论文摘要
我们展示了气泡动力学的雷利 - 植物方程的概括，包括表面张力，弹性和粘度效应与弗里德曼·莱玛特（Friedmann-Lemaître）方程的重新制作，这些方程描述了宇宙学中空间扩展的均匀和同性恋宇宙的扩展。通过比较流体和宇宙方程，我们提出了对新来的宇宙方程映射三个连续力学贡献的大胆概括。相反，在流体方程式中增加宇宙学常数项也将导致新的现象学。
We show the analogy between a generalization of the Rayleigh-Plesset equation of bubble dynamics including surface tension, elasticity and viscosity effects with a reformulation of the Friedmann-Lemaître set of equations describing the expansion of space in cosmology assuming a homogeneous and isotropic universe. By comparing both fluid and cosmic equations, we propose a bold generalization of the newly-derived cosmic equation mapping three continuum mechanics contributions. Conversely, the addition of a cosmological constant-like term in the fluid equation would lead also to a new phenomenology.
