论文摘要
重力耦合$ 1/g $的大小和符号取决于标量，费米子和向量场的不同贡献之间的关系。原则上，在某些假设的宇宙中，这可能给出$ 1/g $的零和负值，而费尔米金和玻色子物种之间的关系正常。我们考虑与重力有关的不同猜想，例如由重力，熵重力和最大力引起的波函数塌陷。我们发现其中一些在零或负$ 1/g $的宇宙中不起作用，因此不能被视为通用。因此，重力耦合到$ 1/g \ leq 0 $的扩展提供了对拟议重力理论的普遍性的测试。
The magnitude and sign of the gravitational coupling $1/G$ depend on the relations between different contributions from scalar, fermionic and vector fields. In principle, this may give the zero and negative values of $1/G$ in some hypothetical Universes with the proper relations between the fermionic and bosonic species. We consider different conjectures related to gravity, such as the wave function collapse caused by gravity, entropic gravity, and maximum force. We find that some of them do not work in the Universes with zero or negative $1/G$, and thus cannot be considered as universal. Thus the extension of the gravitational coupling to $1/G \leq 0$ provides the test on the universality of the proposed theories of gravity.
