Then how come we don't observe any white holes, or white hole
candidates? There are gamma rays, yes, but we can't see what kind of
object they are coming from because they come from outside our galaxy.

Maybe I'm wrong but I think that Swift, in more or less one minute after
detecting a GRB, can observe the source and communicate the Earth
observatory the coordinates of th GRB emission.
So this time Bert will have immediately a proof of how is bad to eat lots of
Italian meat balls and after that thinking about white holes...
