Well, nebulas almost always emit X-rays, so I would guess they're pretty damn hot.

Re: Capella story question
I'm reading on wikipedia about supernovas to figure something about this and just noted something interesting, it says that: '' there are two possible routes to their formation. A massive star may cease to generate fusion energy from fusing the nuclei of atoms in its core and collapses inward under the force of its own gravity, or a white dwarf star may accumulate material from a companion star until it reaches its Chandrasekhar limit and undergoes a thermonuclear explosion . In either case, the resulting supernova explosion expels much or all of the stellar material with great force.''

Now this part is especially interesting:
''a white dwarf star may accumulate material from a companion star until it reaches its Chandrasekhar limit and undergoes a thermonuclear explosion''.

This maybe what the shivans did to Capella, but I didnt find any informationg to see if the Capella star is a white dwarf. Nevertheless I think its one most possible explanations to the whole thing.

Re: Capella story question
IIRC Capella is actually a system of four stars, two yellow giants and two red dwarfs.

I read the wikipedia description yesterday too. It says the material is blown off at up to 10000km/s, from which we may be able to get a very rough estimate of the nebula density if we know the star's mass. Although the stars in FS2 seem to have no resemblance to the real ones so it's hard to determine that.

Re: Capella story question
Well, the star that the shivans target is a yellow giant. On stellar classification it says that the mass of a star with the yellow color is 1.1 but I've got no idea as to what that means. :confused: But it says that the real Capella is on class G along with our Sun.

 
Re: Capella story question
1.1 refers to how massive it is in comparision to our Sun. The Sun has a mass of 1.0.

The Supermassive-Star-Dying method is called a Type-II supernova, while the White-Dwarf-Accumulating-Gas method is the Type-I.  They can determine the type based on the rate at which the explosion loses luminosity over time afterwards.  Also, a special note about the Type-I, the explosion results in the complete destruction of the white dwarf star, while the Type-II results in a neutron star being created (typically).

Re: Capella story question
The final cutscene shows us that the Deimos and Moloch have the ability to survive the initial blast wave from a super-nova

That wasn't a blast wave that was a heat wave. There's a signifcant difference.

Same thing basically. Same effect neways.

They would have probably waited for the ones already in subspace though, considering Petrarch's comment that "command is committed to getting every last Terran out of the system" (I won't get into why he didn't include Vasudans though, probably used to work for the NTF or something :p).

No vasudan civilians in the system most likely.

IIRC, there was vasudans, but the majority was Terrans. Mostlikely so little, as they would not need to mention the vasudan population in that system.

I just re watched the DiveDiveDive vid (google>vid>freespace). I always wondered, what if a ship jumped into a node from both ends. What would happen?

One answer may be 'yo will see them comeing twards you and go past you, if your in a subspace tunnel' ya know. In our subspace mission, imagine ships like that, but also going opposite ways. But i doubt that, as there woudl be subspace battels all the time, or Mjolre beams placeed inside subspace on a constant warp to destroy enemy contacts early. Meh ignore last comment.
The other would either be, the ships would collide and explode, or be defected\mutated. Or you just would pass through and not see the ship. It would happen unknowingly.

What do you think?

Re: Capella story question
Apparently they wouldn't go into the same tunnel without doing something special, considering that tracking the Shivans into subspace was such a big deal in FS1.

Re: Capella story question
I'd imagine that's it's something as simple as when two ships pass each other in any direction at warp speed in star trek. Or something like how ships share ftl jump codes and coordinates together in bsg.
Another thing, i think it's safe to say that ships share the same jump tunnel period, and that was not a part of being able to track ships into subspace. Otherwise how would alpha one and his buddies be able to catch up to the lucifer in the node to sol in fs1? Being able to track ships in subspace from outside of subspace is a big deal in fs1, and a different matter at that.

I doubt it. Capella has no white dwarfs and the red dwarfs orbit 11,000 AUs (1 AU = 92 million miles) from Capella's two yellow stars. If one of them had gone supernova you'd only have noticed 63 days later.

