Observed Gamma Ray Bursts Occur 1 Per Day. So What About The Unobservable Ones?

Question

Since The Bursts Are Given out In A Narrow Cone
And How Many Black Holes Are There In The Universe Currently?

Answer 1

I am researching my answer to your question and realize we do not know very much about it, from saying there is only 1 burst per 65 days in 2002 to a lot more as we learn . You probably know more so lets hear your theories instead.What I found so far........

------
Gamma-ray bursts are the most luminous explosions in the Universe, and their origin and mechanism are the focus of intense research and debate. More than three decades after their discovery, and after pioneering breakthroughs from space and ground experiments, their study is entering a new phase with the recently launched Swift satellite. The interplay between these observations and theoretical models of the prompt gamma-ray burst and its afterglow is reviewed.
----------
There will be a conference to discuss this and abstracts are being featured in that conference.
33rd annual European Physical Society Conference, Rome, 2006.

As for black holes, we are also still learning. Here are some links.

Answer 2

The number of gamma ray bursts that are missed and others obscured by dust and celestial objects could be very high.
The origin of gamma ray bursts has not been determined.
Speculation says that they may be merging black holes.
Since I do not believe that black holes exist this solution is out.
If a maxed out neutron star can not co lapse to a black hole something else must happen to it.
If the space displaced from a neutron star on collapsing [the space that supports its existence] it may be transformed into pure energy in the form of gamma rays.
If this transition took place in one twelve-thousandth of a second it could produce just such a result.

Answer 3

These`re the only ones intercepted/detected with the existing equipment level & technology we have today , but nobody for sure will tell you that these (intercepted) are the only ones around in existence in the whole universe.
About the Black Holes , let alone tracking their count or position , even the ones we claim that we know their existence/location for sure , noone ever saw them physically/visually ; the reason : even light cannot escape a black-hole due to its immense gravititional pull/suction. The only means to detect them is , the hyper-activity(swirling) and commotion around them with totally dark centre ( mass disappearing in to the unknown dimension( may be to the SEED of time & space) - we call it point of Singularity .

Answer 4

"...So What About The Unobservable Ones?..." What about 'em?

"...How Many Black Holes Are There In The Universe..." No estimates have been made.
