Frosso S. Makri,Zaharias M. Psillakis simple sets—appear and the theorem is proved which states that they exist in arbitrary spacetime. We shall use this theorem in proving Theorem . in Chap. 5, but, as it seems, it is interesting also by itself (the perfectly simple sets are ‘as nice as possible’—they are both convex . globally hyperb

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.

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.
