真空对宇宙拉伸的响应：加速宇宙与奇点规避
斑图形成与孤子

摘要
时空拉伸与时空曲率一起被纳入广义相对论。真空对宇宙拉伸的响应被视为宏观量子效应。这种效应解释了宇宙的加速膨胀，而无需诉诸普朗克尺度。对于负拉伸（坍缩），同样的效应可以阻止奇点的形成。拉伸效应可能对各种宇宙现象都很重要，包括星系碰撞和局部坍缩。

备注
Gravitational collapse and prevention of singularity is considered additionally to the problem of accelerated expansion of Universe (with the same modification of the general relativity as in the previous version of the paper). Correction is made for the epoch of ultrarelativistic equation of state. 7 pages
