- W2335868888 abstract "Brans-Dicke理论和f（R）理论均为不同于Einstein广义相对论的修正引力理论,并且在Brans-Dicke理论参数ω=0时能够回到f（R）理论.人们在Brans-Dicke理论框架下研究得出只有-3/2〈ω〈-4/3才存在可穿越虫洞,ω=0时没有;然而,f（R）理论中已经证明确实也存在可穿越虫洞.为了解决上述所谓的矛盾,有文献修改了Brans-Dicke理论中的某些函数,从而改变ω的取值范围.仔细分析发现,文献中探讨的是对应不同Φ（r）,b（r）的可穿越虫洞,自然会给出不一致的结论.本文对2种修正引力理论中的可穿越虫洞问题进行了澄清,明确了各自虫洞解的讨论前提条件." @default.
