Filippenko and Jay M. Pasachoff〕〔(【引用サイトリンク】title=A Universe From Nothing lecture by Lawrence Krauss at AAI )〕 ==History== Pascual Jordan first suggested that since the positive energy of a star’s mass and the negative energy of its gravitational field together may have zero total energy, conservation of energy would not prevent a star being created by a quantum transition of the vacuum. George Gamow recounted putting this idea to Albert Einstein: “Einstein stopped in his tracks and, since we were crossing a street, several cars had to stop to avoid running us down”.〔(Beyond Einstein: The Cosmic Quest for the Theory of the Universe - Michio Kaku, Jennifer Trainer Thompson - Oxford University Press, 1997 - p189 )〕 The zero-energy universe theory originated in 1973, when Edward Tryon proposed in the ''Nature'' journal that the universe emerged from a large-scale quantum fluctuation of vacuum energy, resulting in its positive mass-energy being exactly balanced by its negative gravitational potential energy.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Zero-energy universe」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
