内部对比关系

Internal Relativity

Olaf Dreyer

摘要:

广义相对论与自然界中其他力的不同之处在于,它可以在局部消失。这就是等效原则的实质。在广义相对论中,等效原理是用微分几何来实现的。来自度量的连接被用来将不同的无引力闵可夫斯基空间粘合在一起。在这篇文章中,我们认为有另一种方法来实现等效原则。以这种新的方式,连接的不是不同的闵可夫斯基空间,而是一个潜在的固态模型的不同真空。这种引力方法的一个优点是,我们可以从量子力学模型开始,这样就不会出现如何得出引力的量子理论的问题。我们展示了如何在这个设置中计算引力常量。

英文摘要:

General relativity differs from other forces in nature in that it can be made to disappear locally. This is the essence of the equivalence principle. In general relativity the equivalence principle is implemented using differential geometry. The connection that comes from a metric is used to glue together the different gravity-free Minkowski spaces. In this article we argue that there is another way to implement the equivalence principle. In this new way it is not different Minkowski spaces that are connected but different vacua of an underlying solid-state like model. One advantage of this approach to gravity is that one can start with a quantum mechanical model so that the question of how to arrive at a quantum theory of gravity does not arise. We show how the gravitational constant can be calculated in this setup.
