Robotic Telescope Unravels Cosmic Blast Mystery
An anonymous reader writes "The Register is reporting that scientists from Liverpool John Moores University have used their robotic telescope in the Canary Islands to measure the polarization of light from a Gamma Ray Burst just 203 seconds after its detection by NASA's Swift Gamma Ray Observatory Satellite. The result suggests that the emitting material flowing out from the explosion may not be highly magnetized in the way that some theories had predicted."
It shouldn't surprise us that GRB's don't behave as we thought. Nearly everything we think we know about them is based upon assumptions and speculation that are only minimally supported by evidence. There is potential for error at every single step of this process. To continue to be surprised that our telescopes are returning anomalous data when that's what's been happening nearly every single day for years and years and years is silly. At some point, you have to go back to your assumptions and figure out where you went wrong.

In fact the whole idea is to sometimes find out surprising things that find flaws in the old models and give information to drive the creation of more accurate models. (One definition of information transfer is how much the receiver is surprised. B-) )
That's what we're spending all this money for: To come up with physics that more closely matches the real universe. To do this we have to know what's NOT matching in the old models.
(For those - ideally few of the slashdot participants - who gripe that it's being spent at all: At some point the improved models will almost certainly produce some new and useful technologies and/or end squandering of resources on the pursuit of dead-ends. Of course you can't know up front WHAT technologies it will affect. That's part of what you're finding out.;)

I just thought I'd remind you that the original story is about some actual science carried out by real researchers, not a proposed plot for an episode of Star Trek.
Doesn't it make you feel good to know that our freedoms are protected by politicans, lawyers and journalists.
