		<description>OK, I can follow the reasoning behind the accretion disc constraining this material so it only comes out along an axis of symmetry but why doesn&#039;t it then fan out? A radiating point inside a cylinder would produce two roughly conical emissions surely? These are definitely constrained to cylinders but why? And what&#039;s with the extra lobes at the limits of the structure that start to appear at Oct 2006?</description>

		<description>Davis asked: &quot;How is it then possible that this star 25,000 light years away will blast light/matter at such a speed that it will reach earth in 1 minute. Am i missing something here?&quot;

Yes you are. Read again what the BA said: &quot;...it ejected a lot of matter...at very high speed, about 24 million kilometers per hour (14 million mph). That would reach from the Earth to the Moon in one minute flat.&quot;

So not from the supernova to the Earth in one minute, but at a speed which would allow it to travel the distance between the Earth and the Moon in one minute.</description>

		<description>@ Janis

Sorry, to destroy your hope, but a supernova does not rise or fade very quickly. In fact, they tend to shine for several weeks and fade very slowly. I read somewhere that this special supernova in this thread would be visible with the unaided eye for about 3 month.

So what else could it have been? A meteor, a satellite or the ISS (did you see some movement? But even if you detected none does not rule out these possibilities). It could even have an earthly cause.</description>

		<description>hmmm 25,000 light years away... lets see 186,000 miles per second times 60 seconds times 60 minutes times 24 hours times 365 days times 25,000 years... thats a tad more than a stones throw. Given the distance, its probably already happened and the light is still headed in our direction.</description>

		<description>Last night (November 19th at approx 1:45AM PT) I was still awake laying with my eyes closed in bed.  I have a good view of the stars from my cathedral windows - With my eyes closed, saw a bright flash of light and opened them to see a star (or something in space) flash big, then die down like a match, then gone...could this have been THIS supernova?  I cannot find any info anywhere on this event last night...

If this was not a supernova, anyone know what it was?</description>

		<description>Funny, it looks exactly like chromosomes being pulled apart during mitosis. 

It would be awesome to see a supernova with my own eyes, thanks for the info! You&#039;ve got another reader. :)</description>

Yeah, the biggest problem with that episode was how small the stargate was compared to the star.</description>

		<description>Let&#039;s remember the laws of time travel. At 25,000 LY away, we are seeing this as it was 25,000 years ago.  It may have already exploded and we will not know it until the light from the event reaches us.  So predictions seem pointless.</description>

		<description>All the explanation is appreciated.

But any analysis &amp; interpretation of the observation &amp; measurements is dependent on the model one applies to data.

Applying a different model to the same observations &amp; measurement will result in different conclusions.

Mention has been made of magneto-hydro-dynamics, in other words, the study of electrified plasma dynamics.

Electromagnetism in plasma flows is scale independent with no limit established (confirmation of scale-independence has been observed to at least 14 orders of magnitude).

The explanations provided thus far are primarily of the gravity &quot;only&quot; model with some reference to MHD.

But if one applies an electromagnetic model to the data, one can easily come to different conclusions.

Z – pinch phenomenon are well understood and documented in plasma physics laboratories:

http://www.plasma-universe.com/index.php/Pinch

If one applies that model of the phenomenon then one comes to a different conclusion from the primarily gravity &quot;only&quot; model&#039;s conclusions.

To refresh my question: How does a near to exploding star have the same shape as a star forming region (why the beginning and ending are similar) ? 

The answer is easy to explain: The processes governoring the processes are the same. The Z- pinch process constrains both how a star forms and how it ends. In the ending senario, the current is increased until the circuit overloads and explodes, i.e., exploding double layers.</description>

		<description>47. ND

Let&#039;s see. Since a stargate only allows matter to flow one way, I suppose we could connect one star with another, then open the Gate and watch the flow build up,,,,oh, wait, we don&#039;t have access to a Gate big enough for starships to pass,,,oh well, never mind.(Ok! So! There would be matter flow, but it would take about a billion years to get enough mass accumulation to trigger a nova).

A better way might be to use a super particle accelerator to accelerate protons into a target and produce muons, to catalyze the stars nuc reactions. Could maybe increase the reaction rate to a bigga boom.

		<description>What if we could capture the energy produced when that thing explodes. Imagine that. We would have the energy that the sun would produce in over 1000 years! Talk about being efficient. Not only would we have to stop depending on other countries for our energy. AND we could find a way to sell this energy and our economy would boom. Think about it :)</description>

&quot;@ ND:
grrr. I can’t wait that long! I want a Type Ia and I want it now!
That can be arranged. Buwah ha ha ha haaaa!&quot;

You have a stargate lying around?

Testing to see if blowing up a star using a stargate sounds like a great Mythbusters episode!</description>

Ref your link: &quot;There is a constrant stream of high-energy galactic and solar radiation interacting with the Earth’s upper atmosphere,&quot; the report noted. &quot;This interaction creates a cascade of secondary particles. Some of the secondary particles, in particular neutrons, can affect aircraft avionics systems.&quot;

I guess that means the electronics they use aren&#039;t radiation hardened. I note they imply neutrons are secondary radiation, but from what I recall of my basic physics, energetic interactions  between cosmic rays and the atmosphere should mainly produce charged particle secondaries, not neutrons.
Ah well, I guess we can&#039;t expect all avionics experts to also be grounded in physics.

This is sad. Such a glorious piece of astronomy and science, and I think of the EU-crap. Sorry, guys.&lt;/blockquote&gt;

<blockquote><p>Some of those frakkin’ EU-guys showed this star as evidence for a current powering a star. I guessed that it would be outflows and that something is blocking our view in the middle. But that it is a possible Type Ia-candidate would have been much more interesting and much more compelling.</p>
<p>This is sad. Such a glorious piece of astronomy and science, and I think of the EU-crap. Sorry, guys.</p></blockquote>
<p>Hey, what&#8217;s your beef with the European Union anyway?</p>

&lt;i&gt;Here is a chalenge for the LHC Super Collider, cCreate a Supernova. A small one please. &lt;/i&gt;

I don&#039;t think supernovae come in &quot;small&quot; -  &amp; I think you need a star before you can have a supernova too. 

So I somehow doubt that the LHC will be able to grant that particular request there! ;-)</description>

		<description>1. Question. -the speed of light is constant. -Nothing can travel faster than the speed of light - 

How is it then possible that this star 25,000 light years away will blast light/matter at such a speed that it will reach earth in 1 minute.

Am i missing something here?</description>
