I correctly read the article. The usage I provided is
grammatically correct. They made one dual black hole. When they
made the second (and subsequent ones) they made "dual black
holes".

This has already been corrected, first by me, then by another
responder that also didn't follow the entire thread.

Yes sir. My understanding is that they did indeed NOT observe
the jets of particles they expected (?), but instead got a
fireball. Maybe string theory can be tested after all?

Or a dual to a black hole, and one that (apparently) evaporates
is such a short period of time.

Sorry if you think I put out "troll bait".
