Can all binary star systems merge in infinite time by emitting gravitational waves? The answer is no. The orbital radius shrinks from the gravitational wave emission; simultaneously, the universe is expanding if the Hubble–Lemaître law is universal on all distance scales. Inside the gravitational bound state, the cosmic expansion becomes visible near the critical radius given by the equilibrium between the orbital decay and expansion. The equilibrium condition gives a different deceleration parameter ($q=-3$) from the cosmological observations ($q_0\approx -1∕2$), which indicates binary systems could have a smaller expansion rate ($H_0∕6$). This model can explain a deviation from general relativity (the excess $\dot{P_b}$) in the binary pulsar PSR B1534+12. It is also supported by PSR B1913+16. This means that the expansion of the universe is characterized by viscous uniformity, which has a constant of $\ddot{a}∕\dot{a}$. By applying this relation to PSR B1534+12, $H_0=66\pm 37$ km ${\mathrm{s}}^{-1}{\mathrm{Mpc}}^{-1}$ is obtained.

所有双星系统都能通过发射引力波在无限时间内合并吗？答案是不。轨道半径因引力波发射而缩小；同时，如果哈勃-莱默特定律在所有距离尺度上都是通用的，那么宇宙正在膨胀。在引力束缚态内部，宇宙膨胀在由轨道衰变与膨胀之间的平衡所给定的临界半径附近变得可见。平衡条件给出了不同的减速参数（$q=-3$）从宇宙学观察（$q_0\approx -\mathrm{1个}∕2$），表示二进制系统的扩展率可能较小（$H_0∕6$）。该模型可以解释相对于广义相对论（超出$\dot{P_b}$）在二进制脉冲星PSR B1534 + 12中。PSR B1913 + 16也支持它。这意味着宇宙的膨胀以粘性均匀性为特征，粘性常数为$\ddot{\mathrm{一种}}∕\dot{\mathrm{一种}}$。通过将此关系应用于PSR B1534 + 12，$H_0=66\pm 37$ 公里 ${\mathrm{s}}^{-\mathrm{1个}}{\mathrm{Mpc}}^{-\mathrm{1个}}$ 获得。
