Kugelblitz (astrophysics): Difference between revisions

A <!--Schwarzschild -->'''kugelblitz''' ({{IPA-|de|ˈkuːɡl̩ˌblɪt͡s|lang|De-Kugelblitz.ogg}}) is a [[theoretical physics|theoretical]] astrophysical object predicted by [[general relativity]]. It is a concentration of [[heat]], [[light]] or [[radiation]] so intense that its energy forms an [[event horizon]] and becomes self-trapped. In other words, if enough [[radiation]] is aimed into a region of space, the concentration of energy can warp [[spacetime]] so much that it creates a [[black hole]]. This would be a black hole whose original [[Mass–energy equivalence|mass–energy]] was in the form of [[radiant energy]] rather than matter,;<ref>{{citeCite journal |last=Senovilla |first=J.José M.

[[John Archibald Wheeler]]'s 1955 ''[[Physical Review]]'' paper entitled "[[Geon (physics)|Geons]]" refers to the kugelblitz phenomenon and explores the idea of creating such particles (or [[toy model]]s of particles) from [[spacetime]] curvature.<ref name = "Wheeler1955PhysRev">{{citeCite journal |last=Wheeler |first=J.John A.Archibald |authorlinkauthor-link=John Archibald Wheeler |yeardate=15 January 1955 |title=Geons |url=https://journals.aps.org/pr/abstract/10.1103/PhysRev.97.511 |journal=[[Physical Review]] |language=en |volume=97 |issue=2 |pages=511–536 |doi=10.1103/PhysRev.97.511 |bibcode = 1955PhRv...97..511W |volumeissn=97 |issue=2 |pages=511–5360031-899X}}</ref>
