Abstract

In this paper we consider the implications of a cosmological constant for the evolution of the universe, under a set of assumptions motivated by the holographic and horizon complementarity principles. We discuss the ``causal patch" description of spacetime required by this framework, and present some simple examples of cosmologies described this way. We argue that these assumptions inevitably lead to very deep paradoxes, which seem to require major revisions of our usual assumptions.

Discussions

• This problem was pointed out in 2002 by Dyson, Kleban, and Susskind; it was dubbed the "Boltzmann Brain" problem by Albrecht and Sorbo in 2004. (9/n) arxiv.org/abs/hep-th/0... arxiv.org/abs/hep-th/0.. [bsky, 32 points, 1 comments]
• permanece constante y entonces el teorema de recurrencia de Poincare es inevitable. Ahora, el tiempo de retorno es enorme (algo así como la exponencial de 10^{120}). [bsky, 1 points, 0 comments]
