Abstract:  The source of gamma ray bursts has been somewhat 
perplexing to scientists.  The bursts are as varied as 
flowers in a field.  Some short, some long, some leaving 
visible residue, some not.

Gamma Rays are very high energy electromagnetic radiation.  

What follows from joe is essentially guesses in the form of 
hypotheses based entirely on the apparent fact that the 
cosmos is composed of essentially only of two items:  dirt 
(mass) and superdirt (radiation).

From that apparent fact, we must create all the systems of 
visible and invisible phenomena that beset the human eye and 
his instruments to explain what is going on all around us.

Particle physics may face the same issues of simplicity.

But let us begin:

For starters there is a gamma ray burst called a 'hybrid' 
GRB.

Hybrids don't leave a marker of light in space.

Why not?

The only explanations that joe suggests are two:

1)  The hybrid gamma ray bursts come from or are caused or 
effected by a black hole or a black hole system (binary or 
higher) and as such all normally visible radiation is 
retained within the black hole or is behind the event 
horizon itself, leaving nothing to observe.

2)  The hybrid gamma ray bursts have normal novadic sources 
but the high energy radiation coming out the zero gravity 
port has passed close by another hypergravity object and has 
been substantially bent by the second warped spacetime 
object.

We get the burst, but don't notice the real source far away.  
This one should be sort of easy to confirm or deny as there 
would be a timely novadic event somewhere probably but not 
necessarily close to the novadic event, either shortly 
before or shortly after the gamma ray burst.   

3)  The third hypothesis is that the GRB may have occured 
behind the event horizon of a black hole and was simply 
gravitationally warped around it, but the event horizon is 
still obscuring the source of the GRB leaving nothing 
visible to the recipients of the Gamma Ray Burst. 

A child must come from its parent.

A child process must come from its parent process.

It is helpful probably to match up the energies when looking
for the source for cosmic events.  (see "Time as a field" chapter)

Gamma Ray Bursts are probably sourced within the energies
found in Black Holes.  

Black Holes vary in size therefore the Gamma Ray Bursts will vary
in distributed energy.

note:  Scientists have recently (Nov 2007) varified their suspicion
that Gamma Ray Bursts are sourced, near, around, or in, ultra high
gravitational objects (black holes).
