用熵取代人类学:它有效吗?

Replacing Anthropy with entropy: Does it work?

Irit Maor, Thomas W. Kephart, Lawrence M. Krauss, Y. Jack Ng, Glenn D. Starkman

摘要:

可能不会,因为有很多明显非人类的方式产生熵。我们证明了因果熵原理(CEP),作为人择原理的替代品来解释观测宇宙的性质,遭受许多相同的问题,采用近视假设,以预测各种基本参数采取近似观测值。特别是,我们证明了四种机制--黑洞产生、黑洞衰变、相变和暗物质湮灭或衰变--将明显改变CEP的结论,以预测我们应该生活在一个与我们所处的宇宙截然不同的宇宙中。

英文摘要:

Probably not, because there are lots of manifestly unanthropic ways of producing entropy. We demonstrate that the Causal Entropic Principle (CEP), as a replacement for the anthropic principle to explain the properties of the observed universe, suffers from many of the same problems of adopting myopic assumptions in order to predict that various fundamental parameters take approximately the observed values. In particular, we demonstrate that four mechanisms -- black hole production, black hole decay, phase transitions, and dark matter annihilations or decays -- will manifestly change the conclusions of the CEP to predict that we should live in a universe quite different than the one in which we find ourselves.
