Modeling supports one view of massive black-hole creation in early universe. The appearance of supermassive black holes at the dawn of the universe has puzzled astronomers since their discovery more than a decade ago. A supermassive black hole is thought to form over billions of years, but more than 2 dozen of these behemoths have been sighted within 800 million years of the Big Bang 13.8 billion years ago.
In a new study a team of researchers add evidence to one theory of how these ancient black holes, about a billion times heavier than our sun, may have formed and quickly put on weight...
