摘要：

我们详细阐述了假粒子的概念，并研究了它的物理后果。当一个理论包含伪量子时，真正的经典极限由量子化和随后的“经典化”过程决定。假粒子的主要预测之一是违反微观因果关系，它超越了经典极限。这一事实给实验检测违规带来了希望。自旋为2的伪子与标量场一起，能够使量子引力在保持么正性的同时可重整化。我们认为，从这种结构中产生的量子引力理论是正确的。通过经典化的方法，对广义相对论的场方程进行了修正。我们表明，最终的方程，在简单的条款，形式$\langle F\rangle =ma$，其中$\langle F\rangle $是一个平均值，包括一点点的“未来”。

英文摘要：

We elaborate on the idea of fake particle and study its physical consequences. When a theory contains fakeons, the true classical limit is determined by the quantization and a subsequent process of "classicization". One of the major predictions due to the fake particles is the violation of microcausality, which survives the classical limit. This fact gives hope to detect the violation experimentally. A fakeon of spin 2, together with a scalar field, is able to make quantum gravity renormalizable while preserving unitarity. We claim that the theory of quantum gravity emerging from this construction is the right one. By means of the classicization, we work out the corrections to the field equations of general relativity. We show that the finalized equations have, in simple terms, the form $\langle F\rangle =ma$, where $\langle F\rangle $ is an average that includes a little bit of "future".
