摘要

早期宇宙早期宇宙的膨胀受到广义相对论中能量条件的约束。这张封面图像说明了这些限制所允许的密度ρ和压力p的范围，这意味着哈勃球体的线性膨胀是唯一不违反这些限制的情况。请参阅Fulvio Melia的文章编号2300157了解更多详细信息。

Early Universe

The expansion of the early Universe is constrained by the energy conditions in general relativity. This cover image illustrates the range of density ρ and pressure p permitted by these restrictions, implying that a linear expansion of the Hubble sphere is the only scenario that does not violate them. See article number 2300157 by Fulvio Melia for more details.

期刊介绍： Annalen der Physik (AdP) is one of the world''s most renowned physics journals with an over 225 years'' tradition of excellence. Based on the fame of seminal papers by Einstein, Planck and many others, the journal is now tuned towards today''s most exciting findings including the annual Nobel Lectures. AdP comprises all areas of physics, with particular emphasis on important, significant and highly relevant results. Topics range from fundamental research to forefront applications including dynamic and interdisciplinary fields. The journal covers theory, simulation and experiment, e.g., but not exclusively, in condensed matter, quantum physics, photonics, materials physics, high energy, gravitation and astrophysics. It welcomes Rapid Research Letters, Original Papers, Review and Feature Articles.
