Diverses
Zum letzten Satz, Folge "Das kosmische Band" von Star Trek, Next Generation: Ist das ein kosmischer String ? Soweit ich mich erinnere, war das Phänomen zweidimensional, der Artikel beschreibt kosmische Strings aber als (fast) eindimensional. Andererseits: Wieso sollten die hier beschriebenen kosmischen Strings eigentlich eindimensional sein ? Das wäre erklärungswürdig.
Zur "Kristallisation" (2. Absatz): Den Begriff kannte ich auch schon, aber der Link ist leider falsch, weil dort die Bildung von Kristallen beschrieben wird. Ich habe leider keine Ahnung, wie ich das sinnig kennzeichnen sollte - den Link zu löschen, fände ich jedenfalls auch nicht gut.

Unlogik
Der Satz beim Stand vom 15. Juni 2006
"Kosmische Strings könnten in der kurzen Zeit nach dem Urknall entstehen, als sich die GUT durch Abkühlung und Symmetriebrechung in die elektroschwache Wechselwirkung und die starke Wechselwirkung aufgespalten hat." ist in sich logisch, jedoch war anscheinend das Ding "GUT" (soll "Große Vereinheitlichte Theorie" bedeuten) hier falsch und wurde einfach ersatzlos rausgeworfen.
jetzt ist der Satz in sich unlogisch mit
"Kosmische Strings könnten in der kurzen Zeit nach dem Urknall entstehen, als sie (!) sich durch Abkühlung und Symmetriebrechung in die elektroschwache Wechselwirkung und die starke Wechselwirkung aufgespalten hat."
Auch die grammatische Zeitform geht hier durcheinander mit "... könnten in der kurzen Zeit nach dem Urknall - (also vor 15 Milliarden Jahren oder so) - entstehen - (=heute??) - ...."
Trau mich aber hier nicht einzugreifen. --84.143.58.44 09:43, 18. Mär. 2007 (CET)
Kandidat für einen beobachteten kosmischen String - Erwähnenswert?

Quantumfaden?
Guten Morgen. Also dieser hier (nebenan, auf der Vorderseite gegenwärtig) – bisher auch nur hypothetisch (oder übersetzt „unterstellt“ also letztlich nur [wenn auch rechnerisch nachweisbar] ausgedacht) – beschriebene kosmische String könnte womöglich das Selbe sein wie der sogenannte Quantumfaden in wenigstens einer der Sternenreise-Folgen (siehe auch unter Memory-Alpha[…]Quantumfaden). Ist nur mal so ein (durchaus ernstgemeinter) Gedanke, ganz im Sinne des hier immerhin auch angestrebten freien Wissens sowie auch (wörtlich) im Sinne der Wissenschaft und um ggf. mal einen Denkanstoß zu geben. Zudem wird ja (meines Wissens nach) gegenwärtig auch noch immer (wenigstens teilweise) so getan, als seien die sogenannte Quantenfeld- und Stringtheorie was ganz Verschiedenes oder (bisher) nicht vereinbar, obwohl beide womöglich auch nur das Selbe jedoch nur aus anderen Blickrichtungen (bisher nur versuchen) zu beschreiben, ähnlich wie anfangs bei der Beschreibung des Lichts (siehe auch Welle-Teilchen-Dualismus und die bisher noch immer nur unzureichend verstandene Schwerkraft oder auch das Schwerefeld, welche auch einerseits als [Kraft-]Feld und andererseite als irgend eine Art von Raum-[Zeit-]Krümmung verstanden werden kann [oder womöglich tatsächlich zu verstehen ist]). Mit lieben Grüßen. -- 77.11.57.87 05:24, 3. Feb. 2021 (CET)
Planck-Satellit
Der Planck-Satellit wurde bereits 2013 abgeschaltet und hat wohl keine Hinweise auf kosmische Strings gefunden, jedenfalls ist er nicht mehr "zukünftig". 2003:CA:E72E:600:5CCF:8349:E6DD:7195 07:53, 18. Feb. 2022 (CET)
