Black hole 12 billion times bigger than Sun swallows science theory

Scientists have discovered a black hole so big it just swallowed up their theory about how big they can grow.

Scientists are now trying to figure out why a black hole formed about 900 million years after the Big Bang doesn’t fit the current theory about how big it should be. With measurements indicating it’s 12 billion times the size of the Sun, the black hole challenges a widely accepted hypothesis of growth rates.
