Newly discovered black hole is so large, it shouldn’t exist

(CNN) - Scientists have discovered a “monster black hole," but they said it’s so big that it shouldn’t actually exist.

It’s a stellar black hole, which is the kind that forms following the death or explosion of a massive star.

Before this discovery, researchers thought the size limit for black holes was less than 20 times the mass of the sun, but this black hole, known as LB-1, appears to debunk that theory.

Its mass is 70 times larger than the sun, according to the Chinese Academy of Sciences.

No worries, though: This monster is 15,000 light years away from Earth.

The findings were published in Wednesday’s edition of the journal Nature.
