Powerful Blast Confuses Astronomers
eldavojohn writes "Astronomers are still speculating as to what could have caused an abnormally strong five millisecond burst to be detected six years ago when it completely saturated their recording equipment. From the article: 'The burst was so bright that at the time it was first recorded it was dismissed as man-made radio interference. It put out a huge amount of power (10exp33 Joules), equivalent to a large (2000MW) power station running for two billion billion years.'"
I heard this story on NPR yesterday. I'm inclined to believe that it was...
Absolutely nothing.
It happened one time, six years ago, for less than five milliseconds, and no one else in the world can corroborate that it happened. To me, it sounds like either an equipment malfunction or something much more mundane that interfered with the measurement for that split second in time. Science is about repeatable, testable, observable results, not one-off flukes.
Now, having said that, I think it's probably worthwhile to see if it happens again. As the article says, "The astronomers estimate on the basis of their results that hundreds of similar events should occur over the sky each day." If that is the case, then get to looking, and maybe I'll change my mind once they have more evidence.
Until then, though, let's not get so caught up in the coolness of the possibility of something we've never seen before that we don't do due diligence and make good science.
Did it come from Uranus?

So, something happened 6 years ago, and nobody knew what it was.
They still don't.

It's so obvious what it was... A long time ago, in a galaxy far far away, the rebel fleet successfully attacked and destroyed the first Death Star. The energy from the explosion finally got here. Duh...
This tragic explosion was the result of idiot low level managers ordering ill-advised experiments with all of the control rods pulled out of the Dyson Sphere.
Yea, the colonel was drunk and forgot that the Deathstar's beam dissipates as the cube of the distance from the planet. Clearly out of range and making a fool of himself. Vader would not be pleased.

Perhaps the signal was manmade. And if the signal saturated the detector, then it's even harder to judge the waveform and deduce what caused it. TFA says the frequency shifted during the pulse. That's not uncommon in the pulses used in radar which may been on a passing plane or satellite. Even if the frequency bands are different, the harmonic effect means that a strong source of one frequency may appear as a weak source of a different frequency. Either that, or someone made microwave popcorn on a lonely night and wouldn't confess.
Of course, I've not seen the data and IANARA.
Two wrongs don't make a right, but three lefts do.
I picked up the same thing on my instruments.. it was just a video clip of Hitler introducing the 1936 Olympics... that's all. Nothing to see here. Move along.
nonsig. unsig. desig.
It was only the end of a war.
If the signal is "exactly" 5 milliseconds (and as an engineer, my first question is "to what precision?") that would seem to point to a manmade source. Or at least, it's silly to assign significance to it, since the "second" unit of time is an arbitrary measure, not naturally derived from physical constants.
A different species observing the phenomenon might say, "Wow, a large signal. But it's only 7.49182 blergs in duration. Obviously, it is a natural phenomenon."
Xenu Cometh!
... that was just Krypton blowing up, of course.

The assumption likely is that the energy is radiated in all directions. This puts the power varying as 1/d^2 which is a very small number when d gets rather large. The consequence of this is that if we get a signal of magnitude "x" then one would infer from this assumption that one must multiply by d^2 in order to calculate the energy at source.
If this energy was focused as it is say by a laser then the original power can be considerably lower. A parabolic lens will also focus the radiation but not nearly as well as a laser. One way this can be focused naturally is to simply put a large gravity well in the path the light takes between source and us.
The phenomenon may be little more complex than a gravity well which passed between us. If this gravity well is moving at the right speed then the period of time the energy remains focused can be short. It would be very interesting to find the gravitational lens (if this is what happened) is actually in orbit and we manage to pick up the pulse again.
The thing is with the proper focus all the assumptions of the size of the burst just fly out the window.
I wonder if this will get a mention in this semester's Introduction to Astronomy class at Berkeley.
So this is the Little Bang.
And I don't understand why do they have to guess before doing some serious research. They have given to possible explanations, collision of two nuetron stars, that sould produce radiation in higher frequencies (gamma ray, see Gamma Ray Bursts) and black hole evaporation, which shouldn't be that intensive (unless when the black hole is spinning, the energy released should be 11 orders of magnitude higher, see Black Hole Evaporation).
Of course, I might be wrong. First, I'm not an astronomer. Second, I understand most things about black holes and nuetron stars suppose to include aspects of relativity and quantum theory, so both should not be applied to them... (as they contradict)
I had my CB amp cranked to 11 that day. Sorry bout that.

You know those spectacular space battles you've been watching on TV all the time? Well now you know what happens when an Imperial huge-mega-ultra-destroyer-obliterator fires... and misses. Some poor planet thousands of light years away gets powdered to dust. We're lucky that was a shot from a tiny-wee-shuttle, from thousands of years away these cause just a 5 ms blip.

It was a stargate Wormhole beam now we have a way to cover them up now that we now what to look for.
If the object releasing the energy is rotating. This happens in pulsars, for example, and should happen when a massive rotating star collapses into a black hole, and in astrometric binary stars (when only one partner is actually a star, the other is a dead star), with an accretion disk.
From TFA:
The amount of this dispersion, the astronomers said, indicates that the signal likely originated about three billion light-years from Earth.
Maybe it was from the death star exploding a long, long time ago in a galaxy far, far away.
We don't have atheists like in your country... we do not have this phenomenon. I don't know who's told you that we have this.
Scientists suspect the pulse to have emanated from the black hole 604T5ECX in the Saggitarius-arm.

Was the moon, by chance, anywhere in that area of the sky, and was there a monolith present?

