In this letter, the Friedmann–Robertson–Walker model with a traversable wormhole is considered from the view point of Visser’s massive gravity theory. If the matter in the universe is assumed to be divided into two parts, the cosmic part, which depends on time only, and the wormhole part which depends on space only, a late-time acceleratedly expanding universe with a traversable wormhole and dominated by phantom energy is obtained.

Visser 巨大引力产生的可穿越虫洞的加速宇宙

在这封信中，具有可穿越虫洞的弗里德曼-罗伯逊-沃克模型是从维瑟的大质量引力理论的角度考虑的。如果假设宇宙中的物质被分为两部分，宇宙部分只依赖于时间，虫洞部分只依赖空间，这是一个晚期加速膨胀的宇宙，有一个可穿越的虫洞，并以幻影为主获得能量。
