Patiesā notikumu gaita - Zelta melnais caurums

From: markizs Date: 18. Marts 2005 - 11:44 (Link)

kādā rakā var sabrukt melnais caurums? kā var izmērīt melnā cauruma temperatūru. un atomi nevar pārvietoties ar gaismas ātrumu, jo tiem ir masa.

par ātrumu ir kaut kāds murgs tur, bet par sabrukšanu - visi melnie caurumu kaut kad izbeidzas

hmm. a kapēc jamie izbeidzas? ja jau jamie tikai ēd un ēd daļiņas un ārā nekādu enerģiju nedod un nevar izdodt principā.

doh, izdod gan! radiāciju dod kā negudri. un viņi paši sevī ar laiku sabrūk iekšā un izbedzas. vot

"A black hole is a concentration of mass with a gravitational field so strong that the escape velocity from nearby points exceeds the speed of light. This implies that nothing, not even light, can escape its gravity, hence the word "black." The term "black hole" is widespread, even though the theory does not refer to any hole in the usual sense, but rather a region of space from which nothing can return." un radiaacija nenaak no pasha melnaa cauruma, bet no notikumu horizonta robezhas.

nu ja ļoti piekasās, tad es ar varu akceptēt, ka no notikumu horizonta ;)))

bet vaig ar jaunāku lietartūru palasīt - viņi ar laiku izzūd!

nee nu es jau fizikjis neesmu. sen arii neko lasijis neesmu. a kamdeelj vinji izzuud? kur taa masa paliek ja jamaa seviski nav spejiga pamest to caumuru?

visa tai radiāciā pazūd. bet superstīgas to skaidro vēl sarežģītāk - tik sviestaini, ka baidos, ka nevarēšu atreferēt

hmm jaa taisniiba.
"Hawking radiation originates just outside the event horizon and, so far as it is understood, does not carry information from its interior. However, this means that black holes are not completely black: the effect implies that the mass of a black hole slowly evaporates with time. Although these effects are negligible for astronomical black holes, they are significant for hypothetical very small black holes where quantum-mechanical effects dominate. Indeed, small black holes are predicted to undergo runaway evaporation and eventually vanish in a burst of radiation. Hence, every black hole that cannot consume new mass has a finite life that is directly related to its mass."
