Neutron stars may be too weak to power some gamma-ray bursts
Science Centric ^ | November 3, 2010 | Unknown

A gamma-ray burst is an immensely powerful blast of high-energy light thought to be generated by a collapsing star in a distant galaxy, but what this collapse leaves behind has been a matter of debate.

A new analysis of four extremely bright bursts observed by NASA's Fermi satellite suggests that the remnant from a long-duration gamma-ray burst is most likely a black hole - not a rapidly spinning, highly magnetised neutron star, or magnetar since such a burst emits more energy than is theoretically possible from a magnetar.

'Some of the events we have been finding seem to be pushing right up against this total limit for a neutron star progenitor system,' said S. Bradley Cenko, a post-doctoral fellow from the University of California, Berkeley.

It’s minor bumps of the branes. These guys have it all wrong. Remember, I said it first.

This should not be a problem. Obama will throw a few taxpayer dollars at one of his friends to start a green energy company to power the gamma-ray bursts...

Another thing to thank the Almighty for: there isn’t one of these things within 1000 light years of us.

Wait...from 2007:

Astronomers pinpoint origin of the most powerful magnetic bursts

*********************************EXCERPT********************************

Science Centric | 22 September 2007 13:39 GMT

University of Arizona astronomers have pinpointed the origin of powerful bursts from nature's most magnetic objects. The bursts are from 'magnetars,' some of the most enigmatic objects in the universe. Magnetars are a type of neutron star, which are superdense stars that pack the mass of a sun into a body the size of Manhattan Island. Tiny magnetars possess magnetic fields that are at least 100 trillion times as powerful as Earth's magnetic field. They occasionally produce powerful bursts, hurling high-energy radiation cascading across space. The origin of these energetic eruptions and the strong magnetic fields is a mystery.

Indeed. On a related note, neutron stars have got to be some of the most fascinating objects in the universe. Just contemplating their physical properties is mind blowing.

I used to think gamma ray bursts were from the other side, or from holes burned right into or through the fabric of space, briefly shinning into our dimension like a search light...I’m not so sure now.

Paging Valerie Jarret: " He knows exactly how smart he is. ..."

A gamma-ray burst is an immensely powerful blast of high-energy light thought

Ooh Barry-O...

Ooh baby, I hear how you spend night-time:
Wrapped like candy in a pure blue neon glow.
Fade away and radiate.
Fade away and radiate.
Ooh baby, watchful lines vibrate soft in brainwave time.
Silver pictures move so slow.
Golden tubes faintly glow.
Electric faces seem to merge.
Hidden voices mock your words.
Fade away and radiate.
Fade away and radiate.
Beams become my dream.
My dream is on the screen.
The beams become my dream.
My dream is on the screen.
Dusty frames that still arrive
Die in nineteen fifty-five.
Fade away and radiate.
Fade away and radiate.
The beam becomes my dream.
My dream is on the screen.
Fade away and radiate.
Fade away and radiate.
Fade away and radiate.
Fade away and radiate.

(Fade Away And Radiate Lyrics Artist(Band):Blondie)

A Barry-O burst is an immensely powerful blast of high-energy bullsh!+

The really weird thing though, is this triple ping came in BACKWARDS 9, 8, 7.

If you fell off a chair 1 meter high on a neutron star, you'd hit the surface at 4.3 million mph. Splat!

And if you built a rocket to fly off of a neutron star, it would need an escape velocity 1/3rd the speed of light.

Cool stuff!

Of course, this is all hypothetical. Life on a neutron star would be very, very brief.

Life on a neutron star would be very, very brief.

And that is why those inhabitants of neutron stars, the neutrinos, escape in untold numbers and disguise themselves as dark matter.

And they aren't just border creepers.

They violate your personal space.

AND YOU DON"T EVEN KNOW IT!!!

A neutron star is so dense, a teaspoon of its material would have a mass of about 1000 times that of the Great Pyramids..

And if you study Afrophysics, you would know that Barry-O is so dense, light bends around him. So dense it takes George Soros a thousand pyramid schemes to support his (m)ass.

Nice job on hijacking this guys thread with all your slick humor.

I bet if ya look really hard, you could find an Obama thread to post this juvenile BS on.

Thank you for your kind reply.

I would much rather do web searches on the formation of neutron stars. These threads always lead me to explore the subject more fully.

It’s amazing the things you can learn and ponder on.

I’ve seen a couple of those Obama threads and I always think “The things you see when ya ain’t got yer log chain...”
