论文摘要
根据Hot Big Bang模型和大统一理论，讨论了宇宙进化的早期阶段。大爆炸的缺点总结了，他们通过通货膨胀宇宙学的解决方案被勾勒出来。宇宙学通胀，随后的振荡和衰减的充气场以及由此产生的宇宙重新加热。引入了通过通货膨胀产生的密度扰动和宇宙微波背景辐射的温度波动。分析了通过非热静脉生成的男性生成，并提出了宇宙中的暗能量和物质。量子重力和弦理论非常简短。根据弦理论讨论了通货膨胀的初始条件问题，并提到了通货膨胀可能可检测到的原始重力波。
The early stages of the universe evolution are discussed according to the hot big bang model and the grand unified theories. The shortcomings of big bang are summarized and their resolution by inflationary cosmology is sketched. Cosmological inflation, the subsequent oscillation and decay of the inflaton field, and the resulting reheating of the universe are studied in some detail. The density perturbations produced by inflation and the temperature fluctuations of the cosmic microwave background radiation are introduced. Baryogenesis via non-thermal leptogenesis is analyzed and dark energy and matter in the universe are presented. Quantum gravity and string theory are very briefly introduced. The problem of initial conditions for inflation is discussed in the light of string theory and the possibly detectable primordial gravity waves from inflation are mentioned.
