论文摘要
We present some historical and philosophical reflections on the paper "On the Relation Between the Expansion and the Mean Density of the Universe", published by Albert Einstein and Willem de Sitter in 1932. In this famous work, Einstein and de Sitter considered a relativistic model of the expanding universe with both the cosmological constant and the curvature of space set to zero.尽管Einstein-Desitter模型继续在“ Big Bang”宇宙学中充当标准模型多年,但我们注意到作者并未明确考虑论文中宇宙的演变。确实,文章的数学非常困惑。我们认为该论文既不是原始也不重要。我们发现,通过对动态宇宙学的第一个特定分析而没有宇宙恒定或空间曲率的情况,作者提供了一个独特的,简单的模型,具有宇宙扩展与物质平均密度之间的直接关系,为理论家和观察者提供了重要的基准。我们考虑了该模型的一些哲学方面,并简要回顾了它作为20世纪大部分时间的原型“大爆炸”模型的使用。
We present some historical and philosophical reflections on the paper "On the Relation Between the Expansion and the Mean Density of the Universe", published by Albert Einstein and Willem de Sitter in 1932. In this famous work, Einstein and de Sitter considered a relativistic model of the expanding universe with both the cosmological constant and the curvature of space set to zero. Although the Einstein-deSitter model went on to serve as a standard model in 'big bang' cosmology for many years, we note that the authors do not explicitly consider the evolution of the cosmos in the paper. Indeed, the mathematics of the article are quite puzzling to modern eyes. We consider claims that the paper was neither original nor important; we find that, by providing the first specific analysis of the case of a dynamic cosmology without a cosmological constant or spatial curvature, the authors delivered a unique, simple model with a straightforward relation between cosmic expansion and the mean density of matter that set an important benchmark for both theorists and observers. We consider some philosophical aspects of the model and provide a brief review of its use as a prototype 'big bang' model over much of the 20th century.
