In this paper, we give a physical explanation to the accelerated expansion of the universe, alleviating the tension between the discrepancy of Hubble constant measurements. By the EulerCauchy stress principle, we identify a controversy on the lack of consideration of the surface forces contemplated in the study of the expansion of the universe. We distinguish a new general relativistic effect that modifies the spacetime fabric by means of the energy conservation equation. The resulting dynamical equations from the proposed hypothesis are contrasted to several testable astrophysical predictions. This paper also explains why we have not found any particle or fluid responsible for dark energy and clarifies the Cosmological Coincidence Problem. These explanations are achieved without assuming the existence of exotic matter of unphysical meaning or having to modify Einstein’s Field Equations.

表面张力：加速膨胀、重合问题和哈勃张力

在本文中，我们对宇宙的加速膨胀给出了物理解释，缓解了哈勃常数测量结果之间的矛盾。通过欧拉柯西应力原理，我们发现了一个争议，即在研究宇宙膨胀时没有考虑表面力。我们区分了一种新的广义相对论效应，它通过能量守恒方程改变了时空结构。从所提出的假设中得到的动力学方程与几个可测试的天体物理预测进行了对比。这篇论文还解释了为什么我们没有发现任何负责暗能量的粒子或流体，并澄清了宇宙学巧合问题。
