Was the Recent Intergalactic Explosion Evidence of Alien Technology?

Solid proof that aliens are about, this must have been a warp core breach.

Wow, that new Guru banner sure looks nice Wolram!

 

[chroot]

Yeah, it kinda makes me jealous that all I have is this lame-o Admin logo. At least until I realize I can vaporize you all if I want. Muhaha. Ha.

edit: and the article is pretty cool, too[/size]

Hey when did that pop up?

While you were looking up.

Oh Wolly, that's just fantastic! You wear it so well

It is nice, but some times i am being serious and people think i am being funny, and vice versa, like this new evidence for ancient space exploration by inteligent aliens, i think i am the first to interpret this information.

That explosion was discovered by the Swift satellite. That's kind of cool (click on "Listen to the Song").

Great some one has run off with the speakers to this PC, i will have wait till i get home.

OK----What caused that explosion?-------any ideas from the parsec's gallery?

It looks like the avatar is your kill and the banner your trophy.

From the NASA page

What came next was a total surprise. Contrary to experience with more than a hundred previous GRBs, Gemini spectra revealed no signs of dense gas and dust absorbing the light of the afterglow. A trace of magnesium revealed that the burst took place more than 9.4 billion years ago, as deduced by the shift in wavelength of the afterglow’s light, and that the surrounding gas and dust was more tenuous than the environment around any previous burst.

. . . .

"Many Swift discoveries have left astronomers scratching their heads in befuddlement," adds Swift lead scientist Neil Gehrels of NASA Goddard Space Flight Center in Greenbelt, Md. "But this discovery of a long GRB with no host galaxy is one of the most perplexing of all."

Might have been the Power Pod that carried the other 90% of the smart genes for the human race.

I am thinking about making a transfer of the avatar and puting it on one of my bikes,
should look cool.

Is it possible that there could simply be dust clouds in the way which would prevent weaker emissions from reaching us, yet allow the emissions from a massive GRB explosion right on through?

Absorbtion lines (or rather, lack of) have evidently ruled that out.

Thanks Danger. I must have been distracted when reading that part. Since they mentioned detecting magnesium and the fact that there was nothing there before (at least not previously detected) how about a neutron star collision?

 

[B. Elliott]

Just found this after doing a little research. The only problem being that this was a long duration one...

Before such a merger, these stars are thought to lead a tumultuous life together, with each in turn exploding as a supernova to become a neutron star. The explosions can kick the pair out of their home galaxy. So in the billions of years it takes the neutron stars to merge, the theory predicts they will lie far away from any galaxy, in empty space.

Interesting link, B. I hadn't heard about that.

That surprised me. Given the gravitational forces involved, I figured that a couple of neutron stars would merge in a matter of seconds.

I thought the same thing till i read that article. Is there any other way for us to detect old neutron stars other than microlensing?

 

[Danger]

I'm ashamed to admit that I can't remember what 'micro-lensing' means; I haven't really read that much about such things in several years.
Neutron stars can be discerned by their gravitational effects upon neighbouring bodies (useless in this case, as there are none), but I don't know that one can differentiate between one of them and a black hole by that method. If it is properly aligned, then you can detect the 'pulsar' signal. Your best bet here is to wait for Space Tiger to weigh in.

The greatest minds on the planet are here on the forum-----someone should be able to figure this out!

Well, count me out of that crowd; I'm just a curious fellow who stumbled into a mindfield. I agree, though, that nothing is beyond the combined intellect of PF.

 

[rewebster]

I'd like to know what the spectral lines are closest to that we know---just how different, besides being in an 'open area' of space, what other qualities did it exhibit?
