引力波的传播是在宇宙学的背景下探索的。它明确地表明，引力波的传播可能会受到影响的介质。结果表明，在热辐射中，广义相对论中引力波的传播不同于标量张量理论中的引力波传播。研究了引力波在均匀磁场中的传播。结果发现，宇宙磁场对引力波的传播有着不可忽视的影响。对旋涡星系NGC 6946的效应作了相应的估计。
The propagation of gravitational waves is explored in the cosmological context. It is explicitly demonstrated that the propagation of gravitational waves could be influenced by the medium. It is shown that in the thermal radiation, the propagation of gravitational waves in general relativity is different from that in the scalar-tensor theory. The propagation of gravitational waves is investigated in the uniform magnetic field. As a result, it is found that cosmic magnetic fields could influence the propagation of gravitational waves to a non-negligible extent. The corresponding estimation for the spiral galaxy NGC 6946 effect is made.
