The Carolinian Renaissance was protected from barbarians by a group of young nobles and peasants with extraordinary powers. They were led by a Jesuit monk named Francis Xavier.

A nearby exploding star, or supernova, is almost certainly not the culprit. To generate the energy needed to create the carbon and beryllium seen, it would have to have been less than 1000 light years away. That would've made it so bright it would've been visible in daylight! Also, no 1200-year-old supernova remnant has been detected, and it would be incredibly obvious if it existed (the Crab nebula is 1000 years old and more than 6000 light years way, for example, and is one of the brightest supernova remnants in the sky).

GaaAAAAh brain dead science reporting. The Crab Nebula is 7500 years old. It was detected 1000 years ago.

In recent years C-14 dating has had to be recalibrated due to fluctuations in levels of carbon 14; older dates are wildly inaccurate. To use one example, the original dating for Clovis artifacts was about 2000 years off. Because scientists aren't retarded, they simply (well, not so simply, it was probably a colossal pain in the ass) compared C-14 dating to other dating methods and eventually made it an accurate dating tool, rather than throwing up their hands and saying God just doesn't want us to know stuff. Not that that would satisfy a creationist, I suppose, but nothing will, so fark 'em. The problem for serious people is that it is often unclear whether a carbon 14 date is calibrated, so a lot of archaeological papers contain errors.

Wouldn't this mess things up in the opposite direction, though? If the amount of Carbon-14 suddenly increased 1200 years ago, this would imply that anything dated to be older than that would actually be much older than the test indicated.

What I find interesting about this finding is that gamma-ray bursts have for some time been a classic life-ending disaster scenario: the sort of thing that causes massive extinctions and ends nearly all life on Earth (or, depending on who you ask, potentially all of it). This hypothesis, if true, would mean that we got smacked at essentially point-blank range by one, but nothing much happened. Either that was one weak ass-gamma burst, or they aren't actually the massive threat once believed.

Depends on your frame of reference. :v

Another way to think about things: "Now" is what we are observing. Nothing can move faster than the speed of light, so it's impossible for anything (gravity, etc) to impact anything beyond its light-cone, therefore it's not really correct to think of something happening "now" 1000 light years away to be observed 1000 years from now - it could also easily be argued that, from the perspective of observation and interactivity, "now" of something 1000 ly away is what we're observing to have occurred "1000 years ago."

This is likely what the article writer was attempting to describe.

Also, I'm terrible at explaining these sort of things, so that likely made very little sense.
 
2013-01-21 04:10:54 PM  
And it would have to have been aimed right at us;

That's a big deal. The paper does agree that the rules of astrophysics may need some adjusting to fit this, to avoid relying on a ≤2.6σ event to explain it.
one would have to conclude that there are more (fainter) short GRBs than observed so far, and/or that there is another astrophysical population contributing to short GRBs, which was not yet fully recognized.

That might work if the culprit were a solar flare, but a GRB could come from anywhere in space.

If I read TFA correctly, then

a) the C-14 and Be-10 were formed in the atmosphere when/where the GRB hit, and
b) the tree-ring signal was present worldwide but more sharply focused in Japan than in America and Europe.

So Japan would have been in the direct line of sight and received the maximum concentration of radionuclides immediately, while Europe and America were not directly affected and would only have received whatever blew in on the wind over a period of time.

The article talks about the different ways GRB can occur. One forming from the creation of a black hole in our galaxy, and aimed towards us, would have devastating effects on just about everything. Plus it would result in a different ratio between radioactive carbon and beryllium. The kind that forms from two neutron stars colliding is apparently less energetic and not as deadly to life beneath the atmosphere.

They might want to mention God, too. Wait; is God an alien? I have to think about this, so nobody start adding this to their space articles yet. Ok?

Millennium: What I find interesting about this finding is that gamma-ray bursts have for some time been a classic life-ending disaster scenario: the sort of thing that causes massive extinctions and ends nearly all life on Earth (or, depending on who you ask, potentially all of it). This hypothesis, if true, would mean that we got smacked at essentially point-blank range by one, but nothing much happened. Either that was one weak ass-gamma burst, or they aren't actually the massive threat once believed.


This hypothesis estimates the distance of the GRB as between 3000 and 13,000 light years. Point-blank range would be closer to 100 light years, and at that distance it would probably do a lot of damage. But if it were far enough away it wouldn't have any direct impact on life. Of course, as the article also pointed out, if that were to happen today it would destroy our satellites and melt our power grids. So no mass extinctions but human civilization would be farked up.

ferretman: Is it possible to determine where the Earth was in relation to it's location in the solar system and be able to determine the direction this burst supposedly came from? Then they could scan that area and see if the could actually detect anything.


It would be very interesting to see if science can narrow it down to a more precise date range. According to TFA, the current estimate is about a two-year window. I'd think that in order to narrow it down to a section of space that could be closely and easily observed, that window would have to be about a week, perhaps two.

That's not to say it cannot happen, though. For example, I find it fascinating that geologists were able to trace the last mega earthquake along the Cascadia zone (Washington and Oregon) to about an 8-hour window on the evening of January 1, 1700, in part by using a combination of Native American and Japanese documentation of the earthquake and resultant tsunami. But, in this case, there were two big advantages: (1) That event was relatively recent, and many cultures were documenting their weather and geological events as they occurred; and (2) There was something directly observable (i.e., higher or lower land elevation, or increased tides many thousands of miles away).

People of the era when the GRB was supposed to have hit Earth were not nearly so sophisticated; they spent much of their time being afraid of the sun, so careful documentation probably wouldn't be in the cards. Plus, I'm not sure if there would even be anything observable, if what the author said is true (a two-second flash). Even if there was a culture back then that could rationally document such an event, some random circumstance (such as an overcast day) would easily FUBAR everything.

Happened 1200 years ago, but unlikely to happen again for hundreds of thousands of years.

Would you buy insurance from this person's company?

Lloyds of London sold Sputnik insurance, so anything's possible.

Good thing that the survivors will not have guns.

I don't know about that...

I wish a gamma-ray burst would've disabled that, as well. It's Bad Astronomy, not Teen Beat.

Ah, cut the guy a break. He was excited. It's not like he routinely abuses it.

Huh. It's not very scary if it didn't have any effects on humans.

Ficoce: Wait; is God an alien?


Well, he isn't "from" Earth (he may have created it, but, AFAIK he is no from "here"), and he is a "being", so, I'll go with "God is an Alien".

common sense is an oxymoron: So Japan would have been in the direct line of sight and received the maximum concentration of radionuclides immediately, while Europe and America were not directly affected and would only have received whatever blew in on the wind over a period of time.


Japan was the target then Ehh?
So not Early Medieval European Hulk. End of Yamato/beginning of Fujiwara period Godzilla then. Hmm..

It's probably just suggestive that his only editor is Office Spell Check. Actual humans used to proof and trim copy prior to publication, but electrons aren't seen as publication and Slate is probably run on the budget of the average bodega, so...

Yatima and the rest of Carter-Zimmerman polis will investigate this thoroughly, if they can convince the bridgers to help.

/every time I see GRB mentioned anywhere, that's the first thing that comes to mind
//who is thinking these thoughts? i am.

Lloyds of London will ensure ANYTHING. yes ANYTHING. Why? because like Ned Flanders they realize insurance is simply gambling.

hdhale: Still doesn't explain the stars and galaxies we can detect many, many millions of light years away.


Nah, they've already done that, including "God made the universe with the light IN TRANSIT", to "The speed of light was drastically different in the early days of the bible, just like people lived drastically longer!!"