Besides :v: obviously didn't have good knowledge of astronomy as they refer to the Capella Star even though there are four stars in the Capella system.

On top of that if you watch the cutscene it's pretty obvious that it's the main star the Shivans are surrounding which explodes.

Finally even if we ignore all that I don't see any good reason why this is a better explaination than any other. If the Shivans had the technology to make a type I supernova they probably have the technology to make a type 2.

Well, the star that the shivans target is a yellow giant. On stellar classification it says that the mass of a star with the yellow color is 1.1 but I've got no idea as to what that means. :confused: But it says that the real Capella is on class G along with our Sun.

Both Capella A and Capella B are more than 2.5 times the mass of Sol. More data here and here

hi,
i thinks to place mjolre is first a bad idea, if they destroy ships inside the node and second: i think the subspace have many dimensions.
before the alliance find the ancient device it´s was impossible to local the right dimensions in where a ship travel through the subspace.
now you can check if there first a ship and if yes which dimensions its use.
so you can first tracking a ship in the subspace and second you can take another dimension so that you doesnt collided in the subspace.

thats my minds over this.

Re: Capella story question
Quite simply put to charismatics quote there, is that there is subspace battles all the time. Battle with the lucifer was one of them. After that, gtva usually doesn't fight in subspace tunnels very often, but i'd imagine that it happens for a ton of other people in the galaxy like pirates versus the transport.

Re: Capella story question
hi,
mhh i think maybe the problem is, that each fight do destabiles the subspace tunnel itself.
every weapon they fire, every ship that destroyed and maybe every use of subspace itsself.

maybe so the GTVA and any other normal person doesnt fight in subspace tunnels, then a node that to instable to travel and cutting of a star system.

but its possible that pirates or fanaticer attack in subspace, they doesnt bother if the whole tunnel blowing up.
but maybe theres another question, will fight the shivan in subspace normaly or only if this really neccesary, like the attack on the lucifer?

Re: Capella story question
Uh i only understood half of what Mehrpack said. Il move on.

Well what do you think is more likely. Several subspace dimentions\tunnels per node, so they dont see eachother of they both jump on opposite sides of a node. Or wil they see eachother or colide?

That's actually a very good question.  I believe that ships that enter a node, but are not "in sync" with each other, would not see each other or be close to each other in subspace.  If they were, then why would there be such a big deal in FS1 about being able to "track ships into and inside subspace"?  That would also explain how Alpha 1 and the attacking fleet was able to get close to the Lucifer at the end of FS1, even though they entered the node several minutes after the Lucy did.

Also, I believe someone asked how fast the shockwave from a supernova travels, and the answer is that at first, the expansion rate can be up to several percent of the speed of light, varying depending on the star.  The shockwave will slow down eventually as it spreads through the interstellar medium, and give off a fair amount of high-energy radiation in the process as well.  The real killer, however, is the enormous amount of gamma and X-ray radiation that travels out at the speed of light once the supernova begins.  That radiation is lethal to anything for a good hundred light years or so, depending on how energetic the supernova is.  Mmm, crispy fried.  (Not really... more like having your DNA torn apart, which would be just as bad).

Ooh, a cool picture of supernova 1987A to finish off this post.

Notice the bright, central ring.  That's the supernova shockwave plowing into material that was previously ejected by the star. (Circular shockwaves FTW) :D

Re: Capella story question
Subspace is n-dimensional; the problem goes deeper then being merely in sync, but to the point of ships using the same node not necessarily being in the same subspatial dimension.

Nevertheless it says somewhere in FS1 that the PVN and GTA had already fought inside subspace nodes and that the consequences were horrible enough that both sides never did this again.

hi,
i doesnt can remember that in FS2 somewhere that anybody say, and if yes, why then need the GTA and the PVN the ancident device to tracking the subspace activity if they can fight in subspace??

thats seems not logical.
