Scientists have detected the biggest black hole merger ever known — a gigantic collision from two massive space-time ruptures spiraling into each other — and it could hold evidence of the most elusive type of black hole in the universe.

The merger, which happened on the outskirts of our Milky Way galaxy, produced a black hole roughly 225 times more massive than the sun.
