type of star of the early universe – could only exist in the very early period of the universe, because later generations of stars were “polluted” by the remnants of previous generations of stars.

Those extreme, supergiant stars are short-lived, quickly merging, exploding, and turning into giant primordial black holes within the first few seconds after the Big Bang.

With this new information, more precise models of galaxy formation can be built and help humanity understand more about the violent past of the "newborn" universe.
