Black hole formation as seen by a distant observer

I've read in several places that from the PoV of a distant observer it will take an infinite amount of time for new matter to fall past the event horizon into a black hole, due to time dilation effects.

This seems to imply that once a black hole is formed, its mass cannot actually grow any further as considered by most observers in the universe. Is that right?

  • $\begingroup$ @dmckee I do not see it as a duplicate because it asks about growth rather than formation. $\endgroup$ – Anixx May 26 '14 at 23:01