It was probably a radar pulse from a radar equipped object flying overhead.
Obviously the power of the signal is pretty high, but something flying close overhead could possibly cause a signal like that on equipment calibrated to be observing radio frequencies at trillionths of a watt. I am sure there is not a linear correlation to the sensitivity of the equipment to varying power observations.
To test my hypothesis, I would figure out what frequency or frequencies were observed at the time, and compare them with know earth based frequency usage. If one happens to be an aircraft or satellite radar, you have your answer.

Your fantasy owuld be funny were it not just part the cause of so much mayhem and misery in this world.
The explanation is simple -- it was our evil alien overlords sending the order to launch the 9/11 attacks. The evidence of the true extraterrestrial origins of the attacks, including the "767s" that hit the towers, are hidden away in area 51.
No, Bush had nothing to do with the attacks -- OPEC and Bush are working together to suppress the alien cold fusion technology which would of course devastate both their respective interests. As for Bush's sudden interest in space exploration, that's the true War on Terror; the Iraq invasion is just to trick the aliens into thinking we think Saddam ordered the attacks. In fact, Saddam was hanged for wanting to get back at Saudi Arabia by releasing the aliens' cold fusion technology.
Also, most "9/11 conspiracy sites" on the internet are put there by the government to suppress all discussion of the extraterrestrials and train the american consumer to think of anyone who doesn't accept the official version of the attacks as bush hating liberal whacko sheeple.

Because it's something new that they didn't understand. Hence, in the literal form, news. New data! Something that might be a deep and meaningful key to the universe! Or statistically unlikely interference from an old bit of stray noise. I wouldn't say anything that's science is necessarily news for the masses--some people simply don't care when we discover something new unless it impacts their work day or family life.
But this is news for nerds, not news for Thoreau.

I understand that some gain psychological comfort from their membership in cults, as well as from believing in deities and idols It's easier than facing facing reality, such as death, etc. But why is it so difficult for people to understand that such things are not only imaginary, but completely unnecessary?
Astromoners can usually work out how big an object was, but how fast its brightness changes. The reason being nothing travels faster than light, so if an object varies over t secs, then it must be smaller than 2t/c meters. So we have a 5ms blast, so the object that made the blast smaller than 1500 km across. Combined with the large energy, 1e33 J or 1e16 Kg of matter converted. Not much else could make such an explosion, except a neutron star. Still the blast wasn't that powerful, i'd except a neutron star colision to release maybe 1/1000 of a solar mass as energy, this was a hundred millon times less powerful. So maybe a super starquake (not the great spectrum game, but like an earthquake on a neutron star), rather than a neutron star colision.
After the blast, astronomers from universities across the country were seen wandering dazedly through the halls and campus greens. The sky-gazers did not seem to know where they were, nor what they were doing there. Some astronomers were found in a parking lot below Mt. Palomar, with car keys in their hands, unable to locate their own vehicles. Some had to be given emergency oxygen because, not knowing their altitude, they had forgotten their oxygen masks.
Emergency psychiatrists were called in to deal with the situation.
"I've never seen anything like it," said Dr. Itznada Seegar of the Federal Emergency Psychiatric Adminstration. "These astronomers are, to put it in layman's terms, dazed and confused. You can use that movie reference, right?"
Dr. Adeep S. Komplacs posited a new cosmic psychic ray. Surrounded by clouds of THC byproducts, he remarked, "I've heard of cosmic rays, but this was one cosmic cosmic ray, dude!"
As things slowly return to normal, said one Astronomy Department head, "Thank God the effect is wearing off. Now we can get our astronomers' heads back in the clouds."
Towards the Singularity.
To me that suggests that, while the actual event at the location it occurs can be reasonably said to have lasted less than five milliseconds, the actual recording of data lasted longer than that period of time, and there are certain identifiable characteristics in the data that an astronomer would expect to find, both of which seem to strongly suggest that the event really did occur.
No, what happened first was the astronomers analyzed a piece of data (actually a large mass of data). They were looking specifically for a specific signature. They then found one piece of data in that mass of data that had that signature. They went looking for a signature and found it. How do we know that piece of data was real, and not just an accident?
The thing you have to realize is that all experiments have flaws, and all experiments have errors. With only one piece of data it's likely that this is an error. The fact that there's an explanation for the data doesn't really count. They went looking for that signature in the first place.

the power and length of this signal are very odd, but the oddest thing to me is that it only affected astronomers!
3 billion years ago (+6!) an advanced civilzation attempted harness the power of the perfect particle. Particle 010, the Omega Particle. This civilization no longer exists (hence we haven't seen another blip) and the space around it is completely destabilized - preventing us from getting even close enough to figure out exactly what happened.

Something freaky happened on that day. I woke up in the middle of the night because the light in our bedroom was on. Flicking the light switch didn't turn off the bulb and so I just went back to bed puzzled and a little scared something had shorted. But in the morning the light worked again.
Mmm, maybe it had something to do with the big hole they found in the universe recently?
Sig pending!
I'm surprised that this would be a huge amount of power for astronomers. The average star should output that much power probably every few seconds. Probably not in the RF band, but still
Knowing the kind of people who get into astronomy, even a soft jab usually knocks their lights out.
Sorry, we had had a few and were just having a quick game on the scope and some prick hit some equipment. We didn't think anybody would notice. It's all a bit embarrassing really and we don't do that sort of thing anymore. But if anyone cares Parkes won by three wickets and 34 runs.

Keep in mind that milliseconds are a human invention; if the signal was an extra-terrestrial message, the fact that it lined up with human time measurements would be a coincidence (and an unlikely one at that). This sounds more like a "human creation" - ie, either of the two possibilities that NeutronCowboy mentioned.
What i wonder such a huge blast would have side effects.
Lots of dust atoms etc outthere in space might react on it.
