引力物质：暗物质与宇宙学常数
Matters of Gravity: Dark Matter and the Cosmological Constant
摘要：
我们考虑了困扰物理学家几十年的两个问题--暗物质和宇宙学常数。问题是，前者尚未被检测到，而后者给出的值远远高于观察到的值。我们认为，一个随时间变化的引力常量避免了前一个问题，而后一个问题可以绕过考虑宇宙的平均密度。
英文摘要：
We consider two problems that have vexed physicists for several decades -- dark matter and the cosmological constant. The problem has been that the former has not been detected while the latter gives a far higher value than detected by observation. We argue that a time varying gravitational constant obviates the former problem, while the latter problem can be circumvented by considering the average density of the universe.
