UA Mystery Thread 3: The Canonn

[PsychoFish]

Ok, sharper blue for Nicholas, bordered morse for Sigon, plus orange UA and colour on the bumpers for me. Any other changes?

Amazing. I want to switch paintjobs NOW.

Been doing a bit of doodling on ship design.......just an idea.

Wow .. I like this one too. Not the yellow, but the writing is amazing.

The UA logo in the centre, the wrinting on the sides and nice fitting colours and we could have a real contestant.

 

[Han_Zen]

In my book you'd be quite correct, as I don't think there's such a thing as an infinite density and therefore a singularity.
But that's a matter of personal opinion and ongoing debate, and therefore unlikely to actually contribute to solving the riddle of the UA.

What we know is that is much smaller than the event horizon in most cases.

A Black hole that is just a tiny bit abowe the maximum mass for a neutron star, could possibly allmost 'fill' the volume of the event hoizon.

We simply don't know.

 

[CMDR Runcible Shaw]

The density of a black hole can be two things.

Either it's infinite, as the BH can be viewed as a singularity or it's calcuated as mass divided by the volume of a ball with a radius equal to the Schwarzschild-radius of the mass.
This ball is sort of the theorethical event horizon.

In case of the latter method, small Black holes are very dense. Super massive BHs, not that dense.

I have no idea if this is relevant

Good point density goes as mass over volume, where volume goes as the schwarzschild radius cubed, so density goes as 1 over mass squared. Pretty neat.

Elegantly put and quite correct.

Who cares if it's relevant - it's real science

Oh and Runcible, I thought the Chandrasekhar limit, from memories of reading pop sci book by Brian Cox and Jeff Forshaw was 2.1M. But it's not, apparently it's 1.39M. But I didn't study it *ever* - so hats off to you anyway

....not even *two* maltesers. Imagine that!

 

[CMDR Runcible Shaw]

I think I know the answer to this, but signal sources never appear outside a certain distance from populated systems, right? Do we know that distance exactly?

 

[John Stoutbeard]

pfft even in 3301 there are teleevangelists who just want your money. unbelieveable!

probably nothing to do with UA, but as I was flying back to human space to carry out some repairs, I encountered this SSS, which is a new one to me. An orca and it was talking about family an how they look after each other and how if I paid them money I would have all my sins forgiven.

- Is this another (new) merchant?
- Or is it another 'assasin target' for assisin missions?

If it's a merchant, which creates his own SSS, he/her buys bodies?
If the UA is a lifeboat w/beacon - oh dear god, I have to say it ... "is he willing to buy it?" ... aaargh, why did I have to say that.

I actually really like both of these a lot. I like the yellow, personally - kind of looks official - like if you saw one of those in a warzone you'd avoid shooting it because you'd know they were doing important works(tm).

So I guess this is what's happening with VOyager..



Also the UA is mentioned briefly.

Yes, the 1000ly display-range change was a pure mechanical change back then. With unforseen consequences for looking the Voyager.
They are obvisouly rectifying it before they introduce more stuff into the void, so we can actually find it out there.
Good thing.

Hmmm... I've definitely not seen one outside 1000ly, bit O think I got one at about 750ly - popped up just on the edge of my FOV as I was rattling along in SC, but I spotted it too late to turn around and get it.

An official or hard-and-fast number though? Don't believe so.

Oof, I was wrong again. You're right, 1.39 is the Chandrasekhar limit, which is the limiting mass for a stable white dwarf. This has to do with electron degeneracy pressure, not neutron degeneracy pressure as I incorrectly edited my original post. Apparently the limiting mass for a neutron star is call the Tolman-Oppenheimer-Volkoff limit which I never learned in Stellar and had to look up on the Wikipedia. That's where I got 3 solar masses from somehow, which corresponds to something like 10 times solar mass when the star is on the main sequence. Whew!

What were we talking about? Whales?

Okay, I thought I read something in this very thread about it being a 200ly bubble from populated space. I'm getting bored sitting at HR 1185, so I think dump all my shields and such and go explore out to California and Back.

You lot do realise that a couple of pages ago someone offered to give away a ua?

Now all numbers are correct. We have proven that we can do real sience.

As you say, back to whales.

Biscuit anyone?

 

[Dr Black]

wouldnt it be sad if, at the end of all this, they turned out to be Nav Beacons? Sure- alien nav beacons, but basically the exact same thing we have close to all of our stars (that beep the system name in morse code as well).

I wonder if somewhere out there They are buzzing around a Nav Beacon of ours- scooping it up, trying this, trying that- closely examining the various doodads around its equator... applying old alien world technologies and folklore to it... trying to glean some "deeper meaning".

but who knows? nerdgasming out may be a common galactic phenomenon- regardless of the species.

Not sad, fantastic. Hopefully they are not some sort of Chinese puzzle, to knock and poke, but exactly what you would expect to find in space if you knew an alien species was around. A probe or diplomatic approach or some other thing that we would produce. Think simple!

I know how you feel......I've been asking for someone to try to just find a non degrading UA and then asked if someone is working on it.....

I guess after 3M they become singularities then?

Who cares about the whales, unless they're Egyptian or come bearing biscuits!

{OT:On} I learned about that limit from a book by Cox and Forshaw, all to do with QED and working out the probabilities of the future location of electrons by seeing them as clouds. They introduce the limit early on and tell you that you'll work it out by the end of the book. The journey there is quite simply amazing, and they point out just how old that prediction is, that it's still not been disproven, and how a bit of science on paper can predict such gargantuan realities. Love it.

I don't think FD read that book though. Newton yes; Dirac, Feynman et al, no. ED isn't real science, it's 'weird science'. {OT:Off}

That really is the last I'll say about that. Out of my depth really, anyway. Frequently

Yes.

I think Wishblend deserves it. She it a great tester and documentor.-

 

[PsychoFish]

I will try to find one in a system around the Pleiades where it hasn't been seen before. I have 2-3 hours. I will do the analasys of the planets in HR 1185 and HR 1172 tomorrow morning. Then I have to go on vacation ... you think I can find a UA in London?

Argh, I just missed a SSS .. I bet there was a UA in it ...

 

[LordZoltan]

Hi, I have a UA in my hold rotting my ship and my brain. I'm quite tired of this three-month riddle, with the ever-present possibility that it is all for (nearly) nought.

So, without further ado I offer to loan out my UA to anyone with a good name (joke) and a good research proposal (no joke).

PM me for details.

Sorry, yes - quoting here to bump it forward a bit.

Yes.

Great choice

 

[Dr Black]

Has anybody in the FD team described what the purpose of Nav Beacons really is? Apart from being a very bad spot to bounty hunt, does it help you discover celestial bodies inside the system? Planets that would not appear and require a Disco Scanner to spot?

Sorry if that's a really newbie question, but I haven't read any clear message from FD describing what they really do. They emit morse, just like the UA, they have a similar behaviour.

Can the next guy that discovers a freefloating UA NOT scoop it up and wait patiently for something to drop?

I thought they were old technology that you needed before the new FD drives come around and in fact are now of little or no use
