"The really cool thing about this GRB (gamma-ray burst) is that because the exploding matter was traveling at [nearly] the speed of light, we were able to observe relativistic shocks," study co-author Giacomo Vianello, a postdoctoral scholar at Stanford University in California, said in a statement. "We cannot make a relativistic shock in the lab, so we really don't know what happens in it, and this is one of the main unknown assumptions in the model. These observations challenge the models and can lead us to a better understanding of physics."

No explosion defied anything.
I'm getting sick and tired of this shit.
However, on a more positive note, when even science-based websites are overselling news reports using the same blather template they use to sell Kim Kardashian's latest baby bump, it would seem that the race to the bottom is just about over.
Shorter version: "We do not know what the hell happened, but something went boom/flash, then disappeared into blackness. We put a pic of it on pinterest."
"And we aren't alluding to Nancy Sinatra's career."
Likewise, if you want to detect gravity waves with a series of satellites, call it a gravity wave observatory rather than a gravity wave detector.
Funds are easier to get.
Not that it isn't interesting but spin is spin.
That they have models in the PR is not a good sign.
That was, in fact, one of Hillary's farts.
She and the lesbos were playing with matches.
Are you sure it wasn't the Democrats using the nuclear option?
The previous gamma ray shocks scientists here.
I think there's one about to blow that's possibly aimed at us in the Crab Nebula. If it goes, we go.
Which is what I was actually goodling for.
Ah, here it is.
Eta Carinae.
The gamma radiation is emitted in a narrow cone from each pole of the collapsing star. So even if Eta Carinae goes boom, chances that one of its poles is pointed right at us are pretty small.
Crab Nebula? Isn't that an entirely different galaxy than the Milky Way we're out on the edge of?
Good memory, Hardin. Hadn't thought of USS Clueless in quite some time. Still miss it though.
All the nebulas we know about are in our galaxy. Other galaxies used to be CALLED nebulas until we realized what they really were.
I realize that light years are distance measurements, but how long will it take 9000 ly to reach us?
Hmm, traveling at the speed of light, that should take about 17 trillion dollars, give or take.
Tell me about it.
If it happened 8,999 years ago, about a year.
So, by the time we see it, we have a year, if the cone is aimed at us?
No, when we see it, it's here. Visible light, like gamma rays, is a frequency of radiation. It all moves at the same speed.
At least it'll be quick. Thanks, Mumps :)
