Largest Black Holes in the Universe | How big can they get? What's the largest so far detected? Where does an 18 billion solar mass black hole hide?

We've never seen them directly...

yet we know they are there...

Lurking within dense star clusters...

Or wandering the dust lanes of the galaxy....

Where they prey on stars...

Or swallow planets whole.

Our Milky Way may harbor millions of these black holes...

the ultra dense remnants of dead stars.
