Talk:Kugelblitz (astrophysics)

untitled
The article says: "The best known temperature for a Kugelblitz to form is 141 billion billion billion Kelvin". I've done plenty of work on general relativity, this makes no sense to me: a sufficient quantity of electromagnetic radiation can form a black hole regardless of the temperature. Since no citation is provided, I'm going to delete this. If someone can explain it, we can restore it. John Baez (talk) 03:15, 3 February 2013 (UTC)

 * Actually, it was most probably a reference to the Planck temperature. --Florian Blaschke (talk) 14:42, 9 January 2014 (UTC)

This idea deals with both elementary particles and gravitation. Would not a theory of quantum gravity be needed for a structure of this type to form?67.233.161.244 (talk) 03:36, 2 July 2016 (UTC)

Popcultural references...
Oh, now there's a thing. Might have to go bother Sarah Sugar on twitter or something to see if her Gem ships are essentially using this technology for interstellar travel; there seems to be a huge amount of hard photonic sci-fi hidden in layers behind the surface story of Steven Universe and this could well be another example of such (e.g. the Gems themselves seem to essentially be semi-natural, semi-artifical intelligences occupying crystalline photonic-circuit computer devices melding processor, memory, networking hardware, sensors, some kind of environmental energy sponge and a holographic gemstone-type laser projector with enough power to form a hard-light body and some quite destructive energy weapons from captive photons... and there's all kinds of other seeming nods to closely related scientific concepts and techniques, too many to list, which give me pause for thought every time I read something in an scientific article and realise it seems familiar from the cartoon... as well as some more mundane geological, gemological (sounds dumb but that's the real term) or biological science that still isn't shown front-and-centre but seems to sit very obviously behind what's animated if you happen to know anything about the subject already).

The relevant part being how they appear to use a type of warp drive employing a spontaneously generated and steered miniature black hole (which appears black rather than emissive of Hawking radiation, maybe just to make it clear what it's supposed to be, as well as having a fairly considerable Schwartzchild radius that would suggest an effective mass on the order of Jupiter, though that's probably exaggerated for visual effect as well given that it doesn't immediately destroy everything in sight) that is ejected out of the front of the ship and then very rapidly drags it forwards whilst itself shooting forwards at extreme speed (clearly supraluminal after less than a minute of acceleration at no more than maybe 10G as perceived on-board, and enough to cause severe visual and (four-)dimensional distortion, ie size, hue shift/wideband chromatic abberation, and time, with photonic projections having extreme difficulty matching pace with that of the matter from which they're produced) suggesting classicaly theorised spacetime-warping...

...but how do you spontaneously produce something like that from a small craft which otherwise doesn't seem to weigh more than a few tonnes and doesn't have any obvious power source other than the "usual" Gem-stuff? Answer: Kugelblitz. It's essentially nothing more than an extremely powerful, extremely tightly focussed holographic projection, almost another type of weapon. Instead of shooting it at an adversary as a series of discrete bolts in order to bring about their destruction, just concentrate all that energy towards a single point in space a few metres ahead of the craft. Given how dense a photon field you'd need to exert any kind of measurable physical force, let alone weapon effects other than burning, it probably wouldn't even be too difficult, especially with a drive matrix that could be thousands of times larger than a normal personality-core gem (each about the size of a macaron biscuit) still without being particularly massive and entirely devoted to producing the KB beam... and the Big Bads in the show have already demonstrated that they can deliberately inflict a planetary-scale attack analogous to the EMP - or EPP? (but thankfully not the biological sterilisation, despite it scrambling photon circuits) - of a Gamma-Ray Burst as a Kill 'Em All desperation tactic... not to mention the Lion/etc wormholes, subspace warp pads, and so-on, so that kind of energy manipulation and containment on a literally stellar scale, to the point of being able to make black holes from light alone, wouldn't be at all out of tune with everything else.

(file under Massively Over-Analysing The Source Material ... however, the idea to go ask the creator/lead writer about it is an acknowledgment that it's nothing but conjecture at this point, and it wouldn't be suitable for unilaterally adding to the article without having done so) 209.93.141.17 (talk) 23:45, 11 September 2017 (UTC)


 * What exactly is your suggestion to improve the article? That's what talk pages are about. --mfb (talk) 12:14, 12 September 2017 (UTC)

Not sure it belongs in the article since there's no pop cultural reference section, but FWIW, it appears this concept features in The Umbrella Academy (TV series) (it is mentioned in the trailer and seems to be shown) - and is also the episode title, S3E4. 207.181.234.72 (talk) 01:50, 19 June 2022 (UTC)

Comment The "Kugelblitz" referenced in the show was not actually a Kugelblitz in terms of the described Physics. There is a reveal at the end of the season that shows "Five" had an incorrect assumption of the Physics of the object. Before you edit Pop Culture references into an article, be sure to actually consume the media. -- Sleyece (talk) 22:17, 10 July 2022 (UTC)

"heat, light or radiation"
The article says that a kugelblitz is a concentration of "heat, light or radiation." By "heat," does it simply mean infra-red light?

Also radiation could be particulate matter. Would that still be a kugelblitz?

Should it just say "electromagnetic radiation" instead? — Preceding unsigned comment added by 93.191.200.74 (talk) 20:38, 9 July 2019 (UTC)
 * Anything with energy where mass isn't dominant. "formed from radiation" is used later in the article. --mfb (talk) 03:35, 10 July 2019 (UTC)

Kugelblitz...
...in my language (German), this does not (commonly) refer to black holes. The correct term and page is Geon (astro physics), which also exists in the English Wikipedia.

So remove the german pronunciation reference, maybe merge pages Geon.

Kugelblitz refers to a round kind of lightning, as the world literally means that. Feuerswut (talk) 18:20, 16 June 2024 (UTC)
