o.k. I am so new to this that I make new borns look old but I have such a huge interest in the universe around us that it makes me giggle like school child every time I look up and try to see as deeply as I can into the night sky. It boggles me to the point of losing my mind.
My question if it can be construed as such is, Where does the matter and gasses that get caught up in a gamma ray burst end up? Could a gamma ray burst posibly be explained as a stunami of the cosmos? Where are the ending points of the Bursts and what is left there?

I'll leave the answers to someone else, but I will say welcome to BAUT glenn II.

And I will offer the hand of Welcome... Yes I have lost my mind and a few friends by looking up with a little giggle They just have no idea or, if they do. Do not care.
I do not know where your view of the sky is from and if you can access a telescope or not. Getting away from city light pollution can only enrich your experiences.
Your question is interesting and impossible to be absolute about. We can 'see' 13.7 billion light years. They say. So any Gamma ray bursts that we see has happened closer to us than that. According to me. What reaches us is just the smallest fraction of the energy that was ejected... how far it goes would be dependant on the not being stopped by any thing in the path. Space would be accurately described as empty. Empty does not make it devoid of all matter.
The Gamma Ray Burst might have been born from a star collapse or destruction of the same as it entered or became a Black Hole. I am very pleased this does not happen often around here. When you ask ' What is left ?' Do you mean as its destination furthest point. Or at that SMBH starting point. And my answers would be...a almost unmeasurable blip in the back ground tempreture of space... or a SMBH.

No actually what I meant was where does all the atmosperes and gasses caught in the way of the burst end up..
Why have we not been able to detect the masses that must be gathered up and depsoited by the burst?

Welcome glenn II. First,don't lose that awesome feeling about the universe.

Second. The best models of gamma ray bursts indicate that they are in all liklihood of two different origins.
1.Some are thought to be due to neutron star mergers, spiraling in in a few seconds, and are of short duration. The vicinity of these is usually low in matter and dust, and it is ionized as they do so, later cooling back to gas.
2. The second source is supernovae. The explosions are axisymmetric, meaning they blow their tops and bottoms off, and the gamma rays escape predominantly in a beam along the axis of symmetry from the poles. Indications are that beaming factors (collimation in starspeak) are around a factor of 10,000. These are of longer duration. Matter and gas is definitely blasted away here, and was observed leaving the vicinity of SN1987a at around 9/10 the speed of light (0.9 c). The rest of the blast usually forms a barrel-shaped remnant, whether of type 2 (core collapse), or type1a (white dwarf with bloated companion).

There are some oddities.
1.Because of the beaming, most of the bursts don't come "this way" and supernovae go off without us seeing a burst.
2. Some long bursts have not had an optical counterpart, but it's possible it was a dust obscured infrared signal we did not see at the time.
3. There is nothing to preclude a neutron star from circulating through your home galaxy (unless you're an alien), the Milky Way, and crash through the roof of your house during the night creating a small burst, because they do travel up out of the plane of the galaxy's disk and then back down again...except for the fact that our very best instruments and astronomers have determined that there are no neutron stars closer than ~ a few hundred light years, and that's a few thousand years of travel time away. So you can sleep at night and still think the sky is awesome... pete

Ahhh thank you. Most of that I already knew but the point that came across to me concerning where it all goes was made very plain to me. Again thank you.

I have very little desire to be caught up in the event horizon. Unless of course I was able to observe and not be pulled apart atom for atom. |Will the black holes be the last to explode, blibking out the lasyenergy in the universe?

my apologies for not clearing up my typos.

glenn II Ah,but you can clear up your typos. Sign in at the top of the offending thread with your username and password. Then when you go to your post, you will have a second "button" at the bottom of it....EDIT. Click on the edit, and you can fix (and only you can fix...) your typo. I often post and then search for a google link, come back and edit my post with the link. You may NOT really edit your content to say something else or a mod will censure you...but fixing typos is common, and increases the readability, and reliability of the forum. Enjoy. pete

If they're close enough, they're likely turned to highly energetic plasma.

If I set the budget, we'd have Ares and more. Unfortunately, I don't set the budget, and Ares is just too expensive and too far out for us to accomplish our goals within the budget we were given.

If we halt the ISS, all versions of Ares, and transport Orion and Altair aboard DIRECTv3's Jupiter family of Shuttle-Derived Launch Vehicles, we just might make it back to the Moon by 2020.

Just about that question, I think the idea of a "tsunami" could easily be used as a simile, because a tsunami is a high-energy event, and is used in other contexts, like election "landslides" (metaphorical again) for example. So in a loose sense, why not?

Well, my problem with it is that a GRB is a very sudden event, and then it's over. A tsunami appears quickly, but then it keeps coming and coming....
