Scientists witness massive gamma-ray burst, don't understand it
Christian Science Monitor ^ | November 21, 2013 | By Pete Spotts, Staff writer

An exploded star some 3.8 billion light-years away is forcing scientists to overhaul much of what they thought they knew about gamma-ray bursts – intense blasts of radiation triggered, in this case, by a star tens of times more massive than the sun that exhausted its nuclear fuel, exploded, then collapsed to form a black hole.

Last April, gamma rays from the blast struck detectors in gamma-ray observatories orbiting Earth, triggering a frenzy of space- and ground-based observations. Many of them fly in the face of explanations researchers have developed during the past 30 years for the processes driving the evolution of a burst from flash to fade out, according to four research papers appearing Friday in the journal Science.

“Some of our theories are just going down the drain,” said Charles Dermer, an astrophysicist at the Los Alamos National Laboratory in New Mexico and a member of one of the teams reporting on their observations of the burst, known as GRB 130427A.

The event, dubbed a long-duration gamma-ray burst (GRB), is typically seen in the distant, early universe, Dr. Dermer said during a briefing Thursday. This one was much closer. And while typical long-duration bursts last from a few seconds to a few minutes, GRB 130427A put on its display for 20 hours.

The event's duration, relatively close proximity, and the range of observatories in space and on the ground that could monitor it at a range of wavelengths has provided scientists with an unprecedented opportunity to explore the workings of one of the more extreme ends a star can inflict on itself.

The encouraging news: Traits seen in the gamma-ray emissions from initial burst through the afterglow compare favorably to the traits seen in the behavior of gamma rays in more-distant, long-duration bursts.

"I don't know why he would have the response you think he does."

I was using poetic license - His response would be more like Job Chapters 38 - 41.

Job also uses poetic license.

I also noticed that mankind can now answer "yes" to some of the questions God asked of Job.

We also have knowledge of God's creation which isn't in the Bible.

I have a doubt that the orientation will be purely random.

Certainly, planets revolving around a star generally rotate around poles that are roughly perpendicular to the plane of their orbit. So the polar alignment of planets bears some relationship to the sun they orbit.

Stars too bear a relationship to the supermassive black hole at the center of a galaxy. Stars orbit in a Galaxy. So stars too bear a spacial relationship to the galactic center.

Are there any hypotheses that seek to predict the orientation of the poles of a black hole, i.e. the gamma ray jets at either end, that corresponds to its spacial relationship to the the galactic center, or for that matter any other celestial object?

I don’t know, but when Betelgeuse goes supernova, I hope it’s pointed at 90° to US.................

Here, due to some peculiar forces, the nebulae axis of the nebulae aligns with the plane of the Milky Way.

This is exactly what I was thinking of.

As our sun rotates around the galactic center, there is an excursion above and below the center plane of the galaxy, which our sun crosses, if I remember correctly every 250 million years or so. This happens because the plane of the Milky Way is a "Fedora" shape.

Some have corresponded the crossing of the galactic center plane with mass extinction events.

The orientation of black hole axes with one end toward the galactic center and the other end pointing out, would tend to make the center of the galactic plane the most likely location for a gamma ray burst that exits the galaxy.

With this particular burst lasting 20 hours, it makes an object crossing the galactic center and even greater risk of exposure to a burst than previously thought.

Why do such planetary nebula orient in this center to out direction?

Obviously due to galactic warming.

Is due North the “direction pointed forward” that we are traveling? Realizing how the sun is barreling through space with us in tow and all the planets down to the Ort cloud is hard to fathom. Astounding universe.

If a spaceship leaves Earth into deep space and just sits there does the sun and gravity tow them along with everything else or do they have to fly fast enough to keep up??

Honestly, I just hope that there are none of these these things waiting to go off that are pointed at us, that would be a very, very, bad thing, if it were relatively close.

And so they should just give it up?

Personally, I believe that God wants us to know as much about His universe as possible. It’s stunning to consider how much we actually do know, and very exciting as to how much more we’ll learn.

It was just planet Craptomite exploding.
