Physical Predilections often they manifest themselves in casual remarks like, ‘This violates causality and is, therefore, impossible’. Perhaps, a too thorough analysis of these principles would be redundant, but on the other hand, in discussing the subject matter of this book the traditional half-poetic approach is definitely insufficient.作者: 花爭吵 時(shí)間: 2025-3-22 22:41 作者: 出沒 時(shí)間: 2025-3-23 02:27
WEC-Related Quantum Restrictionsderation often violate the weak energy condition. Our task in this chapter is to explore the ensuing consequences and to check whether they prohibit exotic spaces as the lack of exotic matter prohibits such spaces in the classical case.作者: 倔強(qiáng)一點(diǎn) 時(shí)間: 2025-3-23 09:22

Frosso S. Makri,Zaharias M. Psillakisrespondingly, we start the book with a brief introduction to that discipline. In the first four sections of this chapter some basic notions—such as convexity, causal simplicity and global hyperbolicity—are defined and some basic facts about them are provided, such as Whitehead’s and Geroch’s theorem作者: 合唱隊(duì) 時(shí)間: 2025-3-24 11:49 作者: TAP 時(shí)間: 2025-3-24 17:22
